Shadow Walker took the first watch along with Easy Tears. After their long day’s march, it would be too easy for a single sentry to fall asleep. Shadow Walker felt as though, for him, it was an unnecessary precaution but he realized that could be a delusion. He might be more prone to sleep than he realized. Easy Tears and Shadow Walker had known each other since childhood and they were comfortable with each other. The wolf pups lay beside them and helped stave off the chill of the night air. Though the pups appeared to be in a deep sleep, he suspected they would be awake in a flash if more ambushers tried to sneak up on their search party.

Quietly, Shadow Walker began to chat with Easy Tears, the better to keep them both awake. “We should watch out for snakes as well. They are drawn to body heat as well as the fire. I suspect this is the sort of place that many rattlesnakes may make their home.”

Easy Tears responded, “I am not so much a friend to the snakes as you are. They aren’t always so easy to see either. I recall once almost stepping on a large snake who had a rattle-tail of ten rattles.”

Shadow Walker considered this, allowing the silence to flow between them. “Those snakes can fool the eyes. That is true. A walking stick, a butterfly with the eyes of an owl. Many animals make themselves look or sound like something else…or just fade into the background.”

A shooting star streaked across the sky. Shadow Walker had jerked his finger to share with Easy Tears and though she turned quickly, she only caught a brief glance. “Like those whom we pursue. They don’t hide their trail well at all. But then they simply disappear!”

Shadow Walker considered this. “You’re right. I suspect that once we search in daylight we will find some sign of continuing trail. I’m impatient to continue but we need the rest and … the sunlight will show us the way.” Shadow Walker noticed that the soft glow of the firelight flickered on the eyes and hair of Easy Tears in a most pleasing way. Shadow Walker thought of Many Paths and the serious conversation that they had postponed.

Easy Tears shivered slightly. Shadow Walker considered sidling up to her and putting his arm around her so that they would both enjoy the warmth of the other. It would be all right. Pleasurable even. But sometimes, it is difficult to know what is around the next bend and the one after that. Instead, he stood and got another blanket and draped it around her shoulders, then added another log onto the fire. He sat back down and reflected on his discovery that snakes could sense the heat of their prey. If only they could train a snake to be a helper. That could prove useful. He wondered aloud, “Easy Tears, if people can train horses and wolves and eagles, do you think it is possible to train snakes?”

Easy Tears chuckled slightly. “I wouldn’t think so, but you are the expert. I don’t really care for them, though I do appreciate their eating the rats and mice that try to steal our grain.” She considered for a time. “I suppose you could train them. Yes. I suspect you could train anything with enough love and patience. But you see how it is. Despite your love and patience, there is always a chance they would bite you or misunderstand your intention. I suppose it might be something that would take a long time. What would you train a snake to do?”

“I wish we could have their sense of heat. Perhaps we could use them to follow trails or find hidden enemies. Maybe we could even train them as guards. Ours did not work so well for some reason. That bothers me. How could such as these who do not cover their tracks elude our guards?”

“I don’t know. Perhaps they did not try to elude our guards at all, but simply overpowered them too quickly for them to sound the alarm. Or perhaps, they feigned being peaceful? Trunk of Tree will figure it out. I like him.” She smiled and glanced at Shadow Walker. “Do you think he likes me?”

Shadow Walker considered this. Trunk of Tree had never said anything, but judging from the actions and looks of Trunk of Tree, probably so. “Yes, I think so. He looks at you…with longing. You are a beautiful woman, after all.”

Easy Tears smiled and Shadow Walker realized that he really found her attractive, but not in the deep way that he loved Many Paths. The half moon set and it grew darker. “It’s time to wake the next guards. He calmed his mind and thought of their serious quest in order to cool his blood. Then, he stood and walked over to Lion Slayer. He stood almost on top of Lion Slayer but Lion Slayer appeared to be a sound sleeper. He snored loudly and Shadow Walker joked, “I wonder whether he actually slew the lion with a spear…or with that snore.”

Easy Tears laughed aloud but all the others remained asleep. Shadow Walker squatted down on his haunches and shook Lion Slayer. The snoring continued. For a moment, he considered shaking Hudah Salah but decided against it. He shook Lion Slayer again and whispered his name. Hudah Salah suddenly sprang to his feet and pressed his thumbs against Shadow Walker’s windpipe. Shadow Walker smacked the hands away and jumped back, “Lion Slayer! It’s all right. It’s me. Time for your watch, as agreed.”

