@dantheclamman wow, and the decline is continuing exponentially through today, looks like
@petrelharp @dantheclamman Yep, like radioactive decay

The study from Cerling et al. I saw Thure Cerling talk about his work when I was a grad student, fascinating stuff! https://www.pnas.org/doi/10.1073/pnas.2525498123
@dantheclamman Nothing about environmental lead and crime, which appears to be a thing...

@JSMuellerRoemer @dantheclamman "Elder Millenial" Is the term you are searching for.

@JSMuellerRoemer @dantheclamman LMAO - embrace it with me! With age comes wisdom.

@Sassinake the paper actually explicitly calls this out in a way I rarely see in a discussion section. very powerful and kind of chilling

@dantheclamman @JDGeoShack dunno, I feel with age comes anger and rage against capitalism and conservative politicians (i.e. all that aren’t on the very left end of the spectrum these days, which is basically the 90s center left). But maybe that’s not about age, more about a system hellbent on ending humanity?

I know I'm a broken record (or looping GIF) on this, but a large reason Pb levels aren't even lower is Avgas, the 100-octane gasoline fuel burned in virtually all reciprocating-engine aircraft, which still contains tetraethyl lead. -

@martinvermeer @dantheclamman Truthfully, this would be very hard data to draw any conclusions from. There are just too many other factors. For instance, the shift from mostly human manufacturing to mostly robotic manufacturing (which began happening at increasing scale post WWII) the stagnation of wages are going to drive crime. Also the CIA selling arms to Iran to buy drugs from Noriega to dump on US streets to increase crime as a way to attack minorities. Too many factors. Hard to isolate.
