How leaders create cultures where people speak up

Executive overview

Most organisations say they want people to speak up. Few build the environment that makes it happen. NASA solved this through deliberate culture-setting: explicit norms, protected reporting, and modelled behaviour from leaders.

The gap between invitation and action closes only when leaders respond well every single time someone speaks up — whether the input was right or wrong.

The leader's response in the moment defines whether people speak up next time.

The trigger for speaking up

• A visceral discomfort — a sinking feeling, something that "doesn't seem right" — is a reliable signal.
• Speak up even when uncertain. Being wrong is recoverable; staying silent may not be.
• Rookies and outsiders notice things experienced people miss — their antenna are up, their defaults aren't set.
• Accepted inefficiencies are a specific trigger: if something is done the same way repeatedly but with ongoing difficulty, it's worth questioning.

The power of "thank you"

• When someone calls an all-stop or raises a concern — even incorrectly — saying "thank you" signals their attention was valued.
• A single dismissive response conditions the team to stay quiet next time.
• Leaders are watched closely; their in-the-moment reaction sets the cultural norm for everyone else.
• Even a new, inexperienced astronaut sets a tone that ground crews and instructors follow.

Speaking up when you are the one who made the mistake

• NASA required anyone involved in a close call to brief the entire astronaut office at the Monday meeting.
• The logic: if it can happen to one person, it can happen to anyone; sharing prevents recurrence.
• No penalty for coming forward; major penalty for concealment — one pilot who hid aircraft damage never flew in space again.
• Trust is built when leaders model confession, not just competence.

Rookies as a strategic asset

• Fresh eyes haven't normalised the workarounds. They're more likely to ask "why do we do it this way?"
• New team members identified two separate tool improvements for Hubble servicing missions — both were adopted and used on orbit.
• The right response to a new person's idea: listen, prototype, test. Even if 10 ideas are bad, one may be mission-critical.
• Don't judge on first impression — if someone was selected, assume they were selected for a reason.
