stereotyping

You view strangers as more similar than they are.

Outgroup homogeneity is the tendency to perceive members of other groups as uniform.

You see your own group as composed of diverse individuals with unique motivations, yet you perceive outsiders as a monolithic group with identical behaviors. This simplifies the social landscape but leads to inaccurate stereotypes.

We use stereotypes to categorize a world we do not take the time to learn.
