I remember an old study linking ultrasounds to lefthandedness. It was legit. Families with access to ultrasounds lived in countries/areas where lefthandedness was more culturally accepted, places where it was not drilled out of kids. The study was correct, but anyone touting it as causation was totally incorrect.
Fyi, sharks are way more likely to attack people with australian accents. Never go swimming with an auzzi.
Going back to the top of this thread, I agree that correlation does not mean causation, but in this case, we do not yet even have a justifiable claim of correlation, and RFK Jr. has repeatedly demonstrated his propensity for substituting unfounded opinion and incorrect data for empirical facts, if it suits his agenda.
I wonder whether the political actors in question don't understand correlation != causation, or whether they hope that enough of the populace does not understand it in order to further some goal. But what goal? Buying cheap drug shares? Seems ... silly.
