The room that has stopped being willing to hear the case against itself looks exactly like a room that has done

When Everyone Agrees, You're Wrong is not a corporate training manual, a guide to better brainstorming, or a

call for contrarian posturing. It is a forensic analysis of the eighteen-inch gap between what people know and

what they say-the documented mechanics of how capable teams ratify decisions they privately believe are

wrong.

Through case studies from war rooms, cockpits, and boardrooms, you will encounter the specific machinery of

incorrect-why intelligent people do it, and why it compounds across hierarchies.

- Warnings Nobody Carries Upstairs: How organizational distance turns critical information into

structural mechanics of how...
