a psychological attitude of prejudice and hostility towards something without sufficient grounds for such an attitude. The object of prejudice is usually people or communities that differ sharply from their own. Prejudice implies a categorical assessment, is not based on facts and experience, but is learned from unreliable sources. Most often, they mean ideas shared by a fairly large number of people. The origin and mechanisms of prejudice are studied in the theory of prejudice (see Theory of prejudice in Chapter 1.8. Key Psychological Concepts in Social Psychology)
