What if leadership started with how you think?

In this edition of the Business Insights Series , I had the pleasure of speaking with Darren Stevens, a psychologist, academic, and founder of the Institute for Adult Development (IAD). Darren is one of those rare thinkers who bridges theory and application without breaking stride. He’s also the author of an ambitious book series titled The Constructed Mind, which includes titles like Thinking Deliberately, Coaching Deliberately, and Leading Deliberately. Through these books and his workshops, Darren offers a robust set of tools for professionals who want to elevate their thinking, teaching, coaching, or leadership. His mission is ambitious: to transform how we understand growth, coaching, and leadership through the lens of cognitive development and self-awareness.

Darren developed his groundbreaking framework during his PhD in psychology, challenging conventional coaching models that overlook the developmental levels of thinking. What began as a solo research project has since evolved into an international movement, attracting collaborators and adopters across Europe, Australia, and Africa. IAD’s tools and workshops are being used in universities, executive leadership coaching, and even in the rethinking of HR and project management.

Darren’s approach blends academic rigor with practical, human-centered insight. It’s grounded in research but designed to be applied in real-world conversations, decisions, and relationships. We spoke about everything from the implications of developmental mismatches in coaching, to the struggles of building a structure around a grassroots collective, to his love-hate relationship with marketing.

Let’s explore what makes Darren’s work so timely and how it might just change the way we think about thinking.

A Framework That Coaching Bodies Couldn’t Validate

The story begins with Darren’s realization that existing coaching organizations couldn’t make sense of his framework. These organizations often focused on standardized methodologies and overlooked the deeply personal and psychological dynamics between coach and client. Darren identified a critical blind spot: developmental mismatch. If a coach is operating at a lower level of cognitive complexity or self-awareness than their client, their ability to guide or support that client becomes fundamentally limited.

“None of them could validate my approach… So I created the Institute for Adult Development to validate my approach.”

This insight led to the birth of the Institute for Adult Development (IAD), a platform designed to explore, refine, and expand an alternative way of understanding growth that traditional certifying bodies had not yet addressed. The IAD has since evolved into a collaborative space, part think tank, part training ecosystem, and part community of practitioners, who are passionate about developmental theory and its practical impact.

What anchors the work is a diagnostic tool called the Identity Compass. It decodes 50 cognitive shortcuts people use in everyday thinking and decision-making, offering a more granular look at how someone operates mentally. This profiling becomes the cornerstone of IAD’s training programs, giving coaches and facilitators a reliable way to assess and elevate developmental levels in others.

“It’s really a group of like-minded people wanting to use developmental levels to gauge the development of their clients.”

From that foundational insight to global engagement, Darren’s research has moved from academic theory to hands-on practice, helping professionals in diverse fields rethink how they understand capability, growth, and communication.

Why Capacity Matters More Than Titles

One of the most challenging insights from Darren’s work is the idea that someone in a position of power isn’t necessarily better equipped to lead. Authority doesn’t always mean ability. Darren calls this pattern the Authority Superiority Syndrome, a cognitive trap where people mistake rank or seniority for superior intelligence or capability.

“By virtue of the fact that someone is at a higher rank… they think they’re cleverer than you. It’s not true.”

This phenomenon plays out in all kinds of teams. Executives may ignore their more junior staff’s insights simply because they assume that being in charge means being the smartest. In high-stakes environments, this leads to poor decision-making, micromanagement, and missed opportunities to leverage the real expertise in the room. Darren’s insight challenges the status quo that power equals wisdom.

He emphasizes that real leadership requires the ability to step outside one’s mental shortcuts and consider multiple viewpoints, even those that feel unfamiliar or inconvenient. This is where cognitive complexity comes in. Leaders with higher developmental awareness are better at integrating various perspectives and making decisions that reflect long-term thinking, empathy, and strategic flexibility.

“It’s that kind of leader that’s going to be capable of pulling in the right team members and utilizing their skills, their capacities, their capabilities more effectively.”

Darren connects these ideas to Robert Kegan’s levels of adult development, showing how leaders evolve from enforcing rules to authoring their own frameworks for thinking and relating. This kind of growth influences both individual performance and how organizations function, collaborate, and innovate.

Development Means Learning to See the Problem Differently

When coaching clients or workshop participants, Darren supports clients and workshop participants in both solving their immediate problems and learning how to reframe those problems through different levels of complexity. It’s a method that pushes people beyond the surface level of their issues and into a more nuanced, layered exploration of what the problem truly is.

“The problem is never the problem. The problem is how they construct the problem.”

In Darren’s “Three Leaders Program,” participants are guided through a single business or interpersonal challenge written from three distinct cognitive perspectives, what he refers to as level 2, level 3, and level 4 thinking. On day one, participants address the problem using straightforward, procedural thinking. On day two, they revisit the same problem but with added social-emotional nuance and broader relational awareness. By day three, they’re challenged to approach the issue with the highest level of abstraction, long-term vision, and multidimensional thinking.

“Some of them you’ll lose when we talk about it on the third day, but the majority of them will move with you, grow with you…”

This progression highlights how a single situation can morph based on the lens through which it’s viewed. Darren uses this to show that real growth comes from expanding the way we frame the questions, not simply from seeking answers. People often experience “aha!” moments when they realize that their original way of understanding the issue was overly simplistic or based on unconscious assumptions.

By learning to see problems through multiple developmental lenses, leaders, coaches, and facilitators gain not only deeper insight but also practical strategies that are more aligned with complex, real-world dynamics. This idea is backed by cognitive reframing research, which shows that learning to reinterpret problems from more constructive angles can reduce brain activity in the threat detection center while increasing executive function and problem-solving. Neuroscientific studies demonstrate that reframing not only supports emotional regulation, but also enhances decision-making by activating higher-order thinking.