Lion Slayer shook his head. He looked hard at Shadow Walker and mumbled something unintelligible. At last, he seemed to come to his senses. “Yes,” he said and awakened his wife.

Easy Tears lay down and smiled at Shadow Walker. She moved her body so that sufficient space appeared next to her for the body of Shadow Walker to fit snugly. Shadow Walker sighed and lay down instead by himself and dreamt of Many Paths.

The next thing Shadow Walker sensed was light. It was not yet dawn. The troop all awoke and had a small breakfast and then began exploring the cliffs for a sign or a path. As they explored, they continued to chew pemmican and some dried fruit. Shadow Walker had asked Fleet of Foot to explore with Easy Tears, who took the wolf pups with her. Shadow Walker walked with Eagle Eyes. It was understood now by the group that Lion Slayer and Hudah Salah were fairly inseparable.

Although Eagle Eyes had the best vision, Shadow Walker’s eyes were also sharp but he found nothing but sheer cliffs. Eagle Eyes said, “Wait.”

“What do you see?” asked Shadow Walker.

“Nothing really. But something’s not right. It does not look right here. I’m not sure why.” Eagle Eyes stood with her hands on her hips staring at the sheer cliff face. She looked up the cliff face and noted various hand holds. “This wall might be scalable to a good climber.”

“Yes, I can see that as well though it would be dangerous. But horses? They are horses, not mountain goats” Shadow Walker said without blame or sarcasm.

“I know, but still, something is not right.” Eyes of Eagle shook her head and asked herself what she was missing.

Because the pair had stopped their systematic exploring, the rest of the search party converged on them. Fleet of Foot was the first to arrive. “Did you find something?”

Eagle Eyes smiled at him. “Not really. But his does not look right.”

Easy Tears arrived next with the wolf pups who immediately began jumping and whining. They sniffed around the base of the rocks and ran back and forth between the rocks and Easy Tears. They had clearly caught a scent of something. “Perhaps Tu-Swift?” suggested Shadow Walker.

The pups took turns trying to stick their nose into a small cleft in the rock. On impulse, Shadow Walker, put his fingers in the cleft and tried pulling. He could not budge the rock, which did not surprise him. But the feel of the rock did surprise him. It was much like flint but harder and colder. Beyond that, there was no texture to the rock. It felt, somehow, dead, even more dead than the bleached bones of a long dead buffalo. Shadow Walker lay on his back and tried to push on the cleft with his feet. Soon, all six of them pushed and pulled on the rock face though they had no hope of moving it.

And then, it did move, though very slightly. The group positioned themselves and pushed even harder. The rock slid more easily now like a smooth stick along the winter lake ice. Instead of the grinding sound of rock on rock, however, they heard an unearthly screeching sound like a very large eagle.

At last, a huge slab of the cold rock had been moved aside and behind it, all could see a large, short passageway into a sunlit path beyond. The wolf pups bounded through and out into the sunlight. The people followed. Eagle Eyes looked back at the strange rock and noticed something stranger yet. The back of the rock had many handles. She supposed they were to replace the rock. But at the bottom of the rock, she saw something that made her gasp aloud.

“What is this?” she asked. All of them turned and looked at the base of the weird rock. There were circles of rock on the bottom! What strange magic was this? Despite their hurry to find Tu-Swift and their excitement at finding the way out of the box canyon, each knelt down to marvel at the smooth circles of rock.

After some time, Shadow Walker said. “We cannot solve the mystery of this rock. We must follow the trail. Should we close this … door? If we do not, it may be apparent to any of the Stands on Horses people that we are coming for Tu-Swift. But when we return, we may be in a hurry to go through this way.”

Eagle Eyes spoke next. “We could leave it just slightly open so that we could squeeze through but no horses could. I think we could make this door, as you call it, harder yet to open or close.”

Fleet of Foot spoke. “We should hurry up and get to Tu-Swift as quickly as possible. We have no idea how badly hurt he may be.”

