I find this topic fascinating not only because of its practical utility, but also because it presents a dissection of complex human social interactions in a way that's uniquely suitable for study and reaching genuine and reliable insight. Nothing even remotely like that, to my knowledge, has ever come out of any other attempt to study human social behavior.

Alas, the dissection analogy can be extended to people's reactions to it. Just like the prevailing religious opinion in ancient times was appalled at the idea of desecrating dead bodies even for the good of science, so the modern respectable opinion, even in venues like LW, is appalled at the idea that these aspects of human life -- which are in our society treated with an extreme level of both idealization and ideologization -- can be analyzed in such an undignified and desecrating but nevertheless correct way.
