What does insularity mean?
Insularity describes the condition of being separated from or unwilling to engage with the wider world. Its common modern meaning is critical: it refers to narrow-mindedness, parochialism, or a preference for one’s own community, culture, and perspective while ignoring or excluding others. A person, organization, or society described as insular may be socially or politically self-contained, resistant to outside influence, or simply unaware of perspectives unlike its own. The word can also have a literal geographical sense, referring to the condition of being an island or isolated territory. In everyday discussion, “cultural insularity” and “political insularity” are especially common. The term is often used in debates about immigration, nationalism, education, business, and international relations, where it highlights either physical separation or a psychological boundary between one group and another. Unlike isolationism, which usually concerns a deliberate foreign policy, insularity can apply broadly to any restricted outlook.

Insularity begins with a map, but it can also become a state of mind: the belief that the world ends at one’s own shoreline.

Over time, the adjective’s meaning developed from the geographical idea of being on an island to the figurative sense of being detached from wider society and characterized by narrow-mindedness.
How insularity is actually used
