Tools of Thought: The Whole Enchilada

A home made salad. NOT an enchilada.

This is NOT an enchilada.

This is a salad.

Do you like enchiladas? I do. I like the combination. It’s much better than just the corn tortilla. It’s better than just eating sauce by itself. And, although I like the fillings, even the fillings are better to me when they are part of the whole enchilada. Sometimes, things only “work” when all the ingredients are present.

Do you think it’s safe to drink and drive? What if I told you that 13% of the drivers involved in fatal traffic accidents had been drinking? Would that convince you that drinking and driving don’t mix?

It shouldn’t. Not by itself. Not only does that statistic, in and of itself, not show causality, it does not even show correlation!

What else would you need in order to show that there was at least a correlation between drinking and driving? You would need to know what proportion of people who were not involved in fatal traffic accidents had been drinking. What if that percentage were 50%? What if it were only 1%?

Let’s take another example. What is the cause of your back pain? Imagine that you went to the doctor and that you had an MRI and it showed that you had a bulging disc or some other back abnormality. Your doctor tells you that you need surgery to fix the bulging disc and that this will get rid of your pain. In fact, the doctor says that 50% of the people who have back pain have a bulging disc or other spine anomaly. What can you conclude from this about the relationship between spine abnormalities and back pain? Nothing. Not yet.

You cannot logically conclude anything from this statistic in and of itself. You have to know what percentage of people who do not have back pain also have a spinal abnormality. What if it’s exactly 50%?

What if it’s only 1%? If it’s only 1%, it would seem that having a spine anomaly might be a good indicator (though not necessarily the cause) of potential back pain.

What if 90% of the people without back pain have bulging discs? Then, it might seem that having a spine anomaly is a good thing!

Once again, before we can even establish that there is a correlation or association between back pain and spine abnormalities, we must know four numbers:

How many people have back pain AND a spine abnormality.

How many people have back pain and NO spine abnormality.

How many people have NO back pain AND a spine abnormality.

How many people have NO back pain AND NO spine abnormality.

Then, we can test these numbers of find out whether there’s a statistical association between back pain and spine abnormality. Even if we find that there is a statistical association between the two, it would not prove that the abnormality causes the back pain. For example, it might be that some other factor is responsible for both. For instance, it might be that people who regularly run, swim, walk, or otherwise exercise have far less back pain and far fewer spine abnormalities. Conversely, it might be that people who experience back pain exercise far less and this lack of exercise is what causes more spinal abnormalities.

Or, it might be that older people have both more spine abnormalities and more back pain. It might really be age that causes an increase in both.

But be careful. If you take a snapshot in time, it might be true that today’s old people have more spine abnormalities and more back pain than today’s young people. But does that prove that age itself is to blame? No. It might be that people who are old today were exposed to more pollutants than younger people. Or, it might be that people who are young today are exposed to many more artificial preservatives and that one of these actually helps prevent spine abnormalities and back pain.

The point is not that science is impossible. It isn’t. But neither is it trivial.

Most people who are scientists were good in science and math and they enjoyed it. While most people were struggling through science, some people, like me, loved it. In the first grade, we had a “science text book.” I found it fascinating. But I didn’t stop there. I went to our local public library on Arlington Street, and discovered that they had our textbook on the shelves — but right next to it, they also had the science text books for grades two through six. I read all of them in order and immediately the day I discovered them.

My grandfather subscribed to Sky and Telescope, Scientific American, and The Natural History Magazine. I began reading these at an early age. If I didn’t understand something, Grandpa would explain it to me. By the third grade, I was very familiar with much of the simple “nomenclature” of anatomy, paleontology, astronomy, biology. I read 2-4 science books every week during my childhood. Mr. Wizard was one of my favorite TV shows. He was the “Bill Nye” of the 1950’s. I got a chemistry set and joined another “club” that sent a different science experiment every month.

Most, but not all, people who are scientists today also loved science as kids. And, in high school, they — like me — continued to study and read about science. And most of them took further science and math courses in college. And most of the people who are “scientists” then went to graduate school and studied science for another four or more years. Graduate school for science is the intense study of science. The grad student doesn’t take physical education or literature courses or “Western Civilization” courses. If they are in a science Ph.D. program, that is what they are studying. Most then do some sort of “Post-Doc” meaning that they get a job, but continue to learn on the job under the tutelage of someone already expert in the field.

One of the things that I find fascinating about current American society is that a huge proportion of people no longer trust what scientists say. Most folks would never go to a forest ranger to have their teeth fixed. They would never go to a professional golfer to have their gall bladder removed. They would not rely on a car mechanic for open heart surgery. Yet, when it comes to climate change or the safety of vaccinations, they are willing to rely on very rich people with a vested interest to tell them what to think over a body of experts who have devoted their lives to learning about a particular field. And the “arguments” of those with vested interests are generally like the opening example. They do not tell the public all the facts or observations needed to make rational decisions.

Let’s now return to our alcohol example. When I was an undergraduate, one of my part-time jobs was as a projectionist. One week I worked all week during spring break for a week-long conference at Case-Western Reserve on the effects of alcohol on driving. It turns out that (as you might expect), there is an association between drinking and being in an accident. People who are scientists not only collected data on this but also studied driving and performance under a wide variety of circumstances.

This is also crucial to understand. Scientist do not typically just go work in a lab by themselves and come to a conclusion. They present and publish their work so that they get feedback from other experts. Of course, like other human beings, they would prefer that their work be “perfect” but at the same time they welcome feedback from these other experts. They don’t just keep asserting over and over and ever more loudly that they are “right.” A person who insists like that will soon find themselves shunned by the scientific community.

So these scientists studying the impact of alcohol on driving came together from all over the world in order to get feedback from each other. Each became a teacher and a student. People who are done with school and don’t want to be students or teachers any more should not really become scientists.

I am very good at finding other people’s typos. I am horrible at finding my own. That’s why I ask other people to proofread my work.

It’s the same with science. Despite having worked for years as a scientist, individuals do still make mistakes in logic. That’s why the consensus of a large group of scientists means more than the conclusion of one scientist who has come to a conclusion.

As for alcohol, some scientists at that conference at Case-Western measured the impact of alcohol on “reaction time” — how quickly a person reacted to a simple stimulus. They measured, for instance, how long it took people to push a button after a light came on. In more “realistic” tests, people sat in a driving simulator and scientists measured how quickly they put on the brakes when a red light came on. In those studies, it turned out that simple reaction time didn’t really become noticeably impacted until the person had three stiff drinks on an empty stomach!

Someone from the insurance industry who had studied accidents in the real world, however, found that even a half drink significantly increased the chances of being the driver in an accident! That’s quite a discrepancy!

But scientists do not throw up their hands at this point and say, “Oh, my! Science is hard! Let’s give up and go watch TV.” No. Scientists find this an interesting problem. Why is it that it takes three drinks to find a significant impairment in reaction time, but in the real world even having half a drink causes a significant increase in accidents? So, they begin to tease this apparent contradiction apart with more experiments.

Does it have to do with particular people? People who agree to participate in lab experiments are not a random group of people from the whole population. They tend to be younger, healthier, and better educated. Could that be part of the apparent discrepancy?

What about mood and motivation? When you come into a laboratory and people measure how quickly you can respond, you might tend to be in a “serious” mood and typically, in our competitive society, you are motivated to be as fast as possible. When you are out partying, you may be in a much different mood. Perhaps your motivation, especially if you are a teen-ager, is to “impress friends” that you are not “chicken.” So, maybe 1/2 drink might induce you to do stupid things that you wouldn’t do when you are sober. At the same time, if you’ve been drinking, chances are that your fellow passengers may have also been drinking so they may cheer you on in your choice to pass on a curve or engage in a high speed race or chase on the highway. Even if they don’t cheer you on, having friends there talking, laughing, and singing may distract you from your main task which is to keep everyone safe. Indeed, it does turn out that while simple reaction time takes three drinks to show a significant slowing, your ability to switch between tasks and to control your attention begins to suffer immediately under the influence of alcohol.

What about back surgery to cure your back abnormality? I am not an expert on backs. Here’s a nice summary of things to think about before having back surgery.

https://www.uofmhealth.org/health-library/aa6282

And I highly recommend the books by John Sarno. Reading this book completely cured my sciatica. Naturally, that doesn’t prove it will work for you, but you may want to try a $10 book before you go under the knife for $10,000, $100,000 or more!

For instance:

https://www.amazon.com/Healing-Back-Pain-Mind-Body-Connection/dp/0446557684

Take-aways:

Don’t drink and drive.

Science works. But it’s not trivial. Experts know more than you do. But the knowledge isn’t inaccessible. It’s not some secret hidden knowledge that scientists want to keep from you. You can become an expert in some field. But it will take time, effort, and an open mind. Or, you can take the word of experts. Or, you can decide that you’d really be okay with a forest ranger fixing your teeth or a car mechanic doing your open heart surgery. Or, you can decide to rely on people funded by fossil fuel companies to tell you whether climate change is real.

Scientists mainly work together to seek the truth. Their “culture” is not to lie, cheat and steal in order to get rich. They get their kicks in other ways.

If someone tries to imply a causal narrative about A causing X, you have to see the number of cases in FOUR categories before you even have evidence of an association. If they only tell you how many cases are in A & X, they are trying to convince you of something, not in having you see the truth. You need to find out how many:

A & X

A & ~X

~A & X

~A & ~X.

Even if A & X are statistically associated, it doesn’t prove causality. Proving causality depends on careful study using a variety of methods to converge on the truth.

If all your doctor tells you is that you have a back abnormality and you have pain, and that therefore you need back surgery, get a second opinion.

Of course, it’s a free country. So far. And, if you want to go to a Mexican restaurant, you’re free to order enchiladas and scrape all the sauce out and then scoop out all the ingredients and just eat the corn tortillas. You are missing out though. And if you then declare that Mexican food isn’t that great…? Well, you do the math. You really should have gone for the whole enchilada.

Resonance

If you have ever pushed your kids on a swing, you know that timing is important. If you add the power of your next push just as the child reaches the apex and begins to fall back, you will swing your child higher and higher with little effort. On the other hand, if you add the power of your next swing at the bottom of the arc just as the swing is moving toward you at maximum speed, you will nearly stop the swing and likely injure yourself and/or your kid. Please don’t try it.

In sports as well, the timing of when you add your effort is critical. In golf, for instance, many beginners think a lot about their hands, probably because we use our hands for many daily tasks such as texting, flipping burgers, playing video games, etc. While the hands are certainly important in the golf swing, they are the last thing to bring to bear on the golf swing, not the first. If you add your hands and wrists at the last moments right before you hit the ball, you will be accelerating the club face as you hit the golf ball. You will have greater velocity and also more stability and hence more accuracy for the shot.

