It occurs to me that people with an impaired social awareness and capabilities are less likely to be aware of their impairment, much like the Anosognosic’s Dilemma. As the Wired survey is a self-diagnosis, I would not place too much confidence in its scores, at least as conventionally interpreted. High scores might suggest a high degree of self-awareness that there is a problem (which is good!)

True enough. But on the flip side it's pretty damn hard to not notice that you a completely different from most people around you after 20 or so years of experience. People with Aspergers' also have an impairment in the critical social skills of self deception, compartmentalization and creating and embracing a self image constructed for the purpose of public relations.
