Ha. That for me actually seems to be impaired, which is why I had to do special education. These days I usually have enough of a knowledge base to build hypotheses for most situations, but it was far more difficult for me to reason about the cause of things that I had nothing else to relate to. Stuff like this is probably why autism tends to be treated like some sort of super learning impediment.
Anyway, I think about causes first when I am either performing actions or processing other performances of actions. It's one of the reasons why I can appear to be good at empathy to certain people, because I can usually nail down the exact reason for something far better than others can guess why it maybe could have happened. It's weird how that works sometimes.