The golf swing is a complex athletic move that I cannot describe in detail. Here’s what is important in this context. Some parts of the golf swing (notice the word: swing) are much like a pendulum. The longer parts of the body (e.g., the arms) take longer to swing on their own. The shorter parts of the body take a shorter time to swing on their own (e.g., the hands). In addition, the shortest pendulum (the hands) is at the end of the longer arm swing. This means that for the arm swing and the hand/wrist moves to multiply effectively, you must engage the hands and wrists toward the bottom of the arm swing when the arms are already moving at top speed.

What is True in Mechanics and Sports is also True in Social Engineering.

If you work in a highly competitive, even cut-throat sales environment, in which there is a long tradition of stealing commissions, grabbing each other’s customers, etc., having the sales manager say something like, “You know what? Let’s cooperate! Put the customer’s interests first, not your own commission” is pretty much useless. A manager’s exhortation to cooperate is a short term high frequency “push” but it will be just as ineffective as trying to start your golf swing with your hands, or trying to push a swing with all your might when your kid is swinging toward you at top speed. If the cultural milieu is cut-throat, the manager’s statement will not be sufficient to change that culture. What the sales people will do is make sure that they have a semi-plausible story ready about how stealing someone else’s commission was really best for the customer.

On the other hand, imagine instead that sales people have shared commissions for years and that the company takes many steps to build social capital and cooperation among everyone on the sales force. Now, the manager may do something publicly to praise an actual instance of cooperation. It doesn’t have to be heavy-handed or over the top. It is a gentle push that adds energy to what people are already doing. This is akin to adding the hands to a good golf swing or adding your swing push just as your kid begins to descend.

Don’t get me wrong. If your house is on fire, you should leave. Grab your kids and pets but don’t bother with last weeks losing lottery tickets.

But — you also need to understand why your house caught fire – perhaps faulty wiring – and why the fire was not immediately doused – e.g., your fire extinguishers are out of date. If you don’t fix underlying problems, your next house is likely to catch fire as well.

If your culture is so materialistic and superficial that a blow-hard sleaze bag who seems to have great material wealth is celebrated no matter how he or she came by that wealth and fame, you may have to deal with the short term problem first, but unless you also deal with the underlying cultural, social, and economic problems, you’ll likely find yourself in precisely the same situation again. The same or other foreign enemies will attempt to exploit those same weaknesses again by finding a different celebrity with deep underlying character defects. Those enemies will push particularly hard during a crisis or an election and they will push particularly hard in the errant directions that society is already trending toward.

The String’s the Thing Wherein We’ll Capture the Conscience of a King

Next time you have access to a piano, try the following experiment. Gently push down the C, E, and G keys above middle C. Keep them pressed down with your right hand and then strike middle C sharply with your left hand and let it go. What you will hear is that the strings of C major (C, E, G) will vibrate for quite a time after you release the middle C key. If instead, you gently push and hold down the D, F, and A keys above middle C, you will hear very little sound coming from them. Why? Because the harmonic resonance of middle C is greater with the C, E, and G than it is the D, F and A keys. Similarly, some people will tend to “resonate” with certain messages more than others will.

This is why, for example, Russian fake news that was meant to suppress the black vote carried false stories to indicate Democratic candidates didn’t care about the “Black Lives Matter” movement, while false stories about how Democratic candidates don’t care about gay rights were targeted toward the LGBTQ community. Of course, even putting Russian election interference aside, candidates typically target their messages to those that will “resonate” with particular voters. For instance, a candidate who believes in an isolationist foreign policy, forgiving student loans, low estate taxes, and better benefits for veterans might focus a speech to a group of veterans on their desire to see better benefits for veterans. The same politician, when speaking to college students, will tend to focus on forgiving student loans. That has been “business as usual” for my entire adult life. What was really new to me in 2108 was this: an entire raft of Republican candidates promoted the idea that they were concerned about making sure that insurance companies covered pre-existing conditions. In fact, they had always voted against it and were suing to make this provision of Obamacare illegal.

Prior to the existence of lying news networks and fake web sites who would echo such lies, politicians of either party would be reluctant to employ blatant lying about their positions because, even putting ethics aside, they would be easily discovered. However, if some of their constituents only believe fake news networks, then such politicians feel that they can lie with impunity The news presented on such networks resonates with what the lying politicians say and resonates with what those viewers want to hear and believe about the people toward whom they are already favorably disposed.

Resonance and the Overly Long Time Lag.

While managing a research project on the psychology of aging at Harvard Med School, I lived in a suburb called Woburn. This rented house had a hot water heating system, and at some point, during a particularly bitter cold New England winter, the furnace stopped working. I could have called in a professional, but instead, I tried to fix it myself. As a part of this system, there was a small gauge that looked a lot like the gauges in a level, but this one was upright and generally half filled with water. I noticed that now, instead of being half filled with water, it was only about 1/10 filled with water. I didn’t exactly understand why this could be problematic but the instructions said it should be half filled with water and there was a valve to let more water in. So, slowly and cautiously, I opened the valve. Nothing happened. I opened it a bit more. Nothing happened. I opened it a bit more. Nothing. I was about to give up and call a repair person. All at once, the little vial began to fill. Yay, me! I turned the valve off because the instructions also said the gauge should not be overfilled. But it kept filling. And filling. Damn! I made sure the valve was closed tightly. It kept filling anyway! Double damn! The gauge exploded! I had been the victim of — well hubris, of course, because I thought I could figure it out — but also a victim of delayed feedback. When feedback is delayed, all sorts of havoc can ensue.

You may have experienced a similar time lag issue with hotel showers. You turn up the hot water and the shower water stays cold. You turn it up more. It stays cold. You turn it up more and it still stays cold. And then…all at once you’re being boiled to death in your own shower and you begin wondering who will find the naked body.

Back in the early days of using LOTUS NOTES, there was a button on my screen that said, “REPLICATE.” And if I clicked on that button, a replication process would start. (Basically, it was downloading my email from the server to my ThinkPad). But sometimes, the mouse click did not register. This might not be a giant issue. In other cases, I would simply click again and this worked for most applications. But in this case, NOTES put up another button, in the same exact spot as the REPLICATE button, that said, “STOP REPLICATION.” The State of the Replication Process, however, was not accurately reflected by the State of the Button on the screen! This was endlessly annoying and could easily have been avoided. There was plenty of screen real estate to put a “REPLICATE” button along side the “STOP REPLICATION” button. Once connection speeds were faster and the computational facilities themselves were faster, this UX issue ceased to be an issue because there was no noticeable time lag between the state of the process and the state of the button.

However, I still run into similar issues with Cable TV remotes. Do you? The time lags associated with clicking something on the remote and something happening on the screen is so long, that you begin to wonder whether the battery has gone dead or whether it is aimed wrong or whether the button was not fully depressed. Indeed, I sometimes wonder whether the entire system is truly electronic. I have begun to believe that the button press actually sends an ultrasonic dog whistle to a pack of hungry weasels who hear the whistle. To them, it’s a signal that they are about to be fed. They begin scampering in unseen cages toward their food dishes. The scampering of their feet is picked up by sensors under the floors of the cages. These sensors cause dials to change in a control room staffed by retired school janitors who push a series of buttons that change the channel or the input designation or turn on captioning, but only after they finish the New York Times crossword puzzle they are working on. Then, and only then, does the desired action take place. But if and only if you’ve been patient enough not to hit the button a second time.

Of course, if you are the user in this scenario, there is a fix. Push the button once and only once. Now, go outside and run around the neighborhood for fifteen minutes before interacting a second time with the remote. Sure, it takes a long time to get to your program but you’ll be in much better shape after just a few months of this regimen.

On the other hand, if you are the designer of such systems, you might consider that it would be less expensive in the long run to replace the ultrasonic dog whistles, the weasels and the retired janitors with an actual system of electronics which, after all, is supposed to run at nearly the speed of light.

The Takeaway

In comedy, timing, as in life, and UX design, and pushing your kid on the swing, and your golf swing, and social interventions, and election interference, and human short term memory limitations, is everything.

Non-linearity

A Chessboard Full of Rice

According to myth, the Emperor’s wise adviser once did him a great favor. So grateful was the Emperor that he begged his wise advisor to take any gift she might like from the vast treasures of gold or jewels, any lands or gardens, any of the Emperor’s many male children to be her companion. However, the advisor answered as follows: “Thank you for your generosity, oh mighty Emperor. I have no need of great material wealth. My needs and wants are simple. I do get hungry and thirsty, of course, as do we all, and sometimes my household runs short of rice. You see this fine chessboard?”

Photo by Pixabay on Pexels.com

“Oh, yes, my wise counselor, it is indeed finely made of gold and silver and I would gladly give you twenty such!”

“Thank you again for your generosity, but I only wish for a some grains of rice. Give me one grain on this space and tomorrow, two grains on this space and the next day, four grains on this space. Each day for 64 days, double the number of grains of rice you gave me the day before. At the end of the 64 days, I will ask for no more.”

The Emperor looked puzzled. “Surely, you must have something more valuable than rice! Name it!”

“No, Sire, that is all I desire. Just the doubled rice will do quite nicely.”

“Well, it shall be so!” And thus the Emperor told his staff that they were to provide a grain of rice for the first day, two grains of rice for the next day and to double the amount each day until all 64 days had passed. At first, it seemed such a pathetic gift for such a great favor.

Even after 8 days, the wise counselor only received 128 grains of rice – not even a bowlful.

Readers familiar with exponential growth realize that on the 64th day, the Emperor has promised to deliver 2**63 grains of rice. This is not only more rice than the Emperor had at his disposal. It is more grains of rice than exist in all the kingdoms of earth. To be exact, the last payment is meant to be 9,223,372,036,854,775,808 grains of rice while the total is one less than 2**64. To put the matter scientifically — it’s a lot of rice! Much more than exists in the world.

How would you like the story to end? A wise Emperor, to my mind, would thank the counselor after a couple weeks and say, “I see, oh wise Counselor, that you used my gift to give me another gift to enhance my wisdom. For I now understand that what seemed at first an easy thing to do is actually quite hard. Doubling soon undoes even the richest king. I will keep this in mind when I think about interest rates and population growth.”

A crummy Emperor, on the other hand, might say, “I offer you a gift and you see fit to embarrass me by making me agree to an impossible task? Boil her in oil!”

The Lily Pad Pond Puzzle.

Beside my house is a pond. In this pond, a lily pad began to grow. Every day, it doubled in size. On day 20, it completely covered the surface of the pond. The surface of the pond is 400 square feet. How many days did it take to cover half of the pond?

At first glance, you might think this problem is insoluble because you don’t know how big the lily pad was initially. In fact, you don’t even need to know how large the pond is. It will cover half the pond on day 19.

The Ping Pong Table Ping Pong Player Population

When I began at IBM Research in 1973, I soon discovered that a fair number of researchers were avid table tennis players. At lunch time, somewhere between six and twenty researchers would show up to play. There were two tables and some small amount of room for spectators to stand on the edges of the two ping-pong rooms and watch. Our rule was that if a person won, they would stay at the table and a new challenger would play. However, if you won three times in a row, you had to sit down regardlessly. I didn’t go over every lunch time, but I went over quite a few times over the course of my first ten years there and there was invariably someone to play with. Sometimes, I had a longer wait time than others, but it was never too long a wait.

