This was studied because it sounds reasonable on paper and several small studies showed a small link.

However, they did a very large cohort study with hundreds of thousands of subjects. The link completely disappears when genetics are accounted for via sibling pairs.[0]

It took almost two whole minutes of Googling for me to disprove this nonsense. Which shows that RFK did less than 2 minutes worth of research before panicking the world.

I will say that this study presented a major challenge to the tylenol hypothesis. To my mind, there is still a remote possibility that the tylenol hypotehsis might just be relevant to a smaller subset of autistic individuals...but I am coming from the general outlook of believing autism needs to be subtyped when looking at etiology.

Personally, I very much agree. I feel that while the idea of a spectrum wasn't a mistake, it was only a start.

I did, but I'm on the spectrum so I failed the vibe check. ;)

Didn’t whole internet get angry for Trump’s administration publishing a warning that Tylenol during pregnancy may cause autosim?

Can you explain the logical leap you're making here? Unless this is RFK Jr we're talking to, you're comparing two wildly different contexts.
