Do you like sarcasm?

At Smithsonian Magazine Richard Chin writes about the pros and cons of sarcasm:

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.

...Sarcastic statements are sort of a true lie. You’re saying something you don’t literally mean, and the communication works as intended only if your listener gets that you’re insincere. Sarcasm has a two-faced quality: it’s both funny and mean. This dual nature has led to contradictory theories on why we use it.

Some language experts suggest sarcasm is used as a sort of gentler insult, a way to tone down criticism with indirectness and humor. “How do you keep this room so neat?” a parent might say to a child, instead of “This room is a sty.”

But others researchers have found that the mocking, smug, superior nature of sarcasm is perceived as more hurtful than a plain-spoken criticism. The Greek root for sarcasm, sarkazein, means to tear flesh like dogs.
