The real kicker for me is how absurdly high the effect is in the recent studies. You should basically see A students failing tests when the teacher closes the window.

You should see huge swings in standardized test scores based on building ventilation.

Companies with good ventilation, should absolutely dominate their markets.

And nuclear submariners operating at 10,000 ppm should basically be non functioning if there is any kind of dose dependent effect (which the studies in question say there is).
