The Mad Economist's Children

Bryan Caplan via Marginal Revolution:

...normal people can expect to be like their kids. But that's not saying much, because normal people can expect to be like any random person they meet! The story's very different for weirdos. By definition, weirdos never have much in common with random strangers. With a zero parent-child correlation, weirdos will feel equally alienated from their children. As the parent-child correlation rises, however, weirdos' incompatibility with strangers stays the same, but their expected compatibility with their children gets stronger and stronger.

Now let's look at these facts like a mad economist. There are two ways to surround yourself with people like you. One is to meet them; the other is to make them. If you're average, meeting people like yourself is easy; people like you are everywhere. If you're weird, though, meeting people like yourself is hard; people like you are few and far between. But fortunately, as the parent-child correlation rises, weirdos' odds of making people like themselves get better and better.

Caplan concludes the analysis by pointing out that as weirdness rises so does incentive to have children. He could have also said that, entailed in that, weirdos have more incentive to find and keep a long-term mate. Does this help explain non-standard mating patterns in weird people?
