Subclaims¶

q3 i? After Session 1, 47.9% of training-group participants were classified as improved responders versus 11.8% in control, while biased responders were 23.7% versus 66.1%. → Nina Franiatte 2024 q3 i? After Session 2, only 12.1% of the training group remained biased responders, and 70.9% were correct responders. → Nina Franiatte 2024 (2)

q3 · i? · causal · r2

Individual-level direction-of-change classification (Raoelison & De Neys, 2019; categories from Boissin et al., 2021, 2022) of all 120 Session 1 reasoners into biased, correct, improved, and other categories.

"They amounted to 11.8% of reasoners in the control group and 47.9% in the training group."

q3 · i? · causal · r2

Session 2 individual-level classification: 70.9% of the training group were correct responders giving majority "11" patterns (vs 27.4% in control), improved reasoners rose 15.1% (vs 4.8% spontaneous improvement in control), and only 12.1% remained biased.

"Finally, in the training group there only remained 12.1% biased responders (vs 66.1% in the control group"

Discussion¶

Learner Variables¶

• Proportional Reasoning — outcome: instruction changes it

Related Claims¶

• A second training session two days later further increases reasoning accuracy beyond the first session, though less strongly — related
• A single debiasing training session significantly increases both intuitive and deliberate accuracy on classic reasoning tasks compared to control — related
