Assholes were made to perform certain tasks while their brains were being scanned. In one task, the subjects were asked to imagine lying on a beach on a tropical island. In other tasks, the assholes were asked to imagine something good about a member of their family, any accomplishment they could be proud of, a waitress they were nice to, and something that went wrong that they were willing to accept responsibility for. They failed every task spectacularly. As their brains were thus engaged, a certain part of the posterior corpus rumpus, known as the temporal anal cortex, lit up like a Christmas tree.
