Well, I could easily dismiss that on the grounds that those people might have the wrong mbti type, or that they have incorrectly self-diagnosed themselves as so many people have on the internet (or indeed, historical figures!).

Asperger's is all the rage for the socially maladjusted nowadays.
The reason I say that Introverted Sensation is a better fit is because another common sympton of Asperger's (and Autism in general) is an ability to filter large amounts of data for very specific information (which they then collect, for example car licence plates starting with a 7), which is a textbook definition of using Introverted Sensation.
