Prejudice is an affective feeling towards a person or group member based often on that person's group membership (tribal behavior). The word is often used to refer to preconceived, usually unfavourable, feelings towards people or a person because of their political affiliation, 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.
Prejudice can also be classified as a reaction to a race and/or culture based purely on experience.
Religious bigotry has been evidenced throughout history; Jews have often been the target. Political bigotry exists most commonly under totalitarian regimes headed by people with extremist positions. Class bigotry, in addition to the obvious caste system, is often discernible in labour - management conflicts and in the attitude of one national group to another.
Bigotry is an intolerant, obstinate, and unthinking attachment to one's views, party, or religion. It is heedless of truth, flouts the obligation to treat one's fellow man with sympathy and love, and is highly disruptive of social unity. Bigotry involves powerful emotions, thus is easy to incite. It stems from various causes, often begun at home, developed in school, and maintained by the media and governmental laws.
