And wow, open-plan is bad.
Why hasn’t Woodley done a study on this?
It could be one factor behind modern declines discussed in At Our Wits’ End.
TLDW: CO2 levels caused by breathing (in enclosed spaces) and urban environments cause huge drops in cognitive performance. It can cause health problems down the road. Maybe working in an open-plan office with no open windows (too high up) will one day be viewed with the same disdain as coal mines.
