      Differences in intelligence between separate regions of the same countries are systematically linked to important life outcomes, such as income, health, fertility, and crime. https://www.sciencedirect.com/science/article/pii/S016028961730212X …pic.twitter.com/dNncB39TEP

      Intelligence correlate negatively with fertility?! Is there some sort of selection against intelligence?🤔

          I have read up a little about Dysgenics. It's so counter intuitive that my tiny brain has seized, dropping my IQ down to 95... I guess I should go and make babies now. 😣😰

          but but but! "dys" oddly makes you think it must be related somehow to negative outcomes.. Something we should be concerned about even? I've never heard of it before; only "eu"genics which everyone always goes on about so I know that's really bad outcomes right?
