outgroup_homogeneity_bias
The tendency to perceive members of an outgroup as more similar to each other than members of one's own ingroup. People see their own group as diverse and varied, but view outsiders as interchangeable or 'all the same.' This asymmetry in perception fuels stereotyping and prejudice.
A manager from the marketing department says 'Engineers are all the same — they just want to code and hate meetings,' while recognizing that marketing team members each have distinct personalities, strengths, and communication styles.
A lifelong city dweller remarks, 'People in small towns all think the same way about politics — they're very traditional and resistant to change,' while readily describing their own urban neighborhood as a rich mix of progressives, moderates, artists, and pragmatists.
A sports fan says 'Fans of that rival team are all aggressive and obnoxious,' treating them as an undifferentiated bloc, while fully appreciating that fans of their own team range from passionate diehards to casual observers with completely different personalities.

We have more exposure to and interaction with ingroup members, giving us richer mental models of individual differences. Outgroup members are processed more categorically due to limited personal contact.
Increase meaningful personal contact with outgroup members to build individuated impressions. Actively seek out and note differences among outgroup members rather than similarities.
This bias is prevalent in intergroup conflicts, racial stereotyping, political polarization, and workplace departmental rivalries. It contributes to discrimination in hiring when decision-makers view minority candidates as interchangeable.
