Explains a great deal, honestly.

like what? are there more intelligent people? I've anecdotally heard this is a cause for crime reduction as people are less impulsive than they were, in conflict resolution? overall?

don't really know what takeaway I'm supposed to know about

Are you really calling into question the well documented developmental effects of lead in human cognition and behavior

No, he’s asking for someone to expand on their five word sentence that is so generic it can be interpreted to support almost any thesis you want.

The punchline being:

  The findings, which appear in PNAS, underscore the vital role of environmental regulations in protecting public health.

  The study notes lead rules are now being weakened by the Trump administration in a wide-ranging move to ease environmental protections.

  “We should not forget the lessons of history. And the lesson is those regulations have been very important,”

Hopefully next we can help fix mercury in fish, the number one contributor right now is burning coal. Seems like it would be a easy decision.

Coal is mostly sticking around in the US because of federal overreach to keep unprofitable and ancient coal generators going long after anybody wants to pay for the high maintenance.

Last week, a Colorado utility was "respectfully" asking to be able to close a plant:

> TTri-State Generation and partner Platte River Power Authority had a “respectful” but emphatic response late Thursday to the Trump administration ordering them to keep Craig’s Unit 1 coal-fired plant open past the New Year:

> They don’t need it, they don’t want it, and their inflation-strapped consumers can’t afford the higher bills. Plus, the federal order is unconstitutional.

TVA has also been begging to close a money long coal plant for a while now, writing letters to FERC about it, but I can't find the link now.

New coal is far too expensive to build anymore too. Handling big amounts of solid material is expensive, and big old unresponsive baseload is undesirable for achieving economic efficiency.

Even China, which is still building new coal plants, is lessening their coal usage. Personally I think they'll kee some around to continue using influence of Australia, which is one their primary countries for experimenting with methods to increase their soft power.

There is now technical or economic reason to want coal power.

How does misalignment scale with model intelligence and task complexity?
