-Rather, your medianworld is a real human Society that would spit out something very much like you at the center, rather than at the margins: for everything that makes you weird _here_, half the population of your medianworld is even more so. The worldbuilding problem is: how would that _actually_ happen, given different initial conditions, but the same underlying laws of economics, sociology, psychology, _&c._? How would the macro-level features of Society shake out, were Society to supervene on that population?
