By popular demand, I just put together this index post to bring together all the papers in our 𝐓𝐡𝐞𝐨𝐫𝐲 𝐨𝐟 𝐀𝐩𝐩𝐫𝐨𝐩𝐫𝐢𝐚𝐭𝐞𝐧𝐞𝐬𝐬 sequence together in a single list. It includes both the social/cognitive science foundations and the AI governance applications.

New paper: “A Theory of Appropriateness That Accounts for Norms of Rationality”

Agent-based models of social order work better when agents act by predictive pattern completion from prefix (culture/context) to suffix (action) than when they act through expected value maximization

Come find us at #NeurIPS2025’s poster session today! Our Research Analyst @ChandlerDSmith will present ‘Evaluating Generalization Capabilities of LLM-Based Agents in Mixed-Motive Scenarios Using Concordia’. More details below:

@alexUnder_sky @drimgemp we turned off the autoloop... really sorry for the inconvenience!

We're running back our AAMAS 2025 tutorial at SAGT in Bath, UK! If you're interested in general evaluation of AI agents, you should check out our tutorial today (Sep 2nd)! The website is here https://t.co/HAqiPcQFAj, including some draft notes!

[Manfred Diaz @linuxpotter]

@shaneguML Congrats, Shane! I know how much you've waited for this!

[Joel Z Leibo @jzl86]

Introducing Concordia 2.0, an update to our library for building multi-actor LLM simulations!! 🚀

We view multi-actor generative AI as a game engine. The new version is built on a flexible Entity-Component architecture, inspired by modern game development.

[Yoram Bachrach @yorambac]

How should we rank generalist agents on a wide set of benchmarks and tasks? Honored to get the AAMAS best paper award for SCO, a scheme based on voting theory which minimizes the mistakes in predicting agent comparisons based on the evaluation data. https://t.co/iV2pjwDxoU

[Joscha Bach @Plinz]

It may be time to develop AI programming languages. Code generation must be optimized for guiding models in exploring solution space and ensuring correctness, not for human comprehension. Code specification must optimize synchronization between human intention and AI

[Manfred Diaz @linuxpotter]

@AAMASconf 2025 was very special for us! We had the opportunity to present a tutorial on general evaluation of AI agents, and we got a best paper award! Congrats to Marc, @kateslarson, @qberthet, @drimgemp and the rest of the team!

[Manfred Diaz @linuxpotter]

If you're attending @AAMASconf 2025 and are interested in general evaluation of AI agents, you should check our tutorial on May 19th!

The website is here https://t.co/aFllw5KRYc, including some draft notes!

Co-organized with Marc Lanctot, @drimgemp, and @kateslarson

@SigalSamuel @jzl86 @WilCunningham @sebkrier Thank you!

[Manfred Diaz @linuxpotter]

@breandan I'm really sorry to hear this Breandan. Stay strong!

[Manfred Diaz @linuxpotter]

@jzl86 @sebkrier @sindero and @WilCunningham 😉!

Announcing our latest arxiv paper:

Societal and technological progress as sewing an ever-growing, ever-changing, patchy, and polychrome quilt
https://t.co/psF7mHWVel

We argue for a view of AI safety centered on preventing disagreement from spiraling into conflict.

You should be so lucky to have people throughout your research career that you can openly bounce ideas to and from - especially if they complement your strengths in your areas of weakness - it is a rare and precious gift.
