Some of this is correlation: poorer people live in older buildings closer to highways and let their children get exposed to more lead. I wouldn't be surprised if lead has some causal effect though

The significant factor is that for every 5 ug/ml increase in B-L at age 6, it predicted arrest for any reason for violent crime by 50 percent. That's evidence for a causal relationship. Also worth noting 90 percent of the sample was black, too.

So there is also evidence within a sample of blacks that blood lead levels predict arrest.

Just looking at raw numbers isn't the way to analyze this stuff though. This is what we have statistics for.pic.twitter.com/rNR7QcTDNG

I'm glad that they're trying to adjust for maternal IQ there, but we're still not getting all the way to causation here.

Do you want brain scans or biopsies to actually see if these people had some kind of pathology due to the lead exposure? Cause that's where it looks like you're going
-
The "ever arrested" group here is only 136, they're missing paternal IQ, and even the maternal IQ and SES adjustments may not catch enough of the potential confounding. 1.4 ratio is just too high for a small lead increase like that
-
What makes you say it's too high?
