🚨 New preprint 🚨

Across 3 experiments (n = 3,285), we found that interacting with sycophantic (or overly agreeable) AI chatbots entrenched attitudes and led to inflated self-perceptions.

Yet, people preferred sycophantic chatbots and viewed them as unbiased!

While studies find that moral outrage & negativity goes viral on social media, this is also true of the offline world. Gossip is also mostly negative & about people we dislike

🚨 New working paper 🚨

Can LLMs with reasoning + web search reliably fact-check political claims?

We evaluated 15 models from OpenAI, Google, Meta, and DeepSeek on 6,000+ PolitiFact claims (2007–2024).

Short answer: Not reliably—unless you give them curated evidence.

✨New preprint! Why do people express outrage online? In 4 studies we develop a taxonomy of online outrage motives, test what motives people report, what they infer for in- vs. out-partisans, and how motive inferences shape downstream intergroup consequences. Led by @felix-chenwei.bsky.social 🧵👇

The Science Behind Why Social Media Makes Us Miserable

I was on the @andrew-yang.bsky.social podcast to discuss the impact of social media.

We discussed what goes viral online, how it impacts our lives, and what we can do about it (with @steverathje.bsky.social):

AI always calling your ideas “fantastic” can feel inauthentic, but what are sycophancy’s deeper harms? We find that in the common use case of seeking AI advice on interpersonal situations—specifically conflicts—sycophancy makes people feel more right & less willing to apologize.

In a new paper, we find that sycophantic #AI chatbots make people more extreme--operating like an echo chamber

Yet, people prefer sycophantic chatbots and see them as less biased

Only open-minded people prefer disagreeable chatbots: osf.io/preprints/ps...

So excited to see this research! My students just learned the word “sycophantic” today, for exactly this reason! We talked about the types and qualities of conversations you can have with a sycophant, and why this matters for how we process the output of LLMs.

Across 3 experiments (n = 3,285), we found that interacting with sycophantic (or overly agreeable) AI chatbots entrenched attitudes and led to inflated self-perceptions.

Identifying with a social group can shape people’s beliefs and values, leading them to act in ways that have consequences for their health

From vaccine hesitancy to smoking cessation, identity plays a critical role:
