A little while ago, my parents' cat Bridget went missing. As the weeks dragged on, they became extremely worried. My dad devised a way to distract himself: he began to paint Bridget's adventures, imagining her travelling through time and popping up in some of art and music's most iconic scenes.

I finally tried out {priorsense}📦 with #Stan #rstats and it's awesome! Fed it a simple model I use for teaching, and found some (minor) prior-data conflicts. The powerscale_plot_dens() function really helps in understanding how "bad" the conflict is.

Likening PhD holders to a (non-functional) algorithm is a form of dehumanisation & anti-intellectualism that is a bellwether for contemporary fascism. Essentially it's a typical — if not the archetypal — first step towards fascism: to dehumanise, deskill, defund, and, ultimately, fire the academics.

There’s an intersection with research on reading where there’s a suggestion that more accurate understanding of the information in text requires ‘active’ processing but text written to be easy to read can induces a feeling of understanding that reduces active questioning approaches to text

To return to the topic of the video then, I wonder if what @acollierastro.bsky.social is reacting to is the experience of having physics, for the first time in a long time, (fake) pulled by LLMs into that plain-language-breeds-contempt space that the humanities have been in for a long time.13/
"Online Rent-a-Sage" Bret Devereaux (@bretdevereaux.bsky.social) reposted reply parent
But without an esoteric language in which a field must operate, the plain language works to conceal that and encourages the bystander to hold the field in contempt - @acollierastro.bsky.social hits this when she talks about how little value these folks had for art, until a machine could do it. 10/
