>It's just the idea that you read that titillates them. They usually don't give a fuck about it otherwise.
This is true. I've used academic stuff, literary/philosophical knowledge, and verbal intelligence as my main schtick to get laid for like a decade. I cannot tell you how many "sapiosexuals" I have basically just talked at until they put out. But they never reciprocate, at all. I am talking fucking actual PhD-holders in Psychology or Literature, and I know more about their field as a dilettante in a totally unrelated field.
So you just talk at them, and give them the occasional opportunity to chime in. Basically, set all the terms of the conversation, but give them little dangling opportunities for input, or ask for their input on shit that doesn't matter. You don't want to be completely one-sidedly obliterating them, so you don't want to ask what they actually think of some topic (even one within their field), because then they feel bad that they're a dumbshit. What you want to do is show off how much YOU know about that topic, and then carefully circumscribe their possible input so that any fucking retarded banal opinion or platitude they have is a valid contribution.
Alternatively, pick a subject you don't really know a lot about, but still way more than them because you actually have integrity. Then openly admit you're a dilettante, relatively often, and affect a kind of gay-ass wide-eyed wonder about the topic. Because you're repeatedly saying you know nothing, they can be like HAHA ME TOO LOL :P I REALLY GOT A LEARN MORE ABOUT IT XD! even though they know actual nothing.
The upshot is that the girl won't feel condescended to or bullied, or that you're showing off, which is effeminate. You want your dominance to be effortless. Women crave the feeling of being a subordinate, NOT the feeling of being completely destroyed by a superior. Especially the smart ones, or ones who think they're smart or will some day be smart pantsuits ladies. So, most rich girls in university, and most educated professionals.
The more superficially intelligent the girl, the bigger their inferiority complex. They know they are in a man's world and they are frankly in awe of intelligent men. Like, they actually have no idea how intelligence, passion, or depth work. At all. If you arrive on the scene and show that you are one of those people, it will trigger their memory-complex of all the weird passionate men and professors they met in college, whose knowledge and talent left them literally uncomprehending and in literal awe. Women don't see individual men, they see aggregate performances. If you mantle the appropriate performance, you're fucking in. They just assume you're God.
Ever see that episode Space Seed of the original Star Trek, where McGivers falls completely in love with Khan because he's walking charisma, and because she's an historian who associates ALL "charismatic gods" with Napoleon, Caesar, Hitler, etc.?
