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.
q3 i1 At pre-task the feedback group was significantly less underconfident than the no-feedback group, but groups did not differ significantly in post-task metacognitive bias. → Ceri Ngai and Sam J. Gilbert 2026

q3 · i1 · causal · r2
Pre-registered Experiment 1 (N = 164) comparing signed metacognitive bias between groups at pre- and post-task. The pre-task comparison showed the feedback group "significantly less biased than the no-feedback group" (d = .29); the post-task comparison was not significant (d = .022).
"At pre-task, the feedback group was significantly less biased than the no-feedback group (t(137.4) = 1.9, p = .03, d = .29; note that this p value is for a one-tailed test, in accordance with our pre-registered hypothesis that feedback should reduce metacognitive bias)."
Discussion¶
Learner Variables¶
- Self-Regulation — outcome: instruction changes it
Related Claims¶
- In Experiment 2, signed metacognitive bias scores showed no significant group effect or linear trend, failing to replicate the Experiment 1 signed-bias finding — related
- In Experiment 1, the feedback group showed significantly lower absolute (unsigned) metacognitive bias than the no-feedback group at both pre-task and post-task — related
- Bias scores did not improve over the school year, but school year level mattered: year 1 students became less overconfident while year 3 students improved their underconfidence — related
- Providing a rubric reduces bias in self-assessment, moving judgments closer to expert ratings — related
