We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
We know many scientific studies are false. But we usually find this out one-at-a-time. This – again, assuming the new study is true, which it might not be – is a massacre. It offers an unusually good chance for reflection.
And looking over the brutal aftermath, I’m struck by how prosocial a lot of the felled studies are. Neurogenesis shows you should exercise more! Neurogenesis shows antidepressants work! Neurogenesis shows we need more enriched environments! Neurogenesis proves growth mindset! I’m in favor of exercise and antidepressants and enriched environments, but this emphasizes how if we want to believe something, it will accrete a protective layer of positive studies whether it’s true or not.
I’m also struck by how many of the offending studies begin by repeating how dogmatic past neuroscientists were for not recognizing the existence of adult neurogenesis sooner...
