This is a little different from other pieces we have seen on the markets. Now we drop back and think about our own foibles, in this article from Daniel Kahneman, Nobel laureate in economics, who got his for writing about the psychology of investing. He showed not just that we are irrational human beings, but that we are predictably irrational. And that extends to confidence. Not long, but it makes me want to get his book, which will come out soon.
