1/15 What do we actually do when we deliberate, and how does it change over time? New preprint with @wimdeneys.bsky.social : "Rhythm of Thought: Tracing the Dynamics of Deliberation in Reasoning". 🔗 doi.org/10.31234/osf... (yes, I like flashy titles 💅) A 🧵👇

Abstract

When an intuitive answer is uncertain, people are thought to engage in further reasoning. But what people actually do during this additional thinking, how it unfolds over time, and why it sometimes leads to better answers remain unclear. We scored think-aloud protocols with large language models to track, moment by moment, four possible functions of deliberation (generating candidate responses, justifying them, controlling intuitive responses, and regulating cognitive effort), together with expressed confidence. Deliberation showed a clear temporal organization: generation dominated early, whereas justification, control, and regulation became increasingly prominent as reasoning progressed. Correct responses involved more justification, control, and regulation than biased responses, and these evolving dynamics predicted accuracy for out-of-sample participants and items. Confidence and deliberation also showed reciprocal lagged associations: lower confidence predicted further generation, justification, and control, whereas regulation predicted subsequent increases in confidence. Deliberation, then, appears to involve not a single act of "thinking harder," but an evolving interplay of reasoning processes whose organization is linked to whether reasoning succeeds.

Keywords: deliberation; reasoning dynamics; verbal protocols; large language models; metacognition; dual-process theories

Happy to share a new preprint with @tomcostello.bsky.social, @dgrand.bsky.social and @gordpennycook.bsky.social 🧵 "What beliefs are most debunkable?" osf.io/preprints/ps... We investigate the characteristics of the beliefs that are (or are not) influenced by counterevidence in 3,341 AI dialogues.

Happy to share that my first paper is out in Thinking & Reasoning! 📄📢 With Aikaterini Voudouri, @boissinesther.bsky.social & @wimdeneys.bsky.social we show that deliberate reasoning helps not just to correct but also to justify intuitive judgments. 🔗Full paper: shorturl.at/JTeTi Quick thread below!

Conspiracies emerge in the wake of high-profile events, but you can’t debunk them with evidence because little yet exists. Does this mean LLMs can’t debunk conspiracies during ongoing events? No! We show they can in a new working paper. PDF: osf.io/preprints/ps...

Recent research shows that AI can durably reduce belief in conspiracies. But does this work b/c the AI is good at producing evidence, or b/c ppl really trust AI? In a new working paper, we show that the effect persists even if the person thinks they're talking to a human: osf.io/preprints/ps... 🧵

Who benefits (or doesn't) from debiasing training? We find that intuitive-analytic thinking dispositions, and not cognitive ability, predict training effectiveness. New paper from: boissinesther.bsky.social & gordonpennycook.bsky.social www.sciencedirect.com/science/arti...
