"Do you believe in magic?", an interesting read.

If the tendency to think magically were no more than self-defeating superstition, then over the pitiless history of human evolution it should have all but disappeared in intellectually mature adults.

Yet in a series of experiments published last summer, psychologists at Princeton and Harvard showed how easy it was to elicit magical thinking in well-educated young adults. In one instance, the researchers had participants watch a blindfolded person play an arcade basketball game, and visualize success for the player. The game, unknown to the subjects, was rigged: the shooter could see through the blindfold, had practiced extensively and made most of the shots.

On questionnaires, the spectators said later that they had probably had some role in the shooter’s success. A comparison group of participants, who had been instructed to visualize the player lifting dumbbells, was far less likely to claim such credit.
