Why Experts Create Few New Ideas

I have always been intrigued by the paradox of expertise. It seems that the more expert one becomes in an area of specialization, the less creative and innovative that person becomes. The paradox is that people who know more, see less; and the people who know less, see more.

Apple Computer Inc. founder Steve Jobs attempted without success to get Atari and Hewlett-Packard interested in his and Steve Wozniak’s personal computer. As Steve recounts, “So we went to Atari and said, ‘Hey, we’ve got this amazing thing, even built with some of your parts, and what do you think about funding us? Or we’ll give it to you. We just want to do it. Pay our salary; we’ll come work for you.’ And their experts laughed and said, ‘No.’ So then we went to Hewlett-Packard, and they said, ‘Hey, we don’t need you. You haven’t got through college yet.”

What is it that freezes the expert’s thought and makes it difficult to consider new things that deviate from their theories?

The figure below illustrates a series of progressively modified drawings that change almost imperceptibly from a man into a woman. When test subjects are shown the entire series of drawings one by one, their perception of this intermediate drawing is biased according to which end of the series they started from. Test subjects who start by viewing a picture that is clearly a man are biased in favor of continuing to see a man long after an “objective observer” (an observer who has seen only a single picture) recognizes that the man is now a woman. Similarly, test subjects who start at the woman end of the series are biased in favor of continuing to see a woman. Once an observer has formed an image–that is, once he or she has developed an expectation concerning the subject being observed–this influences future perceptions of the subject.

Ken Olson, president, chairman and founder of Digital Equipment Corp., thought the idea of a personal computer absurd, as he said, “there is no reason anyone would want a computer in their home.” Robert Goddard, the father of modern rocketry, was ridiculed by every scientist for his revolutionary liquid-fueled rockets. Even the New York Times chimed in with an editorial in 1921 by scientists who claimed that Goddard lacked even the basic knowledge ladled out daily in high school science classes. Pierrre Pachet a renowned physiology professor and expert declared, “Louis Pasteur’s theory of germs is ridiculous fiction.”

If we experience any strain in imagining a possibility, we quickly conclude it’s impossible. This principle also helps explain why evolutionary change often goes unnoticed by the expert. The greater the commitment of the expert to their established view, the more difficult it is for the expert to do anything more than to continue repeating their established view. It also explains the phenomenon of a beginner who comes up with the breakthrough insight or idea that was overlooked by the experts who worked on the same problem for years.

There is also a tendency to assimilate new data into pre-existing images. In the early 1900s Psychologist Cheves W. Perky demonstrated this principle in several experiments. She would ask a group of subjects to form a mental image of a banana, and to mentally project it on a blank wall. She then surreptitiously projected a very dim slide of a banana. Anyone coming into the room sees the slide immediately, but the subjects did not. Perky claimed that the subjects incorporated the slide into their mental image of a banana. State-of-the-art experiments have borne out what is now called the Perky effect: holding a mental image interferes perception and understanding.

This is why experts always assimilate new insights, ideas and concepts into their view. Their mental image of the established view interferes with their perception and understanding of new ideas and concepts. In the case of the Perky experiment with the slide of a banana, the students did not see the slide. In the case of real life, physicists could not see Einstein’s theory of relativity because of their established, accepted view. For years, they tried to incorporate his view into the established view without success.

What happened in this experiment is what happens in real life; despite ambiguous stimuli, people form some sort of tentative hypothesis about what they see. The longer they are exposed to this blurred image, the greater confidence they develop in this initial and perhaps erroneous impression, so the greater the impact this initial hypothesis has on subsequent perceptions.

Suppose an expert has an established theory about the danger of boxes and their effect on human life and the environment. The theory is that boxes might be harmful and the use of boxes should be regulated. Now, suppose that I leave a box on the floor, and my wife trips on it, falling against my son, who is carrying a carton of eggs, which then fall and break.  The expert’s approach to an event like this would be that the best way to prevent the breakage of eggs would be to outlaw leaving boxes on the floor. As silly as this example is, it is analogous to what is happening in the world of global warming. The chief difference is that in the case of atmospheric CO2 and climate catastrophe, the chain of inference is longer and less plausible than in my example.

