@Ugo_alves Yes absolutely it can. I agree social media is a primary method of diffusion of behaviors like virtue signaling. We also have a social media environment that you can play with to simulate this in Concordia github.com/google-deepmin…

@locross I don't want to extrapolate too much, but could this setup be used to study the mechanism in which (my hypothesis is that) social media augments and makes more prominent virtue signaling and status-seeking behaviors?

Ever wonder why we drop $1,000s on a Chanel bag or queue for ages for a Labubu doll? Status signaling drives a lot of human behavior, but how certain things become potent status symbols has a remained a big puzzle in social science In our new paper we: 1. Synthesize the literature on this topic and propose a generative model of status signaling through the theory of appropriateness: people imitate what "someone like us" is supposed to want, display, and value 2. Show that we can simulate the theory to demonstrate how status symbols emerge with LLM-agent societies in Concordia @jordigraumo @WilCunningham Sasha Vezhnevets and @jzl86

We generalize the same mechanisms beyond luxury consumption and procedurally generate social signaling scenarios for political allegiance, altruism, and arbitrary conventions. For example: with a social life, agents were more likely to choose a large public donation over a smaller anonymous one

Check out our latest paper! LLM-based social simulation is promising — but generic persona prompting collapses toward the “average human,” failing to capture the rich distribution of real behavior. In Persona Generators, we introduce: • A two-stage pipeline: 1.Generate thin personas that maximize coverage over diversity axes (explicitly sampling off-mode traits) 2.Expand each into a thick descriptive persona in parallel for scale • LLM-guided evolution of the generator itself (AlphaEvolve-style optimization of code + prompts) to hill-climb on diversity
Davide Paglieri@PaglieriDavide

🧬 New paper from my internship at @GoogleDeepMind We introduce Persona Generators: functions that generate diverse synthetic populations for arbitrary contexts. We use AlphaEvolve to optimize the generator code, hill-climbing on diversity metrics — not just likelihood — counteracting the mode-seeking behavior of LLM sampling for agent-based simulations. 🧵👇1/

finally announcing i’ve started humans& w/ amazing friends @gharik & @YuchenHe07 & @TheAndiPenguin & @noahdgoodman & many other world-class folks. we're optimists: it’s possible to rethink how we build ai, to empower people to accomplish more together tldr: love is all you need
humans&@humansand

Today we introduce humans&, a human-centric frontier AI lab. We believe AI can be reimagined, centering around people and their relationships with each other. At its best, AI should serve as a deeper connective tissue that strengthens organizations and communities

Some exciting job opportunities are now opening up on my team studying the post-AGI world. If you know someone who would be a great fit for this, please pass this along!
Iason Gabriel@IasonGabriel

🚨Exciting new opportunity🚨 Come and work with me and a fantastic team @GoogleDeepMind exploring the political, economic, social and cultural impact of advanced AI technology, including AGI and beyond! The details and application link can be found below!

[1/9] Excited to share our new paper "A Pragmatic View of AI Personhood" published today. We feel this topic is timely, and rapidly growing in importance as AI becomes agentic, as AI agents integrate further into the economy, and as more and more users encounter AI.

What mechanisms do LLMs use to perceive their world? An exciting effort led by @wesg52 @mlpowered reveals beautiful structure in how Claude Haiku implements a fundamental "perceptual" task for an LLM: deciding when to start a new line of text.
Wes Gurnee@wesg52

New paper! We reverse engineered the mechanisms underlying Claude Haiku’s ability to perform a simple “perceptual” task. We discover beautiful feature families and manifolds, clean geometric transformations, and distributed attention algorithms!

1/x Our new method, the Inter-Animal Transform Class (IATC), is a principled way to compare neural network models to the brain. It's the first to ensure both accurate brain activity predictions and specific identification of neural mechanisms. Preprint: arxiv.org/abs/2510.02523

I told my parents that I’d like to drop out of my cs phd program at Stanford a few months back. They didn’t let me, we’re asian :) So I graduated and started @moonlake. @sharonal_lee and I saw urgency, and opportunities. Excited to share that we raised a 28 million dollar seed round to build the future for simulations and games. Grateful for the angels @naval, @goodfellow_ian @stevechen, @JeffDean @rauchg, @emerywells, @JaredLeto, @chrlaf, alongside many more, and the venture partners that we are fortunate to work with: @moislamvc, Shaun Johnson, @chrmanning, Artem Barsukov, Elvin Hao, @mercebent, @veelarco and William Freiberg. If you're a founder and you're not partnering with them, you're making a big mistake. Check out what we're about 👇

Moonlake@moonlake

We raised $28M seed from Threshold Ventures, AIX Ventures, and NVentures (Nvidia's venture capital arm) —alongside 10+ unicorn founders and top AI researchers— to build reasoning models that generate real-time simulations and games. Models are bottlenecked by practical simulations that can act as Reinforcement Learning environments. Human self-expression is bounded by tools that let us create alternate realities. At Moonlake, we are building a future where anyone can create interactive worlds, bring their child-like wonder to life, learn within them, and most importantly, share experiences with people we care about.
