Try to follow this next bit. It's very illuminating.
“To create or decode sarcasm, both the expressers and recipients of sarcasm need to overcome the contradiction (i.e., psychological distance) between the literal and actual meanings of the sarcastic expressions. This is a process that activates and is facilitated by abstraction, which in turn promotes creative thinking,” Francesca Gino, one of the major players in the study, told the Harvard Gazette via email. Right. Makes sense.
So what does this mean for sarcastic people and their victims out there in the world, ultimately? I don't know. And frankly I don't care. Tomorrow, there will probably be "new data" released that proves sarcasm contains airborne carcinogens and also that dark chocolate decreases the rate of feline diabetes. At any rate, if you want to read the rest of the study, you can do so here, if you want. Doesn't really matter, we are all going to die one day, anyway.
