Psychology of Human Misjudgement - Charlie Munger

Yet another education via David Brooks - Charlie Munger's excellent Harvard University 1995 speech - PDF here:

1. And by the way, the government’s right, but a lot of the way the world is run, including most law firms and a lot of other places, they’ve still got a cost-plus percentage of cost system. And human nature, with its version of what I call ‘incentive-caused bias,’ causes this terrible abuse. And many of the people who are doing it you would be glad to have arried into your family compared to what you’re otherwise going to get.
Now there are huge implications from the fact that the human mind is put together this way, and that is that people who create things like cash registers, which make most [dishonest] behavior hard, are some of the effective saints of our civilization. And the cash register was a great moral instrument when it was created. And Patterson knew that, by the way. He had a little store, and the people were stealing him blind and never made any money, and people sold him a couple of cash registers and it went to profit immediately. And, of course, he closed the store and went into the cash register business…

2. And now the Persian messenger syndrome is alive and well. I saw, some years ago, Arco and Exxon arguing over a few hundred millions of ambiguity in their North Slope treaties before a superior court judge in Texas, with armies of lawyers and experts on each side. Now this is a Mad Hatter’s tea party: two engineering-style companies can’t resolve some ambiguity without spending tens of millions of dollars in some Texas superior court? In my opinion what happens is that nobody wants to bring the bad news to the executives up the line. But here’s a few hundred million dollars you thought you had that you don’t. And it’s much safer to act like the Persian messenger who goes away to hide rather than bring home the news of the battle lost.

3. Well what I’m saying here is that the human mind is a lot like the human egg, and the human egg has a shut-off device. When one sperm gets in, it shuts down so the next one can’t get in. The human mind has a big tendency of the same sort. And here again, it doesn’t just catch ordinary mortals; it catches the deans of physics. According to Max Planck, the really innovative, important new physics was never really accepted by the old guard. Instead a new guard came along that was less brain-blocked by its previous conclusions. And if Max Planck’s crowd had this consistency and commitment tendency that kept their old inclusions intact in spite of disconfirming evidence, you can imagine what the crowd that you and I are part of behaves like.

4. The truth of the matter is the accounting system was such that by punching a few buttons, the Joe Jetts of the world could show profits, and profits that showed up in things that resulted in rewards and esteem and every other thing... Well the Joe Jetts are always with us, and they’re not really to blame, in my judgment at least. But that bastard who created that foolish accounting system who, so far as I know, has not been flayed alive, ought to be.

5. 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.

6. 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.”

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.
