In reality, there are many groups of people and many situations. However, here is a simplified way of looking at the dynamics and effects of prejudice and discrimination. Prejudice divides people into inferior and superior groups on the basis of stereotypes as described above.
Discrimination then limits opportunity and changes exposure to risk as follows.
Or, a Jewish person might get turned down for a job promotion in favour of a non-Jewish person. Furthermore, prejudice serves to expose people to different social risks . For example, a police officer might keep a closer watch on a black teenager than a white teenager hanging out in front of a store. Or, women are more likely to be sexually harrassed by employers than men. One of the worst effects of prejudices is that they become self-fulfilling prophecies .
