Stereotypes, Prejudice, and Discrimination

The brain is a lazy filing system. Meeting every person as a total stranger would cost too much time and attention, so the mind sorts people into categories based on visible traits like age, race, or occupation, then borrows a ready-made description for anyone who fits. That shortcut is a stereotype: a generalized belief about what a group is like. It saves cognitive load by letting you skip gathering new information, but it costs accuracy, because it flattens real differences between individuals into one assumed profile and makes you notice anything that confirms it while ignoring anything that does not.

A stereotype, prejudice, and discrimination sit on a line from thought to feeling to action. The stereotype is the belief itself, stored in memory. Prejudice is the emotional charge attached to that belief, a negative feeling toward the group before you know the person. Discrimination is the behavior, treating someone worse or better because of their group membership. Because these are three separate stages, a person can hold a stereotype, even feel uneasy because of it, and still never discriminate; self-control and personal values can block the belief from turning into action. This is why measuring attitudes and measuring behavior give different answers.

The strongest documented way to weaken a stereotype is sustained contact between groups under genuinely equal status, meaning neither group holds more power, authority, or prestige during the interaction. Repeated equal-status contact replaces the vague category with real individual experience, which chips away at the generalized belief and the prejudice riding on it. Contact under unequal conditions, like a boss and a subordinate, tends not to work nearly as well, because the status difference itself can reinforce the very stereotype the contact was supposed to dissolve.
