I’m not sure that statement is really meaningful in a nontrivial way. If we just consider autism, then there’s some opposite end of that spectrum; of course everyone’s somewhere on it, but you would expect most people to be at 0, or as near as makes no difference.
This seems a good time to point out that actually, there’s now pretty good evidence that that spectrum does not end at neurotypicality, but continues past it to an actual “opposite” of autism—schizophrenia. Assuming this is correct, everyone is indeed somewhere on that spectrum!
