Every time I inform someone that the abortion-crime hypothesis went bust and point them toward the lead-crime hypothesis instead, it feels like saving a soul...

I really like the lead-crime hypothesis, & find the research compelling. However I asked Steven Pinker about a year ago, directly, & he still thought the hypothesis remains unsubstantiated. (I think he says there are too many causal steps unproven?) I was disappointed.
-
They keep doing large-N quasi-experimental studies that find a link, with a dizzying array of methodologies...

The heavy lifting, banning tetraethyl lead is already done. We don’t have nearly the same blood levels now as 40 years ago.

Lead pipes and lead paint in soil are still problems, even small amount of lead can have big effects
-
Indeed. I should have said ambient levels. A situation like lead pipes or natural lead can create hot spots.

I've always wondered if the increased lead levels Gen-x was exposed to has contributed to the seemingly explosive increase in ASD diagnosis and other related disorders by their children.
-
Increases in ASD diagnosis are mostly caused by an expansion of the definition. I don't think there's a connection to lead.

We are all looking for the 'magic answer'.

Unless you can show that lead exposure affects receptors or inhibits frontal lobe development, the correlation between lead exposure and crime could also be explained by poverty.

Was there any response from Donohue or Levitt about the paper by Foote and Goetz?

I wonder what we do now that might be killing us and it's nearly unknown? I suppose playing football is in that category
