I've located an interesting article on this topic, I was sure that INTJs were along the bell shaped curve towards these "traits", and this pretty much confirms my observations. My comments in blue, article passages in black. Link to article at the end of this post.

This article challenges the received view through a subtle but important shift of emphasis. Rather than conceiving of autism as a deficiency, it instead considers if autism might be better characterised as a different cognitive style.
As we'll see its an orientation to the inner world of the self and towards systems, processes and patterns... depersonalisation is just a manifestation and not necessarily the "cause".
Autism is diagnosed on the basis of abnormalities in the areas of social development, communicative development, and imagination, together with marked repetitive or obsessional behaviour or unusual, narrow interests . Individuals with autism may have an IQ at any level. By convention, if an individual with autism has an IQ in the normal range (or above), they are said to have 'high-functioning autism' (HFA). If an individual meets all of the criteria for HFA except communicative abnormality/history of language delay, they are said to have Asperger's syndrome (AS). In this paper, we focus on AS and HFA since we accept that an individual who is lower-functioning necessarily has a disability in the form of retardation.
Note that High functioning autism basically states that the person can be well above average in the IQ stakes. Wouldn't it be fair to say that "High IQ coupled with unique observations, obsessive behaviour and pattern/systems orientation are ideal traits to success in many technical fields?"
The arguments for viewing AS/HFA as a difference rather than a disability- The child spends more time involved with objects and physical systems than with people (Swettenham et al., 1998); (This has the Thinking and judging traits all over it - INTJs)
- The child communicates less than other children do; (Greater Introversion, Thinking more and less connectivity with non thinking kids - INTJs).
- The child tends to follow their own desires and beliefs rather than paying attention to, or being easily influenced by, others’ desires and beliefs (Baron- Cohen, Leslie & Frith, 1985); (INTJs sticking to their orientation and not being constrained by group behaviour)
- The child shows relatively little interest in what the social group is doing, or being a part of it (Bowler, 1992; Lord, 1984); (INTJs)
- The child has strong, persistent[2] interests; (INTJs select their interests and tend to follow them vertically into immense detail)
- The child is very accurate at perceiving the details of information (Plaisted, O'Riordan & Baron-Cohen, 1998a; Plaisted, O'Riordan & Baron-Cohen, 1998b) (Thats a function of intuitive projective thinking which means that causal patterns infer the requirements and detail).
- The child notices and recalls things other people may not (Frith, 1989); (INTJs are always scanning for exceptions (not pattern conforming) and looking for detail around the edges that is the key to the answer. Also, when they are interested they are really interested, bit of the obsessive trait coming through).
- The child’s view of what is relevant and important in a situation may not coincide with others (Frith, 1989); (INTJs starting building their logic framework at a very early age, a piece of information can be very important to an INTJ child if it conflicts with his/her logic or if it somehow or someway is far more important than its acknowledgement.
- (dates, . The child may be fascinated by patterned material, be it visual (shapes), numeric timetables), alphanumeric (number plates), or lists (of cars, songs, etc.); Obviously this is the INTJ pattern forming traits. I do somehow believe that its almost that patterns offer non personalised mind communication, like a riddle that needs to be solved and brought to order (Like with the Judging function). INTJs command the physical world, structure order, predictability and efficient action. Understanding patterns is like to leverage the logic, if you understand the pattern you Intuitively know the outcome. The more patterns solved the greater the intuitiveness.
- The child may be fascinated by systems, be they simple (light switches, water taps), a little more complex (weather fronts), or abstract (mathematics); INTJs are fascinated by the achievement of outcomes from systems, they appreciate the intellect of the maker of the machine. By understanding the machine they understand the logic of how and most importantly why.
- The child may have a strong drive to collect categories of objects (e.g., bottletops, train maps), or categories of information (types of lizard, types of rock, types of fabric, etc.); and (Because INTJs tend to dive vertically into the depths of detail, where the topic has limited detail then they are likely branch towards closely connected items. Categories of an item are more logically connected).
- The child has a strong preference for experiences that are controllable rather than unpredictable. (Systems are controllable, they are the master. Unpredictable situations reduce power to control or influence).
The list could be expanded but these 12 behavioural features are sufficient to illustrate that children with AS/HFA are different in ways that can be described in value-free terms: none imply any necessary disability. Rather, most of the above facts show the child as immersed in the world of things rather than people. This might be a basic way of defining the difference between a person with an autism spectrum condition and one without it .
There's lots more to say on this article - as time permits. The orginal article in full length can be found here -> http://www.geocities.com/CapitolHill/7138/lobby/disability.htm One thing to note is the hightend propensity of high performing intellectuals to have this condition and the increasing incidence (Which I believe is more related to the ability of "birds of a feather to flocking together" and having children which was less the case with lower social mobility and less meritocracy in the past).