Shadow Walker: “We cannot know for certain the best course of action. I think it best to put it back the way it was. We are not going to be able to overwhelm our enemy with force. We must rely on secrecy. We may or may not be able to save Tu-Swift. But others of those who stand on horses find out we are on the way to their camp, they may go more swiftly and warn their people. That will make rescue impossible and even reconnaissance riskier. Let us move this back and follow the trail. We may also find another way back that is less familiar to those who ride on horses.”

I proved difficult to move the rock back, but they succeeded and they then resumed their tracking, which was again an easy task. Perhaps, thought Shadow Walker, those who stood on horses felt they were so fast they would not be pursued. Or, perhaps, they had not learned to hide their trail. Or, perhaps they thought that odd rock door would cut short any pursuit. Eagle Eyes with Easy Tears led the team with the pups trotting along side them. Next came the pair from the Nomads of the South. Shadow Walker and Fleet of Foot carried the heaviest loads and kept looking for and erasing signs of their trail. They stayed within the confines of the large swaths of changed lands that the galloping horses provided. This made “covering” their trail fairly easy. Trackers of the Veritas might wonder at the paw prints of two wolf cubs traveling without a pack, but Shadow Walker felt it likely that these would not raise suspicions among those he was tracking since they seemed so unconcerned about their own trail.

Shadow Walker was happy to concentrate on the trail ahead and to check to make sure there were no more of those who stand on horses behind them. In this way, he could avoid wondering about things that he could neither control nor prepare for. Many Paths was or was not okay with the rest of the Veritas. Tu-Swift was or was not okay. The only distraction that he really couldn’t block out was the smooth cold feel of the rock that was not rock and the circles of rock. There was also a very odd smell about that rock – something he had never smelled before, but it reminded him of death.

The Bonds of Horses and Humans

Tu-Swift awoke in pain. He began to panic. At first he wondered and quickly then became sure that they must have beaten him again. Inventory. “Don’t jump to conclusions.” That’s what Many Paths would have said. Inventory. He quickly realized nothing was broken. No, it was just that his muscles were sore. Although he spent a lot of time running, playing, and working among the Veritas, his ride on the back of a horse and then spending a day shoveling manure used his muscles in new ways. His body was okay. As he thought of the Veritas, however, his heart sank. Up to now, he had secretly thought that he would soon be rescued. Now a new and uglier thought crept into his soul. He took deep slow breaths and tried to calm himself. Day-Nah was beginning to stir and Tu-Swift didn’t want to alarm him by appearing scared. But the truth was, all the Veritas may be killed or enslaved. He might even be the only one to transmit their long collective years of wisdom accumulated.

Painting by Jeremy Colier

That was the cold, bitter spider of doubt that clutched his heart. Though he had no idea whether or not the Veritas had survived the attack, he had been assuming that they had been alive. But there were many other possibilities. Tu-Swift set his jaw. He had always been one to leap before looking while Many Paths kept reminding him to consider other alternatives. But now — Many Paths was not here. He would have to rely on the Many Paths in his head. And, others. There were other voices Among the Veritas who he could use to help him find a means for escape. Meanwhile, he must keep his spirits up by reminding himself of what he liked; what he was grateful for. Tu-Swift realized that, among other things, he was actually grateful to have this small boy as a companion. Worrying about his small jail mate distracted Tu-Swift from his own predicament and uncertainty.

Just then, Day-Nah stirred and whimpered. He suddenly sat up and yelled. Day-Nah’s eyes returned to that wild-eyed stare that Tu-Swift had first observed. Tu-Swift patted his own chest forcefully and said, “Tu-Swift! Tu-Swift!” Then, he gestured toward Day-Nah by opening his arms and hands outward toward the youngster and said, “Day-Nah. Day-Nah!” The young boy blinked several times and seemed to recall his present circumstances. His breathing slowed, but he pulled his legs up, wrapped his arms around his knees and began rocking and silently crying.

Like all of the youth of the Veritas, Tu-Swift knew how to comfort the young of his own tribe, but he felt uncertain about approaching the boy in this state. Though tempted to hug him, he decided distraction might be a wiser course and he reviewed the language lessons they had already gone through, being a little more particular about pronunciation, both in his attempts to mimic the sounds of Day-Nah and in Day-Nah’s repetition of of Veritas. This seemed to calm the boy and his silent tears abated. Once more Tu-Swift grew both angry and troubled that anyone would steal such a young boy from his family.

