University of Chicago professor Nicholas Epley has found that when you’re dealing with strangers, you correctly detect their thoughts and feelings only 20 percent of the time. (Random chance accuracy is 5 percent.) Now, of course, you’re better when dealing with people you know . . . but not by much. With close friends you hit 30 percent, and married couples peak at 35 percent. In school that’s an F. Actually, it’s probably closer to a G. Whatever you think is going on in your spouse’s head, two-thirds of the time, you’re wrong.
