Ask Americans “How similar are you to others?” and on average they will answer “Not very.” Ask the same question in reverse—“How similar are others to you?”—and their judgment of similarity increases noticeably.
The two answers should be exactly the same because the questions are, in essence, identical, but we manage to delude ourselves, just as we all claim to be above average or wholly unsusceptible to social influence. Time and time again, each one of us assumes that he or she stands out. What is it that makes us believe we’re more unique than everyone else?
