i have read somewhere (no, i dont really remember where), that we actually have *bigger* brains (not to be confused with intelligence).
the article stated that autistic brains have a lot more connections then an NTs, but that actually was the problem.
imagine a city with a wheel street layout, concentric circles with direct lines trough them; like paris around the arc de triomphe.
that street plan actually works well, if you regulate it, and is the NT method. though; it might take a while to get 2 blocks further, becouse you got to go to the centre first.
now the autistic brain has many, many roads. "i gotta go there" "lets build a road".
this makes it easy to go from one place to another, but the chaotic floor plan it results in makes efficient travel nearly inpossible.
