- Definitely seems plausible for some, seems unlikely to be the dominant narrative for most. Strategic ambiguity allows for multiple reasons under the same banner.
- Another is extreme parochialism -- some people want a country where people like them are in charge, and are willing (and excited) to violently dominate or remove those in their way. Govt corruption and incompetence is a price they're willing to pay.
- That's why pluralistic appeals to the public good and human decency aren't working -- the dominant narrative too many have bought in the US is that there are two sides that are incompatible, and therefore one must triumph over the other.
- Meanwhile the corruption is just absolutely staggering. They are literally looting government coffers. www.bbc.com/news/article...

- I got into an argument with someone back around 2020 when I said the “thin blue line” flags were fascist symbols and should be actively condemned (they argued it was just supporting local cops). Well, here we are.
- (I know, as if uncritically and unreservedly supporting cops isn’t already halfway to fascism)

- A neat paper I worked on, begun over 2 years ago when our concerns were more myopic, was just published today. It came out an excellent set of workshops at the Santa Fe Institute, led by the indefatigable Joshua Garland. The gist: sometimes inefficiency is good for you www.nature.com/articles/s44...
- Reposted by Paul SmaldinoOne court decision, two different headlines. Guardian on the left, NY Times on the right. Which one more directly conveys information and the stakes to the reader?
- Looking through Norbert Wiener's 1950 book "The Human Use of Human Beings," just now, this 2-paragraph passage jumped out at me from the first chapter. Extremely relevant to our troubling times.
