Two interesting things about that thread - 1. he's gathering real data on women not just theorising, which is smart, 2. something you can't control - looks (fundamentally, obviously if you're very overweight [like me] you can fix that, same with the way you dress etc.) - has the biggest impact of all.
Moral of the story - real data trumps everything, even if that data makes you realise you aren't entirely in control of the situation :)
or just go learn how to pick up girls. the skills are relevant to entrepreneurs.
In fact, the PUA guys have taken a lot of ideas from the exact same sources that are used by sales-people, marketers, etc. For example, Robert Cialdini's book Influence: The Psychology of Persuasion is a popular read amongst PUAs. You'll also see those guys recommending various books on sales and presentation skills, recommending improv classes (something else sales guys sometimes do), etc.
So yeah, there's definitely a sort of connection there... :-)
