I don’t know. I think it is fair to say that Autism existed prior to Tylenol, so the root cause of autism isn’t Tylenol. Sure it could be a contributing factor (it isn’t according to the cited study).
Schizophrenia, autism, etc. are complex genetic disorders with a spectrum of symptoms. They likely need multiple hits from genetic and environmental risk factors to develop the disorders. Autism diagnoses are increasing which means either we are better at identifying the disorder or environmental factors such as poor diet and pollution contribute. Likely both, but the former is probably a better explanation.
The statements of the meme are in mathematical form
A≠B B≠C
Therfore A≠C
which is not necessarily true and what @meowmeowbeanz is referring too.
