A New Developmental Theory of Human Flourishing

What if flourishing depends not only on what we know, but on how healthier meanings develop and become enduring ways of living?

Human flourishing depends not only on what we know, but on the quality of the meanings through which we learn to live what we know.

In the first two articles in this series, I invited readers to consider a question that has fascinated me for much of my professional life: Why do we so often struggle to live according to what we already know? We know a great deal about what contributes to healthier lives. We know that trust strengthens relationships and that dignity matters. We know that people flourish when they feel safe, valued, appreciated, and meaningfully engaged. We understand the importance of healthy relationships, purpose, compassion, hope, and well-being. And yet knowing these things does not guarantee that we will live accordingly.

This is hardly a new observation. More than twenty-five years ago, Stanford professors Jeffrey Pfeffer and Robert Sutton gave a version of this problem a memorable name: the knowing-doing gap. In their influential book The Knowing-Doing Gap: How Smart Companies Turn Knowledge into Action, they examined why organizations so often fail to act on what they already know. They identified barriers such as fear, internal competition, and the tendency to substitute talking and planning for actually doing. (Stanford Graduate School of Business)

Their contribution remains important. Pfeffer and Sutton also recognized an interesting problem: knowing about the knowing-doing gap is itself not enough to close it. Understanding why the gap exists may help us act, but understanding alone still does not guarantee action. (East Central University)

More than twenty-five years later, the larger human problem remains. We continue to invest enormous time and resources in education, leadership development, coaching, organizational change, health and well-being, and personal development. We continue learning more about what helps people and organizations flourish. And still, we often struggle to live what we know.

Why?

I do not believe the answer is simply that we need more knowledge. Knowledge matters enormously. Nor does the persistence of the problem diminish the work of those who have studied the knowing-doing gap and proposed ways to address it. Instead, I believe it invites us to ask another question: What happens between knowing something and living it?

Between Knowing and Doing

Meaningful Purpose Psychology proposes that between what we know and how we live is something extraordinarily important:

Meaning.

Human beings do not simply receive information and act on it. We interpret it. We connect it with what we already believe and compare it with previous experiences. We consider what it means for us and for the people around us. We may experience it as helpful, threatening, trustworthy, irrelevant, inspiring, or uncomfortable.

Sometimes we embrace what we learn. Sometimes we resist it. And sometimes we sincerely agree with something intellectually while continuing to live by meanings formed years—or even decades—before we acquired that knowledge.

Consider something as simple as receiving help. One person may interpret asking for help as a sign of wisdom: I don't have to know everything. Other people can help me grow. Another may have learned: If I ask for help, people will think I'm incapable. Both people may understand perfectly well that collaboration is beneficial. Both may even teach others that asking for help is a strength. Yet when the moment comes to ask for help, they behave very differently.

Why?

The difference may not lie in what they know. It may lie in what asking for help means to them. That distinction is important. Perhaps one reason beneficial knowledge does not reliably become beneficial action is that new knowledge enters an existing system of meaning.

We are not blank pages waiting for better information. We bring our histories, relationships, assumptions, expectations, fears, hopes, values, and previous interpretations with us. They help shape what new information means to us. This leads to the developmental question I want to explore in this article:

How do healthier meanings develop—and how do they become established enough that healthier ways of living become increasingly natural and enduring?

I believe that question takes us beyond the knowing-doing gap and toward another important part of human development: how meanings develop and become part of how we live.

Every Meaning Has a History

None of us is born with a complete understanding of ourselves, others, or the world. We learn what things mean over time. Some of those meanings are taught to us directly. Others develop more quietly through experience. We watch how people treat one another. We notice what earns approval and what draws criticism. We learn what feels safe and what seems risky. We listen to the stories our families tell, absorb lessons from our cultures and communities, and draw conclusions from our successes, disappointments, relationships, and mistakes.

Gradually, interpretations take shape.

