we don’t perceive circumstances objectively. We pick out those bits of data that make us feel good because they confirm our prejudices. As Andrew Lo of M.I.T. has demonstrated, if stock traders make a series of apparently good picks, the dopamine released into their brains creates a stupor that causes them to underperceive danger ahead.
Biases abound. People who’ve been told to think of a high number will subsequently bid much more for an item than people who’ve been told to think of a low number. As Jonah Lehrer writes in his forthcoming book, “How We Decide,” there are certain circumstances (often when there are many options) in which gut instincts lead to the best decisions, while there are other circumstances (sometimes when there are a few options) when calm deliberation is best.
Most important, people seek relationships more than money. If behaving a certain way helps a stock trader or a regulator fit in with his crowd, he’s likely to keep doing it without too much rigorous self-examination.
