Psychological safety isn’t just about being nice

Psychological safety often gets mistaken for a nice, pleasant place to work.

Amy Edmondson, who coined the term, is clear that psychological safety isn’t about comfort, it’s about candour. People being able to say, ‘I got that wrong’, ask an obvious question, or challenge a plan without fearing it’ll be held against them later. 

Pleasant cultures often struggle here, because disagreement reads as unkindness and everyone’s too polite to call the problem out. They end up ‘agreeing to disagree’ and nothing ever gets resolved.

Google spent two years studying 180 of its own teams and found psychological safety mattered more than talent, seniority or team size in explaining which teams performed best. The high-safety teams weren’t just the nicest. They were the ones where people felt able to admit mistakes early, before it became too late to fix them.

The practical test for psychological safety is simple. When someone in your team raises a concern, does the conversation improve or does it get shorter? Repeated over weeks and months, that answer predicts performance more reliably than any other metric.

If your team is nice to work in but nobody’s told you your plan has a hole in it for three months, you don’t have psychological safety. You have politeness, and it’s costing you more than you realise.
