Could it be that there are other pollutants that could cause similar issues? Some countries have banned lead even before the US, but crime rates are still growing(Brazil, for instance). Poverty alone does not explain this. There are countries just as poor (or more), with corrupt police forces and that do not have the same issue with violence.

Maybe it has to do with the drug cartels or being in war zones? I don't think the study was trying to say that lead is the only factor in crime.

There are probably dozens of factors. Some societal, some environmental. It's not like being exposed to lead makes everybody into a criminal either.

Recent study showing that air pollution can impact intelligence equivalent to the loss of a year of education. https://www.theguardian.com/environment/2018/aug/27/air-pollution-causes-huge-reduction-in-intelligence-study-reveals https://www.theguardian.com/environment/2018/aug/27/air-poll...

  A year of education is a useless metric. Staying one more year in college does not make you smarter. Junk article.

  It's very hard to separate the effects of airborne lead from other air pollution, since they tend to exist in the same places. I wouldn't be surprised if the lead is the cause of both.

  Kevin Drum is an absolute shill for LCH. There was a study in New Zealand that, if you actually read the paper, unambiguously fails to support the LCH. What was the headline for the article he wrote about it? "New Zealand Study Provides More Support for Lead-Crime Hypothesis" https://www.motherjones.com/kevin-drum/2017/12/new-zealand-study-provides-more-support-for-lead-crime-hypothesis/ https://www.motherjones.com/kevin-drum/2017/12/new-zealand-s...
