Mobility of Body & Mind

As many of you know, I am using fiction (The Myths of the Veritas) to explore how various values interact. In our story currently, two of the Veritas barely escaped a forest fire and in the process, both injured themselves. This limited their mobility led me, not for the first time, to think about mobility more broadly. How does it relate to strategy and tactics in games, sports, and life? Are our concepts of mobility always useful? How else might one think about mobility?

This is also of interest because I recently fell down and broke some ribs. As the saying goes, “It only hurts when I laugh.” But that’s not very accurate. It also hurts to cough, hiccup, stand up, sit down, turn over, and lie down. I began to write about people with limited mobility and then my own mobility became limited, at least temporarily. So, now, I take a very short break from the Veritas and instead riff on mobility.

In college, one of my quad mates, Andy, happened to be an excellent chess player. I had enjoyed chess ever since I was about 10, but I had never actually studied it much. Andy introduced me to Emmanuel Lasker’s chess manual (an awesome and recommended book, by the way) and to think about chess positionally and strategically. Before that, I had mainly relied on “seeing” combinations (an unexpected and brilliant sequence of moves & counter-moves) as a way of winning.

In the process of showing the values of chess, including mobility, Andy introduced me to a game called “Monster.” In this chess variant, one side has all the pieces and plays “normally.” The other side has only a king and four pawns. That’s right. A king and four pawns against a king, queen, eight pawns, two knights, two bishops, and two rooks! It sounds vastly one-sided. But here’s the twist. The side with only a king and four pawns gets two moves to every one move of the other side.

Unless the side with all the pieces plays quite well, it will quickly be overwhelmed by the side with double mobility. Perhaps this should not have been so surprising to me. Imagine you could run twice as fast as a “normally fast person.” In other words, you could run the 100 yard dash in 5 seconds rather than 10 and run 40 yards in 3 seconds. Not only would you be the world’s fastest sprinter, you could also run out most ground balls in baseball; if your basketball team got a rebound on the opponent’s side, they would pretty much be able to just throw the ball to the other side for the world’s fastest fast break. You would be pretty amazing in soccer or American football as well.

Needless to say (?), greater speed isn’t always an asset. In molecular terms, greater molecular velocity means a higher temperature. Humans and other warm-blooded animals employ various mechanisms (shivering, sweating, goose bumps, blood flow regulation, etc.) to keep their temperature fairly constant. If those molecules start moving around twice as fast as they normally do, the organism will quickly die. If the molecules move too slowly, the organism will also die.

As we age, thought, as well as movement, tends to slow down, other things being equal. Of course, other things are seldom equal. If you are highly experienced and well-practiced at something like playing piano, typing, coding, or doing cross-words, you will typically not slow down much and be much faster than a much younger but much less experienced pianist, typist, coder, or cross-word solver.

Life is a dance of opposites; e.g., stability and change; duplication and diversity; movement and stasis. Long ago, our ancestors chose mobility and became animals while another whole branch of life chose stability and became plants. Even so, as time-lapse photography reveals, plants do move. Occasionally, they move much more rapidly as anyone who has touched the “triggers” of “touch-me-not” knows.

Conversely, sometimes, animals move very little; e.g, bears hibernate; caterpillars form a chrysalis; people sleep (though they move during some phases of sleep). The male angler fish is much smaller than the female and spends its life essentially as an immobile parasite perched on the female until their blood supplies merge.

On the whole though, our great branch of the tree of life evolved to move. And, when we do not move, there are problems for us physically. A complication to watch out for with broken ribs, for instance, is pneumonia. Why? For two reasons, I believe. First, because when it hurts to move generally, you generally move less. I won’t be playing tennis for a few weeks. That can affect overall health and decrease the amount of air that I need to exchange with my lungs as well. Second, it specifically hurts to take a deep breath. So, that also discourages me from taking deep, cleansing breaths. It discourages me, but I do it anyway.

It seems as though we may be touching on a general principle here. When an organism believes, for whatever reason, that the result of an action will be pain, it tends not take that action. Sometimes, it will be otherwise goaded into that action to avoid still great pain, but all the while, that organism will procrastinate, avoid, distract, and only take the painful action if absolutely cornered. It’s good to breathe deep even though it’s painful.

This piece of knowledge turns out to be quite useful in understanding the behavior of others as well. If I observe you to be avoiding doing something even though it has an obvious benefit to you, I then tend to assume that you fear something else even more; you anticipate pain. Just to take a random example, let’s suppose that a court demands that you present a piece of evidence and you refuse even though it would be a chance to clear you name. It’s at least a reasonable assumption, that you fear something else more; e.g., that the truth would implicate you in wrongdoing. You would want to slow everything down as much as possible. This would be particularly effective in the court of public opinion because any one particular topic might eventually become boring to the public.

It could work in more minor cases as well. If you are a kid and you steal cookies from the cookie jar, you could take the tack of denying it, blaming your little brother, suggesting the tooth fairy did it, convince your little brother than he should claim he stole them in order to win your favor, etc. There are a variety of tactics that could be employed. Most kids, however, are taught that honesty is the best policy. Although they don’t instantaneously become ethical on that account, eventually most see, by virtue of their own experience, that honesty really is the best policy.

Even for those who continue to lie in their words, their actions typically betray them.

Mother: “Who stole the cookies?”

Kid: “What cookies? It wasn’t me!”

Mother: “Can I inspect your hands?”

Kid (hastily thrusting his hands behind his back): “It wasn’t me! There’s nothing on my hands! No cookie crumbs! No cookie crumbs! (Kid brushes hands together audibly behind his back). Better check on my sister! She probably did it!”

The poor kid continues to lie, but the structure of his actions; viz., to block Mom’s investigation, betrays the truth.

It will pretty obvious to Mom. Unless —unless, Mom went into the room already convinced that sister stole the cookies. Because the body is not the only thing that it takes energy to move. It also takes energy, in some sense, to change one’s mind. It also takes energy to block out the truth, of course, but only at first. If you do it often enough, it becomes painless and effortless.

