Trust That Drives Performance
High-performing organisations are not built on agreement. They are built on environments where people feel able to challenge assumptions, raise concerns and contribute differing perspectives without fear of judgement or negative consequences. When Google studied more than 180 of its own teams to find out what made the best ones effective, it expected the answer to lie in who was on them. Instead, Project Aristotle found that psychological safety was by far the most important factor.
Psychological safety creates the conditions for open and honest conversations. It enables people to ask difficult questions, acknowledge mistakes, offer alternative viewpoints and challenge decisions when necessary. Without it, concerns go unspoken, opportunities are missed and flawed decisions remain unchallenged until they become far harder to address.
Harvard professor Amy Edmondson found this almost by accident. Studying hospital teams, she expected the best teams to make fewer medication errors. The data showed the opposite: the strongest teams reported more errors. They weren't making more mistakes. They were more willing to talk about them, which is exactly what allows an organisation to learn.
Why it matters most during change
Its importance becomes even more pronounced during periods of change. Transformation requires organisations to learn, adapt and continuously improve. People are more likely to share ideas, identify emerging risks and embrace new ways of working when they believe their views will be heard and respected.
The commercial effect is measurable. Gallup estimates that if organisations doubled the share of employees who strongly agree their opinions count at work, from three in ten to six in ten, they could see a 27% reduction in turnover, a 40% reduction in safety incidents and a 12% increase in productivity. Psychological safety is therefore not simply a cultural consideration. It is an enabler of innovation, effective execution and sustainable performance.
Safety is not comfort
Psychological safety and accountability can, and should, coexist. Psychological safety should not be confused with comfort or a lack of accountability. High-performing organisations can maintain high standards and clear performance expectations while creating an environment where people feel safe to speak openly.
The distinction is not whether people are challenged, but whether they feel able to challenge others.
When trust and accountability exist alongside psychological safety, organisations are better equipped to navigate complexity, make informed decisions and create sustainable value.
