Progress: France bans killing day-old chicks, sparing 50 million chicks annually! The alternative, in ovo sexing, has "an extra cost of 1 euro cent per box of six eggs." If the rest of the world adopts it, we could spare seven billion more chicks.

I just subscribed to Future Matters, a newsletter about developments affecting the future of all sentient life (no biggy), which was apparently launched yesterday futurematters.substack.com/?utm_medium=we…. This is like my third ever tweet so it must be important.

In psych studies, people prefer to kiss a celebrity crush in 3 weeks than in 1 week so they have longer to look forward to it. But I'd have always chose 1 week in case the Queen died before we got the chance. RIP Your Majesty. #RIPQueenElizabeth #QueenElizabethII #QueenElizabeth

Despite my towering scholarly achievements, I have long been the least cited of 6 Joshua Lewis's on Google Scholar. But no longer. Did I over take someone, you ask? Let me answer thus. Joshua Lewis from New York City Medical College, to you and your first 2 cites, welcome.

This is the strongest evidence we have that open science practices (pre-registration and open materials) lead to highly replicable findings. As scientists, we ought to update our beliefs from evidence. Is it time to mandate pre-registration for confirmatory hypothesis testing?

Would it be worth it if a million new people started campaigning for better climate policy? What about one person? If you answered "yes" then "no", our new pre-print says you might be biased osf.io/preprints/psya… Lucius Caviola Shalena Srna @matti_wilks Christoph Winter Erin Morrissey

We’re looking for a Research Fellow and Junior Researcher (RA) to investigate the psychology of global catastrophic risk and effective altruism. Work with Joshua Lewis and myself, either at NYU or remotely. Please share! eapsychology.org/jobs

New preprint and blog post! We explore the social disincentives of warning about unlikely risks. Many people are reluctant to warn about large but unlikely risks because they could look bad if the risk doesn’t occur 1/5

New preprint! Co-led with Lucius Caviola, along with Joshua Lewis and Christoph Winter, we show that reputational concerns hinder people's willingness to warn others about severe, yet unlikely, risks. osf.io/preprints/psya…

Will disagreement about AI sentience lead to war? AIs could become sentient and worthy of moral concern (similar to humans). But people will disagree about it, potentially causing conflict. In a new post series, I explore the dynamics and risks of the upcoming AI rights debate🧵

How can nonprofits effectively present cost-effectiveness information? 🎯 A brand-new research paper by Joshua Lewis and Deborah Small finds that people use impact cost information (for example: $1 to provide a meal) as a target for how much they should donate. Brief summary🧵

Specialized neural networks & general LLMs outperform humans at predicting personality item correlations; specialized models & aggregated expert predictions are most accurate on most measures. Philipp Schoenegger Lucius Caviola Spencer Greenberg 🔍 Joshua Lewis nature.com/articles/s4427…

New paper published (with Spencer Greenberg 🔍, Lucius Caviola, @Joshdalewis, and Grishin)! We find that LLMs and non-LLM AI models outperform the vast majority of human experts in predicting personality item correlations, though aggregates are more mixed. nature.com/articles/s4427…

A call to academic psychologists (and those who trained in related fields) - it would be fantastic if you'd participate in our study on controversial and hotly debated topics in psychology! We'd also really appreciate it if you'd share this as we need more participants: ⬇️
