psychological-safety
Overview
Based on "Leaders Eat Last" by Simon Sinek and Amy Edmondson's psychological safety research. Sinek's insight: humans are wired to withhold their best thinking in environments that feel unsafe. The Circle of Safety - the conditions under which people feel protected from external threats - is the leader's most fundamental responsibility. Without it, people use cognitive energy protecting themselves from internal threats (judgment, blame, embarrassment) rather than solving real problems. Edmondson's research found psychological safety is the single strongest predictor of team performance - more than talent, resources, or strategy.
The Four Stages of Psychological Safety
Edmondson and Sinek's work maps to a progression:
| Stage | Description | Signal |
|---|---|---|
| Inclusion | People feel accepted as members of the team | New members contribute within the first week |
| Learner | People feel safe asking questions and admitting they don't know | People say "I don't know" without hedging |
| Contributor | People feel safe doing their work and trying new approaches | People take initiative without asking permission |
| Challenger | People feel safe challenging the status quo and authority | People disagree with the leader openly |
Most teams that think they have psychological safety are at Inclusion or Learner. True high performance requires Challenger safety.