One nearly universal example is the “blind spot” in the human retina. The place where the optic nerve exits the eyeball does not, itself, have any sensors. If you close your left eye, it appears that your right eye has no blind spot. It seems as though you have “full view” of what’s out there. In actuality, some of what you “see” has been constructed by the rest of your nervous system.

https://en.wikipedia.org/wiki/Blind_spot_(vision)

What other blind spots do we have? We like to be mobile. We’re all in a hurry. But if we have blind spots and don’t even know that they’re there, we might just miss a step and break a rib or two. Maybe we’ve learned to ignore the kid brushing the cookie crumbs from his hands behind his back for far too long. But are we also so blind we cannot see the kid who’s still got his hand in the cookie jar? Yes, that one. The one six inches in front of our face.

It might be painful at first. But take a deep breath. Move the fresh air in and out of your lungs. It may hurt a bit, but it’s a cure that’s far better than the disease.

UPDATE: Today is December 24th, 2024 and I came across the post above first published about five and half years ago and wanted to add some new observations.

I love playing tennis. Now, at nearly 80, my mobility is not nearly what it was when I was younger. No big surprise there. I mainly play doubles. Even so, I often miss shots simply because I cannot get to them. The folks I play with are mostly my age so we have similar mobility issues.

What I find interesting is that many of the folks I play with handle their mobility issues by moving less whereas I believe it’s better to move more. I don’t mean that I move faster than I used to. I can’t. But I move more often and more strategically.

There are several benefits from moving more often:

First, it makes it much more difficult for the opposing team to hit just the right shot. If instead, my partner stays stock still until they realize a shot is coming close to them, it is trivial for our opposition to attempt to hit a shot that neither of us can reach. Conversely, if my partner moves just before they strike the ball, the shot becomes much more difficult for at least three reasons. It is more difficult to calculate the optimal attempted shot. It is also more likely that they will take their eye off the ball and glance at my partner. It is also harder for the opponents to hit the shot with confidence.

Beyond making the opponents job more difficult, if my partner and I are in nearly constant motion are muscles, joints, and nervous systems are being more active. This means, other things being equal, that we’re less likely to injure ourselves and more likely to react quickly and appropriately.

These advantages work best with good timing. If I move too soon or overcommit to a radical position, the opponents could take advantage. Ideally, one moves just before the opponent strikes the ball and stops, in balance, just as they strike it so that once you determine where they are hitting to, you can move without being “wrong-footed” (leaning or moving in the “wrong” direction).

In the longer term, moving more tends to keep you, the player, in better shape. You burn more calories; you use your muscles more; keep your bones stronger, and see things from a broader perspective. Theoretically, I suppose it’s possible to move too much, and wear yourself out, but I don’t see that happening at our age.

These comments manifest for me in tennis right now, but earlier in life, I also played a lot of softball. I never understood why the outfielders in softball typically never move until the ball is hit, particularly in slow pitch. If the “gaps” in the outfield are stable, it’s very easy to hit into them, but if they’re moving, it’s much more difficult. All but the very least fit outfielder is capable of moving with every pitch. In fact, in slow pitch you can actually tell somewhat where the ball is going to be hit by watching the pitch before the hit. If it’s inside, the hitter is more likely to pull and if it’s outside, the hitter is more likely to push the ball late into the opposite field. It’s far from a guarantee, but why not play the averages? In any case, by moving until right before the moment of contact, the outfielder has made their body more active and more able to move quickly than if they’ve been standing stock still for some minutes.

How do you Re-culture a Culture?

We now live (at least in the USA) in such a divided and divisive political climate that I hesitate to bring up something that sounds political but really isn’t. I don’t even have a position, at least as of yet. It’s just a thought I had while I was reaching out to people in India and inviting them to my blog.

Photo by Roney John on Pexels.com

Here it is. The USA has a very competitive and individualistic culture. It’s been that way my whole life, but now, it’s insanely so. For one thing, people spend proportionally much more time watching TV and playing on the Internet than they do interacting face to face. In effect, everyone is “competing” not just with local talent, but with people from all over the country. In a nation of 330,000,000 people, 329,999,999 of them will not be the best runner in the country. The vast majority of people will never be winners. This may be why lotto and the Reader’s Digest drawing may be so appealing to so many.

41494225-657B-4155-ABBC-2438018C5171

But it isn’t just running, and throwing, and high jump where we see competition. We have contests around human activities that have traditionally been mainly about bonding and cooperating, not about competing and winning. We have contests about cooking, and dancing, and singing. I grant you that in the past, small communities might have a dancing contest, once a year. But most of their activity was cooperative activity face to face, and certainly not cutthroat competition. Now, the contest is not part of the yearly festival. The contest is all there is. And, for the most part, the contest is all that is broadcast.

It seems that we here in America, with many exceptions and so on, have a culture of individuality and contest is everything there is. Oh, and of course, money. For instance, for far too many Americans the first question they ask about anything is “how much money?” I’ve seen articles that purport to tell retirees what the best place to retire is. Some of those articles focus solely on the financial aspects. Some articles ask which college provides the best education but all they really talk about is ROI.

We’ve actually accomplished a lot as a nation with this kind of crazy culture. It helped us achieve in terms of invention, discovery, and innovation. But what if the problems of the 21st century are of a fundamentally different nature? What if most of the problems we faced in the 20th century resonated well with a culture that encouraged competition, but that now, as we embark on the 21st century, the nature of problems has shifted. Perhaps now we face problems that require a much more collaborative and cooperative cultural attitude in order to solve?

Naturally, these are large trends that I’m talking about. Not every single problem we faced changed lock-step overnight. Let’s examine some examples though. A 1930’s problem might be: “How can we clear cut this forest as cheaply as possible?” And the logging company that solved that problem “won” and got rich. A 2030’s problem might be framed this way: “Is it feasible to provide material by using this forest in a sustainable and humane fashion? How?” One lends itself fairly well to top-down direction. One does not. The reader can guess which is which.

