In what way is scapegoating different from realistic conflict as a source of prejudice, discrimination, and inter-group conflict?

What will be an ideal response?

Answer: Realistic conflict theory posits that prejudice, discrimination, and intergroup conflict arise when there is political or economic competition for scarce resources. In some cases there really is a group with which our group is in competition (e.g., newly arrived immigrants competing with native citizens for scarce jobs). In other cases, there really is no "other group." When it is difficult to identify the real source of our frustration, or when it is difficult to confront economic forces or government policy, in-groups often "invent" out-groups to blame for their situation. This is known as scapegoating.
