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

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.