The horses were stirring as well, though it was early morning, judging from the gray light that crept into the horse enclosure. In the distance, Tu-Swift could hear many people stirring and getting ready for the day. Again, he had the distinct feeling that it was like and yet very unlike mornings among the Veritas. There were footsteps, and there were voices. The accent and cadence of the voices was different, but something more profound was different. He heard birds chirping, squawking, crowing, cooing and so on, but some note was missing. Tu-Swift thought of a rainbow and imagined what it would be like to see a rainbow that was missing the blue or the red. But no! This rainbow was missing all color. Why did it sound like a colorless rainbow? That made no sense. Tu-Swift shook his head. He wished he could have a real conversation with Day-Nah, but he knew of no way to try to communicate such subtlety.

Three large, burly men came into the large horse room. One of them put down two dishes of food and a flask of water. He grumbled something at them. Tu-Swift noted that none of these people seemed very interested in trying to teach them their language. The other two stood nearby and all three watched as the boys ate whereupon they were led out to an open pit toilet and from there to a large field fenced in with logs. There were a large number of free running horses in this particular field and among them, Tu-Swift could see five foals. Working together, the three large men managed to separate one of the foals from its mother. Tu-Swift could see that the mare stomped around dangerously, whinnied, and that the whole herd seemed agitated. Every horse in the herd, however, shrunk back, terrified of the men and eventually one man managed to tie a rope around the foal’s two back legs and another around the forelegs. Tu-Swift looked to his own legs and those of Day-Nah and saw that they were in much the same predicament. They, like the foal, could walk, but not run or jump.

Tu-Swift realized how much he loved to run free. He reveled in the feeling and he felt both sadness and anger at being prevented from running. He wondered whether he would ever be able to run free again. He begin to wonder whether he — or the foal — could ever be truly happy if they could not run free. Then, Tu-Swift thought of the snails that he had so often collected from the Veritas gardens. He had looked fairly closely at the creatures. They were fairly cute actually. Of course, as Many Paths would point out, he had no way to tell how a snail felt. But there was no reason to think they wouldn’t be happy. Finding something nice to chew on would probably make the snail happy just as it made him happy. But it was not in the nature of a snail to run. At imagining this, Tu-Swift laughed.

Day-Nah tilted his head with his brows pinched together as he regarded the older boy. Tu-Swift smiled at the boy and at his situation. How could he explain that he had been imagining a snail trying to run? Then, it suddenly hit Tu-Swift that the “color” that was missing from all the morning sound of these captor-people was laughter — not just laughter itself, but any kind of fun, or enjoyment. So far as he could tell, they did the same things that the Veritas did (except for tying up other creatures), but they didn’t seem to enjoy any of it! What a strange, gray life that must be, thought Tu-Swift. And he suddenly realized that he actually felt sorry for his captors! He imagined telling Many Paths.

Just then, all three men came over to them and shouted at the same time. Neither of the boys had even the slightest idea what they said and this must have been obvious to the three because they all switched to miming what the boys were to do. They were to do what the three grown men had just done! Somehow, they were to cull four more foals and tie their legs with rope! The Veritas had ropes, but Tu-Swift decided that it was a fair bet that Capture-People didn’t know that. The Veritas were all taught at an early age that those with more power seldom bother to learn even what would be of immense value to them if that knowledge lies with those out of power. The Capture-People had horses — and they had captured one, at least, of the Veritas. So, they would think themselves superior and be willing to believe any lack of intelligence or knowledge on the part of Tu-Swift.

He acted quite incapable with the ropes at first, only slowly catching on. Tu-Swift had no idea how the two of them were supposed to accomplish what looked very difficult even for three large men, three who did not have their legs tethered. Cautiously, they sidled into the pen staying near the exit that only they could squeeze through. Oh, thought Tu-Swift, Eagle Eyes will love to hear about that! Although tinged with sadness, he realized that he wasn’t really away from his own village at all! They all lived in his own head! As long as he lived, the Veritas lived!

