How do humans keep inventing tools and technologies that no single person could create alone? Our new preprint, led by @anilyaman.bsky.social & @ts-brain.bsky.social shows that semantic knowledge guides innovation and drives cultural evolution. 🧠📘 arxiv.org/abs/2510.12837

We're psyched to discuss all things disgust in our upcoming conference on Disgust Across Borders! 🦠 Our 2nd (online) keynote is Paul Rozin who will address a fundamental question in Disgustology: "Is disgust a unitary emotion?" 📍 @iast.fr Toulouse 🇫🇷 | Dec 4–5 👀 Stay tuned at tinyurl.com/2tprm9cn!

🚨New paper led by Lei Fan, with Florian van Leeuwen, @hirotakaimada.bsky.social, and @joshtybur.bsky.social, out in Cognition & Emotion: 🔗 doi.org/10.1080/0269... In two preregistered studies from Japan 🇯🇵 , we find that anger relates to confrontation while disgust to gossip and social exclusion.

🦠 Hi disgust nerds! Our 1st keynote at Disgust Across Borders is Caroline Amoroso (@cr-amo.bsky.social, Univ. of Virginia). She’ll dive into evolution & ecology of infection avoidance — how organisms detect, avoid, and resist pathogens. tinyurl.com/2tprm9cn 📍 Toulouse 🇫🇷 | Dec 4–5 👀 More 🔑🗒️ soon!

In an online study with 3,371 participants from 13 societies, Jin et al. found that perceived societal honour norms predicted both greater competition and cooperation. @shuxianjin.bsky.social @ayseuskul.bsky.social www.nature.com/articles/s41...

💙New paper!💙 How is knowledge transmitted across generations in a foraging society? With @danielredhead.bsky.social we found: In BaYaka foragers, long-term skills pass in smaller, sparser networks, while short-term food info circulates broadly & reciprocally academic.oup.com/pnasnexus/ar...

Why do societies reliably develop strikingly similar traditions like dance songs, hero stories, shamanism & justice institutions? In a new BBS target article, I propose a theory for such "super-attractors" + cultural evolution more broadly. Now open for commentary: www.cambridge.org/core/journal...

📣 New registered report in @nathumbehav.nature.com with Ivan Soraperra, @jonathanschulz.bsky.social, and Shaul Shalvi: rdcu.be/eAcMA With data from 7,978 participants in 20 countries, we find that information about negative externalities promotes prosociality, especially in guilt-prone individuals.

📣 New registered report in @nathumbehav.nature.com with Ivan Soraperra, @jonathanschulz.bsky.social, and Shaul Shalvi: rdcu.be/eAcMA With data from 7,978 participants in 20 countries, we find that information about negative externalities promotes prosociality, especially in guilt-prone individuals.

A Registered Report of 7,978 people in 20 countries by @cmolho.bsky.social et al finds that decision-makers willfully ignore inconvenient information. Information about the negative consequences drives prosociality, especially among guilt-prone individuals. www.nature.com/articles/s41...

Through experiments and simulations, this study shows how individuals learn to learn from others, dynamically shaping the processes involved in cultural evolution. @davidschultner.bsky.social @bjornlindstrom.bsky.social @lucasmolleman.bsky.social www.nature.com/articles/s41...

Here, weird guy from X, I fixed it for you: "If a scientific society wants to be welcoming to [...] students & researchers [from the Global South], does it make sense to hold its next annual conference in a country that's notorious for [being located in the Global South]?" The answer is Yes.

I had the most incredible opportunity to attend the Toulouse Summer School in Quantitative Social Sciences at @tse-fr.eu and learn from @lfitouchi.bsky.social , @cmolho.bsky.social & @jorgeapenas.bsky.social on the "Evolution of Human Sociality" Toulouse was warm and welcoming, so was TSE !!

Many thanks to HBES for this recognition and congratulations to Rising Stars @mohammadatari.bsky.social @danielredhead.bsky.social @juliastern.bsky.social 💫

Springer-Nature launched a series of "Discover" journals that closely mimic MDPI titles -- sharing *identical* journal names, and likely similar business model. What is going on, and why researcher will - as always - fall for it? A 🧵 the-strain-on-scientific-publishing.github.io/website/post...

#HBES2026 will be a joint meeting with the Cultural Evolution Society in Rabat, Morocco: CES is May 11-13, HBES is May 13-16, with one day of planned overlap. It’ll be a great chance for cross-pollination between the two evolutionary societies. Come for one conference, stay for both!

Four large Dutch universities, including Leiden University where I work, have decided to throw international psychology bachelor programs under the bus in an effort to appease the rightwing government. Here's my blog why this is a terrible idea. eiko-fried.com/cutting-inte...
