Alternate Sources of Prejudice

While most people believe that prejudice stems from psychological sources, some other possible explanations have been identified. Among these are biological sources, social sources, and historic and cultural sources. Prejudices, stereotypes, and social-isms all are "multidetermined", meaning they cannot be traced back to one distinct cause. However, exploring all of the possible alternative sources of prejudice can help one better understand why it exists and maybe provide some answers as to what can be done to eliminate prejudice and discrimination.


Biological Sources

Some scientists believe that prejudice can be inborn. They believe that some people are just naturally more prejudiced than others, regardless of how they were raised, educated, and interacted socially. One documented theory is the Genetic Similarity Theory of sociobiologist Philippe Rushton. This theory states that prejudice towards others is a result of evolution. People are programmed to bias against others unlike themselves based on "survival of the fittest". They want only their genes to be reproduced and passed on, thus wanting them to suppress others who are not in the "in-group". This primarily deals with racial and ethnic prejudices.

While the biological explanations of prejudice formation are controversial, they are based in other accepted scientific theories, such as evolution. Still, while they may seem to somewhat explain why prejudice exists in some people and not in others, biology has not been proven to be a good predictor of prejudicial behavior.


Social Sources

There are a few social explanations for the existence of widespread prejudice. One of these is based in social norms. Social norms are what the specific society either officially or unofficially agrees is "normal" for everyone; they are often unspoken laws by which we all abide. For example, a person wouldn't usually wear two totally different shoes or go yelling through a library, it would be considered "weird" because it broke the social norms we all live by. Prejudice works the same way.

Often whole societies can be prejudiced against outsiders of any type. Being prejudice against, having dislike and/or distrust for, and mistreating anyone seen as different might be a social norm; something that a member of the society does just because it's what they're "supposed to do".

Another social theory of prejudice formation is called Realistic Conflict Theory. This theory is based on the idea that in some cases, different groups are in competition for limited resources, such as food, water, and money. They then band together, based on their ethnic heritage, to take what they believe should be theirs. As of late this has shown itself in the "ethnic cleansing" happening in Eastern Europe.


Historical and Cultural Sources

Some theorists choose to look at prejudice from a historical perspective. For example, prejudice against blacks in the United States has its historical roots in slavery and the Civil War. Often history is the case in areas that new people have moved into an area, and the natives have felt threatened or were downright suppressed. This includes such places as South Africa, Northern Ireland, and the former Yugoslavia. Historical prejudice can be the result of direct aggression, or just a cultural misunderstanding. It is quite easy for a cultural misunderstanding to occur, when two very different countries come in contact with one another, with differing languages, beliefs, values, wants, and needs. These misunderstandings can snowball, and over time create a rift huge enough to cause widespread prejudice to occur.
