Iodized salt made Americans smarter

[Josquius]

You sure if they had gotten low scores it would have really lit a fire under their ass?  Getting bad grades sure didn't.

This calls for a study!
Lets IQ test a bunch of kids and tell some 150ers their real score and tell some others they scored 90. Then observe and enjoy.

Hm.... doesn't this also suggest that people who lived in coastal areas would have been smarter than people who lived inland, assuming they ate a lot of fish as part of their diet?

I'm not sure I'd agree with that.

In the army immediately prior to WWII, 75% of enlisted men had never finished high school, and 41% had never even attended. So, not the most educated group.