A 1950’s problem might be: “How can we entice consumers into buying one of our new cars when their old car still works?” A 2050’s problem might be: “How do we provide a transportation system that is effective, efficient, and pleasant for everyone involved?” One is about manipulation and disregards collateral damage. The other collaboratively looks to a sustainable solution without side-effects that are so negative they outweigh the good done by the transportation system.

Can American culture evolve quickly enough to be a partner on the world stage in the 21st century? If not, the absolute best we can hope for is slow decay full of internal bickering and hostility as people point fingers and shout loudly in order to establish blame.

Do we really need to change our culture and change it quickly to avoid that? Or, is the emphasis on competition and individuality still the right way to go?

C9C3EEAF-D862-4222-886F-CCF8950DC6C3

Other countries and cultures are already ahead of us in cooperation. Look at the cost versus benefits of their health care systems for one.

How can we change and work together as a culture to a develop a more cooperative view when we seem to be so divided and competitive? That is a real puzzle.

Do you have a piece of that puzzle? I’d love to hear about it.

Or, do you think we should “double down” on competition and individuality? I’d love to hear about that as well.

Resonance

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.

Negative Space

Negative Space

When you look at a scene, it is natural to concentrate on the objects in the scene. So too, when one begins to design, it is natural to concentrate your attention on the things you put in the design whether those are menus, icons, images, banners, buttons and so on. You tend to give little thought to what is not there because, after all, there’s nothing there!

As your expertise grows, you will find it useful to spend some time and resources thinking about what is not there; the “negative space” if you will. In art, the “negative space” refers to the space around and between the objects. Often, paying attention to the “negative space” can result in a much more interesting and aesthetically pleasing composition. It is a concept that has applications far beyond artistic visual composition however.

Consider music for a moment, or better yet, listen to some and you will note that the silence is just as important as are the notes. Increase or decrease the silence in a tune by a factor of two and it becomes a different, and in most cases much worse, tune.

Photo by Pixabay on Pexels.com

The same can be said of great acting whether on stage or in a movie. The silence while we wait for the actor’s response to some news — while they are saying nothing and possibly even showing nothing or very little on their face, can often be the most poignant and moving parts of the picture. If the actor reacts “too quickly” with no space, we can tell that the stimulus presented is something that they “trigger” on because they are upset about it or trying to deny it. The leading man, for instance, asks a seemingly innocent question on a first date, such as, “So, do you like French Cuis…” “NO!” she cuts in. The audience’s attention is immediately drawn to see what comes next. The response that is too fast indicates a “sore spot.” Did the leading lady want to become a French chef? Did she just end a love affair with a Frenchman? What is going on here?

On the other hand, imagine the leading man, says, “So, do you like French Cuisine?” One beat, two beats go by. No answer. A long pause. The leading lady’s face shows nothing. Perhaps she tightens her lips ever so slightly or frowns to the slightest possible extent. The pause continues. The leading man tilts his head as though to ask whether she’s okay. Finally, we come to expect a tirade about the French or French Cuisine or French wine or … something. Instead, after this long pause, the leading lady says nothing but punctuates her silence with something that sounds like a cross between a humorless laugh and a karate grunt. There are probably no words she could have said which would have intrigued us more than the non-response. We think, “What the hell is going on with her and French Cuisine?”

Speaking of French Cuisine, when you go to a fine restaurant, your focus is on the food. So too is the focus on the chef and the server. But the space is important as well. It is annoying when you are paying good money to have a nice dining experience and you are shown to your table, given menus and then ignored for the next twenty-five minutes. On the other hand, it is equally annoying when your server comes back every 30 seconds and asks, “Are you ready to order yet or do you need more time?” The optimal time to wait between courses is not always obvious either. Some people need or want much more time between courses. Maybe this nice dinner is all they have planned for the evening. The patrons are having a nice quiet dinner with good conversation. They are in no hurry. Just as one of the diners launches into a complex story or joke, the server comes over and interrupts to tell about the specials. Conversely, another foursome may be planning on attending a play and long pauses between courses may mean missing the first act.

The negative space in dining is not just about the timing of events. It is also about the spatial arrangement of the food, the spacing between textures and colors. Often, the artistic arrangement is as much about the negative space as the objects on the plate.

Sometimes, the food itself has positive and negative elements. In a meal with varied and complex and contrasting tastes, for instance, the rice or the bread can provide a kind of “negative space” between the tastier and more salient constituents. These neutral or negative elements allow more contrast among the salient elements than if the more salient elements were enjoyed right after each other.

Negative space is important in architecture, paining, typography, cinematography, the design of user interfaces, culinary arts, music, and the design of other stimuli. It is also important in activity.

One of the first popular video games was called “Asteroids.” In this black and white vector graphics game, you controlled a small space ship that shut bullets in the direction the space ship was aimed. All you could control was the speed and direction of the space ship and whether it was shooting. The screen also showed a number of large, irregular “asteroids” that you were meant to hit. When you hit one of these large asteroids with a bullet, it split into two moderate asteroids. When you hit a moderately sized asteroid with a bullet, it split into two small asteroids. When you hit a small asteroid with a bullet, it disappeared. If you got hit by an asteroid, you would die. There was also a flying saucer who came to hassle you. Anyway, I found that if I focused on all these floating asteroids and trying to not to get hit by one, it was a difficult game. For me, at least, it was much better to visualize a path among the asteroids and try to follow the path. In a way, concentrating on the negative space, helped.

The importance of negative space in sports can hardly be over-emphasized. In American football, the back tries to find the holes to run through. In soccer, players seek paths between. In baseball, the hitter wants to “hit it where they ain’t.” In tennis, beginners often play only during half a point. Their attention is focused on the ball and the opposing player(s). They choose a target on the other side of the court and watch to see how well they hit that target. Just as their opponent begins to hit the ball they shift their attention to their opponent and watch where that opponent hits the ball, scurrying there as quickly as possible so as to hit the next shot. What does such a player do between the time they hit the ball and their opponent hits the ball? They watch! They want to see where the next ball goes. If you are young and fast and your opponent is not well skilled, you can often get away with this process. However, what higher level players do is something quite different though it may look similar. The good player has a target in mind but watches the ball while their mind has the target clearly in mind. By watching the ball, they are much less likely to mis-hit the ball. Furthermore, they are not giving away their intended target with their body language. Perhaps most importantly, long before their opponent hits a return shot, the good player thinks about the open spaces on their side of the court and go to cover the most likely of those spaces.

