A prejudice is a pre-judgment in favor of or against a person, a group, an event, an idea, or a thing. An action based on prejudgment is discrimination. A negative prejudgment is often called a stereotype. An action based on a stereotype is called bigotry. (What distinguishes this group of terms from all the others on these two pages is that there is no power relationship necessarily implied or expressed by “prejudice,” discrimination,” “stereotype” or “bigotry.”)
