Outgroup Homogeneity Bias – when ‘they’re all the same,’ but ‘we’re all unique’

Electric editorial collage illustrating Outgroup Homogeneity Bias

Do you feel like your group is diverse, but other groups are all the same? That’s Outgroup Homogeneity Bias – the tendency to see members of your own group as individuals, while viewing outsiders as uniform.

Where it can show up


- National stereotypes – ‘All French people love wine’ or ‘All Germans are punctual,’ when in reality, individuals vary.
- Politics – supporters of the other party seem ‘all equally misguided,’ while your side consists of ‘independent thinkers.’
- Work & competition – your company has diverse talents, but competitors all seem identical.

A practical countermeasure


- Replace generalizations with facts – before saying ‘they’re all like that,’ ask yourself if you have real evidence.
- Put yourself in their shoes – would you like being stereotyped the same way?
- Engage with different people – personal experience is the best way to break stereotypes.
