Why not test this? Probably only suggesting this because I’m reluctant to trust one or two papers on this alone. Would be cheap to do. eg:
-Write two similar tests of the key dimensions of performance you care about.
-Recruit a number of participants
-Put each test in an envelope marked 1 or 2 for first or second, then put two envelopes in a bigger envelope, making sure that the smaller envelopes marked 1 and 2 don’t contain the same test.
-Assign people to two rooms. In one, a friend has raised CO2 to 1200ppm, in another, its 600ppm. You don’t know which and you don’t tell them which. They do test one first in one of the rooms, and test two second in the other.
-Look at results
