"Defining deliberation for dual-process models of reasoning" is now published. Free online access to the published Nat Rev Psy version: rdcu.be/erM5T

TL;DR
✅ Animated videos help people intuitively reason better
🧠 Supports the “trained intuitor” view (not just System 2 correction)
📚 Aligns with broader findings from multimedia learning research (4/4)

Open access to our debiasing videos: osf.io/5fuh9/ (3/4)

We compared 3 groups:
📹 Video training
📄 Text training
🚫 Control (no training)

We found that debiasing videos boost performance on classic reasoning tasks, even at the intuitive stage (under time pressure & cognitive load). Effects lasted for over 2 months. (2/4)

In 6 preregistered studies, we examined the effect of video-based training: Does it improve only deliberate reasoning or can it also boost intuitive performance, like text-based debiasing training? (1/4).

📹 We show that video debiasing training can boost reasoning accuracy - not just deliberation, but intuition too!

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.

Key results: After a short (5 min) intervention, the majority of biased reasoners started to respond correctly, as early as the intuitive stage. These findings show that the intuitive debiasing training effect extends to French speakers. (3/4)

Participants solved a set of heuristic and biases tasks with the two-response paradigm. On every trial, they provided both an initial "fast" response under time pressure and cognitive load and a subsequent final "slow" response. (2/4)

⬇️ In this paper, we explored whether we could replicate previous debiasing findings among native French speakers. (1/4)

Why can people solve reflection tests without reflecting?

Prior exposure.
