WHEN IT RAINS, IT POURS:

Study: Iodine Salt Use May Have Increased The American IQ  (CBS ATLANTA, 7/23/13)

Although iodine deficiency remains one of the world's top causes of preventable mental retardation, many Americans don't realize that its use has increased their IQ's.

According to a new study from James Feyrer, Dimitra Politi and David N. Weil, Americans' IQ has increased one full standard deviation - 15 points - since its introduction to the country in 1924.

The study found that for the one quarter of the population most deficient in iodine this intervention raised IQ by approximately one standard deviation during the time of its use. The study finds that the drug increased IQ's nearly 3 points every decade since its introduction, and likely within just ten years of use.
