Agreed, and I'd put it at at least 50-50 that it's outright wrong.

(My understanding is that they've had lots of trouble doing studies on this, partly because it's hard to get lower-functioning autistics to focus on the things that the testers want them to pay attention to, so many of the older tests gave results that were, on further examination, incorrect. The most recent results I've heard about say that autistic people are at least as empathetic as neurotypicals, on average; the social problems have more to do with difficulty using information gained via empathy than with the empathy not being there at all. I actually wouldn't be at all surprised if it was an integration issue similar to the sensory integration issues that are so common.)
