When is the best treatment for pain more pain? When you're taking part in an experiment published by a Nobel prize winner and one of the leading lights in behavioural psychology, that is. The psychologist in question is Daniel Kahneman; the experiment described by the self-explanatory title of: When More Pain Is Preferred to Less: Adding a Better End. In the study, Kahneman and colleagues looked at the pain participants felt by asking them to put their hands in ice-cold water twice (one trial for each hand). In one trial, the water was at 14F (that's -10C) for 60 seconds. In the other trial the water was 14F for 60 seconds, but then rose slightly and gradually to about 15F by the end of an additional 30-second period.
