At least this is what shows a recent study. The Journal of Organizational Behavior and Human Decision Processes published a study that shows that sarcasm has a positive effect on one’s creativity.
3 experiments were conducted where people altered between saying something sarcastic and something honest to other people. Then, the experiment’s subjects had to go through a creativity test and the people who either expressed themselves sarcastically or heard others do it were the ones who performed better in the tests.
This research shows a fact that can be easily understood by common sense. Being in contact with sarcasm makes your brain work more in order to interpret it, and work so in a creative way. This is what is called the structure of the sass.
In the process of understanding sarcasm, or transversing the distance between literal meaning and metaphorical use, the brain needs to perform abstract thinking, which in turn sets off the creative thinking process.
The author of the study, Li Huang, told the Huffington Post in an interview that this is the psychological distance needed to be overcome, and this process is equally beneficial for the person talking and for the recipient.
