But my question is, does PUA theorizing help him get an accurate model of what women in general are actually like? More generally, does it give him tools to get a better understanding of what reality is like? Or is it just giving him tools that help him to focus his attentions on a certain small subset of women?
I thought about it some more and honestly can't tell if you're right or not. On one hand, I never do cold approaches - there's always some eye contact and smiling beforehand - so the women I interact with are already very self-selected. On the other hand, I know from experience that a girl who rejected me in one setting (e.g. a party) may often turn out to be receptive in another setting (e.g. a walk), so it's not like I'm facing some immutable attribute of this girl. So every interaction with a woman has many variables beyond my control that could make it or break it, but my gut feeling is that most of those variables are environmental (current mood, presence of other people, etc.) rather than inborn.
Followup to: Do you have High-Functioning Asperger's Syndrome?
LW reader Madbadger uses the metaphor of a GPU and a CPU in a desktop system to think about people with Asperger's Syndrome: general intelligence is like a CPU, being universal but only mediocre at any particular task, whereas the "social coprocessor" brainware in a Neurotypical brain is like a GPU: highly specialized but great at what it does. Neurotypical people are like computers with measly Pentium IV processors, but expensive Radeon HD 4890 GPUs. A High-functioning AS person is an Intel Core i7 Extreme Edition - with on-board graphics!
This analogy also covers the spectrum view of social/empathic abilities, you can think about having a weaker social coprocessor than average if you have some of the tendencies of AS but not others. You can even think of your score on the AQ Test as being like the Tom's Hardware Rating of your Coprocessor. (Lower numbers are better!).
If you lack that powerful social coprocessor, what can you do? Well, you'll have to run your social interactions "in software", i.e. explicitly reason through the complex human social game that most people play without ever really understanding. There are several tricks that a High-functioning AS person can use in this situation:
