Why People Don’t Believe You, Even When You’re Telling the Truth: Henna Pryor’s New Book, The Signal Gap

What a Signal Gap Actually Is

Henna defines the signal gap as the distance between the message you think you’re sending and the cluster of signals the other person actually receives. Your words are only one of those signals. Your tone, your timing, the context people already carry about you, and whether your behavior matches what you say all arrive at the same time, and the listener decides what to believe from the whole bundle rather than from the sentence you worked so hard on.

One of the examples in the book makes the point better than any definition could. An insurance executive used the industry phrase “acceptable loss ratio” in a short clip that went viral, because people outside the industry heard it as saying it was acceptable to him when your house burns down. He meant something technical and ordinary, and the audience received something else entirely. That space between intent and perception is exactly what the book teaches readers to see, and then to close.

Why Polish Stopped Working

For a long time the formula for winning a room was fairly simple: prepare thoroughly, polish the message, and deliver it with confidence. Henna’s argument is that this formula has quietly broken. Now that a warm, personalized note or a beautiful slide deck can be produced in seconds, people have learned to be suspicious of perfect words, and they have spent thousands of hours watching unscripted, candid people online, so they have a sharper sense than ever of what real sounds like. A message that is too smooth can now trigger the very doubt it was meant to remove.

What earns belief instead, she shows, is congruence, which means what you say, what you mean, what you believe and how you behave when nobody is managing the optics all line up. The book is grounded in behavioral science and original research, and it is written in the same warm, playful style her audiences know from the stage, so it reads less like a textbook and more like a conversation with someone who genuinely wants you to be understood.

What Readers Walk Away With

This is not another book about authenticity or about persuasion tactics. It is a practical guide to building influence through believability, and it gives readers a system for spotting where their credibility is leaking. Readers learn how to:

• Close the gap between the message they intend and the way it is interpreted
• Strengthen the signals people rely on to decide what is real
• Make their communication confirmable, not just compelling
• Build credibility quickly, consistently and in a way that lasts

If your work depends on people trusting you, whether that means your leadership, your ideas, your recommendations or your brand, this book was written with you in mind. That includes executives leading teams through change, sales professionals walking into skeptical rooms, and anyone who has ever wondered why their impact doesn’t match their intent.

Praise for The Signal Gap

The book arrives with endorsements from some of the most respected names in influence and leadership, including Daniel H. Pink, Dorie Clark, Tasha Eurich, Michael Bungay Stanier and Jordan Harbinger.

Bring The Signal Gap to Your Event

Henna brings the ideas from the book to life on stage in her keynote Mind the (Signal) Gap!, which shows audiences how to disarm the skepticism in the room first and then align the four layers of congruence (Communication, Belief, Context and Character) so their message holds up under any scrutiny. She also delivers The Changing Psychology of Influence, an interactive session on why people resist new ideas and how to move them forward anyway. Both are customized to the audience, and both pair naturally with copies of the book for attendees.

Henna has spoken twice for TEDx and at SXSW, writes as an Expert Columnist for Inc. Magazine, and has worked with organizations including Google, Workday, Johnson & Johnson and JPMorganChase. You can read more about her and her full set of programs on her Amplify Speakers profile.
