From somone named <Anonymous> on G+ i saw a link to a blogpost from a doctor about the dangers of fouride. that sounded interesting but potentially nutty (conspiracy nuts like such ideas). from reading the discussion at varius sites it was still unclear what i shud believe. so i downloaded the actual study cited and read it. its a pretty decent correlational systematic review. causation can be difficult to establish here, but ther shud be som natural experiments that can be used. for instance, som areas currently have high levels of flouride in the water for natural reasons. we can test the children of those areas, and then fix the drinking water by lessening flouride levels to those used in western countries, so about 1mg/L. then wait som years, like 10, and test som other children. if flouride is causing lowered IQ scores, they shud hav gone up by now. apply som stats to get rid of any potential Flynn effect. shud be somwhat easy to make this experiment in developing countries.
