Loss Aversion
Losses loom larger
What it means
People often give a prospective loss more psychological weight than a comparable gain. Preserving what one has can feel more urgent than pursuing an equally valuable improvement. The strength varies; it is not a universal mathematical constant.
Typical uses
Property, investing, employment, negotiations, public benefits, business decisions, and resistance to policy changes.
