Belonging

We favour people we see as one of us, and we choose brands that show which group we are part of: a team, a town, a nation, a tribe.

Belonging: where it comes from

Henri Tajfel split schoolboys into groups on a trivial basis, such as which of two painters' work they preferred, and found that they still favoured their own group when sharing out rewards (Tajfel, 1970). Robert Cialdini later added this sense of shared identity to his principles of influence, as unity.

In ads it shows up as appeals to a nation, a team, a town, a generation or a subculture, and in brands people use to show which group they belong to.
