Experiments show that people who were forced to make choices among a range of consumer goods (e.g., color of T-shirt, type of scented candle, brand of shampoo, type of candy, and, yes, even type of sock) performed worse than those who were presented with only one option on tests of everything from physical stamina to persistence to problem-solving. The subjects who were confronted with multiple choices also procrastinated more in other areas of their life later on in the day.