A child who is repeatedly criticized may begin to believe, “I'm not good enough.” Someone who has been betrayed may come to believe, “People cannot be trusted.” A person praised mainly for achievement may learn, “My worth depends on what I accomplish.” Someone raised in a loving and supportive home may develop a very different meaning: “I can depend on people when I need them.” These meanings do not appear from nowhere. They have histories.

Meaningful Purpose Psychology calls the experiences and influences that contribute to the development of our meanings Meaning Antecedents. They may include our families, relationships, culture, education, successes and failures, painful experiences, role models, and many other aspects of our lives. But experiences do not determine meaning in a simple or predictable way. Two people can go through similar events and understand them very differently.

Our experiences influence us, but the meanings we derive from them help shape what we carry forward.

What matters, then, is not only what happened, but also what it came to mean. Our existing meanings also influence how we understand new experiences and information. They can help us recognize something valuable—or make it harder for us to see. But understanding a meaning's history does not mean we should continue trusting it. That brings us to another important question: Does this meaning still deserve my trust?

Not Every Meaning Deserves Our Trust

If our meanings develop over time, another question naturally follows: Should we trust a meaning simply because we have believed it for a long time?

Probably not.

Some meanings serve us well. They help us understand reality more accurately, build healthier relationships, make wiser decisions, and contribute to our own flourishing and the flourishing of others. Other meanings may have made sense at one point in our lives but no longer serve us well. Some may have developed from incomplete information. Others may reflect assumptions we inherited from our families, cultures, communities, or past experiences without ever examining them carefully. And some meanings may simply be wrong.

Consider a person who learned early in life: “If I disappoint people, they may stop loving me.” That meaning may have developed for understandable reasons. Perhaps approval was inconsistent at home. Perhaps affection seemed connected to achievement or good behavior. Over time, pleasing others became a way to feel safe and accepted. Years later, the person may come to understand that healthy relationships require boundaries. They may have read about the importance of saying “no”. They may even encourage friends to stand up for themselves. Yet when someone asks them for something they do not want to do, they still find themselves saying yes.

Why? The older meaning may still be guiding the response.

But compassion does not require us to continue trusting a meaning simply because we understand where it came from. We must also ask: Does this meaning still deserve my trust? 

This is where Meaning Quality becomes important. Meaning Quality helps us examine whether the meanings we live by deserve our trust. Are they reasonably consistent with reality? Do they promote human flourishing? Do they work well with the other healthy meanings we hold? And are we sufficiently aware of the meanings shaping us and those emerging around and within us? Meaningful Purpose Psychology organizes these questions around four dimensions: Intelligence, Health, Harmony, and Awareness.

The purpose is not to make us suspicious of everything we believe. It is to help us become wiser about what we trust. Meanings do more than help us understand our experiences. They can influence what we notice, how we interpret situations, what choices seem reasonable, and how we respond. In other words, meanings can begin to guide how we live. And if meanings can guide how we live, we need a way to examine whether they deserve to do so.

That is the work of Meaning Validation.

Examining the Meanings We Live By

Meaning Validation is the intentional practice of examining whether the meanings guiding our lives deserve our confidence. Validation does not mean proving that what we already believe is correct. It means being willing to examine a meaning honestly—even when what we discover may challenge us.

Sometimes validation strengthens a meaning we already hold. Sometimes it helps us refine an incomplete one. And sometimes it asks us to let go of a meaning that no longer deserves our trust. That can be difficult because meanings are not always just ideas. They may be connected to our identities, relationships, families, cultures, faith traditions, political views, hopes, fears, and experiences.

The Examiner Must Also Be Examined

Whenever we examine a meaning, we naturally want to believe that we are examining it objectively. But the person doing the examining also has meanings. Our experiences, loyalties, fears, hopes, identities, values, and assumptions can influence what we are willing to question—and what we instinctively protect.

Meaning Validation therefore asks us to examine not only the meaning in question but also what may be influencing how we examine it.

“What is influencing not only what I believe, but also what I am willing to examine?”

Sometimes the examination itself produces a reaction. Over the years, when I have invited people to examine deeply held beliefs, I have sometimes heard responses such as:

“You're asking me to question my faith.”

