Question for any IQ skeptics here (e.g. "it just measures your ability to take tests" or "it just tells you how rich your parents are"): what's your response to studies like this? Is there anything that can be said about the effect of lead on cognitive function? Why might IQ be a good measure of lead-induced stupidification, but unreliable for literally anything else?

Does everybody in the country get an IQ test in school? Can we just look that up in the public records?
It sure would be useful if it was public and universal. For tracking the effects of lead poisoning for one. Or just factoring it into any big study. We might find something unexpected.
Studies like these always make me wonder what the equivalent of this today. Microplastics? Carbon? What else?
And maybe some PFAS? We don’t have great data, and PFAS isn’t reliably disclosed in products. (Also, surely different perfluorinated chemicals have different effects.)
I'd like to point out that, although it is illegal to put lead in water supply lines in the US, there is a loophole that allows it in hot water lines. As a result, for certain fittings, most big-box hardware stores only sell the leaded variants, and label them "hot water heater supply line" or something similar.

Glass or stainless steel would be a better choice (especially for storage).

There’s no BPA, but there have been “cousins” of BPA created that essentially are just as, if not more, harmful
