No expertise on the formation of a survey (wasn't thinking of a survey, at all, actually, just kind of randomly asking the question at the bar, or some such, just for the fun of it).

I was just coming at this from a Word-Geek perspective: that the word geek (originally Gek) comes from the Old Dutch language and originally meant "Village Idiot" ...in that those folks were often non-verbal, and "gek" was "imitative" of their speech, supposedly (Gek shows up in English sometime in the 1500s, iirc). And then, come full circle, and in modern times come to popular-science discovery that those whom we call "Geeks" tend to fall on the autism spectrum... and those are the same people who'd have been labeled as village idiot, back in the day...

And, based on one of the soliloquies Shakespeare wrote for Hamlet to say, he certainly recognized the personality type, since early on (before "To be or not to be") Hamlet bemoans his tendency to over think things, rather than act, and how that tends to lead to getting beat up on and teased, and called a coward. And Shakespeare, I'm pretty sure, had never even heard of World of Warcraft or "ThinkGeek."
