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? Mind wandering is consistently negatively associated with test performance across tasks, subjects, and age groups, explaining about 7% of outcome variation. → Bühler 2025

q2 · i? · review · r3

The review reports, citing Wong et al. (2022), that task-unrelated thoughts show a consistent negative association with test performance, "accounting for approximately 7% of the variation in learning outcomes." The 7% figure is a variance proportion, not a standardized effect size.

"Task-unrelated thoughts are consistently associated with lower test performance across different tasks, subjects, and age groups, accounting for approximately 7% of the variation in learning outcomes"
