I lack information? Your arrogance is astounding.

I guess since you read fluoridealert.org that makes you an expert and an academic scholar, right?

It hasn't been "proven" because the idea of IQ is controversial to begin with. Epidemiological studies intending to measure the IQs of populations are extremely difficult to do with any precision, let alone adding in the factor of fluoride exposure during development(another difficult factor to know with much certainty) and trying to link them. Some of the studies are interesting, but far from conclusive.

This is the exact mindset that pisses off doctors and scientists. "Get educated about your field, man. I sit at home and read the internet and I know the facts."
