The inability to envision a certain kind of person doing a certain kind of thing because you've never seen someone who looks like him do it before is not just a vice. It's a luxury. What begins as a failure of the imagination ends as a market inefficiency: when you rule out an entire class of people from doing a job simply by their appearance, you are less likely to find the best person for the job.

Why pay $20 million to Harrison Ford? I dont even understand that. They think they have to do it... If someone puts a price on himself, that suggests he is irreplaceable, then he better find somewhere else to work.

That was how a Salomon bond trader thought: He forgot whatever it was that he wanted to do for a minute and put his finger on the pulse of the market. If the market felt fidgety, if people were scared or desperate, he herded them like sheep into a corner, then made them pay for their uncertainty. He sat on the market until it puked gold coins. Then he worried about what he wanted to do.

There was some sinister activity, but I think by and by it was people being incentivised to do the wrong thing.
