In an article in Discover Magazine, Robert Provine, a professor of psychology and neuroscience at the University of Maryland, asserts that the root of human laughter doesn’t lie in humor but in social interaction. We laugh to bond.
Previous studies of laughter had assumed that laughing and humor were inextricably linked, but Provine’s early research suggested that the connection was only an occasional one. As his research progressed, Provine began to suspect that laughter was in fact about something else—not humor or gags or incongruity but our social interactions. He found support for this assumption in a study that had already been conducted, one analyzing people’s laughing patterns in social and solitary contexts. “You’re 30 times more likely to laugh when you’re with other people than you are when you’re alone—if you don’t count simulated social environments like laugh tracks on television,” Provine says. Think how rarely you’ll laugh out loud at a funny passage in a book but how quick you’ll be to give a friendly laugh when greeting an old acquaintance. Laughing is not an instinctive physical response to humor, the way a flinch is a response to pain or a shiver to cold. Humor is crafted to exploit a form of instinctive social bonding.
As an added bonus, the article’s author also reproduces the joke that an international survey determined was the world’s funniest joke:
A couple of New Jersey hunters are out in the woods when one of them falls to the ground. He doesn’t seem to be breathing; his eyes are rolled back in his head. The other guy whips out his cell phone and calls the emergency service. He gasps to the operator: “My friend is dead! What can I do?” The operator says: “Take it easy. I can help. First, let’s make sure he’s dead.” There is silence, then a shot is heard. The guy’s voice comes back on the line. He says, “OK, now what?”
