Amy C. Edmondson is the Novartis Professor of Leadership and Management (formerly Morgan Distinguished Professor) at Harvard Business School, and the originator of the psychological safety construct — the shared belief that a team is safe for interpersonal risk-taking. Her 1999 paper in Administrative Science Quarterly established psychological safety as a measurable team-level variable with significant effects on team learning and performance. Her 2018 book The Fearless Organization translated the construct into practitioner language. Edmondson is not a flow researcher, but her construct is structurally essential to understanding the conditions for group-flow and team flow.
The psychological safety construct
Edmondson's 1999 ASQ study — "Psychological Safety and Learning Behavior in Work Teams" — examined 51 work teams at a manufacturing company and found that psychological safety predicted team learning behavior, which in turn predicted team performance. The construct was defined empirically: a shared belief held by team members that the team is safe for interpersonal risk-taking, such that members feel free to speak up, ask questions, admit errors, and propose untested ideas without fear of embarrassment, rejection, or punishment.
The study was notable for its methodology: Edmondson measured psychological safety as a team-level (not individual) variable, demonstrated that it was distinct from interpersonal trust at the individual level, and showed that it predicted learning — not comfort or happiness. This empirical precision gave the construct more traction in organizational research than earlier, vaguer formulations of team safety.
Connection to Sawyer's group flow conditions
sawyer's ten-conditions-for-group-flow include several that are structurally equivalent to Edmondson's psychological safety:
From Sawyer's perspective, psychological safety is a prerequisite condition — part of the social environment within which group flow conditions can be established and maintained. It is not itself a flow condition but a foundation without which several of the conditions cannot be achieved.
Connection to van den Hout's team flow prerequisites
van-den-hout's empirical research on team flow explicitly references Edmondson's psychological safety as mapping onto two of the team flow prerequisites identified in conceptualization-of-team-flow-2018:
van-den-hout's team-flow-monitor operationalizes these prerequisites at the team level, providing measurement that complements Edmondson's psychological safety scales. The convergence between Edmondson's independently derived organizational construct and van den Hout's team flow prerequisites — reached from different research traditions (organizational behavior vs. positive psychology/flow) — is a significant cross-methodological validation.
Significance for the flow lineage
Edmondson's contribution to the flow KB is indirect but structurally important. She produced the most rigorous empirical account of exactly the interpersonal conditions that sawyer described qualitatively from jazz and theater research, and that van-den-hout built into his team flow prerequisites. Her work provides an organizational behavior anchor for the claim that team flow requires a safe interpersonal environment — a claim that might otherwise rest solely on qualitative improvisation research. The psychological-safety construct is now widely used in software engineering organizations (amplified significantly by Google's Project Aristotle findings, which named psychological safety as the top predictor of team effectiveness) and represents the practical organizational science equivalent of the flow conditions framework.
