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. 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 is “a sharp, bitter, or cutting expression or remark; a bitter jibe or taunt”, usually conveyed through irony or understatement. Some language experts suggest sarcasm is used as a sort of gentler insult, a way to tone down criticism with indirectness and humor.
