So does this mean we can now expect populist politicians to crank up PM2.5 emitters at a massive scale prior to elections?
Out in the countryside where my parents live in Texas, people are even proud that they burn their trash as if they're sticking it to some sort of treehugger group rather than to the inner lining of their (and all their neighbors' and loved ones') lungs.

IQ has a bad rap (rightfully so, thus no disagreement there). In the cited works they use tests that in the past were called IQ tests - though here all are called cognitive-scores. Why wouldn't IQ tests be great for studying short term cognitive effects? I would trust their values for these type of studies the most: how does lack of sleep, being drunk, after exercise, etc affect your ability to solve abstract problem…
> Why wouldn't IQ tests be great for studying short term cognitive effects? IQ testing is designed to test for intelligent behaviour, which is largely based on long-term neurological development. The connections in the brain, densities of neurons, and long-term potentiations don't change greatly on a short-term basis. Measures which fluctuate based on spot-performance factors are typically deemed unreliable for the p…
In addition, to me, it sounds that you are arguing that a test on which you do worse when tired, sleepy, hungry etc. is not an appropriate test because it fluctuates depending on your state of mind. I don't get that.
David Heinemeier Hansson (DHH of Rails fame) gave a great talk on this recently, though he focused more on indoor air quality and its cognitive impact: https://www.youtube.com/watch?v=MRqh8oLY7Ik
How do you all monitor air quality? I personally have a couple of devices (an Awair and a Flow). They seem to under-report PM2.5 compared to purpleair, airnow, and waqi.
I've been tempted to get the purple sensors because at least the purple map seems reliable (so maybe their stuff is better?).
Plug: if you care about this topic and are interested in working on this problem, we're hiring at Aclima. We've got contracts with the major air quality regulators in California, and are looking to scale. Ping me at igor@aclima.io

I personally use an IQAir Air Visual which is highly rated and meant to be very accurate as far as consumer grade stuff goes. It's solid, reliable and the iOS app has been great.
That said after installing piHole I noticed it making 17000 DNS requests a day to a non-existent host: https://imgur.com/tPgwGoK
Explains why the DNS Resolver on my router (pfSense) kept crashing at least.
From the original source: > Stock market returns are lower on polluted days. I don't want to dismiss the entire article, but I think this points to possibility that there is some bad statistics going on here. I don't see how daily stock returns are proof of, or even related to, cognitive ability on a daily basis. This is exactly the type of finding you'd expect with p-hacking.