If you survey the history of science, it is apparent that most individuals who have created radical innovations did not do so simply because they knew more than others. One of the most important experiences Noble laureate Richard Feynman had in his life was reading a copy of the James Watson’s typescript of what was to become his famous book The Double Helix, about his discovery, together with Francis Crick, of the structure of DNA. Feynman had become unproductive and began to believe he had run out of ideas. The discovery Feynman made was that Watson had been involved in making such a fundamental advance in science, and yet he had been completely out of touch with what everybody else in his field was doing.

As told in Watson’s classic memoir, “The Double Helix,” it was a tale of boundless ambition, impatience with authority and disdain, if not contempt, for received opinion. “A goodly number of scientists,” Watson explained, “are not only narrow-minded and dull but also just stupid.” Feynman wrote one word, in capitals: DISREGARD on his notepad when he read that. This word became his motto. That, he said, was the whole point. That was what he had forgotten, and why he had been making so little progress. The way for thinkers like himself to make a breakthrough was to be ignorant of what everybody else was doing and make their own interpretations and guesses.

So Feynman “stopped trying to keep up with what others were doing and went back to his roots, comparing experiment with theory, making guesses that were all his own.” Thus he became creative again, as he had been when he had just been working things out for himself, before becoming a famous physicist in academia. While this is an important lesson for science, it is a supreme lesson for any discipline where “current knowledge” can be dominated that are simply incoherent, overlooked by the experts who worked on the same problem for years.

Make your own interpretations of your experiences to shape your own beliefs and concepts about your world. This is the lesson Feynman called the most important of his life.

Are Your Memories True or False?

EGG

A few years ago, the actor Alan Alda, visited a group of memory researchers at the University of California, Irvine, for a TV show he was making. During a picnic lunch, one of the scientists offered Alda a hard-boiled egg. He turned it down, explaining that as a child he had made himself sick eating too many eggs.

In fact, this had never happened, yet Alda believed it was real. How so? The egg incident was a false memory planted by one of UC Irvine’s researchers, Elizabeth Loftus. Before the visit, Loftus had sent Alda a questionnaire about his food preferences and personality. She later told him that a computer analysis of his answers had revealed some facts about his childhood, including that he once made himself sick eating too many eggs. There was no such analysis but it was enough to convince Alda.

Your memory may feel like a reliable record of the past, but it is not. Loftus has spent the past 30 years studying the ease with which we can form “memories” of nonexistent events. She has convinced countless people that they have seen or done things when they haven’t – even quite extreme events such as being attacked by animals or almost drowning. Her work has revealed much about how our brains form and retain memories.

While I wouldn’t want to plant a memory of a nonexistent childhood trauma in your own brain, there is a less dramatic demonstration of how easy it is to form a false memory called the Deese-Roediger-McDermott paradigm. Try the following thought experiment:

THOUGHT EXPERIMENT

Read the first two lists of words and pause for a few minutes. Then read list 3 and put a tick against the words that were in the first two. Now go back and check your answers…

List 1

apple, vegetable, orange, kiwi,

citrus, ripe, pear, banana, berry,

cherry, basket, juice, salad, bowl,

cocktail

.

.

List 2

web, insect, bug, fright, fly,

arachnid, crawl, tarantula, poison,

bite, creepy, animal, ugly, feelers, small

.

.

NOW WAIT A FEW MINUTES. THEN SCROLL DOWN.

.

.

Check the following words that you remember from being on List 1 or List 2

Spider, feather, citrus, ugly, robber,

Piano, goat, ground, cherry, bitter,

Insect, fruit, suburb, kiwi, quick,

Mouse, pile, fish

How to Reverse Your Perspective to Create New Idea

old lady or young girl

Is this an illustration of an old woman or a young girl?

Many times we have to change our psychology to understand certain phenomena. Think of Michelangelo when he sculpted what may be the world’s most famous sculpture, David. He did not think of “building” something; he thought of “taking away” something from what was there. A quotation often attributed to him has it that “the more the marble wastes away, the more the sculpture grows.”

