In-group favoritism is preferring, trusting, or rewarding people seen as part of your own group.


How it operates

Shared identity triggers warmth, reciprocity, and assumptions of competence that make standards uneven.

  3. Incident 03

What to watch for

Ask: Would I judge this person the same way if they were not one of us?

Recommended action

Use blind reviews, structured rubrics, and decision panels with diverse membership.