Most of the herd headed to the far end as the boys entered, but one mare and her foal chanced nearing. The mare seemed to like their company! Perhaps she could see that they were tethered as they were. Tu-Swift gently tugged at Day-Nah by the arm and positioned him so that the men could not get a clear view of the mare. The mare smelled something nice on the rope between Tu-Swift’s legs. It began chewing on the rope. Tu-Swift admired the teeth and jaws of the horse before him. He spoke to the horse in Veritas though he was under no illusion that the horse would understand him, at least in any detail or words. “I am Tu-Swift. You are?”

At this point, the horse made a sound like “Kneeeeee -Kwah”

Tu-Swift continued, “‘eee-qua’ it is then.”

“Tu-Swift likes to run. Ee-qua like to run. We don’t like ropes. (Here he made a show of waving the ropes in the air so the three men would think they were making progress.) “We want to run free. Tu-Swift and Ee-qua run free one day. Yes, we will.”

Tu-Swift hobbled over to the foal and sat on the ground. “Hello little one. We have a predicament. I have these ropes on my legs. I don’t like them, but if we don’t wear them, they will beat us until we do. Your mother, Ee-qua chewed my ropes nearly through. So, I am going to put these ropes on you. But you will be able to run free in a few hours. I know you don’t understand a word I’m saying but maybe the sound of my voice will help you know that I am your friend regardless of how it seems.” Tu-Swift meanwhile, had succeeded in tying a rope around one of the young colt’s legs and “secured” it with a granny knot rather than the square not that the men had shown him. It was chancy to make life difficult for those that seemed to have power over him, but it had to be done; carefully, and never in the same way twice, but each day, Tu-Swift knew that he could find some way to make the lives of the Capture-People less pleasant, just as they were making his less pleasant.

Hiding tools, wrecking tools, backing up sewage, polluting water, passing on disease, poisoning — these were just a few of the ways he might or might not be able to fight back. Meanwhile though, he also had to be careful not to be caught and to have a well-worked out and plausible excuse. As Tu-Swift tied more legs with granny knots, he planned that he would feign astonishment and excitedly show his captors how he had tied the knots. He would tie granny knots. They would smack him about a bit of course. But then they would show him the correct way. He would again copy but make a granny knot. The Capture-People would smack him around a bit, so he imagined, and then show him again. He would feign insight and make a true square knot the next time. This would serve two purposes. It would cause them grief, but it would also, he hoped, endear him to them in some perverse way. It would be as though he could learn their tricks — eventually — but being more stupid than they are — it would take him longer naturally to learn to do things correctly. And, then again, he thought, fastening the fourth leg with a granny know, I may never even be accused.

Just then it occurred to Tu-Swift that the horses could chew threw their own tethers! Why hadn’t they thought of that. Maybe that’s not the sort of thing horses “think of.” Maybe they need to be shown. If they will eat through my ropes — and she could have easily gone all the way through — they could eat through their own, but how can I get food to put on those ropes?

Symmetry

{Something went wrong with WordPress the first two times I tried to post this. I tried to track it down. As best I can tell, my problems came from trying to cut and paste pictures from my Pages file. Even though it looked fine in the editing interface, it appeared blank in the actual viewing interface.}

Symmetry

(Original, free-hand drawing by Zoe Colier).

There are many varieties of symmetry. In many cases, symmetry exists rampantly in nature and symmetry is incorporated into many human designs as well. In this short essay, I want to remind people of several varieties of symmetry and then show how symmetry may also be used as a tool of thought to help solve problems by simplifying the space of possibilities that must be considered.

Symmetry is a concept with far broader application than cutting out paper snowflakes or choosing a nice looking Christmas Tree, Menorah or other Holiday decoration. It is fundamental in logic, mathematics, physics, chemistry, biology, and even in social science. Symmetry exists at many different scales as well. Planets are generally roughly spherical and their orbits are roughly circular.

The human body, along with most other animals, exhibits rough bilateral symmetry in external appearance. If you examine your own fingerprints or the pattern of your moles, for instance, you will see that one side of your body looks slightly different from a mirror image. If, like me, you are a righty who play tennis, you will find the forearm muscles on your right arm are slightly larger than those on the left. What is remarkable to me is not that there are slight variations between left and right but just how slight those variations are! And, we are not alone. Fish, insects, flatworms, roundworms, snakes, turtles, lizards, horses, dogs, cats, apes, and humans are all roughly bilaterally symmetrical in appearance. I say “in appearance” because our internal arrangement of organs is not at all symmetrical.

