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).

Our translated (and tested) materials, along with our preregistration, data, and analyses are available at this link: osf.io/hk8rv/. (4/4)

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)