Many otherwise well-skilled athletes only focus on the game during play. For example, many hitters on amateur softball teams, pay little or no attention to the game while their team is batting until they are “on deck” (almost ready for a turn at bat). This is absurd in the majors, but it’s even more absurd in amateur games. You should be taking this time to learn about the opposing pitcher and about the weaknesses in the opponent team’s fielders. Just because you’re not in the batter’s box doesn’t mean you can’t improve your play. Similarly, in tennis, you can use the time between points to think about tactics and strategy, as well as to mentally “reset” yourself if necessary. Some players wave their hands in front of their face after a point as a reminder/trigger to forget about what just happened and focus on the next point. Some will even turn away from the play, seemingly to talk with their “imaginary friend.”

To close, a very short, short story based on true events in my first trip to Japan.

The Touch of One Hand Clasping

Japan, Tokyo, 1977. I walk crowded streets and beautiful gardens where care is taken for spaces as well as things that grow. I struggle — try to speak Japanese language but usually mispronounce “Key-Ray-Ee-Des” (It is beautiful) as “Key-Rah-Ee-Des” (It is dirty). I tip-toe through minefields of culture steeped in subtlety; lose huge chunks of flesh and karma with my thunderous, blunderous New York strides.

Shin-Ju-Ku: lights dim Times Square into grandmother’s fruit cellar. Row on countless row of Japanese stare hypnotized at small vertical pin-ball game called Pah-Chinn-Koe. This bright hustle bustle hassle hides deeper subtlety, deeper calm, inside, beneath, where foreign eyes can peer not.

I enter Tokyo subway. Then — she enters — total stranger, totally beautiful, black hair, endless eyes. I, of course, having learned small little in my many minefield walks, look everywhere but at her. Better, she looks everywhere but at me. We ride, totally not looking at each other. She stands in middle — nowhere to hold on to — unprotected, beautiful, vulnerable.

Suddenly, train lurches. Simultaneously: she shoots hand out to only spot I can possibly reach while I shoot hand out to only spot she can reach. Our hands clasp strongly for instant and I save her from fall.

Slowly, we release.

Next stop, she rushes out. But — just before the doors bang shut, she turns — looks straight into my eyes. “Kohn-bahn-wah” she says (“Good Evening”).

Thus, Japanese beauty touches beyond body into very soul of clumsy Westerner.

Fraught Framing: The Presumed Being-ness of State-ness

Fraught Framing: The Presumed Being-ness of State-ness

OLYMPUS DIGITAL CAMERA

As I understand it, in Spanish and Portuguese, for example, there is a linguistic distinction between current state of being and habitual state of being that is signaled by the use of different verbs. In English, we say, “That is an angry dog” to mean “That is a dog who is generally and habitually angry” and also to mean, “That dog is in an angry mood right now.”

But, regardless of what native languages we write and speak, we humans often make statements about something and treat something according to the unstated and untenable presupposition that what is true about the current state of affairs is true about eternity.

This habit of mind, reinforced by language, is often incredibly useful. For instance, near me right now are a table, and on the table, among other things are a coffee cup filled with coffee and a checkbook. The table is mainly composed of wood and marble. For many purposes, this is an adequate description. Of course, none of these so-called objects were always in their current state. Once, the wood was part of a tree. And, before that, the material in the tree was mainly rainwater and dirt. It was transformed into a tree by a mere seed of information using energy from the sun.

Meanwhile, even the marble portion of the table was not always in its current state. At one point, in the distant past, this marble was limestone. The limestone was transformed by temperature and pressure into marble. Before the limestone was limestone it was mainly the shells of tiny animals living in the ocean. If we trace the table back far enough we will come to the “Big Bang” that started the universe as we know it. The transformation of the table from one sort of thing into another did not end when it became a table nor when I bought the table. Some day, it will no longer be a table. Eventually, the material nature of the wood, and eventually even the marble will be different. The checkbook and the coffee cup will likely cease to be a checkbook and a coffee cup long before that.

For the purpose of drinking my coffee, it is just fine to think of this cup as being a cup. It holds my coffee and keeps it somewhat warm. The table works just fine as a place to hold the coffee cup. I don’t need to think more deeply about the lifecycle of the table or the cup or the checkbook.

Usually.

But sometimes, it is useful to deconstruct these categories. A fairly common test of creativity, for example, is to think of alternative uses. What could this table be used for besides a table? It is a pretty sturdy looking table, so I would say it could be used as a seat by one or two people pretty safely. It could be used as a deadly if awkward weapon. The bracing cross-piece could be detached and used as less awkward weapon. It could be used as a barrier. The wood part could be used as firewood. The thing that I habitually use as a coffee cup could be used as a container for many types of liquids or solids and even, with the help of the checkbook, could be used to hold gasses though not very effectively. The checkbook can be used as a weapon against a mosquito. In a very different way, the checkbook could be used as a weapon against a person or even as a weapon against a nation; e.g., by writing checks to steal an election.

While all of these “objects” have histories, they also have futures. Generally speaking, the people I know give little thought to the future of the objects that they interact with. But slowly, and likely too slowly, this is gradually changing. We often now recycle or reuse objects. Thinking about the future of an object also influences my choices about what I buy. This kind of thinking is particularly important to when it comes to radioactive material which can pose very long term hazards or it can be stolen and used to cause fairly short term mayhem. Collectively, the plastic that we use gets discarded and then, does not vanish into nothingness. It finds its way into the air we breathe and the water we drink. Now that the population of the earth is 7 billion, we can no longer afford to ignore how the objects we interact with were created and we cannot afford to ignore what becomes of them. What we call a “table” or a “cup” or a “checkbook” is really only a “table for now”, “a cup for now” and a “checkbook for now.”

