My analysis of a paper concluding obesity could be protective against mortality in dementia patients.
This paper was more thoughtful than I initially expected, testing & ruling out:
- reverse causality
- survival bias
- collider bias
This one made me think! 👇
New study says obesity might reduce the risk of dying from dementia.
Is this a real signal, or just more headline noise we should disregard?
The answer is not as obvious as it may seem, says Dr. @ArielleSelya. acsh.org/news/2026/10/26/wai…

Yet the government dutifully collects unused opioids from people who haven’t the slightest clue that they’ll probably not get new ones when they really need them. It’s like giving back any unused portion of your paycheck.

Today at 5: Anthropologist @eweissunburied on why the wokies endorse some patriarchy.
"A dangerous mixture of good intentions and harmful ideology" is burying America's past, says anthropologist Elizabeth Weiss @eweissunburied.
Museums are now presenting native American creation myths as history and reburying 12,000-year-old human skeletons to satisfy activists.
Meanwhile, critical research on the first people in the American Southwest has largely ground to a halt courtesy of progressive politics.
Tomorrow Dr. Weiss joins @JonEntine, @DrLizaMD and me to make her case.
