Using the knowledge

Losing a sum of money tends to feel worse than finding the same sum feels good. Behavioural economists call this loss aversion.

It helps explain why people hold losing investments, avoid switching providers, and respond so strongly to “limited time” offers.

The basic idea

Research in prospect theory found that people evaluate outcomes as gains or losses relative to a reference point, and that losses weigh more heavily. The exact size of the effect varies by context and has been debated, but the general pattern is widely observed.

Framing matters

The same choice described as avoiding a loss rather than achieving a gain can change behaviour. Marketers frame offers as “don’t miss out” for this reason.

The endowment effect

People often value things more once they own them. Free trials and “try before you buy” policies take advantage of this — giving up something you already have feels like a loss.

Status quo bias

Switching insurance, energy, or bank accounts involves potential losses, so many people stay put even when switching would save money.

Using the knowledge

Recognising loss aversion helps you evaluate decisions more evenly: ask what you would choose if you were starting fresh, without the current option as a reference point.
