- 1/13 New paper with @wimdeneys.bsky.social accepted at @cognitionjournal.bsky.social 🥳 Is creativity intuitive? 👩🎨 A 🧵👇
- 2/13 Convergent thinking, the ability to find a single correct solution to a problem, is often thought to rely on deliberate, controlled processes. We examined (1) how much deliberation contributes to creative problem solving and (2) the mechanisms underlying sound intuitive processes.
- 3/13 We used the widely used Compound Remote Associates (CRA) task, in which participants must identify a word that links three cue words (e.g., river, note, account → bank).

- 1/10 🚨 New preprint: Using Large Language Models to Estimate Belief Strength in Reasoning 🚨 When asked: "There are 995 politicians and 5 nurses. Person 'L' is kind. Is Person 'L' more likely to be a politician or a nurse?", most people will answer "nurse", neglecting the base-rate info. A 🧵👇
- 2/10 Cognitive biases often involve a mental conflict between intuitive beliefs (“nurses are kind”) and logical or probabilistic information (995 vs 5). 🤯 But how strong is the pull of that belief?
- 3/10 We argue that measuring “belief strength” is a major bottleneck in reasoning research, which mostly relies on conflict vs. no-conflict items. It requires costly human ratings and is rarely done parametrically, limiting the development of theoretical & computational models of biased reasoning.

- Reposted by Jérémie BeuclerCan large language models stand in for human participants? Many social scientists seem to think so, and are already using "silicon samples" in research. One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want. THREAD 🧵

- Curious about the mechanisms behind biased reasoning and metacognition? 🤔 📍 Come see our poster at #CCN2025, Aug 12, 1:30–4:30pm We show how a biased drift-diffusion model can explain choice, RT and confidence in a base-rate neglect task, revealing why more deliberation doesn’t always fix bias.

- 1/8 New (and first) paper accepted at JEP:LMC 🎉 Ever fallen for this type of questions: "How many animals of each kind did Moses take on the Ark?" Most say "Two," forgetting it was Noah, and not Moses, who took the animals on the Ark. But what’s really going on here? 🧵
- 2/8 These semantic illusions are often used to test for deliberate "System 2" thinking (e.g., in the verbal Cognitive Reflection Test). The classic theory? We intuitively fall for the illusion & need slow, effortful deliberation to correct the mistake. But is it really that simple?
- 3/8 To test this, we ran 4 experiments with over 500 participants! We used a two-response paradigm: first, a quick intuitive answer under time pressure & cognitive load. Then, a final, deliberated response with no constraints. Here are the main results:
