Psychological Safety
Edmondson's foundational construct — the shared belief that a team is safe for interpersonal risk-taking — and the single strongest predictor of whether AI adoption produces learning or concealment.
Psychological safety is the shared belief, held by members of a team, that the team is a safe environment for interpersonal risk-taking. It is not about being nice, lowering standards, or eliminating conflict. It is the specific condition under which people will admit ignorance, ask naive questions, challenge confident claims, and report mistakes without fear of humiliation or punishment. Edmondson first identified the construct through a 1996 study of hospital nursing teams that produced a counterintuitive finding: better-performing units reported more errors, not fewer, because their environments made it safe to surface them. Thirty years of subsequent research — culminating in Google's Project Aristotle — has confirmed it as the most reliable predictor of high-performing teams, and its importance scales with the uncertainty, complexity, and knowledge-intensity of the work.

The construct's diagnostic power lies in what it explains that other organizational variables cannot. Teams with equal technical expertise, equal resources, and equally experienced leadership produce radically different outcomes,
