Like so many social and gender traits, men’s dislike of shopping can also be explained by evolutionary psychology. Daniel Kruger , an evolutionary psychologist at the University of Michigan1 explains the difference in attitude towards shopping on the basis of the difference between two primary systems of acquiring food in primitive times – hunting and gathering. In the dawn of civilization, men were primarily hunters – when they spotted a deer or a fox, the primary instinct was to shoot it, before it got away.
