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!
I’m not a scientist, so I’m looking at the subjects here from a different angle. I’ve read the Harpending/Cochran book and I’ve read the book “Born on a Blue Day” by Daniel Tammet, on his Asperger’s Syndrome. I wrote an article offering the notion that perhaps we are all somewhere on the autism disorder spectrum: http://pavellas.wordpress.com/2008/05/21/where-are-you-on-the-autism-disorder-spectrum/ Best wishes, Ron Pavellas http://pavellas.com.
