I’d be pretty cautious about putting much weight on those experiences of yourself or your friend that you’ve mentioned. Doctors see people everyday who swear that crystals cured their arthritis or that medication A works for them but not medication B (when B is just A with a different brand name). I’ve learnt to become very skeptical of the patterns I recognise in my own health. I’ve had experiences where I could have sworn that A was causing B that later turned out to be wrong.
As it is I don’t see why your prior would be “vegan diets make thinking worse” rather than “vegan diets don’t affect thinking” (my own suspicion) or even “vegan diets make thinking better” (I’m sure someone out there has their own anecdotes supporting this)
It wasn’t my prior at all. It was a response to observations that took many years to arrive at, it is also a response to some empirical evidence, which I mentioned.
