Distribution
Uninformative prior. This prior is uninformative — too thin to dominate small-N posteriors. Treat as a placeholder until more evidence lands.
Historical evidence. This prior's contributing evidence is older than 15 years on average (centroid year 2000, ≈26 years old); treat the estimate as historical.
Intervals
- Confidence interval (95%) — uncertainty about the mean ρ
- [-0.39, -0.02]
- Credibility interval (95%) — distribution of the true effect across settings (the Bayesian prior)
- — needs ≥2 studies to estimate (k = 1)
- I² (heterogeneity) — share of total variance from between-study differences
- — needs ≥2 studies to estimate
k<2 — between-study heterogeneity not estimable; credibility interval / generalization not assessed
Evidence provenance
published ρ=-0.21 (k=1, replication: single); no primary-deployment evidence yet
| Source | ρ (r) | Scope |
|---|---|---|
| Published literature | -0.21 | k = 1 · N = 50 |
- replication: single
- aging literature (freshness=0.28)
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.
