I'm still not convinced that a typical straight male LW reader won't find, in his dating pool, quite a few women who don't behave like the prototypical chick in a PUA parable.
Well, the "buying a drink" story is an extreme example that's been canonized to make a point. But I'm convinced that in general, human beings are always unconsciously "testing" each other, and that this applies to everyone, male or female, autistic or NT. It's just part of how humans talk and joke around and communicate. For instance, saying hi to someone and smiling is "testing": you're seeing what kind of mood someone is in. Making a joke, or laughing at a joke, is "testing": you're seeing how other people react.
I don't see the "PUA" stuff as about sex or dating or men and women. It's about human social interaction in general.
I suggest there's a difference between "testing" and "checking". In a test, you're trying to find out whether the other person will fail or (in the case of bullies) hoping they will, while in a check, you'll hoping they'll succeed. I gather there are some people who are pretty evenly balanced on the chack/test scale-- if the other person passes, fine, it's a potential friendship, and if the other person fails, the harassment commences.
I think that a lot of small talk is what I call "pinging"-- "Hello, I'm here and friendly".
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:
