New paper with the awesome S. Prasad Chandrashekar in the lead! We tested if “packing” information influences perceived consensus about climate change. We didn’t find that but found a kind of false consensus effect 🤔 read more about it in Collabra: Psychology !

OpenAI has launched Operator, an agent that can perform tasks in your browser. I asked it to complete a Qualtrics survey I created. The results are very promising for Operator but *very* concerning for survey researchers

Fresh out in Psychological Review! Why do so many societies explain events through fate, spirits, or divine will—but rarely invoke “chance”? My new article examines the cross-cultural absence of chance-based explanations and what it reveals about human cognition.

My most rejected paper — and my final PhD paper, and first solo-author article — is out in Social Psychological Bulletin! Preprint (+ data, code, materials): osf.io/bp4au_v1/ 🧵 A thread 👇🏻

Is sunk cost bias one phenomenon or many? Consider: eating is eating, but the psychology differs whether you're driven by hunger or boredom. So, sticking with failing investments might involve distinct psych. mechanisms masquerading as a single bias. Link to paper ➡️last post)

Michał Białek Interesting findings! We also found very weak/near zero/sometimes negative associations among problems measuring the representativeness heuristic: mgto.org/wp-content/upl… Research by Lukas Röseler has found the same pattern among anchoring problems: ejop.psychopen.eu/index.php/ejop…

Nice summary of my first solo author and most rejected paper now out in Social Psychological Bulletin! No self-other differences in risky decision making among experts, but all were susceptible to gain and loss framing.

Upcoming in JPSP Psychologists study morality by having people respond to hypothetical "trolley dilemmas". We confronted people with a real-life version. Not with runaway trolleys, but with people hooked up to electroshock machines: "Do you want to save two people from pain by
