Presented my recent paper “Predicting Module-Lattice Reduction” with Léo Ducas and Paola de Perthuis at Asiacrypt 2025 in Melbourne. A great way to wrap up the year! Merry Chrissy everyone :)

The Bondi beach attack is the deadliest mass shooting in Australia in decades, after the 1996 Port Arthur Massacre. The shooting is a heinous attack on the Jewish community. Authorities should invest substantially in efforts to counter threats.

More quality evidence is emerging that "pro-environmental behavior" is not a coherent, unitary thing. One behavior is not a proxy for all other behaviors. www-sciencedirect-com.proxy.uba.uva.nl/science/arti... Blankenberg et al. 2025 1/3

Very grateful that our paper was awarded ISCON’s Best 2024 Paper in Social Cognition!! Huge thanks to the fantastic team: Ben Stillerman, @bjornlindstrom.bsky.social , @leorhackel.bsky.social , Damaris Hagen, Nils Jostmann, and @davidamodio.bsky.social 🎊💐

🌱 Higher perceived complexity around climate mitigation was associated with lower policy support and intentions to act. Check out @saarataavila.bsky.social's awesome new paper on how perceived complexity can be measured (subscales: effectiveness uncertainty, trade-offs, and goal conflict).

🎊 New paper out! In this @cp-trendscognsci.bsky.social Forum, we (with @lucasmolleman.bsky.social and @bjornlindstrom.bsky.social) summarize how reward learning can lead to adaptive social learning. We also explore the broader consequences for cultural evolution: www.cell.com/trends/cogni... 🚄

💥 Our new paper (with ‪@lucasmolleman.bsky.social and ‪@bjornlindstrom.bsky.social‬) is now out in @nathumbehav.nature.com‬ 🥳 www.nature.com/articles/s41... 🧠 Here, we advance a novel RL account—the Social Feature Learning (SFL) model—that explains how people learn to learn from others! 🤝 🧵👇

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...

In our now published letter in @pnas.org, we raise two wider issues for behavioral science: 1) Intentions are poor predictors of behavior 2) Effects on intentions need not generalize to effects on behavior We join calls for researchers to measure actual behavior: www.pnas.org/doi/10.1073/...

Very happy to share the first scientific publication of our microfibre-citizen science project! 🥳😊 How does participating in citizen science impact people’s views and behavior? See thread by @annabosshard.bsky.social for more details on the psychological outcomes of our study. More to come soon…

Washing synthetic clothes is a major source of microplastic pollution. Citizen science can help understand which behaviors & materials cause most emissions, like through at-home data collection. We asked: Does participation also boost pro-environmental motivation? 🧵 pubs.rsc.org/en/Content/A...

Strikes are beginning, because the cuts are dire. This story has many twists and turns, but in short, Dutch universities are proposing to sacrifice certain programs like our Psychology BSc in English to hope to appease the nationalist government. This isn't done yet. www.folia.nl/en/actueel/1...

Excited to join Bluesky! I’m a PhD candidate at CWI and QuSoft, working on quantum & classical algorithms for post-quantum cryptanalysis 🔑. Check out our recent paper here: arxiv.org/abs/2503.23238. Looking forward to connecting with others in quantum computing, cryptography, and beyond!

🚫 Why does #TheHague #fossilfuel advertising ban matter to mitigating #climatechange? Our colleague Thijs Bouman & co-authors Jan Willem Bolderdijk & Keith Smith explore the impact of the bold initiative beyond its symbolism in a new paper: www.nature.com/articles/s41... Here's a short 🧵:

Climate action means taxing the rich. We must "strengthen equality and redistribution through suitable taxation policies, basic income and job guarantees and by setting maximum income levels, expanding public services and rolling back neoliberal reforms" www.nature.com/articles/s41...

🚨 New preprint out! 🚨 How do people make moral judgments as third parties? 👀 We show how two motivations—inequality aversion (fair = moral) ⚖️ and the common-is-moral heuristic (frequent = moral 👨‍👩‍👧‍👧—interact to shape evaluations 🧵👇 📄 osf.io/preprints/ps...

❓Do Left-wing Voters #Cycle more than Right-wing Voters? 🚲 🚲 🚲 Read our short paper in Findings ➡️ findingspress.org/article/1294...

🚨 New preprint! 🚨 We analysed over one million actions reported in the AWorld app, the UN's official platform for individual action on climate change: osf.io/preprints/ps... This was an exciting collaboration with @kristiansn89.bsky.social, Jan Bauer, Laura Basconi, & @cameronbrick.bsky.social 🧵👇

If you're interested in post-growth economic thinking, this newly published article will be right up your street. It was a big pleasure to work on it with such a fantastic group of co-authors. Check it out here: www.sciencedirect.com/science/arti...

My lovely colleagues at CAST are advertising 5 PhD funded places! Couldn't think of a more wonderful team to do your PhD with ✨ 🌎

Emotions are reactions to situations we encounter in daily life. In our new paper in Psych Review (psycnet.apa.org/fulltext/202...; with @oisinryan.bsky.social and @fdabl.bsky.social), we take a first step towards building a generative model for emotion dynamics based on this simple principle 1/4

🎉 Embrace sufficiency 🎉 Sufficiency has great untapped potential to accelerate the energy transition. In our new paper, we review key barriers, sketch how various actors can help overcome them, & draw broad lessons from transition studies for systemic change: www.sciencedirect.com/science/arti...

The Veganuary campaign, which encourages a plant-based diet in January, has successfully reduced meat consumption over the long term, with over 80% of participants reducing their intake to half or even more after six months. .

“It’s a constant tension between the scientifically illiterate and the politically clueless” Scientists don't understand how policy works, and decisionmakers often don't understand the science, and there is agreement that we could and should do better. www.nature.com/articles/d41...

🚨 New preprint 🚨 Are climate scientists less trusted than scientists in general? 🤔🌍 Yes, we find evidence of a significant trust gap between climate scientists and scientists in general. 👇🧵 osf.io/preprints/os...

🌍 Thrilled to share our new preprint and the first part of my thesis! Using machine learning, we analyzed data from 55 countries to uncover key individual and nation-level predictors of climate change beliefs & behaviors. Let's dive in! 🧵 1/12

New paper (& my 1st PhD paper) 📢 “I would even find it almost liberating if certain things were simply no longer allowed.” 🚫 Curious what different groups involved in the ‘farm-to-fork’ food chain think about #microplastics in the human food chain & potential solutions? 🥬🥩🧃

Dorothy Bishop lambasts world’s oldest scientific academy as she quits in protest “I’m not willing to treat Elon Musk ‘collegially and with courtesy’,” she says. www.researchprofessionalnews.com/rr-news-uk-c...

Bit shocked by how quickly political discourse is degenerating in this country 😳

Analytic thinking is related to lower belief in conspiracies. So can analytic thinking decrease belief in conspiracy theories? We don’t really know, as the one set of studies in support of this does not seem to replicate. With @marijapetrovic.bsky.social, @vukasin.bsky.social #socialpsyc #PsychSci
