🚨🚨Excited that our paper (“The nasty neighbor effect in humans) is out Science Advances: Across a series of experiments, including evidence from 51 societies, we investigated whether people favor ingroup members in competitive situations (1/5): science.org/doi/10.1126/sc…

Kahneman: "Irrational is a strong word, which connotes impulsivity, emotionality, and a stubborn resistance to reasonable argument. I often cringe when my work with Amos is credited with demonstrating that human choices are irrational, when in fact our research only showed that

Yes, this is the super smiley face of someone who just signed a book contract with Cambridge University Press! 😁 Provisional title: The economics of language: How Large Language Models can reshape behavioural economics Let me give you a brief overview of what I’m going to

You don’t know this, but people like you more than you think! This paper find a "liking" gap that holds true for everyone from strangers to classmates to coworkers (There is one exception, supervisors, who are accurate about how much they are liked) sciencedirect.com/science/articl…

It's not "only" child mortality that has declined. Infants, children, adults, and the elderly are all less likely to die than in the past. I wrote a brief data insight to explain this.

Social norms can be quite complex, and they can take many different forms. In a new paper at PNASNews, Yohsuke Murase uses a supercomputer to systematically study the evolution of norms. Here you can find the paper: pnas.org/doi/10.1073/pn…

Does astrology work? We tested the ability of 152 astrologers to see if they could demonstrate genuine astrological skill. Here is how the study was designed and what we found (including a result that really surprised me): 🧵

Results from a new massive study (N=1.3 million) suggest that over the last 20 years we have become more conformist. -We are more concerned about what people think of us. -We are more inclined to self-censor. -We are less inclined to defend our beliefs publicly.

What’s the effect of generative AI on learning? “In a field experiment involving nearly a thousand students, we have deployed and evaluated two GPT based tutors, one that mimics a standard ChatGPT interface (called GPT Base) and one with prompts designed to safeguard learning

Intergroup moral hypocrisy such that people were more forgiving of transgressions when they were committed by an in-group member than an out-group member We found evidence of moral hypocrisy among partisans and minimal groups (via Association for Psychological Science): journals.sagepub.com/doi/abs/10.117…

Yeah, right, let’s start preparing the slides for tomorrow’s talk at 6:50am (not joking)

Interesting new paper looking across 10 years of data finds that American's "binding" moral values (loyalty, authority, purity) change with the seasons. Higher in spring & fall, lower in summer & winter. Correlates with seasonal fluctuations in anxiety! pnas.org/doi/epub/10.10…

Want people to be more receptive to your message? Replace “you” with “we.” “You" signals aggression. “We" builds bridges. Inclusive pronouns decrease resistance and boost your persuasive powers.

In a paper, Tatiana Celadin and I suggest adding a motivation for sharing content, e.g. “share because it’s accurate”, “share because I’m outraged” and so on. Interestingly, we found that adding an “endorsing accuracy” button has two positive effects: it decreases the sharing

This is so interesting! 👇

This incredibly fascinating article provides evidence that humans went through a severe population bottleneck. For thousands of years there have been only around 1280 humans on the whole planet. Basically we’re all brothers and sisters. Show this to the racists around.

Automating AI research is exciting! But can LLMs actually produce novel, expert-level research ideas? After a year-long study, we obtained the first statistically significant conclusion: LLM-generated ideas are more novel than ideas written by expert human researchers.

I’ve just released a new paper. The idea arose from a conversation with Daron Acemoglu about the limitations of today’s generative AI systems. 🧵 1/
