Data, not opinions: The psychometrics of team
summary
Argues that team performance is measurable by a 3‑dimensional model of psychological safety, cognitive diversity, and empathy and demonstrates a mixed-methods pipeline: a Team Dynamics Inventory survey, NEO‑PI‑R personality profiles, point‑biserial correlations, inter‑class correlation, scree plots and factor analysis to find clusters. Case studies show interventions shifting teams from non‑generative to generative behavior, two clear clusters per company, and a striking correlation of r=0.816 p=0.004 between agreeableness and encouraging behavior, with one outlier identified for re‑teaming.