The fluidity of things also applies to human beings. It should be pretty obvious to most adults that someone we call “a toddler” or a “teen-ager” is not in that category forever. Most people evolve over time both physically and mentally. The change from “toddler” to “teen-ager” takes many years. Physically, the person usually seems stable from one hour to the next (even physical stability is an illusion; we create over 200 billion new cells a day!). Socially and psychologically, however, we are unstable even at a macro level. A sixteen year old, for instance, may act very much like a mature adult in hundreds of different circumstances. Yet, if they are overly influenced by “friends” or under the influence of alcohol for the first time, their behavioral self-control may easily revert to that more like a ten year old or even a two year old.

We Limit Others by our Categories

It is human and common but not useful to observe a small slice of someone else’s behavior and thereby make inferences about their habitual behavior. Even if we know about someone’s habitual behavior, it doesn’t mean that they always behave that way and it doesn’t mean that they can’t change over time. When we say, “Oh, don’t pick Chuck for the baseball team; he’s such a spaz” or “No, I’m sure Sally wouldn’t like to join us; she’s really a loner” or “You can’t count on Jim; he never follows through” we are almost certainly over-generalizing. Perhaps Chuck never learned baseball as a kid and he simply needs to learn and practice basic skills. Maybe Sally has no real friends precisely because no-one asks her to join them because everyone thinks she’s a loner because she’s always alone – because no-one ever asks her to join them. Or maybe her idea of a good time is hiking and she’d be happy to do that, but has no interest in going clubbing and getting drunk every day. Maybe Jim is completely overworked and/or needs to learn better time management skills.

“How many psychologists does it take to change a light bulb? Only one, but the light bulb has to want to change.”

People may be changed by circumstances but therapy often works too. As the joke implies, it won’t work very well if the main reason the “light bulb” goes to the therapist is to feel better rather than to get better, it’s an opportunity lost. Others who frequently interact with the “light bulb” often hold views and use names that subvert therapy. For example, a person who is never assertive and wants to change that may find that when they do so, their family and colleagues at work, who have been taking advantage of them for their own purposes may say things like this: “Oh, you used to be so nice!” {Translation: I used to be able to manipulate you for my own purposes so much more easily}.

We Limit Ourselves by our Categories

While we unwittingly define others into boxes that may serve to limit what they can do, we humans are generally “equal opportunity destroyers” and also limit our own potential through self-talk as well. I like to play golf and have therefore asked many people over the course of my life, “Do you play golf?”

Take a guess what response I have heard at least two dozen times. “Golf? Oh, no. I tried that a couple times. I’m no good.”

After picking myself up off the floor, I try to explain as nicely and politely as possible that if you’ve literally tried it a couple times, you have no idea whether you would be any good at it. You very likely have no idea whether you would like it either. The same goes for painting, writing poetry, playing video games, eating healthy food, exercising regularly, and so on. In each case, your initial level of skill and your initial level of enjoyment are very poor predictors of the long term. It is most often, not our ability, but our self-definitional boundaries and self-talk that limits us.

Exercises for Flexibility.

Life is complicated and complex so I understand that many folks may be reluctant to expand the scope of what they and others are capable of. But if you do want to become more flexible in your behavioral repertoire, there are several things you can do.

First, you can become aware of your statements about yourself and others. When you find yourself thinking, “Jim never follows through,” try to restate that in terms of empirical evidence. It could be: “Well, once I asked Jim to help plan the office party and he never showed up for the first meeting. Another time, he said he would help teach my daughter how to parallel park, but nothing ever came of it.” You might immediately see that you have precious little evidence to back up your claim that Jim never follows through. You might also ask yourself whether you ever asked Jim about these incidents. There may be hundreds of legitimate reasons that he didn’t “follow through.” His name might have been left off the distribution list for the party planning meeting. And so on. Generating these alternatives is explored in more detail in “The Iroquois Rule of Six” which basically says before acting on an explanation that is inferred you should generate five alternative explanations.

Second, you can read fiction, watch movies, attend stage plays, do some amateur theater or even answer a questionnaire from someone else’s perspective. In working with Heather Desurvire at NYNEX, on a usability evaluation of a prototype, we did a variation on heuristic evaluation in which we had people look for issues and offer suggestions from a variety of different perspectives; e.g., a behaviorist, a cognitive psychologist, a worried mother, a physical therapist and so on. With the total amount of time controlled for, people found more issues and offered more suggestions when they looked at the application from the perspectives of many people.

Third, and my current favorite, is “Attitude Dancing.” I’m not sure this is what Carly Simon and Jacob Brackman meant by their song title, but when I turn on music while I am cooking or cleaning, I spent part of my dancing time dancing as though I were in a completely different mood or even as though I were a completely different person.

Give it a try!

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….

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.

Theory of Mind.

“Theory of Mind” refers to the ability of most humans to imagine, at least to a degree, what another person is likely to do based on their knowledge of what the other person knows. Here is a simple test used to determine whether someone has this ability.

You are the “subject” being tested and you are in a room with me (the “experimenter”). Your friend Vlad is in the room too. In full view of you and Vlad, I hide a giant luscious chocolate chip cookie (such as you might purchase from Panera, but won’t because you realize that if you buy it there is no way you aren’t going to eat it!). I “hide” this cookie in the top drawer of my desk. Now, Vlad walks out of the room. He’s well out of sight. Now, I take the cookie out of my drawer, and using great self-control, do not eat the cookie myself but instead put it in my pocket.

Now, I turn to you and ask, “When Vlad comes back, where will he look for the cookie?” If you are 2, 3, or 4 years old, you would say, “In your pocket!” I rephrase this a few times to make sure you understand that I am not asking you where the cookie actually is but where Vlad will search. You again insist that Vlad will look in my pocket. At such a young age, kids do not distinguish their state of knowledge from someone else’s. Most adults will have no problem with this task. They have a “theory of mind” that allows them to know that their state of knowledge is not the same as Vlad’s. Some adults diagnosed with autism will have trouble with this task however.