To understand a mirror you have to change your psychology. Why does a mirror seem to invert left and right but not top and bottom? That is, when you hold an open book up to a mirror, why are the letters of the text backward but not upside down, and why is your left hand the double’s right and your right the double’s left? When we look into a mirror we imagine ourselves reversed left to right, as if we had walked around behind a pane of glass to look through it. This conventional perspective is why we cannot explain what is happening with a mirror. To understand a mirror’s image, you have to psychologically reverse the way you perceive your image. Imagine your nose and the back of your head reversed, through the mirror. You have to imagine yourself reversed, “squashed” back to front. Stand in front of the mirror with one hand pointing east and the other west. Wave the east hand. The mirror image waves its east hand. Its west hand lies to the west. Its head is up and the feet are down. Once you look at a mirror with this perspective, you gain an understanding, about the axis of the mirror, which is the imaginary line on a mirror about which a body rotates. We have difficulty understanding the mirror until we change our perspective.

Similarly, we sometimes have difficulty coming up with ideas until we change our psychology. Early nomadic societies were all based on the principle of “getting to the water.” Only when they reversed this to “how can we get the water to come to us” did civilization begin to flourish. An easy way to change your thinking patterns when faced with a problem is to first list all your assumptions about the problem. Then reverse your assumptions and try to make the reversals work.

Following is a thought experiment about reversing a store policy. After you read the problem, try to come up with ideas before you read further.

THOUGHT EXPERIMENT

A clothing retailer is concerned about the rate of garment returns. According to the store policy, a customer who returns a garment must receive a cash refund. Reverse this policy so that it says: if a customer returns a garment, the store doesn’t have to give a cash refund. Can you come up with ideas to make this reversal into a practical solution?

……………………………

What can the store give the customer instead of a refund? One idea is to offer the customer a gift certificate worth more than the original purchase price. In effect this gives the customer a 10 percent reward for returning the unwanted garment. The policy would allow the store to keep most of the cash, and the customers would likely be happy with the reward. The real payback would occur when the customer returned with the gift certificate. A customer who returned a $100 garment would receive a gift certificate for $110. Psychology predicts that, when the customer returns to the store, he will go to the higher priced garments. For example, instead of shopping for an $l00 garment, he will be attracted to the $200 garments because, in his mind, it would “cost” him only $90. What a deal! Change the way you look at things by reversing them and looking at the other side.

Rearrange the letters in words to discover how words self-define themselves

 Santa

 

Creativity, it could be said, consists largely of rearranging what we know in order to find out what we do not know. Rearrangement usually offers countless alternatives for ideas, goods, and services. A baseball manager, for example, can shuffle his lineup 362,880 times

Take ordinary words and rearrange the letters to create new words that will surprise and startle you. For example, if life gives you limes, rearrange the letters of limes into smile :) Other examples:

ASTRONOMER: When you rearrange the letters, it becomes:

MOON STARER

ELECTION RESULTS: When you rearrange the letters:

LIES – LET’S RECOUNT

SLOT MACHINES: When you rearrange the letters:

CASH LOST IN ME

ANIMOSITY: When you rearrange the letters:

IS NO AMITY

DORMITORY: When you rearrange the letters:

DIRTY ROOM

PRESBYTERIAN: When you rearrange the letters:

BEST IN PRAYER

THE EYES: When you rearrange the letters:

A SURREAL IDEA

surreal

André Breton was a French writer and poet. He is known best as the founder of surrealism. The surrealists sought to overthrow the oppressive rules of society by demolishing its backbone of rational thought. To do so, they attempted to tap into the “superior reality” of the subconscious mind. “Completely against the tide,” said Breton, “in a violent reaction against the impoverishment and sterility of thought processes that resulted from centuries of rationalism, we turned toward the marvelous and advocated it unconditionally.” 

Many of the tenets of surrealism included an emphasis on the actual functioning of thought…in the absence of any control exercised by reason. They created many exercises designed to probe the subconscious by getting the minds to be as passive and receptive as possible. 

One day I had a long discussion with a friend about the Japanese whaling industry and their illegal poaching practices. After the discussion, I decided to experiment with one of Andre Breton’s surrealist exercises. The exercise has 3 small, grid like areas and one large grid on a sheet of paper.  

