It is not that autism is more pronounced on here. Not specifically. There is some correlation between autism and geeks, probably. I mean all kinds of neurological issues aren't uniformly distributed throughout the populace, just look at the genetic problems Jews and only Jews seem to get. But what we're seeing is that people who actively use (or even lurk) internet forums in general are not part of the general population anyway. If this test produced a different result from the set of Facebook users, I should be more surprised. But I am not surprised at all that an internet forum has different results because it is obvious that less than 10% of the population accounts for 90% of what is written online. Half the population uses the Internet exclusively for porn and videos on YouTube. This is why it seems elsewhere on the internet everybody online loves cats and Ron Paul. It's like expecting an IQ survey of Usenet users in the old days to follow a normal distribution, when it is was clearly the inverse! Even ignoring the rest of the net, even on SR the majority of people don't seem to use the forums. Technocracy! Soon we shall evolve into Morlocks and farm Facebook users... oh wait.
