"Models casting egalitarian societies as crucibles of equality perpetuate the factually uninformed notion that foragers are somehow more noble. Critiques portray egalitarianism as romantic fantasy. Neither characterization is wholly justified."

maybe humans *should* block out the sun so that the machines have to rely on us for bioelectricity, because that way we can still extract natural resource rents in the full automation economy

a notable thing here is that Jin is about as powerful and privileged as you can be - first-tier Chinese aristocracy, basically, super-connected - and that still didn't prevent her from being harassed by Summers
The Harvard Crimson has ID'ed and published the name of a well-known economist who was the subject of emails between Larry Summers and Epstein.
Born in China, she did her B.A. – Ph.D. at Harvard.
The code name that Summers and Epstein used in their emails about her was "peril." What a vile pig.

Hello fellow nerds! The upcoming Australasian Mathematical Psych Conference (AMPC) is going to be on Feb 23-25, and they've just put out the call for abstracts.
Details below. This is one of my favourite conferences and this year it's in Singapore(!!) which should be awesome.

Fascinating study, in line with the general unreliability of LMs at ToM reasoning I've seen.
I expect they'll be unreliable about other propositional attitudes (want, hope, expect, suspect, etc.), and suspect this is bc they're not trained on data that grounds this vocabulary.

Large language models (LLMs) may not reliably acknowledge a user’s incorrect beliefs, according to a paper in Nature Machine Intelligence. The findings highlight the need for careful use of LLM outputs in high-stakes decisions. go.nature.com/48VRpIQ 🧪

How do people flexibly integrate visual & textual information to draw mental inferences about agents we've never met?
In a new paper led by @lanceying.bsky.social, we introduce a cognitive model that achieves this by synthesizing rational agent models on-the-fly -- presented at #EMNLP2025!

shockingly, it can both be true that 1) we should improve labor conditions 2) the workers prefer what they have now to what they had before.

We have a really strong position paper that has been rejected multiple times from arxiv, both CS.AI and CS.CY, because our "submission does not contain sufficient original or substantive scholarly research and is not of interest to arXiv." Appealing has not helped. Any ideas of what we can do?

Everyone has memoryholed this and thus I'm constantly on about it, but *before 2016* antifascism was incredibly unpopular in The Left. It was basically confined to a minority tendency within anarchism. Virtually everyone else wanted a popular front that didn't create splits over kicking nazis out.
Establishment Democrats spent a full year complaining the Left forced them to be “woke.”
But then a left populist, Graham Platner, threatened to win in Maine, so they went right back to trying to cancel someone over old internet posts.