An interesting question arises as to whether other animals have a “theory of mind.” It is not a settled question. My purpose here however, is to explain what the term means and show how it’s useful for humans. Despite the fact that most adult humans have the capacity to do “theory of mind” tasks and that it is useful, they nonetheless often fail to evoke their capacity.

A closely related concept is “empathy.” Empathy generally refers to being able to feel what another person feels emotionally. I see the distinction as one of perspective or emphasis rather than two different entities. These two concepts (empathy and Theory of Mind) are explored in much greater detail in the “Myths of the Veritas” series in this blog. For now, suffice it to say that you might empathize with another person by relating to their facial expressions, posture, or regarding what they say and how they say it. You might see a picture of a small, terrified four-year old alone in a cage and know that they are terrified without having any verified knowledge or detailed knowledge of what they “know” or “don’t know.” They might or might not know any English. And you might or might not know their language or even what their language is. But you can tell that they are in great distress just by looking at them. If you actually feel what it is like to be a small child separated from your parents and being trapped in a cage in a strange place, that is generally called “empathy.”

If I were to ask you what kind of pleading this four year old is likely to make in court, if you have the capacity for a “Theory of Mind,” you might well ask, “Well…I don’t know. What do they know about courts or proceedings? What could they know? They are only four years old.” You’d be correct, of course, to question whether it was meaningful to have a four year old acting for themselves in court. This would be particularly true if they had to plead in a court where they were unfamiliar with the culture, the venue, and the language. But even a really smart four year old who had been brought up in America and spoke excellent English would not be capable of really understanding the consequences. This kind of understanding demonstrates a deeper theory of mind than simply knowing that because a specific piece of information is in your own head doesn’t mean it’s in someone else’s head.

In The Myths of the Veritas, people are given a range of tasks that involve what is called empathy. To me, although one can draw a conceptual distinction between understanding another person’s knowledge and feeling an echo of another person’s feelings, when it comes to many practical situations, it’s more important to put oneself in another person’s shoes, than to correctly label the process.

Writers must often deal with multi-level theories of mind. There is what the writer knows about the events that are being written about in a story. There are the spheres of knowledge that various characters have. Most often, different characters have critically different states of knowledge. What the reader knows is yet again different. And all of these spheres of knowledge change throughout the course of the narrative.

In The Myths of the Veritas, for example, the author knows throughout that ALT-R is making POND MUD put his face in the mud purely to humiliate him and keep power over him. ALT-R knows it as well. Over time, most readers will come to the same conclusion but not necessarily at exactly the same place in the narrative. Most of the Veritas tribe initially know nothing about this incident, but She-Of-Many-Paths intuits it and eventually many of the Veritas come to understand it. At first POND MUD is fairly certain ALT-R saved his life by making him do it. But as he observes and interacts with ALT-R and others, he begins to doubt that and then goes about actively seeking information from others that would help clarify ALT-R’s true motives.

In Othello, the writer knows from the beginning that Iago is an evil sociopath. The audience knows quite early that Iago is an evil sociopath and learns more about his schemes through speeches that Iago delivers directly to the audience. Othello himself, on the other hand, has his state of “knowledge” manipulated by Iago. The audience knows that Othello is being duped by Iago but Othello himself does not know of it or of Desdemona’s innocence when he murders her though at that point, the writer, the audience, Desdemona, Iago, Cassio and other characters all know that Desdemona is innocent. We have some sympathy for Othello because we realize that he is operating on false information.

Let’s turn to a happier piece of fiction, The Gift of the Magi by O’Henry (William Sydney Porter). In this story, a couple with financial struggles each gives up their most prized possession to buy a gift for the other. The functional value of the gifts is destroyed by what they gave up. Della knows that Jim’s most prized possession is his gold watch so she sells her beautiful hair to get money to buy him a watch chain. Jim knows that Della’s most prized possession is her beautiful hair so he sells his watch in order to buy her some jeweled combs for her hair. Of course, the real gifts they give are not diminished by their being no longer functional. The real gift is the gift of love. The author obviously knows all this from the beginning. Readers “catch on” to what is happening at various points in the narrative, but Jim and Della are the last to learn of the full irony.

Sadly, many people seem not to bother trying to understand the situation and capabilities of others. In one of the simplest cases, people are apparently unable to understand how very basic physical properties of the universe result in various people having various states of knowledge. On the tennis court, in a “friendly game,” the players themselves make the calls and keep track of the score. The server is supposed to announce the score before every serve. Some people actually “announce” the score by saying it so softly that only they can hear it!

In other cases, novice drivers will follow a semi truck so closely that the truck drive cannot see the car behind them. Another trick of drivers is to turn their blinkers on – but only as they begin making the turn. In another post, I explain how one person’s driving behavior in “stop and go traffic” can influence many other people’s. In particular, if you leave a large space between your car and the one in front of you, it makes it easier for many people around you to drive more smoothly because they have a much more complete view of what is happening in front of them.

A more subtle failure in “Theory of Mind” occurs when a person assumes that everyone is motivated in the same way that they are. For example, a person may be so partisan that they will always defend and promote people in their own political party no matter how heinous the crimes of that person. This is an error, but a concomitant error is that such people assume everyone who doesn’t defend the criminal, and certainly anyone who actively resists such a crooked politician is doing so from a purely partisan perspective because that’s what they would do. Sociopaths who cheat may assume that everyone would cheat and the only reason they don’t cheat is because those non-cheaters are not smart enough to get away with it.

When teamwork is operating at a high level, whether it’s hockey, soccer, tennis doubles, basketball, families, or design teams, people exhibit excellent “Theory of Mind” skills. How are yours? Have you experienced such high functioning teams? How can you improve your skills at “Theory of Mind”?

