You should have asked him about iodine, some studies suggest that Iodine supplementation in pregnant women can raise iq by a whole standard deviation!,(reply>), @lowkey I guess it's both, also your parents are probably more intelligent than you think,(reply>), I was looking for a comment like this. I was hoping he'd ask also. I ended up extremely intelligent (135-140+ spatial), which I attribute to my mother's insistence that she ate fish every single day while she was pregnant with me. My parents on the other hand are only what I'd consider to be a bit above average. I could never make much sense of this aside from perhaps a genetic lottery, but when I learned about the influence of iodine on IQ, I made the correlation immediately.
