Tucker Max & Geoffrey Miller

The relationship between fitness and survival creates a deep asymmetry in nature.

It’s why, for women, it’s even more important to be sexually disgusted by ineffectiveness than to be sexually attracted to effectiveness. Effectiveness requires a lot—thousands of genes, hundreds of adaptations, dozens of organs, and millions of neurons working together in awesomely intricate ways to produce sustained, adaptive behavior. But there are an infinite number of ways to be ineffective as a male animal, from being spontaneously aborted as a blastocyst to losing competitions to rivals, and literally every point in between. […]

Thus, apart from cultivating signs of effectiveness, it can be even more important to stop showing signs of ineffectiveness. In most species, in fact, a lot of female choice is about avoiding the bad rather than approaching the good.

The idea that a developing fetus is part of the woman’s body is so biologically ignorant that I would call it medieval, except that would be to insult the medievals! The fetus is not like an appendix or a gall bladder. From the moment of its conception and implantation in the wall of the mother’s uterus, the fetus is never a part of her body, but is a biologically distinct and complete living being which is, in effect, “hooked up” to the mother as a life-support system. To say a fetus is part of a woman’s body is like saying that a person on life support is part of the iron lung or the intravenous equipment. Having an abortion is not like having an appendectomy. It is killing a separate human being, and to try to justify that on the grounds that a woman can do what she wants with her own body is just politically correct ignorance.

Why would the amount you worry about disease be a significant predictor of the a mount you worry about social relationships? After all, you might have had a history of dependable and reliable relationships, but some unsettling brushes with disease. The answer must be that the menta mechanisms that underlie worrying about disease share brain circuitry with the mental mechanisms that underlie worrying about other things. Any variation in the responsiveness of those shared circuits will show up in all kinds of worrying, not just one kind. It’s a bit like a car. The handbrake and the footbrake do different jobs and have some separate components, but they also rely on the same hydraulic system. As a consequence, a loss of brake-fluid pressure will show up in reduced effectiveness in both brakes. The more two components draw on shared machinery, the greater the extent to which the performance of one will be a predictor of the performance of the other.
