Where do the numbers come from?

Having read something about self-driving cars actually being a thing now, I wonder how the trolley-problem thing (and whatever other ethics problems come up) was solved in the relevant regulation?

Bryan Caplan: Conformity drives a lot of fertility behavior. The main driver of the Baby Boom really was, “Everyone else is having big families; we should, too.”

Is that just a claim or does he provide evidence for that?

• Except then we started shaming ‘incorrectly’ having children directly.
• We have also continuously raised the bar on what counts as ‘incorrect.’

This is not so obviously correct, or at least the "bar" seems multidimensional. Some decades ago, it was a shame for an unmarried couple to have children, and in particular it was a great shame for a single mother to have children. At least where I live that has changed.

The problem is that the shaming we used to do mostly did have an underlying societal purpose.

This claim would be stronger with some examples.

"Most people who want them all fired would be totally fine paying the extra salaries indefinitely. "

That is likely wrong, but in any case it's just a claim and should be phrased like that.

"Stephanie Murray reports that the village thing can still be done, and in particular has pulled off a ‘baby swapping’ system that periodically pools child care so parents can have time for themselves."

Maybe there is more detail in the linked blog but just from this post it sounds like a reinvention of Kindergarten.

Offering $7,500 total is likely on the high end of what is practical before people start inefficiently gaming the system.

What does that mean? The wikipedia article Child benefit lists several examples of child benefit systems that yield more than $7,500.

The most important fact about politics in 2024 is that across the world, it's a terrible time to be an incumbent. For the first time this year since at least World War II, the incumbent party did worse than it did in the previous election in every election in the developed world. ...

What influence does the exclusion of "years where fewer than five countries had elections" in the graph have?

Does this question require that there is only one big filter per species?