Then, because management wanted to use one of the two ping-pong rooms for other purposes, they repurposed one of the rooms. Now, there was only one ping pong table. In the two ping-pong table case, remember, I never had to wait too long nor did I ever go there and have no-one to play. As I said, the number of players varied between somewhere around six to twenty. What is your prediction about how many players showed up when there was only one ping pong table?

Here’s what happened. The first day after this change happened, I went over and about fifteen people showed up. I, like everyone else, waited a long time for a game. Our “official” lunch hour was actually 42 minutes and the building was a five minute walk away. So, if you had to wait a half hour for your chance to play, it really wasn’t that much fun. In addition, there were some more subtle effects. All the players were good, but there some substantial differences in skill level. People tried to arrange it so that they played someone at about the same level. WIth only one table, this was trickier. In addition, when a relatively large number of people showed up, it was too crowded for everyone to see the match without interfering with play. It happened that I was too busy to go for a few days. The next time I showed up, no-one was there. Some of us talked about trying to “organize” the ping pong to insure that enough people showed up but everyone was busy and no-one wanted to take this on. Scheduling researchers is harder than you might think. It was hard for people to make a commitment to show up at noon because a meeting might run over, their manager might give them extra work, etc. The number of people showing up swung wildly for about two weeks and then stabilized.

At zero.

What had been a vibrant community with two ping pong tables did not stay the same size, or shrink to half when we were limited to one table. It went to zero.

Warring Positive Feedback Loops.

We’ve already talked about “positive feedback loops” which are also known as “vicious circles.” Sometimes, there are actually (at least) two positive feedback loops hiding beneath what appears to be a stable system. In the Case of the Missing Ping Pong Table described above, one positive feedback loop was simply that when you went there and had a good time through some combination of watching good matches or playing yourself, you were more likely to go there again. There was also a positive feedback loop that was more of a social nature. The more people who were there, the more likely it was you would find a good or interesting match. It was also more likely to be able to find someone you wanted to have a conversation with although the venue prevented this from being a big part of the adventure. Another way that having more people there increased the chances that more people would be there the next day was that it was kind of exciting to have a larger audience watching, cheering, throwing the ball back when the ball crept under the radiator after pin-balling around for awhile after a decent slam.

At the same time, there were other feedback loops, sometimes of the same factors but in a different range. For instance, beyond the point of having the periphery of the playing field covered one or two deep, additional spectators added only a little excitement and they were more likely to infringe on the needed space around the table. In addition, while the first ring of spectators felt very much a part of the action, the experience for the second ring of spectators was far less engaging. While I mentioned above that more players meant a better change of finding a good match, it also meant that one had to wait longer between matches. The worst case scenario, of course, is that you are the only one who shows up.

Behind Every Abstraction are a Host of Personal Stories.

Yes, you can practice against the wall, and I did this a few times, but it is significantly less fun than a real match. I love to serve, for instance. I have a raft of difficult serves. Just to give you one example, with most set-ups, I can hit the right side of the ball so thinly that I put enough side-spin for the ball to appear as though it isn’t even going to hit the table on the second side, but it does; it curves radically back around the left. Sometimes people are so surprised that they miss it entirely. Even if they get there, the sidespin often makes them hit it off the table or the curve causes them to mis-hit the ball on their thumb or finger. I can also add a fair amount of top-spin or under-spin as well. Anyway, I didn’t get to do any of that just hitting the ball against the wall. The wall was not perfectly smooth either. So I might hit three of four shots and then the ball would hit a little imperfection in the plaster and careen off to scribble scrabble along the floor and then crawl under the radiator. It’s the kind of annoyance that everyone has experienced. And if someone else is there, you can kind of glance at your friend who nods nearly imperceptibly as you get down on your hands and knees and stretch your fingers into the territory of God-knows what spiders or broken glass and feel around through the grit and dust until you retrieved the ball. And that little glance and that little nod actually make quite a difference. If you’re on your own, it’s not any fun at all. It’s just an annoyance. The only reason I even bother to hit against the wall is to learn to keep focus for extended periods of time. For this, it is good practice and a good challenge. But, if I’m interrupting this to go fish my hand into a pile of dust every couple minutes, it isn’t so likely I’ll come back.

These various factors were all in a dynamic balance so long as there were two tables. When the tables went from two to one, however, what had been a stable equilibrium became a very unstable one. Eventually, of course, it did find a new equilibrium point and that was zero. To crawl out of that, one person might show up. But most of the time, they were the only one. So, they would be less likely to come again. Even if two showed up, since no-one could play every day, you might still find yourself wondering whether someone would be there the next time.

You might have read this whole story and wondered why the hell this building full of Ph.D.’s couldn’t get their act together and arrange some matches. It’s an interesting question and here is my personal opinion. When it came to these brilliant scientists and engineers, they came from every part of the globe and they came in all shapes and sizes. Some were vastly overweight and others were ultra marathoners. But the ones who liked to play table tennis were, by and large, athletic and “hyper” – an impatient lot. What all of us really loved was working to find out the truth. And, these truths that we sought were ones the company that we worked for wanted us to seek. True enough, but by the same token, that meant the truth found and utilized would make people’s lives better in some way in the not too distant future. But working in a corporation also meant doing a bunch of administrivia. So, the ping pong set in particular, wanted to get up from their intense sedentary mental and administrative work and play hard at something completely physical and different. The last thing any of us wanted to do was add more administriva to our lives.

The Takeaway

It’s easy and common to assume implicitly that the systems you deal with are linear.

They often aren’t.

Things can go out of control extremely quickly (into a dominant positive feedback loop) once the dynamic equilibrium is disturbed.

Would the invention of the iPhone have kept the ping pong community going?

Another takeaway: there are two quite distinct ways of analyzing that are going on in the essay above: a fairly abstract one (even if it uses concrete examples like rice and lily pads) and a very concrete and experiential one. In my experience, both of these modes are useful and valid and if taken together give a fuller picture of what’s going on. My experience in this was mainly in human computer interaction but I think it is equally true for many in law, medicine, management and many other fields. What’s your experience?

Fraught Framing: The Virulent “Versus” Virus

Fraught Framing: The Virulent “Versus” Virus

Like most of us, I spent a lot of time in grades K through 12 solving problems that others set for me. These problems were to be solved by applying prescribed methods. In math class, for example, we were given long division problems and we solved them by doing — you guessed it — long division. We were given history questions and asked who discovered [sic] America and we had to answer “Christopher Columbus” because that’s what the book said and that’s what the teacher had said.

Even today, as of this writing, when I google “problem solving” I get 332,000,000 results. When I google “problem formulation” I only get 1,430,000 results — less than 1%. (“Problem Framing,” which is a synonym, only returned 127,000). And yet, in real life, at least in my experience, far greater leverage, understanding, and practical benefit comes from attention to problem formulation or problem framing. You still need to do competent problem solving, but unless you have properly framed the problem, you will most often find yourself doing much extra work; finding a sub-optimal solution; being stymied and finding no solution; or solving completely the wrong problem. In the worst case scenario, which happens surprisingly often, you not only solve the “wrong problem.” You don’t even know that you’ve solved the wrong problem.

There are many ways to go wrong when you frame the problem. Here, I want to focus on one particularly common error in problem framing which is to cast a problem as a dichotomy, a contest, or a tradeoff between two seemingly incompatible values. We’ve all heard examples such as “Military Defense Spending versus Foreign Aid” or “Dollars for Police versus After School Programs” or “Privacy versus Convenience” or “A Woman’s Right to Choose versus the Rights of the Unborn Fetus” or “Heredity versus Environment” or “Addressing Climate Change versus Growing the Economy.”

One disadvantage of framing things as a dichotomy is that it tends to cause people to polarize in opinion. This, in turn, tends to close the minds on both sides of an issue. A person who defines themselves as a “staunch defender” of the Second Amendment “Gun Rights”, for instance, will tend not to process information or arguments of any kind. If they hear someone say something about training or safety requirements, rather than consider whether this is a good idea, they will instead immediately look for counter-arguments, or rare scenarios, or exceptional statistics. The divisive nature of framing things as dichotomies is not even what I want to focus on here. Rather, I would like to show that these kinds of “versus” framings often lead even a single problem solver astray.

Let’s examine the hidden flaws in a few of these dichotomies. At a given point in time, we may indeed only have a fixed pool of dollars to spend. So, at first blush, it seems to make sense that if we spend more money on Foreign Aid, we may have fewer dollars to spend on Military Defense and vice versa. Over a slightly longer time frame, however, relations are more complex.

It might be that a reasonable-sounding foreign aid program that spends dollars on food for those folks facing starvation due to drought is a good thing. However, it might turn on in a specific case, that the food never arrives at the destination but instead is intercepted by local War Lords who steal the food and use it get money to buy more weapons to enhance their power; in turn, this actually makes the starvation worse. Spending money right now on military operations to destroy the power of the warlords might be a necessary prerequisite to having an effective drought relief programs.

Conversely, spending money today on foreign aid, particularly if it goes toward women’s education, will be very likely to result in the need for less military intervention in the future. That there is a “fixed pie” to be divided is one underlying metaphor that leads to a false framing of issues. In the case of spending on military “versus” foreign aid, the metaphor ignores the very real interconnections that can exist among the various actions.

There are other problems with this particular framing as well. Another obvious problem is that how money is spent is often much more important than the category of spending. To take it to an absurd extreme, if you spend money on the “military” and the “military” money is actually to arm a bunch of thugs who subvert democracy in the region, it might not make us even slightly safer in the short run. Even worse, in the long run, we may find precisely these same weapons being used against us in the medium turn. Similarly, a “foreign aid” package that mostly goes to deforesting the Amazon rain forest and replacing it with land used to graze cows, will be ruinous in the long run for the very people it is supposedly aimed to help.

False dichotomies are not limited to the economic and political arena. Say for example that you are designing a car or truck for delivering groceries. If you design an axle that is too thin, it may be too weak and subject to breakage. But if you make it too thick, it will be heavy and the car will not accelerate or corner as well and will also have worse gas mileage. On the surface, it seems like a real “versus” situation: thick versus thin, right? Maybe. Let’s see what Altshuller has to say.

Genrich Altshuller was a civil engineer and inventor in the Stalin era of Soviet Russia. He wrote a letter to Stalin explaining how Russian science and engineering could become more creative. A self-centered dictator, Stalin took such suggestions for improvement as personal insults so Altshuller was sent to the Gulags. Here, he met many other scientists and engineers who had, one way or another, gotten on the wrong side of Stalin. He discussed technical issues and solutions in many fields and developed a system called TRIZ (a Russian acronym) for technical invention. He uses the axle as one example to show the power of TRIZ. It turns out that the “obvious” trade-off between a thick, strong but heavy axle and a thin, weak, but light axle is only a strict trade-off under the assumption of a solid axle. A hollow axle can weigh much less than a solid axle but have almost all the strength of the solid version.

