The ridiculous amount of activity by the untrained and uninformed on the stock markets seems to suggest that people could use a significantly higher amount of “zero sum” bias there. There are tons of people who would not peg their investment skill in the top 1%, who nonetheless think they have a good chance of making money in short term trades. There certainly seems to be the thinking that the stock market is a source of profits for one and all, regardless of investment skill and understanding.
This bias however is most prevalent in the idea that getting rich cannot possibly be a noble act, a point extensively addressed in Paul Graham’s essays.

I think that the main reason that people exhibit irrational stock market behavior is overconfidence bias.
Great points. I will link this comment in my next post.
