Learn English – Word for “self-reinforcing [beliefs]”


I want to describe a group of people who are experiencing a kind of “echo chamber” effect, reinforcing each other’s beliefs, e.g.:

The clique tends to have a ____ culture: once someone suggests an idea, the whole group clings on to it.

I’m gravitating towards self-reinforcing and self-feeding, but these both sound hopelessly off the mark.

Reading the Wikipedia article on Echo chamber (media), I found this line:

Another emerging term for this echoing and homogenizing effect on the Internet within social communities is cultural tribalism.


noun 1.1 derogatory The behaviour and attitudes that stem from strong loyalty to one's own tribe or social group
"a society motivated by cultural tribalism"
