THE PSYCHOLOGY OF HUMAN MISJUDGMENT: 3

6. Sixth: bias from reciprocation tendency, including the tendency of one o­n a roll to act as other persons expect.Well here, again, Cialdini does a magnificent job at this, and you're all going to be given a copy of Cialdini's book. And if you have half as much sense as I think you do, you will immediately order copies for all of your children and several of your friends. You will never make a better investment.It is so easy to be a patsy for what he calls the compliance practitioners of this life. At any rate, reciprocation tendency is a very, very powerful phenomenon, and Cialdini demonstrated this by running around a campus, and he asked people to take juvenile delinquents to the zoo. And it was a campus, and so o­ne in six actually agreed to do it. And after he'd accumulated a statistical output he went around o­n the same campus and he asked other people, he said, "Gee, would you devote two afternoons a week to taking juvenile delinquents somewhere and suffering greatly yourself to help them," and there he got 100% of the people to say no. But after he'd made the first request, he backed up a little, and he said, "Would you at least take them to the zoo o­ne afternoon?" He raised the compliance rate from a third to a half. He got three times the success by just going through the little ask-for-a-lot-and-back-off.

Now if the human mind, o­n a subconscious level, can be manipulated that way and you don't know it, I always use the phrase, "You're like a one-legged man in an ass-kicking contest." I mean you are really giving a lot of quarter to the external world that you can't afford to give. And o­n this so-called role theory, where you tend to act in the way that other people expect, and that's reciprocation if you think about the way society is organized.

A guy named Zimbardo had people at Stanford divide into two pieces: o­ne were the guards and the other were the prisoners, and they started acting out roles as people expected. He had to stop the experiment after about five days. He was getting into human misery and breakdown and pathological behavior. I mean it was...it was awesome. However, Zimbardo is greatly misinterpreted. It's not just reciprocation tendency and role theory that caused that, it's consistency and commitment tendency. Each person, as he acted as a guard or a prisoner, the action itself was pounding in the idea.

[For more o­n this famous experiment: http://www.prisonexp.org/] Wherever you turn, this consistency and commitment tendency is affecting you.

In other words, what you think may change what you do, but perhaps even more important, what you do will change what you think. And you can say, "Everybody knows that." I want to tell you I didn't know it well enough early enough.

7. Seventh, now this is a lollapalooza, and Henry Kaufman wisely talked about this: bias from over-influence by social proof -- that is, the conclusions of others, particularly under conditions of natural uncertainty and stress.And here, o­ne of the cases the psychologists use is Kitty Genovese, where all these people -- I don't know, 50, 60, 70 of them -- just sort of sat and did nothing while she was slowly murdered. Now o­ne of the explanations is that everybody looked at everybody else and nobody else was doing anything, and so there's automatic social proof that the right thing to do is nothing. That's not a good enough explanation for Kitty Genovese, in my judgment. That's o­nly part of it. There are microeconomic ideas and gain/loss ratios and so forth that also come into play. I think time and time again, in reality, psychological notions and economic notions interplay, and the man who doesn't understand both is a damned fool.

Big-shot businessmen get into these waves of social proof. Do you remember some years ago when o­ne oil company bought a fertilizer company, and every other major oil company practically ran out and bought a fertilizer company? And there was no more damned reason for all these oil companies to buy fertilizer companies, but they didn't know exactly what to do, and if Exxon was doing it, it was good enough for Mobil, and vice versa. I think they're all gone now, but it was a total disaster.

Now let's talk about efficient market theory, a wonderful economic doctrine that had a long vogue in spite of the experience of Berkshire Hathaway. In fact o­ne of the economists who won -- he shared a Nobel Prize -- and as he looked at Berkshire Hathaway year after year, which people would throw in his face as saying maybe the market isn't quite as efficient as you think, he said, "Well, it's a two-sigma event." And then he said we were a three-sigma event. And then he said we were a four-sigma event. And he finally got up to six sigmas -- better to add a sigma than change a theory, just because the evidence comes in differently. [Laughter] And, of course, when this share of a Nobel Prize went into money management himself, he sank like a stone.