One may question the design assumptions even further. For instance, why is there an axle at all? If you use electric motors, for example, you could have four smaller, independent electric motors and not have any axle. Every wheel could be independent in suspension, direction, and speed. No-one would have designed such a car because no human being is likely capable of operating such a complex vehicle. Now that people are developing self-driving vehicles, such a design might be feasible.

The axle example illustrates another common limitation of the “versus” mentality. It typically presumes a whole set of assumptions, many of which may not even be stated. To take this example even further, why are you even designing a truck for delivering groceries? How else might groceries go from the farm to the store? What if farms were co-located with grocery stores? What if groceries themselves were unnecessary and people largely grew food on their own roofs, or back yards, or greenhouses?

For many years, people debated the relative impact of environment versus heredity on various human characteristics such as intelligence. Let us put aside for a moment the considerable problems with the concept of intelligence itself and how it is tested, and focus on the question as to which is more important in determining intelligence: heredity or environment. In this case, the question can be likened to asking whether the length or height of a rectangle is a more important determiner of its area. A rectangle whose length is one mile and whose height is zero will have zero area. Similarly, a rectangle that is a mile high but has zero length will have zero area. Similarly, a child born of two extremely intelligent parents but who is abandoned in the jungle and brought up by wolves or apes will not learn the concepts of society that are necessary to score well on a typical IQ test. At the other extreme, no matter how much you love and cherish and try to educate your dog or cat, they will never score well on a typical IQ test. Length and breadth are both necessary for a rectangle to have area. The right heredity and environment are both necessary for a person to score well on an IQ test.

This is so obvious that one has to question why people would even raise the issue. Sadly, the historical answer often points toward racism. Some people wanted to argue that it was pointless to spend significant resources on educating people of color because they were limited in how intelligent they might become because of their heredity.

Similarly, it seems that in the case of framing dealing with climate change as something that is versus economic growth, the people who frame the issue this way are not simply falling into a poor thinking habit of dichotomous thinking. They are framing as a dichotomy intentionally in order to win political support from people who feel economically vulnerable. If you have lost your job in the steel mill or rubber factory, you may find it easy to be sympathetic to the view that working to stop climate change might be all well and good but it can’t be done because it kills jobs.

If the planet becomes uninhabitable, how many jobs will be left? Even short of the complete destruction of the ecosphere, the best estimates are that there will be huge economic costs of not dealing with global climate change. These will soon be far larger than costs associated with reducing carbon emissions and reforesting the planet. Much of the human population of the planet lives close to the oceans. As ice melts and sea levels rise, many people will be displaced and large swaths of heavily populated areas will be made uninhabitable. Climate change is also increasing the frequency and severity of weather disasters such as tornados and hurricanes. These cause tremendous and wide-spread damage. They kill people and cause significant economic damage. In addition, there will be more floods and more droughts, both of which negatively impact the economy. Rather than dealing with climate change being something we must do despite the negative impact on the economy, the opposite is closer to the truth. Dealing with climate change is necessary to save the world economy from catastrophic collapse. Oligarchs whose power and wealth depend on non-renewable energy sources are well aware of this. They simply don’t care. They shrug it off. They won’t be alive in another twenty years so they are willing to try to obfuscate the truth by setting up a debate based on a false versus.

They don’t care.

Do you?

Imagination

Imagination.

It seems odd to bother to remind people that imagination is a tool of thought. I have four kids and twelve grandkids and they all use their imaginations. I also worked as a camp counselor, Y leader, child care worker in a psychiatric hospital, and a sixth grade science teacher. Kids use their imaginations! In many cases, they do this for “fun” but they also are constantly using their imagination to do creative problem solving.

When I did therapy with adults however, I found that many had convinced themselves that they had no imagination. This is rather sad as well as being completely inaccurate. Furthermore, in the very ways that such adults exhibited neurotic symptoms, they were using their imaginations. But instead of using their imagination to further their enjoyment or to solve problems creatively, they mainly seemed to use their imaginations for one main purpose: to make themselves miserable.

For example, few of us enjoy being stuck in stop and go traffic. As it turns out, you can actually impact the traffic flow around you by driving differently. You can read about how in this link, but you can come to much the same conclusion by using your imagination to empathize with the drivers around you. Instead, the neurotic train of thought goes something like this: “WHY oh WHY are all these people out on the road?! MOVE! Oh, crap, I am going to be late. My boss is going to scream at me. Probably fire me. CRAP! MOVE! I’m going to be late. I’m getting fired. Damn! It’s not my fault. My boss doesn’t care. He hates people who are late. I should have left earlier. Where will I get another job at my age? I’m sunk. Once I lose my job, my spouse will leave me too. Crap. He won’t write a good letter of recommendation. Should I get off the highway and take surface roads? That might make me later. Damn! I’m sunk. Life sucks!”

That train of thought certainly uses imagination!

But in all the wrong ways! That person is not using imagination to enjoy the moment, but using imagination to quite literally make themselves miserable. And it isn’t just the commuter. Plenty of people use their imagination to “awfulize” about situations. They think of the worst possible outcome and then imagine that that worst possible outcome is bound to happen.

Instead, if you are in a situation that you can’t change, you could use your imagination to have some fun. So you’re stuck in traffic. There are literally a million things you could do instead of writing a tragic screenplay in your mind’s eye. I won’t list all million, but here are a few. You could design a better transportation system. You could construct a joke to put your boss in a better mood. You could turn on the radio or listen to a podcast or a book on tape. You could look at the scenery. You could make up a rather salacious spy thriller about the people around you who are also stuck in traffic. And so on.

So too, in solving problems….hold on… someone’s at the door. I’ll be right back.

——————————

Well, that was weird! Two of the characters from my last blog series came to the door! They wanted me to hurry up and finish this series on tools of thought so they can come back to life. I had to explain to them that my translator is on vacation and that there’s nothing else to write until more of the myths can be decoded. Right now, there is growing interest in recent, though mythological, archeological digs that will give us further clues about the Veritas. My own command of the mythical Veritas language is extremely rudimentary and I’m not even absolutely sure I understood correctly what they were asking. But I am sure it was She-of-Many-Paths and Shadow-Walker. It was definitely them, more or less as I pictured them, but taller, and more ripped than I had imagined. It’s also clear that the two of them are more than friends. Anyway, they seem to be of the opinion that I need to write their myths so that we real humans can avoid making the same errors that people made in their mythical universe. I don’t quite see how that’s possible, but I will use my imagination to try to understand how it might be done. I hope they don’t bother my neighbors.

—————————————

Meanwhile, back to the catalog of thinking tools in general and to the use of imagination in particular. Under some circumstances, of course, it is a useful skill to use imagination to think of what can go wrong. I use imagination in this vein for example, when asked to evaluate something from a user perspective. I try to imagine how various icons, words, transitions and so on can be problematic for users. Even though I am pretty good at that, when users are actually observed in real life, they still manage to demonstrate problems that neither I nor anyone else on the design team had thought of!

Even in UX work, it is also important to use your imagination to think of additional opportunities. “You know, we’ve been thinking about this calendar application as a passive recipient of the user’s information. But some users might also like seeing a weekly summary of their activity in different categories.” Or, you might think, “Suppose we tie the calendar in with the message system. The system knows where the user is; we could send a reminder when it’s time for them to leave for an appointment.” Or, you might think, “In some places the time to drive somewhere depends on traffic and weather. We could tie this calendar and reminder in with the map and weather apps to give better estimates of when to send a reminder.” Such musings could result in a better product. Of course, timing is important as well. Your colleagues will tend to appreciate these thoughts a lot more if you are not currently in beta test but instead at the conceptual design phase!

Even knowing that, your imagination might be more likely to kick in later in the project because the application seems more real. You can imagine the reactions of your colleagues and frame your response this way, “Trying this app makes me realize that we can make a number of enhancements in version 2.0, 3.0 etc. I’m going to start this shared file of potential additions, changes, and enhancements that we can all contribute to. We should take a look at this when we are doing 2.0 brainstorming.”

More generally, there are many possible triggers for using your imagination and you may find that some kinds of triggers are more fun for you. For example, you might read fiction and you enjoy following along with the story being presented. This requires a lot of imagination work.

You can also start with a goal or even desire and work outward from this internal state to imagine ways you might accomplish your goal or fulfill your desire. But you can also work inward. You look at what is before you; e.g., a computer screen like the one I am looking at now and ask yourself how it might be different in the future.

Such musings can follow a thread based on the characteristics. The screen is flat, for instance. What if it were curved, or dynamically reconfigurable, or foldable or moldable? What if I could shrink the actual screen depending on circumstances? You can inject your screen (and possibly yourself) into a different and unusual situation. What if I had the screen available on the tennis court? Well, I could project things on my glasses; e.g., as I walk over to retrieve a ball, I could be reminded of how to hit a kick serve. What if I had special lenses that I could pass over any word or icon on the screen? One might give me the history of any given word. Another might give me the definition. Another might give me alternatives that are more esoteric or are easier to understand; more general or more specific; more positive or negative in tone. Another tool might enable you to select a sentence, a paragraph or an entire article and ask, “Who has written similar things before?” Even without AI, a purely statistical approach might lead you find out about people with similar interests.

Another way to practice using your imagination is to pose a question or see how two things are or could be related. On the table beside me are a number of objects: a set of keys, an iPhone, a coffee cup, a checkbook, two of the books I wrote, copies of some papers that I reviewed for a recent conference, a quarter, some business cards. How could these be combined? It doesn’t necessarily matter at this point that the combination is feasible. Let’s just try it.

Putting together a set of keys and an iPhone suggests to me having an app wherein I could photograph all my keys and then, if I lost any (or all!) of the keys, I could have one 3-D printed at a local store or my home 3-D printer. I can also imagine that for another layer of security (at a cost of inconvenience) my iPhone would not turn on unless I took a picture of a particular physical key. A coffee cup and a checkbook seem to belong to different worlds indeed, but that only makes it more of a fun challenge! I like coffee. I don’t particularly like writing bills. On the day before the bills are due, perhaps the coffee machine might not deliver coffee till I wrote the bills. This strikes me as too controlling. For me, it might work better to have an ironic message delivered on the coffee cup such as, “Have a nice day! And save the insane interest rates for paying $25 a day late by paying your bill on time! Or, make some rich banker even richer. The choice is yours!” This approach would not be everyone’s “cup of tea” but that doesn’t matter. The point is to reawaken your imagination.

