lookinforcars1 saidThere's also been theories floated around in the past that crime went down when ABORTIONS became cheap/ free and legal( poor, minority etc getting abortions = less " supply" to engage in criminal activity when they would have been " of age". I believe it was addressed in the book Freakonomics Correlation does not = Causation. Interesting article though.
I not only always thought albeit intuitively that was horseshit but it also raised a red flag for me on anyone who'd argue it. I was pleased to see that issue addressed in the article which I also found to be an interesting read about what sounds a plausible explanation.
An issue I have with it however might be the state by state stuff, because wouldn't weather systems with their wind currents determine that, seems pretty overlapping and therefore the research overreaching. I'll never forget that beautiful sunset we had in Florida when Mt St. Helens erupted. And it doesn't say they checked area by area but state by state so I'm a little suspicious of that aspect of their study.
Although, and just thinking this as I posted, wasn't there a time when we were dealing with fumes directly at the gas pumps? Because that might localize it to discount weather systems.
