When Google studied its most successful teams, they discovered the secret isn’t in the ‘who’–it’s in the ‘how.’

When Google’s People Operations department (their version of human resources) set out to study what made their most high-performing teams tick, they were surprised by the results. It turns out it isn’t a magic combination of skill sets, individual traits, educational backgrounds, or even cultural backgrounds that makes a team successful. It is something more.

Over the span of two years, Google studied the attributes of more than 180 of the company’s teams. They interviewed more than 200 workers around the globe. What they found was that a team’s success didn’t depend on who was on it–it depended on how the workers felt as members of the team. How the team members interacted, structured their work, and viewed their contributions had the greatest impact on a team’s success.

There were many dynamics that contributed to employees feeling this way on their high-performing teams. But Google discovered one to be the most crucial: the dynamic of “psychological safety.”

What is psychological safety?

Google defines psychological safety as a state of being. It’s the feeling team members have when they believe they can take risks without feeling insecure or embarrassed. They feel safe to be vulnerable in front of one another.

Why is this important? When workers feel they are safe to take risks, they are not afraid to fail. They are open to trying something new and to challenge the status quo. The result is they become more creative and innovative. They perform at a higher level because they strive for the best as a team–instead of striving to protect themselves as individuals.

How do you create psychological safety?

Psychological safety isn’t the responsibility of leaders alone–it takes an entire team to co-create this environment. Here are three steps to start the shift.

1. Establish conversational turn-taking.

When a team functions in harmony, each member speaks an equal amount of time. One or two people do not dominate the discussion. Everyone feels like they got the opportunity to contribute, and no one holds back. This type of balance doesn’t happen automatically–it takes intention and practice. Often, it’s as simple as being aware of who isn’t speaking, and welcoming them into the conversation. But there are other approaches, too. I work with a leader who has discovered an ingenious way to achieve this balance. If he, or anyone else on the team, notices someone hasn’t contributed, they hand that person a small rock. If someone has the rock, it’s their turn to speak. The rock is passed quietly, discreetly, and is a way of saying, “I’d love to hear what you think.”

2. Self-check negative behavior.

If a team has a history of destructive behaviors such as sarcastic comments, demeaning remarks, or other micro-inequities, it’s a leader’s job to call out those behaviors and discourage them. Then, it’s up to the entire team to constantly monitor one another–and themselves–to make sure these behaviors don’t pop up. If they do, they can erode relationships and impede progress toward psychological safety. A team functions best when individual ego is out of the room and there’s mutual respect among each member.

3. Have high social sensitivity.

Much of what we communicate is non-verbal. We convey as much information through our tone of voice, facial expressions, and body language as we do in our words. When a team has a culture of mutual respect, the people on it have a heightened awareness of what their colleagues are communicating. They are sensitive to how other team members feel and react. This is a key component of psychological safety.

Google’s research turned up an additional fascinating fact: According to a report by Julia Rozovsky from Google’s People Operations, the workers on teams with psychological safety also perform more strongly as individuals. They are less likely to leave the company and more likely to embrace diverse ideas, they bring in more revenue, and they are more likely to be rated as effective by management.

If you want similar results for a team you lead–or a team you are in–start by embracing a culture of respect, social sensitivity, and the idea that it’s everyone’s responsibility to co-create a psychologically safe environment.
