Some background (I live in Dunedin the city that this study is based) - this particular study is part of a much larger multi-disciplinary study where every child born in one year has been followed throughout their life - they are 45 years in at this point - it's one of the very few such comprehensive studies worldwide
So you're seeing one profile of lead exposure (the one experienced by people born 72-73) over their lifetimes - NZ removed lead from petrol later than the US did, however Dunedin is a relatively small city (~120k people) without giant freeways/etc so lead levels are likely lower than those in some places in the US
Here's the study's home page

- dmix 9y agoBoth the lead levels and population size were far smaller than the original study. But regardless they failed to find a solid correlation between the two. It's disapppointing the author presents his own reinterpretation with such certainty given that context but I really dont expect much from a publication like MotherJones who are known for their shameless polarized position taking and bias friendly reporting. Even viewed in isolation this author was entirely unconvicing in that regard.
