Mark: Doctors tell a group of heart patients, "If you don't change your lifestyle—your diet, your exercise, your smoking—you will die." The patients all say they want to live. What percentage do you think actually makes the change? Michelle: Oh, wow. I mean, with stakes that high, it has to be most of them, right? Maybe 70 or 80 percent? Mark: You'd think so. The answer is shocking: only one in seven. One in seven people facing a literal life-or-death choice can actually follow through. That's not a willpower problem. It's an immunity problem. Michelle: One in seven? That’s terrifying. That’s a statistic that really sticks with you. Mark: It’s the exact statistic that kicks off the book we're diving into today: Immunity to Change by Robert Kegan and Lisa Laskow Lahey. Michelle: And we should say, these aren't just pop-psychology authors trying to sell a new framework. They're both highly respected developmental psychologists from Harvard. So when they talk about a psychological 'immune system,' they're coming from a place of deep, decades-long research. Mark: Exactly. They spent their careers trying to understand that one-in-seven problem. What they discovered is a hidden architecture in our minds that actively, and brilliantly, fights the very changes we say we want to make. And it’s not just about life-or-death situations. Think about every failed New Year's resolution, every piece of feedback at work you agreed with but never acted on. Michelle: Right, the classic performance review cycle. You get the feedback, you nod sincerely, you make a detailed plan… and then a year later, you’re having the exact same conversation. Mark: It’s the same phenomenon. The book argues that we all have one foot on the gas pedal, genuinely wanting to move forward, and one foot slammed on the brake, holding us in place. And today, we’re going to figure out what that brake is, why it’s there, and how to finally release it.

Michelle: Okay, so this idea of a psychological 'immune system' is fascinating. But isn't that just a fancy way of saying we're making excuses or we're just scared of change? Mark: That’s the conventional wisdom, but Kegan and Lahey argue it's much deeper and, strangely, more intelligent than that. It’s not a character flaw like laziness or a simple fear. It’s an active, brilliant system designed for self-protection. It’s like our mind has its own internal bodyguard that’s a little overzealous. Its job is to keep us safe from what it perceives as danger. Michelle: A bodyguard. I like that. So this bodyguard sees the change—like delegating more at work or being more open with a partner—as a threat? Mark: Precisely. And it will do anything to neutralize that threat, even if we consciously believe the change is good for us. The book is filled with examples. They talk about a study of year-end reviews at a company that took them very seriously. People would get emotional, make sincere pledges, and create elaborate plans for improvement. Michelle: I’ve been in that meeting. It feels very real in the moment. Mark: It does! But when the researchers checked back a year later, they found almost no significant, lasting change. The investment of time and emotion led to virtually nothing. The authors’ point is that the problem isn't a lack of desire. The people in that room wanted to change. The heart patients wanted to live. Michelle: So what’s the bodyguard protecting them from? In the case of the heart patients, what could possibly be more dangerous than dying? Mark: That’s the million-dollar question, and it leads to the core of their work. The 'danger' isn't external; it's internal. It’s a threat to our identity, to our way of making sense of the world. For some, changing a lifelong habit, even a deadly one, can feel like a kind of death in itself. Michelle: Wow. That reframes it completely. It’s not about choosing between a cigarette and a longer life. It’s about choosing between who I am now and a person I don’t recognize. Mark: Exactly. The book gives a few powerful examples of this. They tell the story of an Italian-American man who can't stick to a diet. Why? Because in his family, food is love. When he refuses his aunts' second helping of pasta, he's not just refusing calories; he's rejecting their love, his culture, his connection to them. His competing commitment is to feeling connected to his family. Michelle: Oh, I know that feeling. The guilt is a physical force. Mark: Then there's the story of the woman who keeps losing and regaining the same twenty pounds. When she loses the weight, she starts getting unwanted sexual attention from men, which she finds deeply disturbing because of past experiences. So she unconsciously regains the weight. Her hidden commitment isn't to being overweight; it's to keeping her relationships desexualized and feeling safe. Michelle: That’s heartbreaking. And it makes so much sense. Her behavior, which looks like self-sabotage from the outside, is actually a very smart, protective strategy. Mark: It's a brilliant strategy to manage a deep-seated anxiety. This is the central insight of the book. Our resistance to change isn't a bug; it's a feature. It’s the perfectly calibrated output of a hidden system. And until we can see that system, we're just spinning our wheels, blaming ourselves for a lack of willpower that was never the real problem. Michelle: Okay, so if there's a secret saboteur—or a well-meaning but misguided bodyguard—how do we find it? How do we pop the hood and see what's actually going on?

