the.com/insularity

The art of mistaking your island for the whole map.

means A narrow, closed-off way of thinking that comes from being cut off from outside influences and treating your own small world as all there is.

from From Latin 'insula' meaning island, via the adjective 'insularis.' The literal sense — relating to an island — gave rise to the figurative one: people isolated on islands were seen, fairly or not, as having limited, parochial outlooks, cut off from wider currents of thought simply by geography. English picked up 'insular' in its literal geographic sense first, then let the metaphor of mental isolation grow from it.
