attention: smoking gun !!!!!!!!!!! > the determination about lower iqs in children was based primarily on epidemiology studies in non-u.s. countries such as canada, china, india, iran, pakistan, and mexico where some pregnant women, infants, and children received total fluoride exposure amounts higher than 1.5 mg fluoride/l of drinking water.  wow surely it couldnt be any other factor here right /pol/? surely the iq differences found is the fluoride, nothing else could be different about these countries and europe/america  hahahaha this is genuinely hilarious
