Week 4: The counter

Social identity theory, and how "I drink there" becomes "I am one of the people who drinks there".

The minimal group studies are still astonishing. Divide people by a coin toss, by a preference between two painters they have never heard of, and they will allocate rewards to favour their own side — and will accept less for their own group in absolute terms if it widens the gap.

If that is all it takes, then a bar counter is enormously more than enough. The counter is the piece of furniture this lecture is about: a shared surface, a fixed number of places, everyone facing the same way, a member of staff standing opposite who mediates every arrival. It is a machine for turning attendance into membership.

Social identity theory gets us from I go there often to it is part of who I am, and it also gets us something less comfortable. If part of your self-concept is made of a group, you are motivated to keep that group favourably distinct. The warmth a regular feels toward the other regulars and the coolness they show a stranger are not two separate facts about the room. They are the same mechanism, seen from inside and outside.

That is the week 3 problem again, with a theory attached to it. A place cannot generate belonging without generating a boundary, and the friendlier the inside, the sharper the edge.
