I have often seen that people who support more consequentialist inferences display lower social skills and abilities.

The "theory theory of mind" says that autistics lack the ability to simulate someone else's reasoning. If this is true, and Asperger's is like autism, people with it might be likely to judge people on the basis of consequences, since they have no model of other peoples' intentions.

Although, now that I think about it, if someone has no cognitive model, but just observes a large set of instances of

<situation, action, outcome>

and finds a way to classify them as "good(action)" or "bad(action)"; and if situation + action usually determines outcome; is there any difference between being a consequentialist (making a lookup table of outcome -> action), or a deontologist (making a lookup table of situation -> action)?

I still don't understand the connection between Asperger's and compartmentalizing.

if you are an altruistic consequentialist, and you search heard for the most important charitable cause, you'll find that Singularitarianism is it.

How does that argument rely on you being a consequentialist? Other ethical systems have to do with, eg., measuring intended consequences instead of actual consequences, not ignoring consequences.
