Familiarity, it turns out, breeds affection. The “mere exposure effect” is the term for the fact that repeated exposure makes you like music, faces—even nonsense syllables—better. The more often you see a person, the more intelligent and attractive you’ll find that person. I’d noticed this about myself. Even when I don’t take an immediate liking to someone, I tend to like him or her better the more often we see each other. And at the same time, the more I show up, the more that person likes me.
