The debiasing effect of counterfactual mind-sets: Increasing the search for disconfirmatory information in group decisions
We hypothesized that the activation of a counterfactual mind-set minimizes decision errors resulting from the failure of groups to seek disconfirming information to test an initial hypothesis. To test this hypothesis, we conducted two experiments examining the decision making processes of groups. The task for both experiments was modeled after the Space Shuttle Challenger disaster, and groups had to actively seek disconfirmatory information to make a correct decision.
