That's not the case, though. Yes, they work the numbers game, but that will apply to you regardless of how you behave; many women will shoot you down, only some will respond positively.
They simply teach you how to behave to attract women. It has nothing to do with 'seeing through' anything. You don't 'see through' a woman in lingerie. You're attracted to her because she looks attractive. Behavioral techniques can make you attractive as well, that's all.
Anyways, I don't like to evangelize because I don't like to help my competition, so do what you want.
