@ShaulaEvans Note that this was only a one month study. It doesn't capture the impact of a reduction in long covid.
@ShaulaEvans conclusion: increasing pollution around the globe really is making us all stupider.

119 participants / 30 days.
I'm not a scientist but this seems far from a large enough sample to form any conclusion. One wonders where the financing for the study came from.

@ShaulaEvans good ventilation installed in schools also improves grades notably.