Mark: This is where Kegan and Lahey give us the tools. They developed a diagnostic they call the "Immunity Map," which is essentially a psychological X-ray. It’s a four-column exercise designed to make your hidden immune system visible. Michelle: An X-ray of the soul. I'm in. How does it work? Mark: Let’s walk through it with one of the book's most compelling case studies: Peter Donovan, a successful CEO of a financial services company. He's energetic, smart, and has built this company from the ground up. But the company is growing, and his leadership style is becoming a problem. Michelle: What's the problem? Mark: He can't delegate. He's a classic micromanager. He knows it, his team knows it, and he genuinely wants to change. So, that’s Column One of his map: his improvement goal. Michelle: Column 1: I will become a better delegator. Simple enough. Mark: Right. Now, Column Two is for the things you are doing, or not doing, that work against your goal. It’s about being brutally honest. Peter lists things like: "I give curt, dismissive responses when people bring me ideas," "I don't seek out others' opinions," and "I jump in to solve problems myself instead of coaching my team." Michelle: Okay, so he's basically describing all the classic symptoms of a micromanager. He’s aware of the behavior. Mark: He is. And this is where most change efforts stop. We identify the bad behavior and resolve to stop it. But Kegan and Lahey say that's like trying to cure an infection by just suppressing the fever. You have to find the source. That brings us to Column Three: the Hidden Competing Commitments. Michelle: The bodyguard's mission statement. Mark: Exactly. To get there, you ask yourself a crucial question: "If I imagine doing the opposite of my Column Two behaviors, what is the most frightening or uncomfortable or worrisome thing that comes to mind?" Michelle: So for Peter, that would be... what if he did listen to everyone's ideas and didn't jump in to solve things? What’s the fear? Mark: He digs deep and uncovers a few powerful fears. The fear of things not being done to his high standards. The fear of the company failing. The fear of looking incompetent. And these fears point to his hidden commitments. He realizes he has a powerful, unconscious commitment to having things done his way, and a commitment to feeling like the indispensable problem solver. Michelle: Whoa. So he's committed to being a better delegator, but he's also committed to being the guy who never lets anything fail. Those two things are in direct conflict. Mark: That's the immunity! One foot on the gas, one on the brake. He's a living contradiction. But it's Column Four that delivers the knockout punch. Column Four is where you uncover the Big Assumption. It's the worldview you hold that makes your competing commitments in Column Three feel like a matter of life and death. Michelle: The assumption that holds the whole system together. What was Peter's? Mark: To find it, you look at your competing commitments and complete the sentence: "I assume that if I were to stop [my competing commitment], then [the terrible thing] would happen." Peter’s Big Assumption is this: "I assume that if I am not the one in complete control, and if I am not seen as the indispensable problem solver, then I will be seen as having no value." Michelle: Oh, man. That hits hard. His entire sense of self-worth is tied up in being "the guy." So his micromanaging isn't a flaw; it's a brilliant, deeply ingrained strategy to protect his core identity. Mark: It's his armor. And you can't just tell someone to take off their armor without helping them see that the dragon they're fighting might be imaginary. The beauty of the map is that it lays it all out. Peter can see, "Of course I micromanage! Given my big assumption that my value comes from being the hero, my behavior makes perfect sense. It's the smartest thing I could be doing." Michelle: That's a huge reframe. It moves from self-blame to self-understanding. I wonder how many of us have a Big Assumption like that running our lives without us even knowing it. Like, "I assume that if I'm not always busy, I'm lazy," or "I assume that if I disagree with people, they won't like me." Mark: The book is full of them. A junior partner who plays it safe because he assumes that if he takes a risk and fails, he'll be seen as a fraud. A senior partner who can't stop being the hero because he assumes that's the only way he knows how to be. It's a universal pattern. Michelle: And what's truly mind-bending is that this isn't just an individual phenomenon, is it? You're saying entire teams, even whole companies, can have a shared immune system.

