Isn't that what science is? Our understanding changes all the time based on new experiments. "Settled science" isn't a thing imho.

Science is the art of prediction. When I say settled science I mean that the predictability has overcome all possible experiments so far. For example, how planets move around a star is settled science.

Huberman sometimes passes the results of a single experiment as if there are no more hurdles to overcome.

Huberman wildly oversells and overgeneralizes. Apparently that's what listeners want.

And uses a lot of words in doing so. “Effect” and “size” together are usually absent.

I think he’s just a curious guy who loves to experiment on himself, and talk (a lot) about it. The problem comes when people listen to his podcast looking for magic bullets and take everything as strictly true or false.
