I've sometimes wondered just that. My parents had rather a restricted social life and seemed to want me to stay away from people.....they knew nothing about conflict resolution and failed to demonstrate the look and feel of a happy family. I had no shortage of explanations for my poor social progress, and I fought tooth and claw against acting the part of a lonely introvert.
Years later I discovered AS and was diagnosed. Ever since, there's been this "hard-wired" feeling about the whole social thing.........it had been bad enough to have Hans Eyesenck bleating about basic personality being fixed (I'd scored on his tests as an introvert with self-esteem problems), but if it was going to be a brain wiring thing, I stood even less chance of fixing it.
So yes, it would be nice to think I was just badly trained. But it would seem odd that AS had skipped a generation and that the traits fit so well. I can see how my parents screwed up on my social grooming, but not how they could have taught me to have special interests, to be slow in jumping from the detail to the overview, to be poor at multi-tasking. Nobody obsessionally collected anything much in my family.
I also have a few experiences of achieving the kind of things that only a confident extravert could expect to do, but the learning didn't stick. I found I couldn't repeat my performance. I suspect that's the "rubbery" nature of AS, i.e. you can use a lot of energy and force yourself to perform very well for a while, but as soon as you stop the abnormal effort, everything goes back just the way it was.
Whatever the case, if the right skills weren't provided in childhood, you're going to do a lot better if you get studying and put that right, whether you're AS or not. A lot of our mistakes are made just because we don't know what to do in this or that situation.
