Argument evaluation, Fast and Slow: Deliberation boosts justification strength discrimination in reasoning problems

3/4 📊 Fast, intuitive judgments partly distinguished strong from weak justifications, mostly when arguments backed participants' answers. Deliberation sharpened discrimination, even for arguments that contradicted participants' answers.

2/4 ⚙️ Across 3 studies, we had people solve reasoning problems and then rate justifications supporting different answers to these problems. Evaluations were made either under time pressure and cognitive load, or with time to think and without constraints.

1/4 🧵 New paper out (open access!) with @wimdeneys.bsky.social Can people tell a strong argument from a weak one on the fly, or only once they stop to think? We find that people already have some intuitive sensitivity to argument strength, but deliberation helps a lot.

I'll be giving a (virtual) flash talk at #CogSci2026 today (15:30 Rio time, 20:30 Paris time) on how argument evaluations from LLMs compare to human (intuitive and more deliberate) ones! 🤖💬 @cogscisociety.bsky.social joint work w/ @wimdeneys.bsky.social at @lapsyde.bsky.social @upcite.bsky.social

I'll be at #APS2026BCN presenting "The Price of Thought: Cost-Benefit Tradeoffs Shape Reasoning Engagement." W/ Talia Sander & @wimdeneys.bsky.social we put a price tag on thinking time to see how people value deliberation. Turns out: mostly, they won't pay -but that might be rational. Come say hi!👋

People and LLMs evaluate deliberative reasoning more favorably than intuitive thinking—even when both yield accurate results. This preference appears to be intuitive itself and has implications for how we assess others’ and AI advise. @wimdeneys.bsky.social www.nature.com/articles/s44...

Importantly, we show here that this doesn't just mean rationalizing faulty intuitions. Deliberation also enables to (better) justify sound ones. Beyond correction, deliberation thus plays a key role in justification, supporting metacognitive monitoring, explanation, & epistemic accountability. (4/4)

So deliberate reasoning (aka Type 2 reasoning/System 2) not only serves to correct erroneous/biased intuitions. It supports cognitive transparency: the ability to access, understand, and articulate the basis of one’s reasoning. In other words, it makes our thinking explicit. (3/4)

We found that intuitive correct responses were often poorly justified. However, participants gave much clearer and normatively appropriate explanations after deliberative correct responses (even when their answer didn't change). (2/4)

We asked people to solve classic reasoning problems (bat-and-ball, base-rate, risky-choice) twice: • Once under time pressure (intuitive response) • Then again with unlimited time (deliberate response) After each response, they were asked to provide a justification for their answer. (1/4)

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!

New preprint: “Folk Thinking, Fast and Slow: Intuitive Preference for Deliberation in Humans and Machines” Pop culture often praises intuition (“Blink”, Steve Jobs). But do we really trust it? Across 13 studies, we find a strong intuitive preference for deliberation. tinyurl.com/8r54dmyn (1/6)