What about a quarter and two books I wrote? I could offer a 25 cent rebate. I could write about about the history of the quarter. I could mail people books with a quarter inside. I could make an advertisement about The Winning Weekend Warrior that is aimed at tennis players and suggest that every time they lose a set, they put a quarter in a piggy bank. When they get to 40 quarters they can buy my book. I can design strategy and tactics sheets for different sports that are sold separately. The reader/user places quarters on the sheet to reinforce strategy. In tennis, for instance, such a sheet might be static and the user could use four quarters for the positions of the four players on the court. They could be asked to select smart shots, given the positions. Similarly, I might have 4 or even 18 sheets for golf and on these sheets I would show the slope and terrain and ask people to put the quarter on for their target. Eventually, I imagine, there is a way to capture the data of how the player actually hits the golf ball on real courses and that could be incorporated into what the best shot is for that particular player. This data could also be used as input to computer golf games so that a player might use the game to help select better clubs and targets. We are no longer necessarily talking about my book or about quarters. That doesn’t matter! All that really matters is that I have used these arbitrary objects to trigger my imagination. And you can do the same!

I’m done. Hold on. Doorbell. II see that it’s the Veritas power couple again. I’m inviting them in for coffee. I wonder if they’ve ever had coffee before….

Metaphors We Live and Die By: Part 2

Today, I want to delve further into the topic of metaphors that we often unconsciously adopt. In particular, I want to look at a common metaphor in four areas: disease, business, politics, and and the role of UX in the entire cycle of product development.

Although I am fascinated by other cultures, my experience is overwhelmingly USA-centric. I am aware that all of the four areas I touch on may be quite different in other countries and cultures. If readers have examples of how different metaphors are used in their culture, I would love to hear about it.

Disease is an Enemy to be Destroyed.

In most cases, American doctors view disease as an enemy to be destroyed. In fact, this metaphor is so pervasive that American readers are likely puzzled that I used the verb “view” rather than “is” in the previous sentence. In American culture, there is also a strong thread of another metaphor about disease: “Disease is a punishment.” This latter metaphor is behind such statements as, “Oh, they had a heart attack! Oh, my! Were they overweight? Did they smoke?” Perhaps I will consider this more fully another time, but for now, I want to examine the view that disease is an enemy to be destroyed.

It seems as though it is an apt metaphor. After all, aren’t many diseases caused by other organisms invading our bodies and doing harm? There are many examples: bacteria (Lyme Disease, pneumonia, ulcers, TB, syphilis), viruses (herpes, Chicken Pox, flu, common cold), protozoa (malaria, toxoplasmosis) or even larger organisms (trichinosis, tapeworms, hookworm).

Photo by Pixabay on Pexels.com

When it comes to considering causality, our thoughts usually travel along linear chains of causes. So, we may admit that while Lyme disease is “caused by” Borrelia bacteria, the “deer tick” that spreads the disease is also partly at fault. Similarly, although malaria is caused by a protozoa, the most effective prevention is to reduce the mosquito population or to use netting to keep the mosquitos from biting people. Similarly, you might try to prevent Lyme disease by wearing light clothing, using spray to keep the ticks off, checking for ticks after being in tick infested areas, etc. So, even in common practice, we realize that saying that the little organism causes the disease is an over-simplification.

Once one “gets” a disease, however, the most commonly invoked metaphor is war. We know what the enemy is and we must destroy it! I grant you that is one approach that can be very effective, but consider this. The “human” body contains approximately as many bacterial cells as human cells. What you think of as your “human” body is only half human! It is half bacteria! Furthermore, since we all have trillions of bacteria in us when we are well, the picture of treating bacteria as an enemy to be destroyed is at best an over-simplification. In fact, more recently, medical science seems to indicate that under-exposure to bacteria in childhood can make you more not less susceptible to disease. If you use anti-antibiotics to “destroy” the “enemy” bacteria in your body, many of the “good” bacteria necessary for digestion are also destroyed. This sometimes, though rarely, requires exotic treatment to return to health.

In cancer, both doctors and the general public mainly think of the cancer cells as “enemies” who must be destroyed! And yet, it seems that people may often have mutations that could lead to cancer but don’t. There are even very rare cases of spontaneous cures of cancer. What are some alternatives to thinking of cancer as an “enemy” that must be destroyed?

Clearly, I don’t know of a definite answer or you would have already heard about it on the news! But let’s consider a couple alternatives. First, instead of thinking you have to “destroy” this enemy, imagine you thought of cancer cells as confused. People get confused all the time. Sometimes, we put them in jail. Sometimes we put them in mental hospitals. Sometimes, we simply teach them what they need to know. Sometimes, we do end up killing them. But it is not our approach to kill someone just because they make a mistake. So, we might seek a way to “re-educate” cancer cells so that they “realize” that they are part of something even larger and more wonderful – the human body! How would one go about this? Using the metaphor of a confused person, we would have to understand just why they were acting confused. Then we would have to provide situations so that they could learn (or re-learn) what they needed to know in order to become a productive member of “society.” We could “remind” a liver cell that, after all, they were born to be a liver cell and they’re potentially quite good at that. We could think of cancer as cells that are misinformed or have amnesia about their true nature.

We might also think along a different line. We could try to discover the best possible environment for these cancer cells to thrive – and then offer it to them somewhere else. For example, perhaps they really prefer an extremely acidic environment. Say you have a skin cancer on the back of your hand that thrives in a really acidic environment. You provide a gradient of acidity next to the tumor and encourage all those acid-seeking cancer cells to migrate into a really acid tube that is next to the tumor. The farther away it gets from you, the more acidic the environment.

You might also think of cancer cells as being rebellious. For whatever reason, they “feel” as though they are not experiencing enough of the “good life” being part of your body so they “take matters into their own hands” and begin leading a rebellion of cells out to steal the food supply and multiply in an unrestrained fashion. A solution might be to “convince” them that they are better off retaining their initial function rather than becoming a lawless gang of cells. I am not sure what the best metaphor for thinking about infection or cancer is, but surely it is worth imagining others rather than sticking to just one based on war as a metaphor.

Business is a Sport.

I treat this at greater length in The Winning Weekend Warrior, but the basic idea is simple. Yes, there are many strategies and tactics from sports that apply to business. But there is at least one crucial difference. Sports are designed to be difficult. They typically require skill and training if you are to do well. The parameters of the sport are fixed at any given time though they will vary somewhat over time. In golf, for instance, the hole is small and the distances are great. Though the rules of golf are complex, there is one over-arching principle. If it would help you to do something, doing that thing is penalized!

If golf were a business, many CEO’s would nonetheless approach it as a sport. They would try to hire the “best people” – that is, people with a proven track record of good golfing. They would then proceed to offer incentives for people to do even better. If people shot a high score repeatedly, they would be fired. Eventually, such a CEO might get good results by having skilled people who are well motivated and well trained. But why? If putting a golf ball in the hole is what gained you profit, simply shorten the fairways, widen the hole, and eliminate the hazards! Of course, as a sport this would make golf no challenge and no fun. Everyone could win. But having everyone win is exactly what you should do to maximize profit. Yet many in management are so taken with the “business is a sport” metaphor that they do not change the situation. Some do “change he game” and with spectacular results. Google and Amazon come to mind.

Politics is War.

If you belong to a political party and believe the “other” party or parties are enemies to be destroyed, you are failing to understand the dialectic value that parties with different views can bring to complex situations. Life is a balanced dance between strict replication and structure on the one hand, and variation, exploration, and diversity on the other hand. A species who had no replication of structure from one generation to the next would die off. But so too would a species that had no variation because the slightest change in environment would also cause the species to die off. So it is with human cultures. If every generation had to start from scratch in determining what was edible, how to get along, how to avoid predators and so on, humans would have died out long ago. On the other hand, if a culture were completely unable to evolve and change, they would also die out. Typically, “conservative” parties want to keep things the same for longer and “liberal” parties want to change things more quickly. There is no obvious answer here. But what is vital is that members of each party see that there is value in the debate; in the dialogue; in the dialectic.

The other party is not an enemy; it is the balance so that you can do what you do best. If you are predisposed toward exploration, science, new experiences, and so on, great! On the other hand, if you are more predisposed toward tradition and loyalty and repetition, great! If you did not have the people of the opposite predisposition, you would have to incorporate all that within yourself. Conservatives are what allows liberals to be liberal. And liberals are what allows conservatives to be conservatives. A huge problem arises, as it has recently in American politics, when one party decides they are just “right” all on their own and “victory” is worth lying, cheating, and stealing to get it. This is not unique to contemporary America of course. History is littered with administrations who were so convinced that they were “right” that they wanted to destroy all opposition. It has always ended badly. Politics is not war. (Though the failure of politics often leads to war.)

UX is All that Matters vs. UX Does Not Matter. Development is war!

As you might guess, neither of these extreme positions is useful. Price matters. Time to market matters. Marketing matters. Having good sales people matters. Having excellent service matters. Having a good user experience matters. It all matters. Depending on the situation, various factors matter relatively more or less.

(Original artwork by Pierce Morgan)

As in the case of political ideologies, it is just fine for UX folks to push for the resources to understand users more deeply; to test interaction paradigms more thoroughly; to collect and observe from more and more users under a wider variety of circumstances. Similarly, while you are pushing for all that and doing your best to argue your case, remember that the other people who are pushing for tighter deadlines, and more superficial testing are not evil; they simply have different perspectives, payoffs, and responsibilities. Naturally, I hope the developers and financial people do not view UX folks as simply “roadblocks” to getting the product out quickly and cheaply either.

The first half of 2018, I tried to catalog many of the “best practices” in collaboration and teamwork. You might find some of these useful if you are embroiled in “UX wars.” You and your colleagues from other disciplines might also find it useful to consider that it is worth taking the time to affirm your common purpose and common ground. You are meant to work together. Development is not war!

Representation

“Choose your words carefully.” We have all heard that advice. It’s good advice and choosing a good representation is key to solving problems, but the general point extends beyond choosing words. Take a few moments now to divide DCXXXV by IX without translating to Arabic numerals. Go ahead. I’ll wait.

PicturesfromiPhone 080

Choosing the “best” representation for a problem depends on the nature of the problem but it also depends on your own skills and experience with a representation. If you have memorized the multiplication tables up to 99 x 99 (rather than only up to 9 x 9), you can use different techniques for multiplication than if you haven’t. If you already know how to program in FORTRAN and LISP, some algorithms will be easier to program in FORTRAN and some will be easier in LISP. But if the only language you know is R, then under most circumstances, it will be far faster and less error prone to use R than to learn another language and then use that one.

Every representation of a real-world situation will necessarily make some features of the situation obvious and other features will be hidden or less obvious. An elevator, for instance, might say, “Capacity: 12 people.” If all of the people are wildly obese, then 12 may not fit into the elevator. The capacity sign is assuming that the people will be somewhat average. If there are 12 adults in the elevator, and one of them is holding a newborn, it won’t make much difference. If there are only 10 people in the elevator and each one has a large suitcase full of gold bullion, there may be room for all 10 to stand, but the total weight of the cargo may exceed the capacity of the elevators, snap the cable, and plummet you to your death. Remember that the next time you get on an elevator filled with folks who have suitcases of gold bullion.

