The Science of Sarcasm? Yeah, Right

In an episode of “The Simpsons,” mad scientist Professor Frink demonstrates his latest creation: a sarcasm detector.

“Sarcasm detector? That’s a really useful invention,” says another character, the Comic Book Guy, causing the machine to explode.

Actually, scientists are finding that the ability to detect sarcasm really is useful. For the past 20 years, researchers from linguists to psychologists to neurologists have been studying our ability to perceive snarky remarks and gaining new insights into how the mind works. Studies have shown that exposure to sarcasm enhances creative problem solving, for instance. Children understand and use sarcasm by the time they get to kindergarten. An inability to understand sarcasm may be an early warning sign of brain disease.

Sarcasm detection is an essential skill if one is going to function in a modern society dripping with irony. “Our culture in particular is permeated with sarcasm,” says Katherine Rankin, a neuropsychologist at the University of California at San Francisco. “People who don’t understand sarcasm are immediately noticed. They’re not getting it. They’re not socially adept.”

Sarcasm seems to exercise the brain more than sincere statements do. Scientists who have monitored the electrical activity of the brains of test subjects exposed to sarcastic statements have found that brains have to work harder to understand sarcasm.

That extra work may make our brains sharper, according to another study. College students in Israel listened to complaints to a cellphone company’s customer service line. The students were better able to solve problems creatively when the complaints were sarcastic as opposed to just plain angry. Sarcasm “appears to stimulate complex thinking and to attenuate the otherwise negative effects of anger,” according to the study authors.
