In the 1990s, the Nobel laureate Daniel Kahneman ran a study on colonoscopy patients. Some had the instrument withdrawn quickly at the end of the procedure, producing a sharp final moment of discomfort. Others had it withdrawn more slowly, extending the procedure but ending on a milder sensation. The latter group rated the overall experience as less unpleasant: They had more total discomfort, and they remembered it better.
