So, why would anybody use verbal irony and sarcasm, if we risk not only being misunderstood, but possibly worse? Newer science says that irony is actually good for you! It can help regulate emotions, foster creativity, and manage social relationships. This lecture will discuss science related to sarcasm, from examples and prevalence of sarcasm in the world around us, what happens in your brain when you encounter it, and how we can use this communicative superpower to our advantage.
