There is an interesting phenomenon called "the Firehouse Effect" that is similar but on a group level.

The idea is that if you take a group of humans and isolate them, they will begin to believe wilder and wilder ideas and communicate those ideas amongst themselves. This happens because the group is not routinely "reconciling" with broader society which in turn is slower to adopt new ideas.
