Just curious, were you inspired by my post yesterday?

But anyway, I like your enthusiasm but there's quite a lot of flaws in your story

First off, our brains went through many evolutionary pressures and experiences. The brain is literally a bunch of stuff built on top of each-other, which is often contradictory and serves different interests. It's all held together by the neocortex, which is a robust all-purpose pattern recognition information system. What you're saying isn't wrong per se but it would do you well to qualify that it's part of the bigger picture.

To give one example of how different evolutionary pressures create different aspects of the female brain is the War Brides phenomenon. Close-knit societies will favor women who create strong bonds and so on, but all throughout our history, tribes have been conquered, the men killed and the women taken by the winners. This favors women who could switch allegiances quickly (and rationalize/hamster it).

Second, this is just wrong:

Because this is her best chance to garner resources for herself and her offspring.

This is in no way a woman's primary motivation for seeking who to mate with. Women prefer to have Sexy Sons over all else. The brain is our peacock's feathers. The singing and dancing mating ritual birds and other animals do is already a primitive manifestation of probing for the proper inside of the other's skull.

Genetically, the worst you can do is mate with someone who has suffered from a lot of genetic degradation. This is imperceptible, which is why we use heuristics to peer into the other's genetic purity. The brain is ideal for this due to its complexity.

Above all material things, women want to see you have a fully functioning brain! That is sexy. That you can figure stuff out and do things right. Social proof and preselection are heuristics they (we) employ to find out who the brain-masters are. Material gains are secondary. Physical attributes are secondary.
