Re: Barr is thinking of the future
"All I see is a bunch of correlations without providing evidence of exactly WHY unleaded gasoline and abortion dropped crime rates."
The lead thing is known: lead has a known causal effect on brain chemistry. It wasn't just lead in fuel; countries that got rid of lead paint experienced a similar improvement.
As for abortions, I assume the causal link is that a lot of crime is drug-related, and a lot of people get into drugs because of a shit childhood. One possible cause of a shit childhood is a family that didn't want you/cannot look after you.
