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 i? Raw desired-outcome quartiles (0.26, 0.55, 0.92) far exceed undesired-outcome quartiles (0.09, 0.17, 0.34), and the contrast persists after adjustment. → Mehmet Bicakci 2026

q3 · i? · quant-synthesis · r3
Valence-layer subgroup analysis of 5,163 desired vs. 793 undesired effect sizes; the article states "Desired outcomes showed substantially larger raw quartiles than undesired outcomes" with the printed values above. Valence produced the strongest separation of any layer.
"Desired outcomes showed substantially larger raw quartiles than undesired outcomes (0.26, 0.55, and 0.92 vs. 0.09, 0.17, and 0.34), and this contrast persisted after adjustment"
Discussion¶
Related Claims¶
- Benchmarks are sensitive to precision and publication bias, but subgroup ordering remains stable and one-per-primary-study quartiles are broadly similar to raw values — related
- STEM field benchmarks differ markedly: science shows the largest quartiles and mathematics the smallest — related
- Publication-bias adjustment via limit meta-analysis lowers the overall STEM benchmarks to 0.14, 0.32, and 0.59 — related
