Insular
adjective /ˈɪn.sjʊ.lər/ — Narrow-minded; uninterested in ideas or people from outside one's own experience.
Definition
Relating to an island; ignorant of or uninterested in cultures, ideas, or peoples outside one's own experience. Insular thinking is the thinking of a person who has never left the island of their own assumptions.
Beyond the definition
Insularity protects. It is not always comfortable to have your assumptions challenged, your knowledge expanded, your certainty disturbed. But protection becomes limitation when it closes the door entirely.
Origin & history
Latin: 'insula' (island). Originally literal — relating to islands. The metaphorical sense developed from the idea of the island as a self-contained world, cut off from the continent of wider experience.