If you think about the doctrines I've talked about, namely, o­ne, the power of reinforcement -- after all you do something and the market goes up and you get paid and rewarded and applauded and what have you, meaning a lot of reinforcement, if you make a bet o­n a market and the market goes with you. Also, there's social proof. I mean the prices o­n the market are the ultimate form of social proof, reflecting what other people think, and so the combination is very powerful. Why would you expect general market levels to always be totally efficient, say even in 1973-74 at the pit, or in 1972 or whatever it was when the Nifty 50 were in their heyday? If these psychological notions are correct, you would expect some waves of irrationality, which carry general levels, so they're inconsistent with reason.

8. Nine [he means eight]: what made these economists love the efficient market theory is the math was so elegant.

And after all, math was what they'd learned to do. To the man with a hammer, every problem tends to look pretty much like a nail. The alternative truth was a little messy, and they'd forgotten the great economists Keynes, whom I think said, "Better to be roughly right than precisely wrong."

9. Bias from contrast-caused distortions of sensation, perception and cognition.Here, the great experiment that Cialdini does in his class is he takes three buckets of water: o­ne's hot, o­ne's cold and o­ne's room temperature, and he has the student stick his left hand in the hot water and his right hand in the cold water. Then he has them remove the hands and put them both in the room temperature bucket, and of course with both hands in the same bucket of water, o­ne seems hot, the other seems cold because the sensation apparatus of man is over-influenced by contrast. It has no absolute scale; it's got a contrast scale in it. And it's a scale with quantum effects in it too. It takes a certain percentage change before it's noticed.

Maybe you've had a magician remove your watch -- I certainly have -- without your noticing it. It's the same thing. He's taking advantage of contrast-type troubles in your sensory apparatus. But here the great truth is that cognition mimics sensation, and the cognition manipulators mimic the watch-removing magician. In other words, people are manipulating you all day long o­n this contrast phenomenon.

Cialdini cites the case of the real estate broker. And you've got the rube that's been transferred into your town, and the first thing you do is you take the rube out to two of the most awful, overpriced houses you've ever seen, and then you take the rube to some moderately overpriced house, and then you stick him. And it works pretty well, which is why the real estate salesmen do it. And it's always going to work.And the accidents of life can do this to you, and it can ruin your life. In my generation, when women lived at home until they got married, I saw some perfectly terrible marriages made by highly desirable women because they lived in terrible homes. And I've seen some terrible second marriages which were made because they were slight improvements over an even worse first marriage. You think you're immune from these things, and you laugh, and I want to tell you, you aren't.

My favorite analogy I can't vouch for the accuracy of. I have this worthless friend I like to play bridge with, and he's a total intellectual amateur that lives o­n inherited money, but he told me o­nce something I really enjoyed hearing. He said, "Charlie," he say, "If you throw a frog into very hot water, the frog will jump out, but if you put the frog in room temperature water and just slowly heat the water up, the frog will die there." Now I don't know whether that's true about a frog, but it's sure as hell true about many of the businessmen I know [laughter], and there, again, it is the contrast phenomenon. But these are hot-shot, high-powered people. I mean these are not fools. If it comes to you in small pieces, you're likely to miss, so if you're going to be a person of good judgment, you have to do something about this warp in your head where it's so misled by mere contrast.

10. Bias from over-influence by authority. Well here, the Milgrim experiment, as it's called -- I think there have been 1,600 psychological papers written about Milgrim. And he had a person posing as an authority figure trick ordinary people into giving what they had every reason to expect was heavy torture by electric shock to perfectly innocent fellow citizens. And he was trying to show why Hitler succeeded and a few other things, and so this really caught the fancy of the world. Partly it's so politically correct, and over-influence by authority...You'll like this o­ne: You get a pilot and a co-pilot. The pilot is the authority figure. They don't do this in airplanes, but they've done it in simulators. They have the pilot do something where the co-pilot, who's been trained in simulators a long time -- he knows he's not to allow the plane to crash -- they have the pilot to do something where an idiot co-pilot would know the plane was going to crash, but the pilot's doing it, and the co-pilot is sitting there, and the pilot is the authority figure. 25% of the time the plane crashes. I mean this is a very powerful psychological tendency. It's not quite as powerful as some people think, and I'll get to that later.
