We find that social reasoning such as theory of mind, moral judgment, and social bias is learned from a wide range of data, including literature and customer support. STEM skills (and even social facts) come from a more limited part of the data such as documentation arxiv.org/abs/2606.19625

The Capabilibara project seeks to understand how a language model learns to interpret people's beliefs, emotions, intentions, and everyday moral choices. We trace that ability back to the training data using influence functions and unlearning hcai-lab-gt.github.io/capabilibara/ Find us at COLM!

4. SocialSim workshop: - Role Steering of Language Models for Social Simulations arxiv.org/abs/2608.00023 Finding steering vectors for complex behaviors like social roles is hard. We introduce a new method for finding steering vectors, called Cast Vectors.

3. SocialSim workshop: - No One Wins in Nuclear War: Social Simulations of High-Stakes Military Decision-Making arxiv.org/abs/2608.01868 We introduce the WOPR testbed. Yeah, you get the reference.

2. SocialSim workshop: - AI is Not Ready for Strategic Conflict arxiv.org/abs/2609.16189 We review failure-modes of AI agents that are asked to participate in wargaming exercises, including sycophancy, role collapse, escalation eagerness, etc. We explain why benchmarks are insufficient.

My lab will be busy at COLM 2026! 1. Main conference: - Capability Provenance in Language Models: A Case Study in Social Reasoning arxiv.org/abs/2606.19625 We present a method for answering causal hypotheses about where in a dataset behaviors emerge. We apply our method to social reasoning.

Told Claude not to use the word "quietly anymore. It is now so paranoid that it wrote a computer program that scans every file it creates and the outputs of every program it runs

Anthropic might have discovered something. Or maybe not. Who knows? Not even Anthropic. www.anthropic.com/news/claude-... This is irresponsible science. The proper course of action is to figure out if there is any significance first. They employ scientists. They know better. They chose to do this.

“Experts”. The only interviewed people from MIRI and Palisades Research, which are both going to be highly biased. Journalists: get a variety of viewpoints. That would probably be good journalistic practice.

I reopened the case and now arXiv is telling me the paper requires additional review and revision? Are they in the business of judging the quality of the work now? I think they are just making excuses now.

I submitted a paper to arXiv in April. It was rejected by moderators, despite being accepted to a long-running workshop at one of the most prestigious conferences in the world. Apparently workshop acceptance is insufficient for arXiv? What? The? Hell?

Pure speculation w/o seeing the logs: Claude (not sure what version) would want to bypass the web UI because that is hard for an agent. It apparently wrote a test harness to probe the reservation system’s API. It didn’t see this as hacking as the API was outward facing. Overkill for sure…
