Distribution
Intervals
- Confidence interval (95%) — uncertainty about the mean ρ
- [-0.23, -0.11]
- Credibility interval (95%) — distribution of the true effect across settings (the Bayesian prior)
- [-0.25, -0.10]
- I² (heterogeneity) — share of total variance from between-study differences
- 84%
The true effect is ~constant across settings — it generalizes.
SD_ρ≈0 — true effect is ~constant across settings; generalizes (observed-score scale until artifact correction, PRN-058)
Evidence provenance
published ρ=-0.17 (k=2, high heterogeneity (I²=0.84)); no primary-deployment evidence yet
| Source | ρ (r) | Scope |
|---|---|---|
| Published literature | -0.17 | k = 2 · N = 12,096 |
- high heterogeneity (I²=0.84)
- 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.
