Intervals

Confidence interval (95%) — uncertainty about the mean ρ
[0.33, 0.41]
Credibility interval (95%) — distribution of the true effect across settings (the Bayesian prior)
[0.32, 0.42]
I² (heterogeneity) — share of total variance from between-study differences
87% — considerable heterogeneity; moderators likely dominate

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=0.37 (k=2, high heterogeneity (I²=0.87)); no primary-deployment evidence yet

Sourceρ (r)Scope
Published literature0.37k = 2 · N = 18,338

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.
