The quality or state of being egocentric; excessive self-centeredness or the inability to see things from another person's perspective.
From egocentric (ego + centric) plus the noun-forming suffix -ity, creating an abstract noun for the quality itself. Latin ego ('I') combined with centrum ('center').
Egocentricity isn't always bad—babies need it to survive, and artists often need it to follow their vision when the world says 'no'—it's the human equivalent of a necessary operating system that some people never update.
