Why do people reject unfair offers?

Many people dislike an unequal split and feel a strong negative emotion when treated unfairly. In the ultimatum game, low offers are often rejected even though the responder then gets nothing, and 30 to 40 per cent still reject unfair offers when only they lose by doing so.

What the report found

  1. People turn down free money to resist unfairness. In the ultimatum game, a responder who rejects a low offer gets nothing, yet low offers are often rejected. No group studied behaved as pure self-interest predicts.
  2. Unfairness is felt, not just calculated. Unfair offers activated a brain region linked to disgust and distress, and between 30 and 40 per cent of people still rejected unfair offers when doing so hurt only themselves.
  3. The same price can be fair or unfair. Raising the price of snow shovels after a storm was judged unfair by 82 per cent of people. A 7 per cent pay cut was judged unfair by 62 per cent, but a pay rise of 5 per cent during 12 per cent inflation, a similar loss, by only 22 per cent.
  4. Unfair pay costs output. In a field experiment, a wage cut reduced output by more than 20 per cent, while an equal raise added nothing. Learning they earned less than colleagues lowered workers' satisfaction.
  5. Fairness in process softens bad outcomes. People accept unwelcome decisions far more readily when the process feels fair, and the threat of punishment for unfair behaviour keeps groups cooperating.

For anyone who has walked away from a deal that felt wrong, and anyone who sets prices, pay or rules for others.

How we work

Human Forces reports explain one deep human need and the many effects that grow from it. Every claim is graded Established, Emerging or Untested. Where researchers disagree, as they do on whether animals have a sense of fairness, both sides are set out before we say where we stand.
