if people are using classified information to place bets, then theoretically others can analyze betting behavior to find signals that reveal classified information.

The two most successful Dem politicians of my lifetime, Bill Clinton and Obama, were both masculine, to be sure. But they had sort of a cool guy masculinity rather than a tough guy masculinity, if that makes any sense? Idk.

3Blue1Brown has a great video on the false proof that all triangles are isosceles, and what excites me about it is that it's pretty accessible to high school students. In fact, it kind of serves as a nice review of triangle congruence rules.

It's worth reading the whole interview in full. It basically verifies that the NYT has spent the past decade-plus doubling down on top-down narratives for coverage, getting more intense over time. Sulzberg personally picked & chose whom the news apparatus would target and whom it would kiss up to.
