Reply to comment by adamant2009 in TIL A 2017 study found that the introduction of iodized salt in 1924 raised the IQ for the one-quarter of the population most deficient in iodine. by kstinfo

Measurable intelligence has been steadily rising since the 50s, and arguably longer. It's hard to say how much of that is from salt.

Aren't we getting weaker too? Something like the grip strength of humans who were hunter gatherers far exceeded modern day?

If so it's like we're redoing our fallout built and moving stats from strangth into intelligence

Our brains are smaller too tho. Our jaws are also getting smaller and weaker. Kinda like wolf to dog transition. We are kinda domesticating ourselves and I doubt we are actually smarter now.

The brain being smaller doesn't neccesarily mean we are getting stupider, the correlation between brain size and intelligence is weak.
