Prejudice, or bigotry, is an affective feeling towards a person or group member based solely on that person's group membership. The word is often used to refer to preconceived, usually unfavorable, feelings towards people or a person because of their sex, gender, beliefs, values, social class, age, disability, religion, sexuality, race/ethnicity, language, nationality, beauty, occupation, education, criminality, sport team affiliation or other personal characteristics. In this case, it refers to a positive or negative evaluation of another person based on that person's perceived group membership.
Prejudice can also refer to unfounded or pigeonholed beliefs and it may include "any unreasonable attitude that is unusually resistant to rational influence". Gordon Allport defined prejudice as a "feeling, favorable or unfavorable, toward a person or thing, prior to, or not based on, actual experience". For the evolutionary psychology perspective, see Prejudice from an evolutionary perspective. Auestad (2015) defines prejudice as characterized by 'symbolic transfer', transfer of a value-laden meaning content onto a socially formed category and then on to individuals who are taken to belong to that category, resistance to change, and overgeneralization.
