Their work shows that psychological safety makes it easier for people to speak up about problems and to alter and improve work processes rather than engaging in the counterproductive workarounds.

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.

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.

A culture of silence is thus not only one that inhibits speaking up but one in which people fail to listen thoughtfully to those who do speak up – especially when they are bringing unpleasant news.

The operative word here is “listening.” In the Chapters 5 and 6, you will read about eight flourishing organizations where leaders have created the conditions to make listening and speaking up the norm, not the exception. In these fearless workplaces, it's far less likely that employees will refrain from sharing valuable information, insights, or questions and far more likely that leaders will listen to rather than dismiss bad news or early warnings.
