Subclaims¶

q3 i? After the first training session, the training group's initial intuitive accuracy rose far more than the control group's, with a significant Block x Group interaction. → Nina Franiatte 2024 q3 i? Final deliberate accuracy also increased sharply in the training group relative to control after the first session. → Nina Franiatte 2024 (2)

q3 · i? · causal · r2

Preregistered online experiment (120 adults, Prolific) comparing training and control groups on conflict trials across three reasoning tasks, using a composite accuracy measure; initial intuitive accuracy rose +42.0 points in the training group versus +7.9 in control, and the "Block x Group inte raction" was significant.

"Statistical composite analyses indicated that the Block x Group inte raction also significantly improved the model for the initial responses, χ2 (1) = 34.72, p < .001."

q3 · i? · causal · r2

Same Session 1 composite analysis: final deliberate accuracy increased +44.2 points in the training group (M = 76.9%) versus +8.9 points in control, with a significant Block x Group interaction on final responses.

"Statistical composite analyses revealed that the Block x Group interaction significantly improved the model for the final responses, χ2 (1) = 32.12, p < .001."

Discussion¶

Related Claims¶

• Debiasing training helps reasoners intuit the correct solution rather than correct an erroneous intuition through deliberation — related
• No-conflict control accuracy remained at ceiling after training, arguing against guessing and a reversed-heuristic account — related
• The training effect is somewhat weaker for tasks presented at the end of the one-hour battery, suggesting a fatigue effect — related
• A second training session two days later further increases reasoning accuracy beyond the first session, though less strongly — related
• Repeated training substantially reduces the proportion of biased responders and increases improved and correct responders at the individual level — related
• Training shows small trends toward better conflict detection on bat-and-ball and base-rate tasks but the opposite trend on the conjunction fallacy task — related