Similarly, research on metacognitive thinking aligns with Darren’s methodology: by helping individuals monitor and control their cognitive processes, frameworks like the Three Leaders Program improve learning, leadership, and performance. Their actions are shaped by how they think through what they do, and by the frameworks they use to interpret complexity and context.

Scaling a Theory with No Hierarchy

While Darren’s framework is rigorous, the way the Institute operates reflects the same open and growth-oriented spirit that defines his theory. The IAD avoids top-down management in favor of shared purpose and a collaborative energy. Members from across the globe adapt the tools to suit their local cultures, industries, and professional landscapes. This decentralized approach has created a dynamic, international community committed to applying developmental thinking in real-world contexts.

Research on authority dynamics in organizations supports this kind of structure. Studies show that people hold unconscious internal models of authority, ranging from dependence to counterdependence to interdependence. The interdependent model, which aligns with IAD’s collaborative design, is linked to viewing authority as a source of security, growth, and autonomy. This perspective fosters healthier relationships and supports both individual and collective development.

“The IAD is mine… but it’s more of a collective. There’s not one person at the top.”

Darren has intentionally fostered a culture where leadership is distributed and initiative is welcomed. While formal structures are still evolving, he has built a strong foundation by empowering people who share the mission to take ownership and contribute their strengths. That kind of trust has enabled IAD to grow organically, and it’s now entering a more refined phase of development.

“I’m not very good at managing things… But it is taking shape.”

He’s currently working on codifying key operational elements, such as intellectual property protections and royalty agreements, to ensure that the value created through IAD’s courses and ideas is respected and sustainable. This move reflects a maturing organization that remains rooted in collaboration while preparing for long-term impact.

At the heart of this evolution are three flagship programs: Next Level Coaching, Meta Model, and the Three Leaders Program. These offerings have become the centerpiece of IAD’s learning experience and are in the process of being mapped to CPD accreditation for professional recognition in the UK and Europe.

“I talk at a level that’s too high for marketing… which means I don’t get the right marketing.”

One of the ongoing frontiers is communication. Darren’s ideas are rich, complex, and often ahead of their time, so translating them for wider audiences is an active focus. Rather than a weakness, this is simply the next step in the IAD’s growth: building a message that matches the strength of its mission. With the first IAD international conference approaching in Barcelona, Darren and his collaborators are setting the stage for a future where deliberate thinking is taught, practiced, and integrated into how we shape better organizations, relationships, and results.

Thinking Is a Practice, Not a Trait

At the heart of Darren’s work is a belief that thinking can be improved, and that it matters everywhere, from coaching to parenting to project management. His approach focuses on helping people become more aware of how they think and why that awareness matters in their everyday interactions.

“We think about our thinking.”

That deceptively simple statement encapsulates the core of Darren’s framework. It applies across disciplines, cultures, and professions, not limited to academics or coaches. His work has found a natural home in adult learning environments where students are navigating the complexities of leadership, conflict, and decision-making in real time.

In academia, Darren brings this theory into action. He teaches mature apprenticeship students, often professionals in their 40s and 50s, how to apply cognitive complexity in leadership, human resources, and organizational behavior. These students bring their own lived experiences, and Darren helps them reinterpret those through developmental theory. Many of them report back after class with stories of personal insight: clearer communication with a colleague, a new way to handle conflict at home, or a shift in how they approach management.

“I apply my theory, my framework pretty much everywhere… and it’s taken off.”

His book, “Thinking Deliberately,” lays out these ideas in a structured way, while the upcoming “Leading Deliberately” will focus on applying the same concepts to organizational leadership and strategic influence. Darren’s growing body of work is bridging the gap between theory and practice, making abstract developmental ideas accessible and applicable to everyday professional life. It’s this practical translation that has made his framework resonate so strongly across different sectors and educational settings.

The Thinking Behind the Thinking

Darren Stevens is building something that goes beyond coaching, it’s a movement toward more thoughtful, deliberate adult development. His approach centers on mindset as much as it does on methods. He invites us to consider not just what we do in leadership or development, but how we come to see ourselves and others. That mindset shift is powerful and rare.

As the Institute for Adult Development edges into a more structured phase, with partnerships expanding across continents and the first international conference on the horizon, the momentum is real. Yet Darren knows that the success of this movement will depend on his willingness to evolve as well. That evolution doesn’t have to mean doing it all himself, in fact, part of growth is recognizing when someone else might be better suited to lead a specific effort.

“I know I need to transform myself… but I think someone else might be better at doing that part.”

That kind of awareness, the humility to recognize your own limits, and the courage to invite others into the mission, is part of what makes Darren’s work so compelling. He exemplifies development in both what he teaches and how he lives and works alongside others. And that, more than anything, signals the integrity and relevance of the path he’s helping to chart.

Ready to Think Differently?

The insights from this conversation with Darren show us that thinking, real, reflective, development-oriented thinking, plays a vital role in leading well, coaching wisely, and growing with purpose. From cognitive mismatches in coaching to hidden assumptions in leadership, Darren’s work offers a roadmap to navigate complexity with clarity. That kind of clarity builds over time through frameworks that help people make sense of themselves, their choices, and the systems they move within.

By applying developmental theory in both strategic and everyday contexts, Darren is inviting professionals to become more intentional, more deliberate, about how they engage with others and themselves. Whether you’re leading a team, guiding a client, or just trying to become a better thinker, this conversation is a reminder: growth involves both intentional pursuit and thoughtful design.

If you’re wondering how to bring frameworks like these into your team, business, or coaching practice, let’s talk.
