US Gained a Decade of Flynn-Effect IQ Points After Adding Iodine To Salt

cold fjord writes "I wish it was always this easy. Business Insider reports, 'Iodized salt is so ubiquitous that we barely notice it. Few people know why it even exists. Iodine deficiency remains the world's leading cause of preventable mental retardation. According to a new study (abstract), its introduction in America in 1924 had an effect so profound that it raised the country's IQ. A new NBER working paper from James Feyrer, Dimitra Politi, and David N. Weil finds that the population in iodine-deficient areas saw IQs rise by a full standard deviation, which is 15 points, after iodized salt was introduced.... The mental impacts were unknown, the program was started to fight goiter, so these effects were an extremely fortunate, unintended side effect.'"

    I wasn't asking it as I've been taking my iodized salt.

    No, I was busy jumping to conclusions with only a scant amount of knowledge in hand--which was gleaned from the headline and half of the summary.

    It's been offset by the introduction of fluoride in the water supply, which is simply Communist infiltration, Communist indoctrination, Communist subversion and an international Communist conspiracy to sap and impurify all of our precious bodily fluids. Hence, Dancing with the Stars.

    The evidence really is overwhelming. I dare you to read just the first article here. It is published in a very prestigious journal. Educate yourself please. We are trying to help you. The industries and corporations which have captured america's government do not love you. The toothpaste is a lie. Colgate will not make you sexy.

    You are doing it wrong. Most Americans buy the kind that has the flavored coatings. You can find it on nearly every aisle of what is commonly called a grocery store. Just be sure to stay out of the area labeled produce.
