The claim, that we have 'normal mortality' in 2023, is bullshit on its face. Even forgetting about covid deaths, the overdose epidemic is killing huge numbers of people. Pre-pandemic, we weren't doing well either, with US life expectancy declines from 2014-16. Excess mortality is the difference between observed deaths and expected deaths.

Observed deaths are easy to count in countries like the US that document virtually all deaths.

In her soft-denialist WaPo column today, Leana Wen claimed covid hospitalizations & deaths are being over-counted. Her evidence isn't any epidemiologic study or model. No, it's the opinions of two clinicians. One of them, Shira Doron, has long advocated against covid protections. CDC no longer updates its estimates publicly, but it last estimated that actual covid death counts are 25% higher than reported in the US. IHME similarly estimates that new death counts are ~25% higher than reported.

I appreciate constructive criticism! I also have plenty of material on this that I didn't use bc of word limits. I think Stanford as an institution deserves much of the blame for the covid soft denialism that happened on that campus. I'll explain... First, I think it should be understood that criticizing an institution can be shorthand for criticizing its owners/managers. If we say something bad about Amazon, we're talking about Jeff Bezos and not Chris Smalls. Same with Stanford, I'm not criticizing students or all faculty.

Okay here goes. I will tell you what happened with the school covid debate and cite actual evidence rather than make things up. Now I'm sure a lot of people didn't chime in regardless of their policy preferences. That's what happens on hot-button issues that engender pushback. But I'll show you how the conversation was dominated by people who advocated against public health measures in schools.

The term eugenics was coined by Galton in 1883. But there were very similar hereditarian ideas circulating in early Victorian England. And some of their main proponents were in the then-nascent field of public health, like William Farr. sciencedirect.com/science/articl… Stateside, this kind of pre-1883 hereditarianism was also taking hold. In the 1870s, Elisha Harris first documented the Jukes family as a case study of 'defective' heredity that the Eugenics Movement would later highlight.
