Actually the poll results are kinda interesting.
Vast majority of humans have black/dark brown hair.
Only like 1 or 2 percent are redheads. But thats the whole planet (including Africa and Asia).
WP users tend to be from the English speaking world: Americans, Brits, Canadians. Presumably mostly White.
Redheads make up five percent of northwest european populations. The Celtic Fringe of the British Isles is the highest ( Scotland 12 percent, Ireland 10 percent, with high numbers in Wales as well).
So if WP were representive of caucasians in general you expect like 6 percent redheads.
But the poll has 21 percent redheads (higher than Scotland).
So maybe that IS a significant clue to correlation between hair color and autism.
Was born blond and gradually morphed to an almost black dark brown color in my teens. Stayed that way until I turned gray. But do have one redheaded male cousin.
I find that most polls that inquire on hair colour tend to be skewed toward Caucasians. Among ethnicities that are generally considered to be exclusively black/brown of hair colour, like East Asians, South Asians, sub-Saharan African etc, one can find a range of different hair colours from pitch-black to auburn, and from blueish tones to a more reddish hue.
