Loss aversion is a cognitive
bias that describes why, for individuals, the pain of losing is psychologically twice as powerful as the pleasure of gaining. The
loss felt from money, or any other valuable object, can feel worse than gaining that same thing.In behavioural economics,
loss aversion refers to people's preferences to avoid losing compared to gaining the equivalent amount. For
example, if somebody gave us a £300 bottle of wine, we may gain a small amount of happiness (utility).
