The friendship paradox is the empirical observation that your friends
have more friends than you do. Now network scientists say your friends
are probably wealthier and happier, too.
Back in 1991, the sociologist Scott Feld made a surprising discovery while studying the properties of social networks. Feld calculated the average number of friends that a person in the network has and compared this to the average number of friends that these friends had.
Against all expectations it turned out that the second number is always bigger than the first. Or in other words, your friends have more friends than you do.
Researchers have since observed the so-called friendship paradox in a wide variety of situations. On Facebook, your friends will have more friends than you have. On Twitter, your followers will have more followers than you do. And in real life, your sexual partners will have had more partners than you’ve had. At least, on average.
I always figured that it was because my friends are friendlier, wittier, and more fun than I am.
