Uh oh - you're too smart!

A new study was released stating that the rise in autism might be linked to "clever parents" and that "couples who are both strong systemisers, for example, those who studied and works in STEM subjects (science, technology, engineerings and maths) and other fields related to systemising, are more likely to have a child with an autism spectrum diagnosis than couples where only one is a strong systemiser, or where neither is". 

Right.

So I'm skeptical about this of course. But, assuming there's a grain of truth in it, I'd like to see the autism prevalence numbers here in Huntsville.  We have the highest number of PhD's per capita, and the second highest number of engineers in the world last I checked. That's a lot of "strong systemisers" in one area, and I know that a large portion of couples here in this area are dual engineer marriages.  If current national autism rates are hovering around 1 in 100, then what is the rate here?  I wonder what we'd have to do to find out? I know MANY dual "STEM" couples who do not have kids on the spectrum. I'd have to find out how many of my friends who DO have autistic children have one or both parents in an engineering or related field. Your input would be awesome!
