A Fresh Lens for Leaders
Certainty: How Great Bosses Can Change Minds and Drive Innovation explores how survival instincts shape workplace behavior and presents readers with practical leadership strategies that will build trust, inspire teams, and drive innovation. Why was this an important book for you to write?
Because I’ve seen firsthand—both at the CIA and in the private sector—how often leaders unintentionally trigger fear, uncertainty, and resistance in their teams. I tossed out everything I learned about leadership and management from West Point and Harvard Business School and started with human nature. I wrote Certainty to give leaders a fresh lens: to understand that the workplace is not just logical, it’s deeply emotional, instinctual, and biological. We’re wired to survive, and that wiring still shapes how we respond to change, authority, and feedback. I wanted to offer practical, brain-based strategies to help leaders build trust, lower fear, and lead in ways that align with human nature—not fight against it.
What were some ideas that were important for you to share in this book?
One key idea is that uncertainty is the enemy of innovation. When people don’t feel psychologically safe—socially, emotionally, or professionally—they shut down, they play it safe by clinging to the status quo, and creativity suffers. Another essential idea is that leadership is less about control and more about creating conditions where people feel seen, heard, and valued. A leader’s job is to unleash the best of human nature. I also wanted to show how simple brain-friendly tools, like open-ended questions, regular check-ins, and praise with purpose, can become part of a leader’s habitual behavior and make a real, lasting difference.
What is a common misconception people have about effective leadership?
That being a great leader means having all the answers or being the smartest person in the room. In reality, effective leadership is about asking better questions, listening deeply, and making people feel safe enough to contribute their best ideas. Too many leaders rely on authority and metrics, when what really drives performance is clarity, belonging, and trust.
What is one thing that you hope readers take away from Certainty?
That you don’t have to be perfect to be a great leader, but you do have to be intentional, and that means setting aside a small amount of time to reflect in order to devise a mental plan for the week. If leaders make small, consistent changes—like replacing feedback with praise and advice or being more transparent in times of uncertainty—they can dramatically increase trust, engagement, and innovation. The book shows that leadership isn’t about charisma—it’s about understanding what makes people tick and creating the conditions for them to thrive.

The dilemma. Our Stone Age brains are hardwired for survival and programmed to fear the unknown, yet the work world demands constant innovation. The enemy of better leadership is uncertainty deeply buried in the minds of your workforce.
The solution. In Certainty, Mears offers the answer: understand human nature. Work with it rather than pushing against it. Mears draws on neuroscience and psychology-plus compelling stories from his career-to offer practical leadership advice, including:
• Entertaining, science-backed explanations of how our brains think and how our primitive brains are colliding with the demands of the modern workplace
• New feedback, change management, and delegation tools to build an environment of certainty rather than of fear
• Fresh insights to overcome innate change resistance in yourself and others
• Time-saving ideas to empower yourself while empowering your employees
The results. You want loyalty, trust, and great performance from your team. We all do. With Mears’s guidance, you can identify the limitations and strengths of the human mind and create a dynamic and innovative workplace.
CERTAINTY: How Great Bosses Can Change Minds and Drive Innovation
Mike Mears’ Certainty: How Great Bosses Can Change Minds and Drive Innovation takes a deep dive into the human mind and how our survival instincts shape workplace behavior. The book is built around the idea that humans crave certainty, and uncertainty often triggers fear, resistance, and poor decision-making. Mears explores concepts like the “auto-brain,” which governs instincts and emotions, and the “focused-brain,” which helps us control those impulses. Through engaging anecdotes—some from his time in intelligence—he presents practical leadership strategies to build trust, inspire teams, and drive innovation. At its core, the book argues that great leaders don’t just manage—they create a sense of psychological safety that allows people to thrive.
One of the things I really appreciated about Certainty is how it strips leadership down to the basics of human nature. It’s not just about motivational speeches or company mission statements; it’s about how our brains are wired. Mears breaks down how we spend most of our day running on instinct, often without realizing it. His discussion on how humans resist change not out of stubbornness but because our brains are wired to see it as a threat felt like a lightbulb moment. He explains that the key to leading people through change isn’t brute force but creating a sense of security. The simplicity of that insight hit hard.
One of the book’s strengths is its clear and consistent message about how uncertainty triggers fear, reinforcing the importance of creating psychological safety. Mears emphasizes this idea throughout, ensuring it sticks with the reader. His anecdotes from intelligence and corporate leadership are captivating, offering unique insights from high-stakes environments. I appreciated the inclusion of case studies from everyday workplaces to showcase how these concepts apply across a broader range of industries.
One of my favorite sections was the one on “Mental Prompts,” which provides easy, actionable ways to create a culture of certainty. The “Vision Prompts” help clarify expectations, the “Inclusion Prompts” tap into our social bonding instincts, and the “Insight Prompts” encourage creative problem-solving. Mears makes a compelling case that small, consistent behaviors like genuine recognition or making sure everyone feels included can have a massive impact on a team. The example of CIA officer Renee, who created a high-performing unit in a war zone by focusing on trust and inclusion, was powerful.
Certainty: How Great Bosses Can Change Minds and Drive Innovation is an insightful, engaging read that makes leadership feel less like a skill you have to master and more like a mindset you can adopt. If you’re a leader (or aspiring to be one) and want to understand what truly motivates people, this book is worth your time. It’s particularly great for managers in high-pressure environments, but honestly, anyone who works with people will find something useful here. If you’ve ever been frustrated by resistance to change or struggled to inspire a team, this book will give you practical ways to flip that script. Highly recommended.
