It has been a minor article of faith that fandom has a higher-than-usual proportion of people with Asperger Syndrome. At least, it seems that some of the more negative traits associated with SF fandom also tend to exist in people with AS. As noted here, anecdotal, non-scientific surveying of the members of my friends list who have taken the survey suggests otherwise. But take large chunks of salt before forming any conclusions from either the on-line test or the survey of my f-list.
I seem to be hanging around the center of the chart, eh? Too weird for my co-workers and too "normal" for fandom?
