Max Kleiman-Weiner @maxkw.bsky.social · 11/09/2026Our newest work unifying game theoretic ideas about the evolution of cooperation with the emergence of computation itself. Self-replicating programs first emerge through random mutation and then spread by cooperating. 1205
Max Kleiman-Weiner @maxkw.bsky.social · 06/08/2026New lab preprint! AI assistants are myopically helpful. Unlike caregivers that want to empower people and grow their long term autonomy, AI assistants interrupt independent thinking and jump right to the answer. 0173

Max Kleiman-Weiner @maxkw.bsky.social · 05/06/2026Excited about our new work measuring multi-turn persuasion in AI-human interactions and how to simulate human persuadability! 070
Reposted by Max Kleiman-WeinerJared Moore @jaredlcm.bsky.social · 05/06/2026LLMs can shift people's beliefs. But most persuasion studies only check beliefs before and after a conversation. We built PersuasionTrace to measure beliefs turn by turn, so we can study how belief updates actually unfold. 2125

But what does it do to continual RL, where agents face one new task distribution after another? We find that past a point, more diversity actually inhibits continual reinforcement learning 🧵 45114

We built the first unified taxonomy of 28 cognitive elements underlying reasoning Spoiler—LLMs commonly employ sequential reasoning, rarely self-awareness, and often fail to use correct reasoning structures🧠 2468
Reposted by Max Kleiman-WeinerKunal Jha @kjha02.bsky.social · 03/10/2025Forget modeling every belief and goal!

Max Kleiman-Weiner @maxkw.bsky.social · 03/10/2025New paper challenges how we think about Theory of Mind. What if we model others as executing simple behavioral scripts rather than reasoning about complex mental states? Our algorithm, ROTE (Representing Others' Trajectories as Executables), treats behavior prediction as program synthesis. 2142
Max Kleiman-Weiner @maxkw.bsky.social · 02/10/2025When values collide, what do LLMs choose? In our new paper, "Generative Value Conflicts Reveal LLM Priorities," we generate scenarios where values are traded off against each other. We find models prioritize "protective" values in multiple-choice, but shift toward "personal" values when interacting. 1100
Max Kleiman-Weiner @maxkw.bsky.social · 01/10/2025Excited by our new work estimating the empowerment of LLM-based agents in text and code. Empowerment is the causal influence an agent has over its environment and measures an agent's capabilities without requiring knowledge of its goals or intentions. 3172
Max Kleiman-Weiner @maxkw.bsky.social · 06/08/2025Claire's new work showing that when an assistant aims to optimize another's empowerment, it can lead to others being disempowered (both as a side effect and as an intentional outcome)! 070

Max Kleiman-Weiner @maxkw.bsky.social · 09/06/2025LLMs learn beliefs and values from human data, influence our opinions, and then reabsorb those influenced beliefs, feeding them back to users again and again.
