The Psychology of Human Misjudgment

One of my favorite cases about the power of incentives is the Federal Express case. The heart and soul of the integrity of the system is that all the packages have to be shifted rapidly in one central location each night. And the system has no integrity if the whole shift can’t be done fast. And Federal Express had one hell of a time getting the thing to work. And they tried moral suasion, they tried everything in the world, and finally, somebody got the happy thought that they were paying the night shift by the hour and that maybe if they paid them by the shift, the system would work better. And lo and behold, that solution worked…

Early in the history of Xerox, Joe Wilson, who was then in the government, had to go back to Xerox because he couldn’t understand how their better, new machine was selling so poorly in relation to their older and inferior machine. Of course, when he got there he found out that the commission arrangement with the salesmen gave a tremendous incentive to the inferior machine…

But, at any rate, reciprocation tendency is a very, very powerful phenomenon, and Cialdini demonstrated this by running around 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 off a little, and he said, “Would you at least take them to the zoo one afternoon?” He raised the compliance rate from a sixth to a half. He got three times the success by just going through the little ask-for-a-lot-and-back-off.

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…

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.

Over-influence by authority has another very … you’ll like this one. You got 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 gonna 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. This is a very powerful psychological tendency.

Here I took the Munger dog, a lovely harmless dog. The one way, the only way to get that dog to bite you was to try and take something out of its mouth after it was already there…

Any of you who’ve tried to do take-aways in labor negotiations will know the human version of that dog is there in all of us. I had a neighbor, a predecessor, on a little island where I have a house, and his next-door neighbor put a little pine tree in that was about three feet high, and it turned his 180-degree view of the harbor into 179 and three-quarters. Well, they had a blood feud like the Hatfields and McCoys, and it went on and on and on. People are really crazy about minor decrements down.

Ask the Coca-Cola company, which has raised availability to a secular religion, if availability changes behavior. You’ll drink a hell of a lot more Coke if it’s always available. Availability does change behavior and cognition.

One of my favorite cases is the McDonald-Douglas airliner evacuation disaster. The government requires that airliners pass a bunch of tests. One of them is evacuation. Get everybody out, I think it’s 90 seconds or something like that. It’s some short period of time. The government has rules, make it very realistic, so on, and so on. You can’t select nothing but 20-year-old athletes to evacuate your airline.

So McDonald-Douglas schedules one of these things in a hangar, and they make the hangar dark. The concrete floor is 25 feet down, and they got these little rubber chutes, and they got all these old people. They ring the bell, and they all rush out. In the morning when the first test is done, they create, I don’t know, 20 terrible injuries.

People go off to hospitals. Of course, they scheduled another one for the afternoon. By the way, they didn’t meet the time schedule either, in addition to causing all the injuries. So what do they do? They do it again in the afternoon. Now, they create 20 more injuries and one case of a severed spinal column with permanent, unfixable paralysis. They’re engineers. These are brilliant people. This is thought over through in a big bureaucracy…

Authorities told you to do it. He told you to make it realistic. You’ve decided to do it. You’d decided to do it twice. Incentive-caused bias. If you pass, you save a lot of money. You’ve got to jump this hurdle before you can sell your new airliner.

Again, three, four, five of these things work together, and it turns human brains into mush.
