Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? The winning model's ω parameter (~0.70) reflects reliance on both individual learning and informed advice-tracking, and φ (~0.2) reflects a fixed tendency to follow advice unrelated to teacher accuracy. → Maayan Pereg 2024

q2 · i? · causal · r2
Posterior estimates of the winning model's free parameters (Fig. 3) indicate participants weighed card values and advice value (ω ~0.70) and carried a fixed advice-following bias (φ ~0.2) that increased following "even when it went against one's individual experience".
"The ω parameter was estimated to be ~0.70 (Fig. 3c), indicating a reliance on individual learning, but also on informed advice-taking, which tracked the accuracy of the teacher"
Discussion¶
Related Claims¶
- A computational model combining informed and non-informed advice-taking with individual learning (Model 5) best predicts participants' choices — related
- Revealing a teacher's advice causally increases participants' tendency to choose the advised card in a reinforcement learning task — related
- A high bias to follow advice may be bounded by task uncertainty: learning demands were high in this design, and a weaker bias might emerge under lower demands — related
