CO2 increase of 400ppm decreases cognitive function by >20% [1] I frequently send this medium article [1] to friends + family for a basic dive into how CO2 affects our thinking and abilities at various levels in common areas. The article cites a study [2] which graphs cognitive score for different activities at different CO2 concentrations. Each activity's cognitive score is worse at higher CO2 concentrations, EXCEPT "focused activity" or "Information search" (up to some point) [1, note it is from 2016] https://medium.com/@joeljean/im-living-in-a-carbon-bubble-literally-b7c391e8ab6 https://medium.com/@joeljean/im-living-in-a-carbon-bubble-li...

That article really needs a pre-and post fixing his house. I find it hard to believe that stat you provide -- seems like a bit of a shiny lure without much merit. Maybe if CO2 PPM wasn't so high I could make sense of it.

I've started questioning this premise given that concentration of CO2 in the lungs (while resting) never falls below 10000ppm (I'm possibly underestimating this number). Though I'm not excluding the possibility that indoor CO2 concentration strongly correlates with cognitive underperformance, which may be caused by other compounds emitted by human body.
