Definition
Loss aversion is a strong preference people have for avoiding losses rather than making gains. This was first identified by the psychologists Amos Tversky and Daniel Kahneman. They found that people have a loss aversion ratio of between 1.5 and 2.5. This means that for people willing to risk a loss of £100, most people would require a potential gain of between £150 to £250. As a result loss aversion is a strong factor in preventing people changing from the status quo or taking even small risks.
