Despite popular consensus that "revenge is sweet," years of experimental research have suggested otherwise, finding that revenge is seldom as satisfying as we anticipate and often leaves the avenger less happy in the long run. Now, new research from Washington University in St. Louis is adding a twist to the science of revenge, showing that our love-hate relationship with this dark desire is indeed a mixed bag, making us feel both good and bad, for reasons we might not expect. Its findings are based on three experiments in which about 200 people in each experiment were asked to fill out online questionnaires rating the intensity of moods and emotions triggered by their reading of brief news accounts, including one that described the killing of Osama bin Laden by U.S. forces as a retaliation for the 9/11 terrorist attacks. The experiments were designed to explore whether people are right in thinking that revenge has the potential to make them feel good, despite recent research that suggests otherwise. https://www.sciencedaily.com/releases/2016/06/160629130459.htm?
