- Abstract
- In group decision-making, people take insufficient account of other’s information. We hypothesize that this can be explained by an ownership bias that would especially occur in competition, rather than in cooperation. In a two-phase decision making situation, people reach an initial decision and then they evaluated the value of their own information and other’s consistent and inconsistent information under different conditions of goal interdependence (cooperation or competition). Finally, then had to reach a final decision regarding a road accident. Results showed an ownership bias in information value, stronger in competition than in cooperation. Moreover, decision quality was lower in competition than in cooperation, an effect mediated by the ownership bias, beyond the preference effect.
