What it operationalizes

This metric measures the construct(s) below from operational data. Through them, it connects to the meta-analytic relationship network — the bridge from what you measure operationally to what the science knows.

What we know

Synthesized Bayesian priors over relationships involving this metric’s construct(s) — the meta-analytic evidence, with 95% confidence intervals and between-study heterogeneity (I²). Follow a row for the full distribution, contributing studies, and code.

A realistic representation is critical for engineering as denying the agentic traits of the field would be an inaccurate representation of it—which would likely have negative consequences on retention (Earnest et al., 2011). supports
