Haven't watched Z's video, but I'd also note I'm deeply sceptical that the nerd/jock distinction was ever real past maybe the 90s.

In my own school (and those of all the people I've discussed it with), if you were in advanced classes, you almost always played a sport. Even geeky interests - like video games, some anime (Yu-Gi-Oh, Pokemon), and to a lesser extent comics - were incredibly popular. There were cliques, but those cliques were normally personality and friend based rather than academic vs. sport. If there were a divide, it was between those who were socially skilled and those who were not, but that didn't neatly map onto whether you were smart or not.

Even as a kid, I mostly thought of the nerd/jock stuff as being a marketing ploy, rather than reflecting my own experiences. Which isn't to say you wouldn't get people identifying as nerds or geeks, but to say that the actual social reality didn't seem to match.

Is this what Brits felt like with Dominic Cummings?

The rationalists - sometimes making me question my commitment to prison abolition. Actually, not frequently enough, considering how few are arrested.

The Wikipedia article on the Human Biodiversity Institute cites the term human biodiversity as becoming a euphemism for racism sometime in the late 90s and Marks' book is from 1995, so there was apparently a pretty quick turnover. Which makes me wonder if hijacking or if independent invention. The article has a lot of sources, so I might mine them to see if there's a detailed timeline.

I feel like you would use an extended modifier instead: Die kindische und katastrophale von Rationalisten gebrauchte Sprache. Or maybe something like "die kindische und katastrophale Rationalistensprache". Not sure though. This is pushing the limits of my B1 German though.

Yes it is. I'm just waiting for the Knowledge Fight boys to have a podcast on this deposition.
