Answer:
Prejudice
Step-by-step explanation:
In psychology, the term prejudice refers to an unjustified or incorrect attitude (usually negative) towards an individual based solely on the individual's membership of a social group. Prejudice usually involves negative feelings about a person or group of persons that belong to a certain social group. When the person who is having the prejudice ACTS on it, we say that the person is discriminating.
Thus, we can say that the main difference between discrimination and prejudices is that prejudices refer to negative feelings that can lead to discrimination acts.
In this example, Sean believes that all college athletes are egotistical and self-centered, these negative feelings are reflected in his refusal to support or watch any college athletic events. Sean is showing a negative attitude based on the membership of a social group (in this case: college athletes), therefore we can says his attitude illustrates Prejudice.
