Everyone Says...: How We Mistake Confidence for Consensus
About this ebook
Drawing on the habits of statistical thinking—attention to uncertainty, variation, scale, and comparison—the book shows how confidence can be mistaken for agreement and how repetition can begin to sound like evidence. Rather than teaching statistics or presenting formal models, it offers readers a different way of listening: one that asks simple but powerful questions such as How many? Compared to what? Who is included?
Each chapter begins with a familiar phrase and places it in a real-world setting, including universities, youth sports, healthcare, organizations, media environments, elections, and everyday conversations. Through short, story-driven chapters, the book reveals why these statements feel persuasive, how they gain authority, and what can be lost when assumed consensus takes the place of careful thinking.
At its heart, Everyone Says... is an invitation to slow down, look more closely, and recognize the difference between confidence and consensus before decisions become settled too quickly.
