Weakly informative prior. This prior is weakly informative. It will nudge your posterior but won't overwhelm it; expect data to do most of the work in modest samples.

Intervals

Confidence interval (95%) — uncertainty about the mean ρ
[0.19, 0.54]
Credibility interval (95%) — distribution of the true effect across settings (the Bayesian prior)
[0.02, 0.65]
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=0.38 (k=4, high heterogeneity (I²=1.00)); no primary-deployment evidence yet

Sourceρ (r)Scope
Published literature0.38k = 4 · N = 59,513

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.
