Your quote doesn't actually say that causation requires correlation, though it does make sense.
What do you think "correlations must first be confirmed as real" means? It means that the correlation must actually exist. It can't be just a one time coincidence. I presented multiple times that DDT did not exist or was not in use at the time polio was clearly affecting people.
Polio symptoms are described as far back as ancient Egypt.
The first medical description was in the late 1800s. 1789 by the British physician Michael Underwood. https://en.wikipedia.org/wiki/Michae...od_(physician)
Jakob Heine did a study of polio in 1840, almost 40 years before DDT was first made. https://en.wikipedia.org/wiki/Jakob_Heine
In 1916, NY had a polio epidemic, 23 years before DDT was ever used as an insecticide. https://en.wikipedia.org/wiki/1916_N...polio_epidemic
DDT was first synthesized in 1874. It's use as an insecticide wasn't discovered until 1939. https://en.wikipedia.org/wiki/DDT
In 1928, the iron lung was introduced to be used for polio patients and keep them alive. No DDT was being used as an insecticide.
Africa stopped using DDT in the 1960s. Polio was around when DDT wasn't being used. By the time DDT was reintroduced to help control malaria, the cases of Polio had dropped to almost zero due to vaccines.
It's funny how you seem to completely ignore the evidence and go off on another pseudo-science tangent. If polio existed for thousands of years before DDT and polio existed where DDT wasn't being used and DDT was being used where polio wasn't prevalent then the 1950s are nothing more than a coincidence that in no way shows a correlation. It certainly isn't statistically significant enough to show there is a correlation.
What am I not accounting for? What dosage of DDT existed in 1916 in NY? What duration of DDT exposure existed in 1916 in NY? You keep claiming that DDT causes polio and then backtrack and claim it could be anything. Since you have no evidence of anything causing polio but there is evidence of the polio virus causing polio how can you state with any certainty that a virus doesn't cause polio? All you have isYou're not accounting for various things- things like dosage, duration of exposure, health of those exposed and perhaps most importantly, someone to test in a competent fashion for polio like symptoms. Also, as I've said before, I have never claimed there was any evidence that DDT was the -only- cause of polio. This should be obvious anyway, as polio was around before DDT. -Other- toxins were around though.
as you deny something and offer no valid explanation that stands up to scrutiny.pseudo-science
