Introduce study --> link to question:
Tajfel found that when people are randomly assigned to a group - either by the flip of a coin, the drawing of a coin, the drawing of a number from a hat, or by preference for a previously unknown artist - they see themselves as being similar in attitude and behaviour + automatically think of that group as their in-group and all others as an out-group, therefore a bond is formed among group members, even if they did not know each other before their assignment to the group.
To demonstrate the minimal group paradigm in creating in group bias
Schoolboys from Bristol were randomly allocated into groups (though they were told it was off a basis for a preference of artwork for Kandinsky or Klee).
Told they were participating in a decision making experiment
They individually assigned points based off a matrix to their group or another group.
They were allowed no face to face contact or communication.
Boys tended to favour ingroup members over outgroup members (ingroup favouritism)
Boys maximised differences between groups (category accentuation effect), even if it was potentially disadvantageous to their own group
The idea of being in a group is enough to induce own group bias (minimal group paradigm)
Unusual task in an artificial environment --> Lacks ecological validity
Might have been influenced by demand characteristics of the situation and acted in the way that they thought was expected of them.
Tajfel"s study has reduced this complex psychological phenomenon down to a very simple level, focusing just on minimal groups and performance of a simple experimental task.
Participants can"t be generalized to the wider population
Same age range & Country
Participants were told it was a study on decision making, when it was actually about group bias
Participants did not give informed consent as they did not know the true aim of the study
Connection of study to question
This study supports SIT because the participants showed ingroup favouritism and category accentuation effect, which is an intergroup behaviour and concept of SIT
