people who think the earth is flat aren't always retarded. some are. but some of them can perceive the 4th dimension and thus, to them, everything appears flat.  it's not some special power. they can't manipulate anything. but they can somehow perceive reality in a way that allows them to see the whole of reality as if they're viewing it from the 4th dimension - which is why there are some genuinely intelligent individuals who chose this hill to die on. it's because to them the earth (and everything else) is flat.
