The findings of the psychologist Daniel Kahneman, winner of a Nobel economics prize, are devastating to the beliefs that financial high-fliers entertain about themselves. He discovered that their apparent success is a cognitive illusion. For example, he studied the results achieved by 25 wealth advisers across eight years. He found that the consistency of their performance was zero. "The results resembled what you would expect from a dice-rolling contest, not a game of skill." Those who received the biggest bonuses had simply got lucky.
Such results have been widely replicated. They show that traders and fund managers throughout Wall Street receive their massive remuneration for doing no better than would a chimpanzee flipping a coin. When Kahneman tried to point this out, they blanked him. "The illusion of skill … is deeply ingrained in their culture."
So much for the financial sector and its super-educated analysts. As for other kinds of business, you tell me. Is your boss possessed of judgment, vision and management skills superior to those of anyone else in the firm, or did he or she get there through bluff, bull**** and bullying?
