There’s sort of no point in discussing this article since the full text is paywalled. The Gizmodo summary seems to suggest that it’s mostly just a meta review plus some extrapolation: they averaged some studies to find the typical effect on mental health and then multiplied it by all the lead exposure in the country. I’ll suggest an interesting article to read instead. I don’t have the expertise to evaluate if it’s true but it is a good depiction of where p-hacking and correlation-causation mixups could lead. https://www.cremieux.xyz/p/who-gets-exposed-to-lead https://www.cremieux.xyz/p/who-gets-exposed-to-lead
