The data are consistent in this simple but interesting finding: psychological safety seems to “live” at the level of the group. In other words, in the organization where you work, it’s likely that different groups have different interpersonal experiences; in some, it may be easy to speak up and bring your full self to work. In others, speaking up might be experienced as a last resort - as it did in some of the patient-care teams I studied. That’s because psychological safety is very much shaped by local leaders.

One of the most important things to keep in mind, wherever you work, is that the failure of an employee to speak up in a crucial moment cannot be seen. This is true whether that employee is on the front lines of customer service or sitting next to you in the executive board room. And because not offering an idea is an invisible act, it's hard to engage in real-time course correction. This means that psychologically safe workplaces have a powerful advantage in competitive industries.

In many organizations, like those discussed in this chapter, countless small problems routinely occur, presenting early warning signs that the company's strategy may be falling short and needs to be revisited. Yet these signals are often squandered. Preventing avoidable failure thus starts with encouraging people throughout a company to push back, share data, and actively report on what is really happening in the lab or in the market so as to create a continuous loop of learning and agile execution.

Many who analyze events leading up to tragic accidents such as this one-which could have been avoided had the junior officer spoken up-cannot help pointing out that people should demonstrate a bit more backbone. Courage. It is impossible to disagree with this assertion. Nonetheless, agreeing doesn't make it effective. Exhorting people to speak up because it's the right thing to do relies on an ethical argument but is not a strategy for ensuring good outcomes. Insisting on acts of courage puts the onus on individuals without creating the conditions where the expectation is likely to be met.

Owning our errors becomes easier when we accept human fallibility as a fact and put that acceptance to use in learning and improving. In the most successful teams in my research, people, especially team leaders, talk about the ever-present chance that things will go wrong. They are honest and good-humored about mistakes, which nurtures the psychological safety you need for people to speak up quickly about them. This is a best practice—in families, too, not just work teams—if you want to reduce basic failures.
