Leadership believability shapes whether people trust your message, follow your guidance, and act on your ideas. While leaders often assume credibility comes from expertise, audiences make decisions about trust using a combination of objective factors—such as reputation and track record—and subjective impressions formed in seconds. As AI makes communication faster and more polished, understanding what drives believability has become essential for leaders who want to build trust and influence.
I just don’t believe you.
That’s what I thought, sitting in the audience at an AI conference at MIT earlier this year. The speaker represented a large Fortune 50 company; she could have been one of my clients.
While she spoke, I felt something was off. Why? Her language was too polished, too corporate. She had generic and overused expressions, such as, “AI won’t replace you, but someone using AI will.” It sounded like she was reading from a series of talking points instead of sharing her own authentic, original thought. I kept asking myself if she actually believed what she was saying.
Later, at lunch, I mentioned to the man sitting next to me that I study believability. He leaned in and whispered: “Oh yeah? What did you think of this morning’s speaker?”
Turns out, he didn’t believe her either. But his reason had nothing to do with her language. He responded, “She flipped her hair back too much. It looked like she was trying too hard.”
Two people had the same conclusion, but for completely different reasons. That paradox is at the heart of believability.
Leadership Believability Is More Subjective Than We Think
This lunch exchange illustrates what I’ve been studying and observing over the past few years. The more I study believability, the more nuanced it becomes – and I’m starting to see patterns emerge.
What makes people believe you when you speak?
What they know about you: Some components of believability are objective: your credentials, your reputation, and your actions. When what you say matches what you do, people are more likely to believe you.
What they feel about you: But other components of believability include more subjective, biased criteria: Do you look like me? Do you remind me of someone I trust—or someone I distrust?
From the moment we meet someone, we perform a threat assessment in milliseconds. From the way they dress to the way they carry themselves, we evaluate someone’s credibility and trustworthiness in an instant.
In an AI Era, Leaders Must Own Their Words
Right now, as organizations reshape their workforce and integrate AI into everything from strategy to communication, people are looking to their leaders for information they can trust. A perfectly-polished AI-generated email doesn’t build that trust. You build trust through taking ownership of your words.
If you’re concerned about losing trust and influence as a leader, I’m now delivering a new keynote: The Believability Gap: Why Leaders Lose Trust.
And you can join me on this journey. I’m gathering small groups of senior leaders around the world to investigate this topic with me. If you want to be part of the inquiry, fill out this form: believability roundtable.
I’m continuing to explore this topic and uncovering new questions along the way. I’d love to hear what you’ve observed about trust and believability in your own leadership journey.
Until next week,

Believability in the Age of AI
What makes people believe you?
As AI makes communication faster, easier, and more polished, trust is becoming harder to earn. In this short video, I share some of the patterns I’m seeing in my research and conversations with senior leaders around the world.
