Practical Ethics: The perfect cognition enhancer - it is iodine. Iodine deficiency affects up to 2 billion people, impairing at least 18 million children mentally each year and most likely costing mankind several billion IQ points. Iodized salt is cheap, safe and even OK to fairly strong libertarian anti-forced medication views.
The scary part was that I, a researcher in cognition enhancement, had not thought about it before. I have been looking at lead and other heavy metals, even folate and other nutrients, but I had completely overlooked this key micronutrient. A good reminder to read the literature more carefully, and a demonstration that sometimes massive improvements can be achieved surprisingly simply.