Every representation has its limitations. If you’re familiar with a field, you will hopefully learn to recognize what those limitations are. In a famous book, The Mythical Man-Month, (still worth reading, though it should be called “Person-Month”), Fred Brooks shows that such a metric as “man-month” or “person-month” has serious limitations in planning and executing software projects. Some have paraphrased his message this way: “You can’t use nine women to make one baby in one month.” According to Brooks, who had plenty of experience as a high level manager of large software projects, when management finds that a software project is behind schedule (which is quite often), there are two major reactions of management: 1) require more measurements, reports, and presentations to management and 2) hire more people.

The issue with reaction 1 is partly that it takes time away from the managers and workers in order to make those measurements, prepare those reports and presentations, and to attend the meetings. Beyond that, it puts the focus of attention on those measurements (representations) which will only be at best, modestly correlated with what the real problems are. If, for instance, requirements keep changing, or there are incompatibilities in the requirements, measuring lines of code produced is not only useless in itself; it keeps people from tackling the hard problem. A solution to a hard problem might be telling the client that there can be no more changes in requirements. A solution to a hard problem might be resolving the incompatibility in requirements. One can count lines of code pretty easily. One can count other things like “function points” with a little more work but it doesn’t require getting into the “hard” and people-oriented problems that really need to be solved.

Reaction 2 – adding more people – will put more “resources” on the project. You can easily count the people. You can easily count the hours they work. The problem is that a person-hour is, like the elevator capacity, an over-simplified metric. In fact, it is a much worse representation of the resources on the project than the elevator metric. First of all, studies show that even among programmers with equal training, there are often ten-fold differences in productivity. The second, and even bigger issue is that even really productive programmers who are added late to a project will have to learn about the project: the people, the requirements, and the code base. If these new people are stolen from an existing project, that will also put that project in jeopardy as well. If they are instead new hires, then in addition to all the technical knowledge that they need to come up to speed on, they will also have to learn all sorts of administrivia that will take time and brain space away from the project: how to commute to work, where the cafeteria is, how to fill out time cards. Most likely, they’ll have to attend ethics training, and diversity training, and safety training. Even worse, a lot of the knowledge that they will need to become a productive member of the team mainly exists in the heads of the very people who are doing the programming now! This means that the busiest, most productive people on the project will have to take time away from programming to spend it instead on answering questions that the new people will have.

Even this understated the real impact however. Let’s look at that phrase I just used, “…will have to take time away from programming to spend it instead…” What hidden assumption about representation is buried in this phrase? It gets the reader to think along the lines that time is additive. If I am deeply involved in programming and I get an IM or phone call from a newbie asking me a question about the project, it might take an hour to answer. Does that mean I have subtracted an hour from my own productive programming? No. It’s probably much worse than that. Why? Because I am not a machine, but a human being. It will cost me much more than the hour to get back to the same state of flow that I was in when I was interrupted.

I was involved for a time in looking at programmer productivity for high performance computing using various tools and the X programming language. One of the people I interviewed put it this way: “My manager calls for an hour meeting for 10 am when I am in the middle of a complex [parallel programming] problem. He thinks he’s taken an hour of my time. For him it’s an hour long meeting. But for me, he’s really destroyed the whole morning.”

These representational issues apply far beyond software development. For example, in the USA and in many other countries, we look at GDP as a measure of the economic productivity of the country. But how does this metric shape — or distort — our view of productivity? If a parent stays home with small children and they both love the time together, and the parent uses that time to help grow a loving, educated, productive citizen, it adds to the well-being of the country as well as that child and that parent and that family. But GDP? Nada. If instead, the parent paid money to put the child in mediocre day care, that would add to the GDP.

Similarly, if I go to the grocery and buy a hard, tasteless tomato for myself, I will pay for the growing of that tomato, advertising it, shipping it, warehousing it, displaying it, and for the genetic alterations so that the tomato, while tasteless, is easy to transport without spoiling. Yay me! I have added to the GDP. But if I go to a friend’s house and taste a wonderful tomato, ask for some seeds or a cutting and grow my own heirloom tomato, watering it lovingly with rainwater, weeding around it, and fertilizing it with compost, I have added zero to the GDP. Yet, the tomato will give me more pleasure, not less, than the croquet balls they have in the store.

Representation is a good thing! Humans use symbolic thinking to do many things that would be difficult or impossible without these kinds of representations. But we must remember the limitations and not confuse reality with our representations of reality.

This is not a new phenomenon. In the American Revolutionary War, high ranking British military officers could not understand why the British navy “refused” to navigate their warships up the Bronx River to attack revolutionary positions upriver. If you’ve ever seen the Bronx River, you’ll realize why immediately. But the maps that the British brass looked at showed a navigable river!

Yes, we need to use representation in our thinking. But we also need to think about our representations. You cannot assume that the one that is customarily used is “right” in all circumstances. People of different backgrounds and cultures will often use somewhat different representations of a problem or situation. (This is one of the advantages of diversity). However you do it, it’s worth questioning whether the way you are representing a situation or problem is optimal, or even adequate, for the problem at hand.

Suppose you are measuring “number of user errors” that users make while using a prototype text editor. You move from prototype A which averaged 10 user errors per half hour test to prototype B which only averages 5 user errors per half hour. Yay! You’ve cut user errors in half! But what if the errors you eliminated were all fairly trivial; e.g., people with version A couldn’t figure out how to number their footnotes with Roman numerals instead of Arabic. In version B, that error, along with other trivial errors, was eliminated. But one of the new errors causes the system to crash and all the user’s work to be lost. Have you really made progress?

All errors are not alike. All dollars are not alike. All people are not alike. Not even all tomatoes are equivalent. We constantly over-simplify and yet in some cases it’s necessary in order to deal with complexity. I don’t see how all such errors can be avoided. But it’s crucial for everyone, but especially for managers and executives, to be open to the cases where the representation that is being used has become counter-productive rather than “doubling down” on such errors. Finding and fixing errors of representation are generally harder to diagnose and fix than errors made with a representation. That is all the more reason why everyone, but especially leaders, must be open to changing the way issues are represented.

It is no accident that dictatorships generally result in nations wherein people have both less material wealth and less enjoyment and freedom. A dictator typically refuses to admit mistakes and fix them even if it means murdering someone to make the problem appear to go away. Ultimately, this process ruins any organization. Such a person need not be a national leader. They can be a company manager, a coach, a corporate executive, or a parent. Everyone makes errors, including errors of representation. But a reasonable person is open to fixing it when new information becomes available. You can be like that too.

Regression to the Mean

While working full-time at IBM Research, I was also a Fellow at the Institute for Rational-Emotive Therapy in Manhattan. I wrote an article in 1978 for their Journal, Rational Living. The title was: “Why Do I Self-Down? Because I’m an Idiot?” Indeed, many people put themselves down and it is not helpful. I hypothesized several different causes for this kind of self-slamming behavior. Most of these causes you could probably figure out on your own. But one in particular is subtle and non-intuitive. It is based on a statistical phenomenon which few people know about despite the fact that it is extremely pervasive. This phenomenon is called “Regression to the Mean.”

I want to define this term by explaining some examples. Imagine that you have a new soft drink which contains a combination of herbs that will purportedly make you smarter; e.g., gingko and bacopa. (There is some evidence these may actually work but let’s assume that they don’t or that your tea has too little to be effective). Here’s what you do to “prove” that it works anyway. You give an IQ test to 10,000 people and choose the 50 who score the lowest on the test and have them drink your tea for the next six months. At the end of that time, you give those 50 people an IQ test again and — Voila! The average (or mean) of the IQ scores has almost certainly gone up. Yay! It works!

Or does it? One of your competitors is not too happy about your study. In fact, they aren’t even happy you put your tea on the market. They decide to prove that your tea is not only ineffective but that it makes people less smart. So what do they do? They give an IQ test to 10,000 people and they pick the 50 who score the highest. They have them drink your tea for six months and at the end of that time, they have them take another IQ test. In this case, the mean (average) score is lower than the first time! Ouch! They say your tea causes brain damage!

How can the same tea make people smarter and make them dumber? In this case, it does neither. What is going on? Here’s what is going on. When you measure something, there is always some error. Whether you are measuring your weight, your height, your blood pressure, or your IQ, the measurement is never exactly perfect. Your weight may vary slightly because of atmospheric pressure and more so because of water retention. If you take an IQ test, your score will partly reflect how well you do on such tests in general, but it will partly depend on luck. You may have felt particularly good that day, or a few of the questions might have been on topics you just heard about on TV the day before, or you may have made some lucky guesses. Or, you may have been unlucky on a particular day. You might have had a cold or misread one of the questions or forgotten your morning coffee. On any given day, some people will be a little lucky and some people will be a little unlucky. These things tend to balance out in a large group and if you tested all 10,000 people after six months, then assuming the tea has no real effect, no effect will be shown in the data.

However, if you select the very best scores, you are partly picking smart people, of course, but you are also picking the people who were lucky that day. When you test just those people six months later, they will generally be just as smart but there is no reason to suppose they will be lucky again. Some will be lucky both times, most will not be particularly lucky or unlucky and a few will be unlucky. The average score will be lower. Conversely, if you choose the lowest scoring people, you will partly be choosing people who don’t do well on such tests in general. But you will also be choosing people who were tired, sick, guessed wrong or were otherwise unlucky that day. When you retest, those people will still tend to be people who do poorly on such tests, but they won’t necessarily all be unlucky again. Some will. Some won’t. On average, the scores will be higher than they were the first time.

The phenomenon of “Regression to the Mean” was first noted by Francis Galton in the 1880’s. Tversky and Kahneman, so far as I know, were the first to note that this phenomenon could easily cause managers, coaches, and parents to end up being unnecessarily negative. Here’s how it works. Let’s say you are learning to hit tennis serve. Although you will likely improve in general, over time, there will also be a lot of variation in your performance. Sometimes, everything will work well together and you’ll hit an excellent serve, one that is above your average level. At first, the coach’s natural inclination will be to praise this by saying, “Wow! Great serve!” or something like that. Unfortunately, your next serve, due to regression to the mean is very likely not to be quite as good as that one was. Your coach’s praising behavior was thereby punished. On the other hand, if you hit a particularly poor serve for your level, your coach might say, “Oh, come on. You can do better than that!” If they choose to say such things only on your very worst performances, then, due to regression to the mean, your next serve is likely to be somewhat better. In other words, their slamming you will be rewarded by your doing better the next time. The same general tendencies will apply to managers and parents as well.

The same applies to you! Whatever you are doing, your performance will vary somewhat over time. If you begin by praising yourself internally whenever you hit a particularly great shot, your next shot will most likely be not so great. On the other hand, if you put yourself down when you find your performance particularly bad, “You idiot! How could you miss that!?” Your next shot will tend to be somewhat better. Over time, your positive self-talk will tend to be punished and your negative self-talk will tend to be rewarded.

