Prospect Theory, as it was called, espoused that people are more likely to be dissatisfied with a loss than they are satisfied with a gain. In other words, people hate losing $100 more than they like winning $100. This, of course, means loss aversion is a greater motivator of buying decisions than potential gains. In fact, according to Kahneman, in certain situations, people are two to three times more motivated to make a change to avoid a loss than they are to achieve a gain.
