"People seemed to have two different selves— an experiencing self who endures every moment equally and a remembering self who gives almost all the weight of judgment afterward to two single points in time, the worst moment and the last one. The remembering self seems to stick to the Peak-End rule even when the ending is an anomaly. Just a few minutes without pain at the end of their medical procedure dramatically reduced patients' overall pain ratings even after they'd experienced more than half an hour of high level of pain. "That wasn't so terrible," they'd reported afterward. A bad ending skewed the pain scores upward just as dramatically."