It’s no wonder then that many managers, coaches, and parents end up saying very negative things about their charges. It’s also no wonder that many people say (or more likely think) many more negative things about themselves than they say positive things.

Is there anything to be done? First, simply be aware of this phenomenon. That is step one. If you are running a study, you need to be careful in selecting. The study about your tea could be fixed by re-testing the entire population; by selecting a random group of 50 rather than the best or worst; or by using a control group who did not drink tea but was retested anyway. When praising or punishing someone’s performance, do not bother with trying to reward or punish outcomes based on one trial. That’s actually a pretty poor way to coach yourself or others in any case. See The Winning Weekend Warrior for more on this. Also watch out for this when you read about various conclusions of other studies. Did the investigators select either the “best” or the “worst” for their study? If they did such a selection, did they talk about the bias this introduces? Did they have a control group?

Meanwhile, treat your mistakes as opportunities to learn, not as opportunities to put yourself down. There’s really no point in self-downing. But if you do find yourself self-downing, remember that it’s common; relax; smile at this human foible; then quit doing it. At least give yourself a break for the holidays.

And, then what?

And then what?

When it comes to increasing the drama in TV crime shows, westerns, and spy thrillers, both the brilliant, evil villain and the smart, brave, good-looking protagonist display one common and remarkable weakness: they rush into action without much thought as to the possible consequences of their actions.

Here’s a scene that you and I have probably seen a thousand times. The hero has a gun drawn and a bead on “The Evil One” but the Evil One has a knife to the throat of the friend or lover of The Hero. The Evil One, as both we in the audience and The Hero know, cannot be trusted. Most likely, The Evil One has caused the death of many people already, is treacherous, and lies as easily as most people breathe. Nonetheless, The Evil One promises to release the hero’s friend or lover provided only that The Hero put down their gun and slide it over to The Evil One. And The Hero complies! Often, The Hero will elicit a “promise” from The Evil One: “OK, I’ll give you my gun, but you have to let them go!” The Evil One, for whom promises mean nothing, “promises” and then The Hero slides the gun over. At this point, The Evil One is obviously free to kill both The Hero and their friend or lover immediately. Instead, The Evil One will begin chatting them up. This allows time for magic, skill, accident, God, unknown allies, or brilliance to turn the tables on The Evil One.

Here’s another scene that we’ve both witnessed. The Hero suddenly finds out some crucial piece of information that lets them know the whereabouts of The Evil One. Often this is an abandoned warehouse filled to the brim with minions of The Evil One. But, it might be the cave deep beneath the island stronghold of The Evil One; a stronghold filled to the brim with his minions. The Hero rushes in with a woefully inadequate force and without informing anyone concerning his whereabouts. He or she confronts The Evil One who not only confesses to past misdeeds but outlines their future plans to The Hero as well.

In the TV series or the movies, the sequence of events is determined by the writer(s) so even though The Hero faces impossible odds, he or she will almost certainly overcome those impossible odds. That makes for an exciting story!

But in life?

In real life, you’ll typically do a lot better if you think about the likely consequences of your actions.

Sometimes, people fail to do this because they have simply never developed the habit of thinking ahead.

Sometimes, people let their wishes completely color their decisions. For instance, an addicted gambler, despite their actual experience, believes that gambling more will result in a favorable outcome for them rather than the truth which would be that there is an extremely small chance that they will win overall.

Sometimes, people are too ignorant to realize that there are potential negative consequences. For instance, when I was a youngster, I had a “glow in the dark” watch and cross; each glowed partly because of radium. I enjoyed putting these right up to my eyes in order to observe the flashes of individual photons. I also put together model airplanes with glue. When I applied too much glue, I dissolved it with Carbon Tetra-choloride. I loved the exotic smell of Carbon Tet. Now, it is deemed too dangerous to be used in this way.

In many cases, it seems to me that people do think about consequences but use an overly simple model of reality on which to base their predictions. In particular, people often treat individuals and social systems as mechanical systems and base their decisions on those mechanical models rather than actuality. For example, your kid does not, in your opinion, eat enough broccoli so you simply force them to eat broccoli. Your “prediction” of the consequences of this may include that the kid will eat more broccoli, be healthier, eventually like broccoli, etc. Depending on the individual child, it may be that none of these will actually occur. In some cases, it may even happen that the exact opposite of your goals will be achieved. The kid may eat less broccoli, be unhealthier, and hate broccoli more than ever. There are many other possible consequences as well. The kid may end up hating meals with the family or hating you or hating the color green.

When it comes to individuals and social systems, it is hard to know what the net effect might be. Often though, the most significant cognitive problem that people have is that they are so sure of their prediction that they base their actions on what they think should happen rather than what actually does happen.

As recounted in some detail in the Pattern, “Reality Check,” instituting a new social reward or punishment system often does indeed change behavior, but not necessarily in the desired manner. If, for instance, programmers are now rewarded on the basis of lines of code written, they might indeed write more lines of code but many of those lines of code may be unnecessary. You might write 1000 lines of code or you could spend time thinking about the problem and then write two lines of code that accomplish the same result. Will you do so if you are only rewarded 1/500 th of the bonus?

Similarly, you may measure the performance of service technicians by how many calls they “handle” during their shift. But if that is the main or sole measure, you may also end up having those service people tend to offer trivial or even useless advice based on insufficient information. In all these cases, if management keeps seeing what really happens, any damage done by having an inaccurate predictive model of what will happen as a result of a change will be mitigated. But in a system, whether private or governmental, where people are mainly motivated to keep management happy by telling them what they want to hear, instead of correcting a poor intervention, the problems caused by inadequate models will tend to multiply, fester, or explode.

So:

Think of possible consequences and try to determine which ones are most likely. Then, observe what really does happen. This helps avoid turning an issue into a disaster and, over time, it also helps you develop more realistic models of reality. It will also tend to put you in the habit of taking a flexible and reality-based approach to your decisions rather than one that is based on a rigid and inaccurate model of how things should be. The latter approach to decisions will not only make you individually ineffective; it will also make it almost impossible to work well with others (unless everyone involved shares the same inaccurate model).

Myths of the Veritas: The Sixth Ring of Empathy.

Photo by rawpixel.com on Pexels.com

The Four, as they were now called by the tribe, despite being rivals, achieved a high degree of esprit de corps. Partly, as they had discussed among themselves, She-Who-Saves-Many-Lives was, from their point of view, completely unpredictable in her tasks. Furthermore, all of them understood that the slightest hint of cheating, bad-mouthing, or even approaching the boundary of good taste might well be precisely that it would likely be the end of their candidacy. While the candidates were being tested primarily on empathy, it was well understood by the entire tribe that it was absolutely critical that the leader of the tribe must adhere to the very highest standards of ethical behavior. Why on earth would a tribe choose a leader of low moral fiber only to set a horrible example for the whole people? For these reasons and because, apart from any thought to consequences, winning at all costs, including dishonor, was simply not a way any of them wanted to live their lives.

Many moons passed and still She-Who-Saves-Many-Lives had not called them together to explain the trial of the Sixth Ring of Empathy. So far, it was a complete mystery. As could be expected, The Four speculated a great deal among themselves, but they realized they were merely wild guesses. The talked, and debated, and dialogued quite a lot about empathy, but they were in the dark as to the actual tasks they would next be judged on.

fullsizeoutput_137a

The Shaman, She-Who-Saves-Many-Lives, for her part, walked here and there throughout the people; helping with what needed to be done; advising mainly by answering question with question; always generating warmth and wisdom by her example. Her being there, each knew in their hearts, was a great gift for all the people and they esteemed her and loved her greatly. Of course, they accepted that her seeking a successor was just another example of the great wheel of life moving around. Yet, it still saddened them to see her gone so they were in no way discomfited to see that the long time before the sixth trial even began stretched on and on.

Unbeknownst to either the tribe as a whole or The Four, the “trial” for the Sixth Ring of Empathy had begun the instant that The Four had been chosen and walked silently back to their tents. She-Who-Saves-Many-Lives knew quite well that everyone, including The Four, did not realize this. And she also knew that each of The Four was spending at least part of their time wisely, becoming better friends with each other and with the nuances of empathy through their mutual explorations and discussions. The Shaman planned to end the “trial” when she had enough evidence for her to decide on who precisely would continue to the seventh and final trial.

fullsizeoutput_1338

The Shaman had been observing many things over the past many moons. She-Who-Saves-Many-Lives had been watching how The Four interacted with each other. Who listened well? Who spoke well? Who thought of things no-one else did? Who had a good heart? Who sought the truth and had the good of all at heart?

She listened to how everyone in the tribe spoke of everyone else, including The Four. She knew how to moderate words heard to the likely underlying truth because she understood the blind spots of everyone in the tribe. She-Who-Saves-Many-Lives had watched the reactions of everyone in the tribe as one or the other from among The Four came near. She-Who-Saves-Many-Lives sought out many conversations with those of the tribe. She would talk of acorns, for example, and then remark on how Eagle Eyes had studied how acorns fell because she had been interested in shapes. This was not the story that She-Who-Saves-Many-Lives was interested in. The Shaman wanted to see the story written in the face and eyes of the person receiving the story.

{Translator’s Note}: At this point in the narrative, there are several more techniques that the Shaman used but those descriptions are filled with “technical terms” of the Veritas and, so far, no-one has much idea at all what, precisely, the Shaman actually did. It seems as though the Shaman is sensing how animals react to the candidates? But that makes no sense. And, it seems as though she is “reading” their faces and body language and, even, tuning into their auras? souls? voices? thoughts? responses? hearts? And, there is a passage that — well — I know it’s crazy, but she watches how music vibrates through these candidates? Or, how they resonate with various vibrations? None of the few remaining on this planet who claim to know anything about Veritas claims to have any knowledge of these arcane and possibly archaic arts. The oddest part is that the whole time I was trying to make sense of it, what came to mind were scenes involving the high-tech scanning from Star Trek!

Although much of the Shaman’s focus was on the most important task of her life; viz., choosing her successor, she also took note of the Friendship of POND MUD and ALT-R. She had hoped they could learn from each other, but she feared that this friendship had taken a turn toward the way of Not-Life where truth is sacrificed as easily as one pulls off an ant’s leg. There were now simply too many reeds of evidence — more than enough to make a basket — that POND MUD and ALT-R were not going to be re-entered into the seeking of the Rings of Empathy. The Shaman knew that they had agreed to disrupt the trial. Fortunately, their planning was still quite vague because, like the rest of the Village, the two of them had no idea that the trial was underway. ALT-R, however, was discovered to be perpetuating one scheme on his own: to sow the seeds of jealousy among The Four and also between POND MUD and Shade Walker. This could help him “control” POND MUD and could well disrupt the entire trial so that the chances of POND MUD and ALT-R regaining a chance at the Rings of Empathy would be increased.

