Nobody knows us better than our family and friends, right? Who else could predict how we’ll react to good and bad news, or whether to pick the pie or ice cream for dessert?
Facebook, for one. Researchers at the University of Cambridge and Stanford University studied how Facebook Likes matched up with people’s own answers on personality tests, as well as those of their close family and friends. With enough Likes of objects, brands, people, music or books, the computer was better at predicting a person’s personality than most of the people closest to them—with the exception of spouses. (They still know us best, it seems.)
