The Washington Post sited a study showing that sarcasm helped engineering students solve more complex problems:
a new study in the Journal of Applied Psychology (hat tip to the BPS Occupational Digest blog) that looks at how various emotions that people observe prompt them to respond. The study asked 375 engineering students to imagine they were a customer service agent, and then listen to a conversation between a customer and a representative. Some of the discussions were neutral; others were openly hostile. The students were then given straightforward analytic problems or creative questions to solve.
The students who had overheard the angry conversation did better at the analytic problems than their peers who heard nothing but nice talk
But just because the students worked harder doesn’t mean they worked smarter. In a similar study by the psychologists, students listened to conversations where the customer was criticized with tough sarcasm. Despite also listening to a form of anger — albeit laced with humor this time — these students performed better on the creative problems. The study also showed that students exposed to sarcasm performed better on problems that required more “cognitive complexity,” or the ability to look at issues from more than one angle, than those that didn’t hear such comments.
