Much of the earlier interest in gambling behaviour has been centred on the traditional theories of human decision-making, where decisions are portrayed as choices among bets. This led to a tradition of studying decision-making in experiments on betting. In this title, originally published in 1988, the author argues that betting behaviour should not be used as a typical example of human decision-making upon which a general psychological theory could be founded, and that these traditional views can in no way account for the gambling behaviour reported in this book.
