What is the definition of prejudice?

Prejudice is defined as a belief or opinion that is formed without sufficient knowledge, understanding, or justification. This definition emphasizes the irrationality and often automatic nature of such beliefs, highlighting that they are usually based on stereotypes rather than objective evidence. Prejudice typically involves negative attitudes toward individuals or groups because of their perceived characteristics, such as race, gender, religion, or nationality.

In the context of the provided options, the choice that best encapsulates this idea is the one that relates to beliefs formed without knowledge or reason. This option reflects how prejudice can arise from a lack of informed understanding and the tendency to make quick judgments about others based solely on preconceived notions.

Other options present alternative concepts. Favoring a group based on shared characteristics, for example, may relate more to group identity or preference but does not capture the inherent irrationality of prejudice. An objective assessment involves a fair evaluation based on facts, which stands in contrast to the subjective nature of prejudice. A justified opinion based on experience suggests that the opinion is formed through a rational process, which again contradicts the essence of prejudice, as such beliefs are often not based on informed experiences or logic.