External Appearance and Internal Organs

In general, it seems to me that most animals possess more complete or “perfect” bilateral symmetry than do most plants. I suspect that this is because animals generally move through a physical environment. Since we can move around, the environmental forces are generally symmetrical and so our ability to react to those environmental forces is also symmetrical. A tree, on the other hand, may have a genetic “blueprint” to be bilaterally or (more likely) radially symmetrical, but it may be subject to strong asymmetrical forces such as wind, a water source, or sunlight versus shade.

Our designed objects are also most often (at least) bilaterally symmetrical, and particularly for those objects which must interact and move through the physical world. Cars, boats, motorcycles, busses, trains, trucks, bikes, skis, surfboards, roller skates, ice skates, snowshoes and tennis shoes all tend to be bilaterally symmetrical. On the inside, however, again just like us, there are often some irregularities. The arrangement of controls of the car, for instance, are asymmetrical. (Each control in itself often does show symmetry. In some cases, this makes it easier to use, especially without looking. I suspect that the symmetry may often be for aesthetic reasons, for ease of manufacturing, for ease of maintenance or replacement or some combination.) The asymmetry of arrangement “works” because the arrangement of displays and controls does not interact with the natural world the way that the car body and wheels do. The controls are designed to interact with a human being. There are also rough conventions for where controls are laid out, how they operate, and what each type looks like. Asymmetry of arrangement is also evident under the hood. However, some of the components such as the engine, the battery, the radiator have symmetry within them. The radiator, which arguably has the most interaction with the outside world, is symmetrically placed though its plumbing is not.

In the design of User Interaction and Experience, an argument can be made for certain kinds of symmetry. For example, in the Mac editor Pages, which I am using to write this, if the B for bold button background turns blue when bolding is turned on, I expect the background will turn back the way it was (white) when bolding is turned back off. I also expect that italics and underlining will behave the same way, especially because all three are in the same toolbar.

Where possible, it also generally makes sense, I believe, to design so that the functionality of a system is symmetrical. This isn’t always possible. Some actions are necessarily irreversible. If you don’t believe me, ask anyone who has toddlers or who has cats as pets. In the real world, if you shoot someone dead, you cannot “unshoot” them. Unlike a computer system who asks, “Do you really want to delete all your files?” before doing so, guns do not ask that. If you are designing what can be done with a toy robot however, if you can make it go forward, you want to make it so it can go back as well. If it can turn right 90 degrees, you would like to enable it to turn left 90 degrees. Saying, “Oh, yes, but don’t you see, you can, in effect, make it turn left 90 degrees by making it turn right 90 degrees three times?!” does not cut it, IMHO.

Typically, you not only want the functionality to be symmetrical, you also want the control functions and appearances to mirror the symmetry of the functionality. For example, if you can issue the command: “MOVE ROBOT FORWARD THREE PACES” you want the symmetrical function to be evoked this way: “MOVE ROBOT BACKWARD THREE PACES” and not, “THREE PACES BACKWARD FOR ROBOT MOVE.” If you decide to give auditory feedback for the first command that says, “ROBOT MOVING FORWARD THREE PACES” you do not want the reverse command to provide feedback that says, “ROBOT THREE PACES BACKWARD MOVING.” (Oh, by the way, if you cannot provide symmetrical functionality, please do not pretend to do so with a facade of symmetrical looking commands that actually behave asymmetrically!)

A lack of symmetry (or consistency) in the functionality, command structure, or visual appearance often arises because of a lack of communication within the development team. If different functions of the robot are to be implemented by different people, then it’s important that those various people use an agreed upon style guide or Pattern Language or that they communicate frequently. Of course, this is not the only cause of asymmetry. Even if your team communicates really well, they can’t design an effective gun with an “unkill” function.

There are, of course, various types of symmetry. Bilateral (mirror) symmetry is what the external appearance of our bodies has. There is also translational symmetry, where the same shape is repeated along a line. The string ABCCBA shows bilateral symmetry while ABCABC exhibits translational symmetry. Most human factors people now agree that hot water faucets (usually on the left) and cold water faucets (usually on the right) should both be turned off by turning to the right and turned on by turning to the left (translational symmetry) as opposed to having the faucet on the right turn off to the right and the left faucet turn off to the left. But you will definitely experience both types.

