Loss Aversion
- Categories
- Decision Making
Losses loom larger than equivalent gains, roughly twice as much. Choices are made relative to a reference point, and the pain of losing outweighs the pleasure of gaining the same amount.
Why it Matters
Loss aversion shapes risk-taking, the status quo bias, and the endowment effect, and explains behavior that pure expected-value reasoning cannot. It makes people risk-averse for gains and risk-seeking to avoid losses.
Signals
- Reluctance to give up something already held.
- Demanding far more to sell than one would pay to buy.
- Clinging to losing positions to avoid realizing a loss.
Benefits
Anticipating it improves how changes, prices, and incentives are framed, and explains resistance to change.
Risks
Holding losers too long, avoiding good bets framed as risks, and overvaluing the status quo.
Tensions
Caution about losses is often adaptive, but it produces inconsistent, reference-dependent choices that violate rational value.
Examples
Refusing a 50/50 bet to win $150 or lose $100; valuing an owned item far above its market price (the endowment effect).
