Stereotypes are defined as widely held but fixed and oversimplified images or ideas of a particular type of person or thing.

For example, elders are stereotyped as high warmth and low competence across cultures and these mixed stereotypes elicit pity/sympathy and passive harm (e.g., neglect). Whereas some elders are stereotyped low in warmth and competence and these stereotypes elicit contempt/disgust and active harm (e.g., physical abuse). Read more here.
