Circle of Safety

In Leaders Eat Last, Sinek divides the dangers an organisation faces into two kinds. External ones, such as competitors, market shifts and new technology, cannot be controlled. Internal ones, such as blame, office politics, public humiliation and the fear of sudden layoffs, are made inside the organisation and can be removed. Inside a strong Circle of Safety, people stop spending energy on self-protection: they share information, report mistakes early and help each other without keeping score. Where the circle is narrow or has gaps, the same people cover themselves, which looks like a culture problem but is a reasonable response to an unsafe place. The leader sets the edge of the circle, and the people left outside it notice quickly. Sinek's argument is moral as well as practical, and it rests mostly on military and company examples rather than on controlled studies. It sits close to Amy Edmondson's research on psychological safety, which found that better-led hospital teams recorded more errors because they felt safe enough to speak about them. A practical test is to ask what people on a team protect themselves from inside it, and to remove one item on that list.
