Distribution
Intervals
- Confidence interval (95%) — uncertainty about the mean ρ
- [0.20, 0.52]
- Credibility interval (95%) — distribution of the true effect across settings (the Bayesian prior)
- [0.04, 0.62]
- I² (heterogeneity) — share of total variance from between-study differences
- 100%
The true effect varies across settings — moderators likely matter.
SD_ρ>0 — true effect varies across settings; likely moderated (observed-score scale until artifact correction, PRN-058)
Evidence provenance
published ρ=0.37 (k=4, high heterogeneity (I²=1.00)); no primary-deployment evidence yet
| Source | ρ (r) | Scope |
|---|---|---|
| Published literature | 0.37 | k = 4 · N = 75,953 |
- high heterogeneity (I²=1.00)
- replication: meta-analytic
No primary-deployment evidence yet — this prior rests on published literature alone. As anonymized, aggregated effect sizes from real deployments are contributed, they appear here as a distinct, publication-bias-free source, fused with the literature into a posterior estimate.
