Locked into gambling: anticipatory regret as a motivator for playing the National Lottery.

Abstract

Four hundred and eighty-five people were asked about their intentions to play the National Lottery in England a week prior to the introduction of a new midweek draw. We predicted that those people who played the Saturday game with a regular set of numbers would be more inclined to play the new midweek game than those who had not established a routine of using the same set of numbers. We further predicted that their motivation to play would derive from a feeling of 'anticipatory regret'--a sense that they would find it intolerable to discover their regular numbers had been drawn when they hadn't purchased a ticket. Results supported both of these predictions, and an interpretation of the data is given in terms of the circumstances most likely to trigger such counterfactual reasoning.
