Subclaims¶

q3 i? Coherence rates were higher when advice was revealed (66%) than concealed (48%), with posterior median difference 0.29 (HDI 89% = 0.25 to 0.33); no standardized effect size was printed. → Maayan Pereg 2024

q3 · i? · causal · r2

Hierarchical Bayesian logistic regression on the two-session student-teacher bandit task (153 participants) comparing coherence rates in revealed vs concealed advice conditions, showing a "causal influence of advice on compliance" with posterior median difference 0.29 (HDI 89% = 0.25 to 0.33); no standardized effect size was printed.

"participants were more likely to choose the card advised by the teacher when the teacher's advice was revealed (66% coherence rate) compared to when the advice was concealed (48% coherence rate; posterior median estimation for the difference in the population was 0.29"

Discussion¶

Related Claims¶

• The tendency to follow advice shows good test-retest reliability across two sessions (~0.73), behaving as a stable trait-like bias — related
• Simulated data show a double dissociation: early-trial reveal effects arise only from non-informed advice-taking, while outcome-dependent coherence repetition arises only from informed advice-taking — related
• Advice framed as social information holds greater causal influence than an identical non-social cue (a lottery wheel) — related
• Estimated parameters indicate simultaneous reliance on individual learning (ω ≈ 0.70) and a fixed non-informed bias to follow advice (φ ≈ 0.2) — related