Meta-Cognition

“Cognition” refers to thinking activities such as problem solving, learning, decision making, and imagining. “Meta-Cognition” refers to thinking about thinking. The science of psychology, over the last 150 years, has learned a lot about human thinking. If you are reading this blog post, the chances are pretty good that you are a human being. Although there are important individual differences in how people solve problems, learn, make decisions, and use their imaginations, there are also huge similarities. To the extent that you understand your own thinking, you can use that knowledge to do a better job of problem solving, learning, decision making and using your imagination.

Here are a few examples that you may already be aware of. I really like chocolate. And I really like almonds. Chocolate-covered almonds are one of my very favorite foods. I know this about myself. I also know that I am easily distracted. I’m not the sort of person who begins to write a blog post, thinks about chocolate almonds and then stops writing to rush out to the store and buy a package. In fact, there is almost no activity that I can be engaged in which I would interrupt in order to go buy chocolate almonds no matter how much I craved them. On the other hand, if there were a bowl of chocolate almonds right beside me, in easy reach, I would definitely reach over and grab some whenever I paused in my writing. So, how do I use the knowledge about my own behavior to control my own behavior?

I don’t often buy chocolate almonds. It’s very easy to simply not go to the part of the grocery store where these little devils hang out. If I walk by, I know that they will start singing to me like the Lorelei of legend: “Come get me! I am so tasty. Get me now. Please. I want to go home with you.” But I can’t really hear them that well beyond about five feet. Probably this is because they have a very rudimentary vocal apparatus.

I do buy them perhaps once a month and when I do buy them I put them in a closed drawer so they are mainly out of earshot. Then, I will have a few and get back to work. I may not have them for days at a time. If, however, I put them in a bowl right beside my computer, I am fairly certain that I would eat the whole box the first day; indeed, quite possibly in the first hour.

This is an example of using what I know about how I think about things to think about arranging the environment to my own long-term benefit.

Another example, which I may describe in more detail later, is the so-called “Primacy Effect.” This is known in popular terms as the power of “First Impressions.” If your first experience with something — whether it’s dogs, cats, Chinese food, or computer programming — is negative, it will be difficult to overcome that later. This is not only true of emotional reactions. It’s also true about what you recall about something.

Suppose that you meet someone named Joseph Josephson at a party and John has a beard and long black hair. Perhaps you talk to Joseph for ten minutes. You meet Joseph a few months later at a tennis match and now he is clean shaven and has short hair. You play tennis with him for an hour. A few months later, someone happens to ask you if you know Joseph Josephson. Chances are, an image will pop into your head of Joseph with long black hair and a beard. Of course, sales people, politicians and wise people applying for jobs make use of this and want to make a “good first impression.” Since you now know that first impressions are particularly important, you can use this knowledge about how people think to make sure that first impression is a good one.

You can also use that knowledge to help modify your own thinking and decision making. Suppose someone comes to you for a job interview and the first thing they do when they walk in your office is trip over a chair and spill their papers on the floor. That’s unfortunate! It is quite natural to immediately conclude that they are unsuited for the job. At this point, you could remind yourself though that this is only a first impression and that you should not let it color your judgement about whether they are the best candidate for the job. You probably won’t be entirely successful in not letting it cloud your judgement, but you will be somewhat successful.

As I explain in The Winning Weekend Warrior, you can also use the “Primacy Effect” in sports. For example, if you are serving in tennis doubles, if you mainly want to hit a flat serve and stay back after serving, you might serve a kick-serve and follow it to the net a few times at the beginning. Even if you never do this again, your opponents will continue to be “looking for” that kick serve and may prepare their return on that basis.

When it comes to evaluating candidates for jobs, you must also be wary of the “Halo Effect.” If you find out something good about a candidate, it will tend to cloud your judgement about other aspects of their qualifications, even if that “good thing” is likely irrelevant to the job. A physically attractive candidate will tend to be judged as more qualified overall even if the job has nothing to do with physical attractiveness. But now that you know this about human judgements (and therefore also your judgements), you can take steps to minimize the “Halo Effect.” It may help, for instance, if you specifically judge candidates on several dimensions of background or experience. The more “objective” you can make the criteria, the less susceptible the judgments are to the “Halo Effect.” So, if the candidate is very attractive, for example, if you simply say whether they are suitable for the job, there will be a relatively large impact of their attractiveness. On the other hand, if you are asked to separately rate the candidate on Work Experience, Educational Background, Appearance, and Relevant Skills, the Halo Effect from their physical appearance will tend to be mainly (but not wholly) focused on the “Appearance” factor. If you answer even more specific and objective questions such as: “Does the candidate have an advanced degree?” or “Does the candidate have more than two years programming in C?” the “Halo Effect” is further minimized.

One of the most common ways that people use meta-cognition is simply to write things down. You and I both know that we have a tendency to forget. Most of us, therefore have paper or electronic calendars. We don’t typically rely on our own memory to keep track of a complex schedule of appointments. Why? Presumably, we do this because we know that we are likely to forget an appointment if we rely on our brains. Most of us do not bother to put our own birthday on the calendar because we realize that we are quite aware of it and not likely to forget. People who celebrate Christmas often do not bother to put that date on the calendar either. We know that it would be rather hard to forget! Similarly, many people who go grocery shopping and buy milk, eggs, and bread every week do not bother to put it on the list. If your aunt Mary is coming to visit and she requires soy milk, you probably will put that on your shopping list. You realize (through meta-cognition) that this is an item you are likely to forget.

These are just a few examples. Findings about human cognition abound. You can use these findings to do a better job in your own thinking; you can use those same findings to help you in competitive situations in predicting what others will do. If you are interested in more such findings about psychology, you might find these fascinating and well-written books of interest.

Many Paths

Many Paths

{Translator’s Note}: Exciting news: more (mythological) archaeological evidence is being unearthed as I write this about the mythical Veritas tribes. My next series of translations will be put on hold however, until we have a chance to arrange and understand this new evidence so that I may use it to help guide the translations. In the meantime, I’ve asked one of my psychologist friends (Dr. John C. Thomas) to take over the blog for awhile and write short posts on such topics as thinking, problem solving, and creativity. Dr. Thomas has been studying these topics for fifty years. He was also trained as a Fellow in Rational Emotive Therapy. He has over 300 publications and presentations on psychology, AI, human-computer interaction, and user experience.

