Social Identity Theory: You Can’t Sit with Us
A dummy’s guide to the psychology of racism and xenophobia
Racism and xenophobia have had an insidious influence on human society since time immemorial. Has there ever been a time when one group or another were not facing prejudice and injustice from another group? Unlikely.
Do we have a predisposition as a species to hold prejudiced views against those who are different to us and to treat them worse than we treat those we consider similar to us? Many people would respond with the knee-jerk ‘of course not! I treat all people equally’. In fact, such a response may be less than helpful as it shows a blithe ignorance of the underlying predisposition humans may have to prejudice and, therefore, cheats us out of recognising and addressing this issue. Would it be helpful to say in response to the question, ‘do humans have a tendency to catch colds?’, ‘no of course not!’? Clearly not as if we believed such a thing we would not take the necessary precautions to prevent colds and to recover from them. It is much the same story with prejudice.
So, what is the evidence here? Let’s start at the basics. A key figure who you should be aware of as a pioneer in the psychology of racism is Henry Tajfel. As a Polish Jew who was at one point captured by the German army, and held as a prisoner of war, he was all too familiar with witnessing prejudice first hand. There is little mystery about Tajfel’s motivations in studying prejudice in social psychology.
One seminal experiment of Tajfel’s demonstrated a rather disturbing characteristic of human behaviour. A group of school boys were recruited to take part in an experiment where they were shown two pictures, one by the artist Klee and one by Kandinsky. The boys were asked independently which picture they preferred and then grouped by their choice. This was followed by an activity in which the boys were required to allocate money to their own group and the other group respectively. It was found that, despite the arbitrary nature of their groupings, school boys were inclined to give the other group less money than their own, even when it was to the detriment of their own group. For example, a boy would rather give his own group £4 and the other £3 than giving both £5. This experiment has been replicated a number of times, sometimes with nothing deciding the group allocation other than a totally random coin toss and, still, the same result.
Tajfel’s key theory which arose from this research was the idea of Social Identity Theory. This theory suggests that all persons are inclined to favour members of their in-group as compared to an out-group
This experiment is, of course, not without flaws. Firstly, the age of participants may have influenced the findings – do we become less prejudiced and susceptible to bias as we grow older (or more so)? Of course, just using boys is far from ideal, perhaps women represent our kinder nature and are more open minded to other groups?
This study is only the tip of the ice-berg when it comes to the social psychology of racism but certainly provides some food for thought. If prejudice really does permeate our psyches in such a fundamental way, then the need for active civil rights work and constant work to ensure equality in our society is vital.