DOT_0001

The first rule of the exercise was to always forget your genius, talents, as well as the genius and talents of others. Try not to think about what you are doing—just let your automatic functions take over, letting them proceed as they wish. Your final solution will not come from your normal way of solving problems, but from a deeper, more intuitive impulse. So whatever happens, let it happen. The guidelines are:

  • Think of a problem. Don’t dwell on it and dismiss it from your thoughts. Look at the design below with the grids.
  • Use the 3 small grids at the top to create an image in the spirit of your unconscious. Try not to think of what you’re doing…just let your automatic functions take over, letting them proceed as they wish.
  • Then with the large grid on the bottom revert to your usual way of thinking and impose your will to create whatever imagery, abstract or literal you wish.

My problem was how to control the illegal whale harvesting by the Japanese whalers. In the small grids I drew one squiggle that looked like a human skull, one that looked like quotation markets and one that looked like a rose. In the large grid I drew a stick figure of a man with two profiles: one looking left and one looking right.

I pondered over my drawings for a long time. The skull reminded me of a pirate’s black flag; the quotation marks reminded me of a quote “The opposite of a profound truth is another truth; and the rose reminded me of the roses I give my wife to celebrate our union as husband and wife. The stick figure in the large grid reminded me of the ambiguity in all aspects of life e.g., no one is all good or all evil.

These images combined and recombined in my imagination and inspired the thought of one way of fighting an illegal activity is to use an illegal enforcement activity. The pirate’s flag reminded me of the Somalian pirate ships off the coast of Africa. The rose got me thinking of combining two illegal activities. The stick figure made me think of looking the other way when something illegal is accomplishing something good.

My final idea all this inspired is to make it legal for the Somali pirates to hijack illegal Japanese Whalers and hold them for ransom.

Now it’s your turn to give it a try.

Let’s Keep Doing What We’ve Always Done

geese

A certain flock of geese lived together in a barnyard with high walls around it.  Because the corn was good and the barnyard was secure, these geese learned to always do the same things over and over and to live orderly and predictable lives with no surprises. This primarily meant never take a risk or do anything new. Over time the geese became so lazy they even forgot how to fly. They were safe and secure in their barnyard where everything is familiar and nothing ever changes. In short, they always did what they always did and always got what they always got.

One day a philosopher goose came among them. He was a very good philosopher and every week they listened quietly and attentively to his learned discourses. “My fellow geese,” he would say, “can you seriously imagine that this barnyard, with great high walls around it, is all there is to existence? Don’t you realize you can fly and change the way you live? You were all born as spontaneous and natural fliers. All you need do is live the way you were meant to live and fly.” “I tell you, there is another and a greater world outside, a world of which you are only dimly aware.

Our forefathers knew of this outside world. For did they not stretch their wings and fly across the trackless wastes of desert and ocean, of green valley and wooded hill? But alas, here you remain in this barnyard, your wings folded and tucked into your sides, as you are content to puddle around in the mud, never lifting your eyes to the heavens which should be your home.”

The geese thought this was very fine lecturing. “How poetical,” they thought. “How profoundly existential. What a flawless summary of the mystery of existence.” Often the philosopher spoke of the advantages of flight, calling on the geese to get off their butts and fly. After all, they had wings, he pointed out. What were wings for, but to fly with?

The philosopher urged the geese to experience the joys of doing different things and looking at the world in a different way. “Fly,” he would say. “Don’t wait for divine inspiration. Inspiration will never come. Just do it. Get up and fly.” Often he reflected on the joys on controlling your own destiny in the freedom of the skies while you enjoyed the beauty and the wonder of life as they were born to do.

And every week the geese were uplifted, inspired, moved by the philosopher’s message. They hung on his every word. They devoted hours, weeks, and months to a thoroughgoing analysis and critical evaluation of his doctrines. They created computer models, charts and graphs displaying the physics and dynamics of flight. They produced learned treatises on the ethical and spiritual implications of flight. They held meetings and talked endlessly about the importance and need to fly. They all agreed that flying would make a much better life possible. All this they did. But one thing they never did. They did not fly! They were afraid of the uncertainty of living in a different way. For the corn was good, and the barnyard was secure!