In both music and poetry, at least in the culture I am most familiar with, translational symmetry is more common than mirror symmetry. It does sometimes happen that musical composers experiment with playing a tune backwards or even with the staff turned upside down. But this is far less common than repeating a theme or melody. Similarly, a rhyme scheme like ABCABC is much more common than is ABCCBA. {In this notation, ABCABC means that the first line rhymes with the fourth line, the second line rhymes with the fifth line and the third line rhymes with the sixth line.}

In biology, we also find translational symmetry or something close to it. The segments of a tape worm, the segments of the body of a millipede or centipede, the small legs of a lobster, and even our own vertebrae and ribs show translational symmetry. In social structures as well, we find both mirror symmetry and translational symmetry. For instance, the Golden Rule says to do unto others as you would have them do unto you. In addition, as it happens, if we are nicer to other people, then, generally speaking, they are also nicer to us. This is not always true, however. Some people simply take advantage and view all of life as a zero sum game. Whatever you gain, they lose and vice versa. This is a very limited, inaccurate, and self-defeating attitude in most social situations. Most social situations, are, of course, much more complicated. Generally speaking, there are a great many situations that both you and your “opponent” or even your “enemy” would agree are good and a great many others that both of you would agree are bad. If you are playing tennis or golf outdoors, for instance, you may be fiercely competitive but both of you would probably find a game that brings out the best play is better for both of you. Both of you would probably also agree that being rained out is a bad outcome.

In the military and in many industrial settings, there is a great deal of translational symmetry. The “ideal” set-up is to have many groups at each of many levels and each group is meant to be as similar as possible to all the other groups at that level. The marching that military groups learn is both symbolic of this translational symmetry and practice in behaving as a unit composed of identical parts. Whether or not this is the best way to run a military is debatable. To me, it’s undeniable that this management style has been imported into a huge number of organizations where it is definitely not the best way to organize.

The last thing to note is that symmetry also pops up in design. There is often a whole series of information exchanges from people who have quite different areas of expertise. These exchanges can result in mutual learning, solutions that work, and often patents, and occasionally, some really cool, transcendent, game-changing designs. In my experience, it is much better to have a design process based on symmetrical relationships founded in mutual respect than to have a design process based on having someone in a hierarchical power relationship make decisions that are to be implemented by an identical set of “underlings.”

The Takeaway

Symmetry is everywhere. There are many forms. If you start looking for symmetry, you will find examples in nature, in mathematics, poetry, art, music, machine design, the military and even in design problems and design processes. Thinking quite consciously about the types of symmetry that exist in a problem space and what could or should exist in that problem space, can lead to novel solutions.

Non-linearity

A Chessboard Full of Rice

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

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

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

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

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

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

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

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

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

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

The Lily Pad Pond Puzzle.

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

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

The Ping Pong Table Ping Pong Player Population

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

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

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

At zero.

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

Warring Positive Feedback Loops.

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

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

Behind Every Abstraction are a Host of Personal Stories.

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

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

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

The Takeaway

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

They often aren’t.

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

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

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

Problem Finding

Problem Finding

Today, I googled “problem solving” and it returned 287,000,000 results. In most of our school life as well as most people’s work life, we are given problems and asked to solve them. “Problem finding” only returned about 2.5 million or fewer than 1/100th as many hits. Solving problems can make processes more efficient and more effective. Solving problems can even save lives. We generally reward people both at school and at work for being good problem solvers. We seldom train people in problem finding. In fact, the reaction of many teachers and many managers when someone finds a problem is to dismiss it as being a non-problem.

I can understand this sentiment. As a teenager driving my dad’s car home from a date with my girlfriend, somebody beside me tried to make a right turn from the left lane and ran right into my dad’s blue Dodge. I heard what sounded like the voice of God say “NO!!” loud and clear. It was actually louder than the sound of crumpling metal. For a split second, I was in complete denial. Even some moments later, when we pulled over to assess the damage, it looked minor enough to ignore in my mind and just drive off. A more experienced guy from the corner gas station near where this happened said that while it may look minor, it would cost hundreds of dollars to fix and we therefore needed to trade information. I was stunned.

