The Three Skills of Successful Groups

High performance is often viewed as the result of individual intelligence and talent. However, when business students and kindergartners are challenged to build a spaghetti tower, the children consistently win. While the adults waste time managing their status and navigating social hierarchies, the children dive straight into the work. They don't worry about who is in charge; they simply experiment and adapt as a single unit.

This reveals that group culture is not a fixed trait or a stroke of luck, but a set of specific skills. It is not something a group is, but something a group does. Success depends on the quality of interactions rather than the sum of individual resumes. When people feel safe and connected, they stop competing with one another and start solving problems together.

To build this kind of chemistry, groups must master three essential skills: building safety, sharing vulnerability, and establishing purpose. These behaviors signal to our social brains that we belong and can take risks. By shifting focus from personal status to shared goals, any group can transform into a high-performing team that is far greater than the sum of its parts.