Hi, folks. I imagine many of you, like me, can hardly wait to see what these new findings will be regarding the Veritas tribe. Meanwhile, I’ve been asked to fill in by helping us think about thinking. One of the main characters we’ve been following in the myths of the Veritas is “She-of-Many-Paths.” She personifies the first thinking skill I’d like to discuss.

This skill goes by many names including “Alternatives Thinking,” and “Divergent Thinking.” It is also discussed in the Pattern: “The Iroquois Rule of Six.” The basic idea is simple. When we are confronted with a situation, we often “Jump to Conclusions” or “Spring into Action” before we have all the facts. Even when we have all the facts (which is rare), we also have a tendency to focus on our first interpretation. This often leads to thinking of one (and only one) course of action. And, very occasionally; for instance, in some emergencies, that is the correct thing to do.

Even in emergencies however, our first terrified instinct about what to do can be dead wrong. For example, people see a small fire in their homes and immediately throw water on it. But if it’s a grease fire or an electrical fire, this is not a good course of action. Soon after I first began my dozen years as Executive Director of the NYNEX AI Lab, there was a fire in a nearby Stouffer’s Hotel. The charred bodies of a dozen IBM executives were found huddled in a closet. In the smoke and panic and confusion of the fire, they had apparently grabbed at the first door and gone into a dead end closet and perished there.

In daily life, there are a great many situations where a little extra thinking time would improve the outcome. For example, while working at IBM Research in the 1970’s, I drove about 10 minutes each way to work. At one point, I had a loose fan belt and my battery went dead. In a hurry to attend a meeting, I jump-started my car and drove to the IBM parking lot. Already late to a meeting, I went to turn off the car and just before I did so, I realized that I had not driven far enough to recharge the battery. So, I decided I’d better leave the car engine running for awhile. But as I gathered up my things and began dashing off to the meeting, I realized that it was insane to leave my car unlocked with the engine running! After all, someone could simply open the door and drive off! So, still in a hurry, I locked the car — with the engine running and the keys safely locked inside.

Most of us have done similar things. In some early experiments on design problem solving done at IBM, I found that when I asked people to come up with as many solutions as possible, they would generate ideas fairly quickly until they came up with one that they thought would really solve the problem. At that point, their idea productivity fell precipitously. It is hard for us to force ourselves to think of more than one good solution.

Why is this important? For one thing, conditions change. Something may happen that makes your first solution no longer apt. For another thing, there may be side-effects of your solution that make it unacceptable. Another class of problems is that someone may object to your first solution for reasons you could not foresee. (See also, “Who Speaks for Wolf” as a way to help minimize that chance). In the context of invention and product development it is extremely unlikely that the first solution you come upon (and indeed even the first few solutions you think of) are novel. They are instead extremely likely to be the intellectual property of someone else. The most obvious solutions have likely already been patented and may already be in products or services that many customers are already using.

I have long been interested in observing people’s strategies and tactics in sporting events (See “The Winning Weekend Warrior”). One tactic that is overwhelmingly popular in tennis, for instance, is that the harder your opponent hits the ball, the harder you try to hit the ball. For example, someone hits a very hard ball while you’re at the net. You take this as an affront and think “I’ll show you!” Trying to hit the volley even harder means you take the racquet back farther. About half the time, the extra time it takes to bring the racquet back means you’ll mis-hit the ball or miss it entirely. On most of the remaining occasions, you’ll hit the volley too hard and it will go long. If someone hits the ball at you hard, what you need to do is simply block it back and guide it to the right spot. Trying to add extra power is unnecessary and too time-consuming. What is remarkable is not that you and I try to hit a hard ball harder. What is remarkable is that we never seem to try a different tactic!

There are many issues with focusing all your energy on the first solution you come up with. But the worst consequence is that you are overly invested in that first “solution” (which may not even be a real solution). This is bad in trying to solve problems in every domain I can think of and having others involved amplifies the badness.

For instance, let’s say that after 3 years without a vacation, you and your spouse finally have time for a nice two-week vacation. You want to visit Cuba for two weeks and they want to visit Vietnam for two weeks. If you each only come up with one idea, you will almost always find yourself pitching for your idea, trying to convince the other person that Cuba is better while they will spend their energy trying to shoot down your choice and explain (patiently at first and less so as time goes on) why Vietnam is a much better idea. After many frustrating arguments that go nowhere, you may decide to compromise; e.g., you could visit an empty stretch of open sea in the Pacific Ocean half-way between the locations; or, you may decide to flip a coin. All this frustration and bad feeling might be avoidable. It could turn out that your second choice and your spouse’s second choice are both San Diego! But you’ll never even discover this because when each of you only thinks of one idea, what should be a collaborative problem solving exercise instead becomes a debate – a contest with precisely one winner and one loser.

Thinking of many alternatives will save you many headaches – at work, in your love life, in your recreational endeavors. When you force yourself to think of many alternatives, you will also be more open to the ideas of others. Over time, thinking of many alternatives whenever you get a chance will also increase your own creative potential. Who knows? You might even be chosen as the next leader.

For a leader, it is particularly important to consider many possibilities. Insisting that everyone get on board with the first idea that pops into your head will cause resentment and dissension. It will also make you far less willing to change to a different idea when circumstances necessitate it.

You may start a business and decide that you must be personally involved in every decision and with every customer contact. At first, when your company is small, this might work out wonderfully well. No-one knows the customer and the product quite so well as you do. But you are not God. You cannot be everywhere and know everything. If you never learn to delegate; never grow the capacity of your people; never take expert advice — you will drive yourself and everyone around you crazy. The very success of your business will guarantee its ultimate failure. Learn to consider many paths. You will be glad you did.
