But i have absolutely no idea whether to trust RationalWiki or not. I tend to assume anything with "rational" in the name is anything but (unless it's about fractions).
Generally, the wiki tries to promote science and oppose pseudoscience, and often does a good job. The problem is with politically charged topics, where politically correct ideas are automatically presented as science, and politically incorrect ideas as pseudoscience.
Unlike Wikipedia, the idea of impartiality is considered a joke at RationalWiki. As soon as you decide that an idea is pseudoscientific, you are allowed and actually encouraged to use the "snarky point of view", which provides an excuse for exaggerations or straw men, because if anyone objects, hey, I was just joking, don't you understand a joke? Of course the articles do not distinguish the factual and the snarky parts, so everyone is free to make their own guess.
As for elites -> more children, since there were various routes into "elite" for smart/competent/etc. people (the church in various roles, not all of which precluded reproduction; skilled trades/guilds, etc.), it did have a positive effect in amplifying traits (intelligence, etc.) which I think people broadly support (I do). Similar to the assortative mating issues with colleges and elite workplaces today.