Are You Like the Geese?

At one time Eastman Kodak was one of the premier companies in the world. The people who worked there were prosperous, had wonderful salaries, bonuses, comprehensive health and medical benefits, and superior pensions. Everybody was happy. It seemed like there was no end to its prosperity. Kodak advertised itself internationally as being a very creative and innovative company. They hired the top creative thinkers in the fields of photography and film. They came up with scores of brilliant ideas such as digital photography, and were among the first to design a digital photography camera.

They had all these cutting edge ideas years before their competition, but they implemented not a single one because of the fear of new ideas. Kodak clung to its aging familiar technology. They wanted to hang on to their historical revenue streams. They thought, “We know we’re making a lot of money with film. We don’t know if we’re going to make money with these new ideas. Let’s keep doing what we’ve always done.” Consequently, not one of these innovative ideas–not one–was accepted or implemented. It was an organization which could not transform itself by accepting and implementing new ideas. So the reality of the business world transformed Kodak from being a major player into a bankrupt shell.

Kodak CEOs and top managers feared the new ideas. They wanted to be absolutely certain everything would work flawlessly and the money would continue to flow, which, of course, is impossible to predict with new ideas. In the end, Kodak management behaved like the flock of geese in the barnyard and never did fly.

ARE YOU COGNITIVELY LAZY?

THINKING

We have not been taught how to think for ourselves, we have been taught what to think based on what past thinkers thought. We are taught to think reproductively, not productively. What most people call thinking is simply reproducing what others have done in the past. We have been trained to seek out the neural path of least resistance, searching out responses that have worked in the past, rather than approach a problem on its own terms.

Educators discourage us from looking for alternatives to prevailing wisdom. When confronted with a problem, we are taught to analytically select the most promising approach based on past history, excluding all other approaches and then to work logically within a carefully defined direction towards a solution. Instead of being taught to look for possibilities, we are taught to look for ways to exclude them. This kind of thinking is dehumanizing and naturalizes intellectual laziness which promotes an impulse toward doing whatever is easiest or doing nothing at all. It’s as if we entered school as a question mark and graduated as a period.

Once when I was a young student, I was asked by my teacher, “What is one-half of thirteen?” I answered six and one half or 6.5. However, I exclaimed there are many different ways to express thirteen and many different to halve something. For example, you can spell thirteen, then halve it (e.g., thir/teen). Now half of thirteen becomes four (four letters in each half). Or, you can express it numerically as 13, and now halving 1/3 gives you 1 and 3. Another way to express a 13 is to express it in Roman numerals as XIII and now halving XI/II gives you XI and II, or eleven and two. Consequently one-half of thirteen is now eleven and two. Or you can even take XIII, divide it horizontally in two (XIII) and half of thirteen becomes VIII or 8.

My teacher scolded me for being silly and wasting the class’s time by playing games. She said there is only one right answer to the question about thirteen. It is six and one-half or 6.5. All others are wrong. I’ll never forget what she said “When I ask you a question, answer it the way you were taught or say you don’t know. If you want to get a passing grade, stop making stuff up.”

When we learn something, we are taught to program it into our brain and stop thinking about or looking for alternatives. Over time these programs become stronger and stronger, not only cognitively but physiologically as well. To get a sense of how strong these programs are, try solving the following problem.

Even when we actively seek information to test our ideas to see if we are right, we usually ignore paths that might lead us to discover alternatives. Following is an interesting experiment, which was originally conducted by the British psychologist Peter Wason that demonstrates this attitude. Wason would present subjects with the following triad of three numbers in sequence.

2       4       6

He would then ask subjects to write other examples of triads that follow the number rule and explain the number rule for the sequence. The subjects could ask as many questions as they wished without penalty.

He found that almost invariably most people will initially say, “4, 6, 8,” or “20, 22, 24,” or some similar sequence. And Watson would say, yes, that is an example of a number rule. Then they will say, “32, 34, 36″ or “50, 52, 54″ and so on– all numbers increasing by two. After a few tries, and getting affirmative answers each time, they are confident that the rule is numbers increasing by two without exploring alternative possibilities.

