"Anyone else got 3 or higher?"
I have a drug that could massively raise the IQ of the world's population, in total more than the power of all the world's computers combined. And it costs only a couple pennies per person per year.
Iodine.

For everyone reading this, it's already far far too late. I've been compiling some of the child & adult iodine studies into a little meta-analysis: http://www.gwern.net/Nootropics#iodine
