Outcome Bias
Judging a decision by its outcome rather than the quality of the decision-making process.
Why it works
Based on hindsight bias research (Baron & Hershey, 1988), people retrospectively judge decisions by results rather than information available at decision time. Successful outcomes make processes seem better while poor outcomes make good processes seem flawed. This results-focused evaluation creates systematic bias in learning and decision-making (Gino et al., 2010).
