Why Perpetual recommends it
L. David Marquet’s Leadership Is Language, written by the former submarine commander behind Turn the Ship Around!, makes the case that the specific words leaders use, often without noticing, either invite genuine thinking from a team or quietly shut it down. Marquet argues that command-style phrases like I intend to train people to wait for instructions, even when the leader’s real intention is to encourage initiative.
The book is built around concrete, swappable language patterns. Instead of asking closed questions that invite a yes or no, Marquet pushes leaders toward open, curious phrasing that surfaces real information; instead of language that implies certainty, he encourages leaders to talk in probabilities, giving a team permission to disagree with a plan before it’s too late to change course.
Marquet is particularly compelling on how much operational risk gets baked into a team simply because junior staff felt it wasn’t their place to question a senior person’s plan out loud, a dynamic he traces directly back to habitual leadership language rather than individual courage or cowardice.
We find this book genuinely practical for leadership teams because it turns something as abstract as psychological safety into specific, observable phrases leaders can start swapping out immediately.
- The specific words leaders use shape how much genuine thinking a team offers
- Closed, certainty-loaded language quietly discourages disagreement before it happens
- Talking in probabilities instead of certainties invites others to challenge a plan safely
- Small language habits, not just formal culture initiatives, shape how safe a team feels speaking up
A practical exercise is recording or reviewing your language in the next few team meetings, specifically counting how many closed, certainty-loaded statements you make versus open, probability-framed questions.
We give this book four and a half out of five stars.
