the Psychology of Human Misjudgment
The Psychology of Human Misjudgment by Charlie Munger
“The elementary part of psychology ‑ the psychology of misjudgment, as I call it ‑ is a terribly important thing to learn. There are about 20 little principles. And they interact, so it gets slightly complicated. But the guts of it is unbelievably important. Terribly smart people make totally bonkers mistakes by failing to pay heed to it. In fact, I’ve done it several times during the last two or three years in a very important way. You never get totally over making silly mistakes. There’s another saying that comes from Pascal which I’ve always considered one of the really accurate observations in the history of thought. Pascal said in essence, ‘The mind of man at one and the same time is both the glory and the shame of the universe.'” — Charlie Munger
Charlie Munger’s standard causes of Human Misjudgement is truly great stuff, and something I wish everyone had the privilege to get in touch with.
The audio file below contains the often referred to speech by Charlie Munger on the psychology of human misjudgment given to an audience at Harvard University back in 1995. In his speech, Charlie talks about some of the different kinds of human misjudgments that he has encountered through his life.
