> Something in our industrial processes must be screwing with people's serotonin levels because Psychedelics and other serotenergic drugs are becoming the defacto treatment method for a whole host of ailments. This is a comically bad inference. P1: We have ailments that can be treated with class X of drugs that act on body process Y P2: We increasingly use those drugs Conclusion: Z is messing with body process Y
Why is it "comically bad inference" to postulate that something environmental may be messing with our serotonin systems if psychedelic serotonergics cure ailments that we know require messaging via serotonin? (IBS ~ gut, migraine ~ brain, sleeping problems, and mood swings ~ brain)
How does it follow from a class of drugs addressing a class of ailments that there's some industrial process messing with some process in the body? Does that follow from every class of drugs that addresses any class of ailments?
If we find out that aspirin is even more versatile than we thought and helps with an increasing amount of ailments, how does it follow that there's some related industrial process behind those ailments? Why not just the more parsimonious inference that... aspirin is more useful than we thought?