Actually, the rule Wason was looking for is much simpler– it’s simply numbers increasing. They could be 1, 2, 3 or 10, 20, 40 or 400, 678, 10,944. And testing such an alternative would be easy. All the subjects had to say was 1, 2, 3 to Watson to test it and it would be affirmed. Or, for example, a subject could throw out any series of numbers, for example, 5, 4, and 3 to see if they got a positive or negative answer. And that information would tell them a lot about whether their guess about the rule is true.

The profound discovery Wason made was that most people process the same information over and over until proven wrong, without searching for alternatives, even when there is no penalty for asking questions that give them a negative answer. In his hundreds of experiments, he, incredibly, never had an instance in which someone spontaneously offered an alternative hypothesis to find out if it were true. In short, his subjects didn’t even try to find out if there is a simpler or even, another, rule.

On the other hand, creative thinkers have a vivid awareness of the world around them and when they think, they seek to include rather than exclude alternatives and possibilities. They have a “lantern awareness” that brings the whole environment to the forefront of their attention. So, by the way, do children before they are educated. This kind of awareness is how you feel when you visit a foreign country; you focus less on particulars and experience everything more globally because so much is unfamiliar.

I am reminded of a story about a student who protested when his answer was marked wrong on a physics degree exam at the University of Copenhagen. The imaginative student was purportedly Niels Bohr who years later was co-winner of the Nobel Prize for physics.

In answer to the question, “How could you measure the height of a skyscraper using a barometer?” he was expected to explain that the barometric pressures at the top and the bottom of the building are different, and by calculating, he could determine the building’s height. Instead, he answered, “You tie a long piece of string to the neck of the barometer, then lower the barometer from the roof of the skyscraper to the ground. The length of the string plus the length of the barometer will equal the height of the building.

This highly original answer so incensed the examiner that the student was failed immediately. The student appealed on the grounds that his answer was indisputably correct, and the university appointed an independent arbiter to decide the case.

The arbiter judged that the answer was indeed correct, but did not display any noticeable knowledge of physics. To resolve the problem it was decided to call the student in and allow him six minutes in which to provide a verbal answer that showed at least a minimal familiarity with the basic principles of physics.

For five minutes the student sat in silence, forehead creased in thought. The arbiter reminded him that time was running out, to which the student replied that he had several extremely relevant answers, but couldn’t make up his mind which to use. On being advised to hurry up the student replied as follows:

“Firstly, you could take the barometer up to the roof of the skyscraper, drop it over the edge, and measure the time it takes to reach the ground. The height of the building can then be worked out from the formula H = 0.5g x t squared. But bad luck on the barometer.”

“Or if the sun is shining you could measure the height of the barometer, then set it on end and measure the length of its shadow. Then you measure the length of the skyscraper’s shadow, and thereafter it is a simple matter of proportional arithmetic to work out the height of the skyscraper.”

“But if you wanted to be highly scientific about it, you could tie a short piece of string to the barometer and swing it like a pendulum, first at ground level and then on the roof of the skyscraper. The height is worked out by the difference in the gravitational restoring force T =2 pi sqr root (I /9).”

“Or if the skyscraper has an outside emergency staircase, it would be easier to walk up it and mark off the height of the skyscraper in barometer lengths, then add them up.”

“If you merely wanted to be boring and orthodox about it, of course, you could use the barometer to measure the air pressure on the roof of the skyscraper and on the ground, and convert the difference in millibars into feet to give the height of the building.”

“But since we are constantly being exhorted to exercise independence of mind and apply scientific methods, undoubtedly the best way would be to knock on the janitor’s door and say to him ‘If you would like a nice new barometer, I will give you this one if you tell me the height of this skyscraper’.”

The obvious moral here is that education should not consist merely of stuffing students’ heads full of information and formulae to be memorized by rote and regurgitated upon demand, but of teaching students how to think and solve problems using whatever tools are available. In the mangled words of a familiar phrase, students should be educated in a way that enables them to figure out their own ways of catching fish, not simply taught a specific method of fishing.
