Discrimination in minimal groups: A case of the Butler did it or Murder on the Orient Express?

Prof. Dr. Russell Spears Social Psychology

Almost 50 years ago Henri Tajfel demonstrated mere categorization into (minimal) groups on a trivial basis (e.g., a coin toss) was sufficient to produce intergroup discrimination. This effect has had a profound effect on our understanding of the power ofgroups that influenced evolutionary and economic theories as well as social psychology.
However finding the true explanation turns out to be likehunting for the culprit in a never- ending Agatha Christie murder mystery. I provide a historical journey through the various explanations not least Tajfel’s preferred “social identity” account.

Despite trying to rule out self-interest, this keeps returning like the proverbial mummy that won’t die and I present some recent research suggesting that the first idea, dismissed by Tajfel has also risen from the dead. The true culprit is then revealed.
