In hesitating and then choosing not to speak up, Christina was making a quick, not entirely conscious, risk calculation – the kind of micro-assessment most of us make numerous times a day.

When I studied top management teams with action scientist Diana Smith, we analyzed detailed transcripts of their conversations to show how a psychologically safe climate for candid discussion of strategic disagreement can be created, even in high-level teams confronting strategic challenges, and how this can enable productive decision-making.

...the assembled group could have readily resolved the ambiguity with some simple analyses and experiments had they listened intensely and respectfully. In short, for voice to be effective requires a culture of listening.

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.

I don't mean to imply that working in a fearless organization takes more effort or a tremendously difficult undertaking. It doesn't. But initially, when we've been entrenched in fear and its attendant mental frameworks, it's not always obvious.