Though very bright, ALT-R was not among those of ever-alert eyes and ears. When he began calculating a plot, he had a tendency to pace while speaking aloud. In such a state, his cleverness peaked. However, in such a state, he could fail to notice such a noiselessly slow-moving person as She-Who-Saves-Many-Lives. The Shaman was shocked. There had been hot-tempered people among the Veritas and those who were occasionally less than truthful when describing their romantic involvements to others. But the Shaman was now observing what certainly appeared to be an actually evil person who was going to subvert the process of succession in order to grab power for himself. He did not see or did not care what such a grabbing of power would do to the tribe, to the people, to the earth.

The Shaman shuffled away as silently as she had come. Perhaps, the time had come for both POND MUD and ALT-R to be banished from the tribe before more evil spread. At this point, She -Who-Saves-Many-Lives happened upon a very perplexed looking young woman: She-of-Many-Paths. She-Who-Saves-Many-Lives stood still, held out her arms before her, hands up, smiled at the youth, and said, “Good Day. Or should I say, ‘Good Day?’ What seems to be the trouble?”

She-of-Many-Paths answered: “It’s nothing. It’s just. Shade Walker and POND MUD seemed to be about to fight over me. And I’m not. I don’t like POND MUD at all. I mean, not that way. But I do like Shade Walker. But Trunk of Tree is beautiful and large too. I just — but they can’t fight for me. I will choose who I want and what did you mean about our children pulling us together? Anyway, it’s really nothing and it’s — you know — just silly stuff among boys and girls, nothing that you’d…I mean that you’d be interested in.”

There was warm humor in the eyes of She-Who-Saves-Many-Lives as she answered. “It’s all right, She-of-Many-Paths, I know you were about to say that I wouldn’t know anything about young love because now I’m an old woman, in fact, a very old woman. Of course, you are quite right. I was never myself a baby or a toddler or a young girl or a very confused adolescent. I fell fully hatched out of a very old and very craggy willow. That’s why my skin is so wrinkled. The bark against my skin all those years before I finally fell out full-grown and blotches as you see me now. So, I would no nothing of the catching of the breath and the full-throttled beating of the heart nor the feeling of melting and the burning skin. But if I had been born a baby and lived a full life, I would tell you one thing and that would be that you may live through all that and some day be lucky enough to be an old lady such as I. But meanwhile, come here. Take my hands. Look into my heart and see what you see in my past.

She-of-Many-Paths walked slowly forward to take the hands of She-Who-Saves-Many-Lives. As she stepped forward, her embarrassment subsided. Of course, everyone is part of the wheel of life, she thought. She imagined She-Who-Saves-Many-Lives as a youth. And then — there she was! She could see her plainly with long black hair and strong limbs. She was taller and her skin was smooth. And, she was in love. And again. And love was like the love that is the very foundation of life and love is terrifying and wonderful and much better than okay. It is Life. She-Who-Saves-Many-Lives grew out of such a love and her parents as well and her grandparents and She-of-Many-Paths felt now quite well-named and terrified at the same time! For she was traveling out in many paths backwards in time, floating through an endless tunnel so it seemed slowly like a maple seed twirling slowly. She-of-Many-Paths could see/feel/hear backwards in time to the first Veritas and beyond to the first humans and beyond and it became almost unbearable because she was no longer She-of-Many-Paths with human eyes and brain at all. She was something else. Animal. Smell. Fear. Eat. Mate. Mate. Mate. Of course she wanted to mate! Now, She-of-Many-Paths staggered backwards, letting go of the Shaman’s hands.

The Shaman spoke to reassure, “I see that you found the way to truly touch the tree of life through the heart of another.”

She-of-Many-Paths stammered, “What…what was that?! I could see, feel, what it was like to be you and … and before you… and it all started slow but then got fast and I was not even me.”

The Shaman spoke again, “You learned to tie your empathy to your imagination in a feedback loop. It feels a bit overwhelming at first, but it is a useful tool.”

{Translator’s Note}: There is a thicker description in the original and, though I know it sounds crazy, the most accurate translation I could come up with is a Superheterodyne receiver.

“Overwhelming,” exclaimed She-of-Many-Paths, “indeed. But, did you actually look like that? Or, is it just how I pictured it?”

“Most likely some combination of those and also how I pictured myself.”

“Do you experience this? Do you … travel, see,” She-Who-Saves-Many-Lives. You will get better at it with practice though you may decide not to learn to use it.”

Shade Walker appeared around a bend and began walking toward them. She-of-Many-Paths looked about as though for an escape route, but it was too late.

The Shaman was the first to speak. “How does it go with you, Shade Walker? How are you and POND MUD getting on these days?”

“Well, actually…” Shade Walker’s eyes darted to those of She-of-Many-Paths. “He seems to want to fight me. Well, over She-of-Many-Paths. I am not afraid to fight him. But She-of-Many-Paths should choose who she wants. What does it mean to fight over her? Also, there’s something else, She-Who-Saves-Many-Lives. I don’t sense that he actually wants to. You well know that I have continued to study the way snakes can feel/see the heat of their prey. And, I sense all the heat coming, not from POND MUD himself but from ALT-R. But I don’t really think ALT-R wants…I don’t know what he wants. It just doesn’t feel right somehow.”

“No, you’re quite right,” said the Shaman. “It isn’t right. I’m afraid something must be done but I am not quite ready to do it. Meanwhile, I need to find Trunk-of-Tree and Eagle-Eyes. Any idea where they might be, Shadow Walker?”

“She-Who-Saves-Many-Lives, I believe Eagle Eyes went to watch Fleet-of-Foot run. She wants to draw the way he runs. She’s talking about his form. It’s a little embarrassing. She’s not interested in his shape, I don’t think. I mean she is, but…let’s see. As for Trunk-of-Tree, he is practicing, as best he can, for the Sixth Ring of Empathy.”

“And, how, Shadow-Walker, does he propose to do that?” queried the Shaman.

“Exactly! We don’t know the next test.” Here, Shadow Walker paused and looked carefully at the Shaman for a hint or a clue. He found none. “Anyway, the way he is preparing is by practicing earlier tests. He doesn’t know what else to do.”

“I suppose not. And, where might he be practicing?”

“That is hard to say. I mean, I know where he is generally, but not precisely. He thinks you may re-ask us to do the first task, but this time testing a finer gradation of empathy. So, he is searching for places where the number of mountain peaks seen will depend on the height of the individual. Frankly, Shaman, it seems far-fetched to me. Of course, if that is the next trial, please don’t take offense. It’s just that every trial so far has been quite different so….well, I have no idea. Well, that’s not completely true. I have an idea but I don’t know whether it’s correct.”

She-Who-Saves-Many-Lives smiled as she asked, “And, what is this idea, Shadow Walker?”

“Well, I think. She-of-Many-Paths and I both think…” he paused to look at the young woman who nodded almost imperceptibly. “We both think that we are in the trial. All day. Every day. It’s not about what we do when we know we’re being tested. It’s about what we do all through our lives and how we relate to other people. At first, it seemed kind of a crazy idea, no offense, but the more we thought about it and discussed it, the more sense it made.” He glanced again at She-of-Many-Paths, who spoke next.

“Some people…some are quite good at dissembling empathy when they know they are being watched, but the real question is, what do they do when they don’t know they’re being watched. And, I have – we have – been thinking that you are somehow watching without being seen.”

“An interesting, idea,” began She-Who-Saves-Many-Lives. “Very interesting. Your curiosity will soon be satisfied. I ask all four of you to come to council fire by my cabin tonight.”

So it was ordered and so it was done. After dinner, the four came to a small fire that the Shaman had set in a small octagon of logs. After everyone was seated, the Shaman began.

“I want to thank you all for coming. Tonight I will reveal the names of those who have successfully earned the Sixth Ring of Empathy. I can see that two of you are quite surprised — so much so that you are bursting with questions. What would you like to know?

Trunk-of-Tree was indeed beside himself and needed to talk, spewing his words forth rather quickly for him. “How can you have a result when we haven’t even begun the trial. We don’t even know what the task is. At least I don’t. What are we to do? Have we already done it? What? I don’t understand.”

Eyes-of-Eagle was equally taken aback but reacted more stoically. “I would also like to understand, She-Who-Saves-Many-Lives. What do you mean? When did we do a trial?”

The Shaman nodded. “These are good questions. As you know, the Veritas put a high value on truth. I have discovered that some among our tribe are attempting to deceive. And though that does not include anyone here tonight, nonetheless, I wanted to see how you employ your gifts of empathy — or not — on a day to day basis, when you are not being tested, but just going about your business hunting, fishing, gathering, conversing, exploring, arguing, helping others, making baskets and tools and so on. In other words, I wanted to learn not what you could do when tested but what you would do, when you were not being tested.”

“Well, I, for one,” explained Trunk-of-Tree, “was trying to improve my skills. My empathy skills. I did our tests over and over trying to see through the eyes of others and feel the hunger of others and see through the eyes of animals. I think I have improved all of these skills. And, also, I tried different ways of how-to. That’s what I’ve been doing. Improving my empathy.”

“Indeed, this is not a bad thing, Trunk-of-Tree. How have you used your skill — your improved skill — to help the Veritas or to help someone among the Veritas?”

“Well,” stammered Trunk-of-Tree, “would there not be plenty of time for that once, if I became leader of the Veritas? That’s your task now, but our task is to learn empathy, right?”

The Shaman looked at the others, “Any other comments?”

Eyes-of-Eagle spoke next, “Well, we have been talking among us a lot about empathy and about what the trial might be. I thought it would involve shape-shifting. I thought we would actually have to change our shape in some way so we could imagine, what it might be like if we were smaller, or older, or more … but I can see your point. Yes, the best trial is the trial no-one knows is a trial. Shadow-Walker and She-of-Many-Paths thought you might trick us like that but I didn’t really take it seriously.”

She-of-Many-Paths spoke, “I did not say it was a trick. Nor did Shadow-Walker. That is how you and Trunk-of-Tree characterized it. I just thought it was a slim possibility since it was taking so long. But then, the more we discussed it, the more I thought about it, the more likely it seemed that at least one of the trials wouldn’t be identified as such. In this way, our natures and choices would be revealed more fully.”

“This is all true,” said the Shaman, “and was indeed my plan. However, I also discovered something I did not know. She-of-Many-Paths has a particular talent that is rare indeed. She can tune into the very Tree of Life through another’s heart. She can connect her empathy with her imagination. And then I discovered that Shadow-Walker can sense the origin passion of a plan. The development of these unusual talents is consistent with my observations that both of them have been thinking about empathy all during their activities. I am therefore giving the Sixth Ring of Empathy to She-of-Many-Paths and Shadow-Walker.

“I need to share one other thing with all of you. I have reason to believe that sometime soon we may have some treachery in our midst. I just ask all four of you to keep your eyes, ears, and hearts open. You can use a broad-net empathy to sense when bad things are about to happen. Use it wisely.”
