Agreeableness
tendency to be cooperative, compassionate, trusting, and considerate of others
§1The Principia rendering
A copyright-clean measure of this construct, authored by Principia and free to use — the one we can show in full.
Predicted psychometrics. These 10 items carry a design grade of A (avg design score 98/100) from the item-design model — an estimate pending calibration, not a measured reliability. Real responses (via deployment) sharpen it toward measured, which is what the licensing model collects.

§3The math on what we know
Synthesized priors from the live registry: pooled r, studies (k), total N, top study grade, and heterogeneity. Rows flagged for heterogeneity or single-study evidence are directional, not settled — read them as a central tendency.
