  > The CO2 cognition studies are almost definitely wrong. The military has done numerous studies over the decades with much much higher CO2 levels with none of the reported cognitive results reported more recently.

So dozens of studies by disinterested parties are wrong, yet the studies by a single interested party is right? If you really have good standing for believing this, I would like some more information. I am considering installing such a system.

Thank you.

1. It’s not a single interested party. What I called military studies were by at least 3 completely separate groups. The Navy, the Air Force, and NASA. There have also been studies by the EPA, and “disinterested” academic groups.

2. There aren’t dozens of positive studies. There are a handful by 1 or 2 research groups.

There was a meta analysis in 2020 looking at only the academic literature (so excluding military studies). It found that for every positive result there was at least 1 negative one.

Here’s a good walkthrough of that paper.
