The Safest Teams Take the Biggest Risks

"Psychological safety is not about being nice. It's about giving candid feedback, openly admitting mistakes, and learning from each other."

— Amy Edmondson

Context

Edmondson developed the concept of psychological safety through hospital research in the late 1990s and has spent decades testing it across industries from aviation to software to healthcare. Her foundational finding still surprises people: when she measured error rates across nursing teams, the best teams reported the most mistakes. Her first instinct was that something was wrong with her data. What she eventually understood was that the better teams had built an environment where nurses felt safe enough to speak up when something went wrong — and in doing so, they learned faster, caught problems earlier, and ultimately performed better. The lesson she draws is precise: psychological safety is not comfort or harmony or the absence of conflict. It is the specific condition under which honest work becomes possible. Without it, people spend energy managing impressions rather than solving problems.

Reflection Question

In the teams or relationships where you spend most of your time, how safe do people actually feel to say what they think is wrong? And what does the way you respond when someone admits a mistake or raises a concern tell them about whether it is safe to do it again?

Application Tip

In your next team meeting or significant one-on-one, try Edmondson's simplest intervention: be the first to admit something you got wrong or don't know. Not performatively — something real. Then notice what happens in the room. Research consistently shows that when the person with the most authority models vulnerability and candor, others follow. Safety is not a policy you announce. It is a climate you create, one honest moment at a time, and it starts with whoever speaks first.
