Losses Hurt More
Why losing £100 feels worse than winning £100 feels good.
- The Idea
Loss aversion
Losing something tends to feel more powerful than gaining the same thing. Psychologists call this loss aversion.
- The Bet
Heads or tails
Offered a coin flip — win £150 on heads, lose £100 on tails — most people refuse, even though the bet favours them.
- The Ratio
Roughly twice as strong
Studies often estimate losses feel about twice as strong as equal gains, though the exact figure varies.