Mark: That's when the concept goes from a personal development tool to a powerful lens for organizational change. Groups develop collective immunities that are just as real and just as stubborn. Michelle: How does that even work? How can a group share a Big Assumption? Mark: It often manifests as an unspoken rule, a part of the culture that everyone feels but no one talks about. The book has this incredible story about a school district in Southern California. The leadership team was dedicated and hard-working. The student body was over 80 percent Latino, while the professional staff was over 80 percent white. Michelle: Okay, a common dynamic in many places. Mark: Their stated goal, their Column One, was to accelerate the academic achievement of their English Language Learners. They genuinely wanted these kids to succeed. But when they looked at their Column Two behaviors, they admitted things like, "We don't consistently hold high expectations for our ELL students." Michelle: So, a classic case of saying one thing and doing another. What was their competing commitment? What were they protecting? Mark: This is what makes the story so powerful. The group really struggled to name it. The conversation was stuck. Then, overnight, one of the assistant superintendents, who was Latino, had a breakthrough. He came back the next day and said, "I know what our competing commitment is. The hardest thing for us to talk about in this mostly Anglo group is race. We are deeply committed to preserving what I'm going to call a 'pobrecito culture.'" Michelle: Pobrecito... like, "poor little thing." Mark: Exactly. A culture of pity. He said they were so full of protective concern and sympathy for these students and their difficult lives that they were afraid to "put more weight on their little backs." Their competing commitment was to protect the students from the perceived burden of high expectations. Michelle: Wow. That is just... heartbreaking. And so powerful. Their 'love' and 'concern' were the very things holding the students back. It wasn't malice at all. It was a misguided form of compassion. Mark: It was a collective immunity born from good intentions. Their Big Assumption was something like, "We assume that these students, given their circumstances, cannot handle high expectations, and that pushing them will only lead to failure and suffering." Michelle: And once that's on the table, you can actually talk about it. You can start to challenge it. You can ask, "Is that really true? What evidence do we have? What if the opposite is true—what if high expectations are actually a sign of respect?" Mark: That's the path to overcoming the immunity. You don't just try to change the behavior—"Hold higher expectations!"—you design small, safe experiments to test the Big Assumption. Maybe you pilot a program with one class where you raise the bar and provide extra support, and you collect data on what actually happens. Does it crush them, or do they rise to the occasion? Michelle: You treat the assumption like a scientific hypothesis instead of an absolute truth. Mark: You got it. You move from being subject to your assumptions to being able to look at them as objects of reflection. That shift is the essence of mental development. It's how we grow. And it's how organizations can get unstuck from problems they've been trying to solve for years.

Mark: So whether it's an individual CEO like Peter, who's afraid he has no value without being the hero, or an entire school district operating under a 'pobrecito' culture, the pattern is the same. Our resistance to change isn't stupidity or weakness. It's a deeply intelligent, self-protective system built on powerful, often invisible, assumptions about how the world works and who we are. Michelle: It completely changes how you look at being "stuck." It’s not a moral failing. It’s a design feature of being human. The book gives you a blueprint to your own internal operating system, showing you the hidden code that’s been running in the background. Mark: And the most hopeful part is that once you can see the code, you can start to rewrite it. You can challenge the assumptions, run the experiments, and build a new, more expansive system that can handle the changes you want to make without triggering all the internal alarms. Michelle: It really makes you stop and ask: What's the one thing I say I want to change, but never do? And what am I really committed to that's keeping me stuck there? Mark: It's a profound question. The book is really an invitation to that kind of deep self-inquiry. We'd love to hear what this brings up for you. Join the conversation and share your thoughts with the Aibrary community.