In many cases, it is a human tendency to want to deny that a problem really exists. If you can get past that tendency however, and embrace problems and indeed, even learn to seek them out, you may be able to create tremendous value for yourself and for those around you. Problem solving can make your bookstore more profitable. Problem finding lets you invent Amazon. Problem solving lets you build a better internal combustion engine. Problem finding leads you to a Tesla.

What might you do to discover problems? First, you might take your own negative emotions as a jumping off place. If you find yourself angry, or anxious, or depressed, to the extent that you can trace back what is going on to the initiating event, you may be able to be consider whether that event is unique to you — or, more likely, that event is likely to trigger a negative reaction in many people.

If you found waiting even 48 hours to have your photographs developed and printed — and you thought others might also be impatient to see the results, you might invent Polaroid instant photos. If you found cooking a casserole too time-consuming and messy for your taste, you might invent frozen dinners. If you drove a lot in hot, humid climates, you might be motivated to put air conditioning in cars.

Of course, you do not have to limit yourself to your own misfortune. If you read about someone having a miserable time, you could dig a little deeper and ask yourself how a tragedy might have been prevented or how an accident could have been avoided. You can also look at a change that seems minor and ask yourself what will happen if this change becomes widespread.

For example, if you read in the newspaper that a robot has been invented that harvests tomatoes, you might extrapolate to a more universal situation. What if all crops were harvested by machine? This might make groceries cheaper. But what else would it mean? Tomatoes are rather delicate, after all. You might wonder whether growers using a machine to harvest tomatoes would harvest them early to avoid them being mashed by the machine. You might wonder whether they would even genetically alter the tomatoes so that they were easier to harvest by machine (even if they were no longer as tasty). You might wonder what will happen to the tomato pickers? Politicians may tell you that they will all be retrained for higher paying jobs as machine inventors, machine programmers, and machine maintenance folks. But this makes no sense. If there were an equal number of IT jobs as there used to be tomato pickers but each of the new jobs came with a higher salary, why would the growers use robots? There will be fewer jobs after automation and in some cases, far fewer.

You might look at the global temperature trends and ask yourself what will happen if they continue. What will happen if global temperatures continue to rise? What can be done about it? Of course, once people start seriously mapping out the consequences, some people will react by saying, “Oh, it isn’t really happening!.” Why do they think that? Because it’s too scary to contemplate the truth; or too inconvenient to take the necessary actions. There are vested interests in old energy sources who will be happy to help you along in your fantasy of denial. In the short run, it’s often easier to imagine that problems do not exist, or are not that bad, or won’t get worse, or that there is just nothing to be done.

Even most of the people who rail against what most of us think of as sensible gun regulation (requiring a license, showing ID, getting at least some training and testing the would-be gun owner’s knowledge, competency, and eyesight as we do with cars) don’t think that mass shootings of innocent children is a fine thing. They see it as a problem — just one that cannot be solved or one that can only be solved by adding cost and inconvenience to the potential victims. After such a tragedy, they may even send “thoughts and prayers.”

There is a possible “down side” to problem finding. The greedy may decide that they can make a lot of money by generating a solution to a problem that isn’t really a problem and making you believe it is a problem. My favorite, and so far made up, example is “Elbow Cream” for those unsightly skin wrinkles that appear on the back of your elbow when you straighten your arm. But that made up example is not too far off. You eat spicy food and it upsets your stomach? We can fix that! Of course, you could too by not eating spicy food! But nobody makes money that way. So they will sell you something that supposedly fixes the “problem.” While it might be fantasy to imagine “Elbow Cream” that will “fix” your “unsightly elbow wrinkles” it is not fantasy to imagine that people have been hoodwinked into spending money on “fixing” their faces and bodies.

Americans spent 16 billion dollars on cosmetic plastic surgery in 2017. There are 50 countries who each have a lower GDP than that. The beauty industry in the USA overall was supposedly around $445 billion in 2017. That’s more than the GDP of each of 151 countries! Both figures are also less than the federal government spends on reducing climate change. Or cancer research.

Do you see that as a problem? I do.

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….

Representation

Representation

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

PicturesfromiPhone 080

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Theory of Mind

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

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.
