For all those commenting on 'aren't more polluted areas just more criminal due to other factors", as far as I can tell the researchers examined crime rates for the same place and find correlation with whether there was more Ozone and PM 2,5 on a particular day or not. So they are not comparing clean air neighborhoods to highly polluted neighborhoods, but the same neighborhood on different days. https://www.sciencedai…

The main problem I see with this study is that it could be confounded by the fact that high air pollution areas have other problems too that could be causing the bad behaviour instead, like overcrowding, noise, frustration at slow traffic, etc.

I agree consider Singapore, massive pollution problems but one of the safest countries in the world.

Eating prison for also associated. Correlation does not equal causation.

> Correlation does not equal causation Say what? You should write these scientists and explain, I'm sure they've never heard of this concept!

Given some of the other statements they made, they've at least forgotten it. Most of us often forget.

I wonder if there are specific components of the polluted air that have effects, like human body odor, pheremones, or just allergens.

lol, https://www.tylervigen.com/spurious-correlations anyone?

Reminds me of the organic food movement and # of autism correlation which is useful vs antivax arguments (as normally antivax people are heavy into organic [not that theres anything wrong with organic, yum!])

That may well be true. In this case, the link was to an article, not a study. The article clearly implies causation.

If you read the article: > Correlation is not causation of course (there may, for example, be a third variable affecting both pollution and crime) and the authors are cautious not to speculate about the precise mechanism by which contaminated air might lead to more rapes or robberies.

From the paper's abstract, though, "The results suggest that a 10% reduction in daily PM2.5 and ozone could save $1.4 billion in crime costs per year, a previously overlooked cost associated with pollution." This statement sounds like it's implying a causal relationship to me.