“You're asking me to question everything my parents taught me.”

“You're asking me to become skeptical.”

“You're saying I can't trust myself.”

These reactions do not prove that the belief being examined is wrong. But the reaction itself means something. A defensive reaction may reveal another meaning at work—perhaps a fear of disloyalty, uncertainty, rejection, loss of identity, or what might have to change if the examination leads somewhere unexpected.

Resistance is therefore not simply something to overcome. It is meaningful information to understand. Instead of asking only, “Why won't this person change?” the logoteleologist also asks: “What meaning makes this response understandable from the person's point of view?” And when change is repeatedly resisted: “What meaning is preventing what works from working?”

Resistance becomes information to examine—not proof that the person is wrong. A defensive reaction tells us something about the person's relationship to examination. It does not settle the truth of what is being examined.

Meaning Validation therefore requires courage, compassion, and integrity. Courage enables us to follow the examination wherever the evidence leads. Compassion helps us understand why a meaning developed without condemning ourselves—or anyone else—for developing it. Integrity asks more of us: to live according to what we discover.

We can courageously examine a meaning and compassionately understand where it came from, but if we ignore what we discover, little changes. Meaning Validation invites us to bring our lives into greater alignment with reality rather than deny, avoid, or rationalize what we have come to understand. Sometimes that means strengthening a meaning that has served us well. Sometimes it means refining an incomplete one. And sometimes it means letting go of a meaning that no longer deserves our trust.

A person's worth is never determined by the quality of their meanings. Meaning Quality helps us evaluate meanings, not the inherent worth of the person who holds them.

Meaningful Purpose Psychology seeks truth with intellectual rigor and applies it with unwavering compassion, because the goal is not simply to understand people more accurately—it is to help them flourish more fully.

The goal is not to become skeptical of everything we believe, nor is it to endlessly question or judge ourselves and others. The goal is much simpler: to place greater confidence in meanings that deserve our trust—and to become increasingly willing to revise those that do not.

As we practice this over time, healthier meanings can become easier to recognize and more readily available when we need them.

Learning to See More Clearly

Something begins to change when we repeatedly examine our meanings, strengthen those that deserve our trust, and become more willing to revise those that do not. We begin to see differently.

Think about something you understand today that you wish you had understood years ago. Perhaps you recognize unhealthy relationship patterns more quickly. Maybe you have learned that disagreement need not mean rejection, that asking for help is not a sign of weakness, or that saying “no” can sometimes be an act of respect—for yourself and others.

Once we understand something more clearly, we may wonder: How did I not see this before? The information may have been available to us all along. What changed was our ability to recognize its meaning. Meaningful Purpose Psychology calls this developing capacity Meaning Lucidity.

Meaning Lucidity is the growing ability to perceive ourselves, other people, and reality more clearly through increasingly healthy meanings. As healthier meanings become easier to recognize and more readily available, they can increasingly guide how we understand and respond to life.

This is more than knowing the right answer. We may know we should remain calm during a disagreement. But when someone says something that feels insulting, that knowledge may quickly give way to another meaning: I'm being disrespected. With greater Meaning Lucidity, other meanings may become available: Maybe I misunderstood. Perhaps there is something I don't know. I can disagree without attacking. I can pause before responding. The situation has not changed. What becomes available to guide us has.

Meaning Lucidity does not mean we will always see clearly or make the right choice. Difficult emotions will not disappear. Old meanings may still return, especially when we are tired, frightened, angry, or under pressure. The goal is simpler: to make healthier meanings more available when we need them most.

Seeing Clearly Is Not Always Comfortable

There is another side of Meaning Lucidity that deserves compassion. Seeing ourselves more clearly can reveal things we would rather not face. We may recognize mistakes we have repeated. We may see how our behavior affected someone we love. We may reconsider something we once believed with great confidence. We may remember moments that bring regret, embarrassment, sadness, or shame. Greater clarity may also bring painful experiences from our past back into awareness. That is why Meaning Lucidity is not an invitation to judge ourselves more harshly. It is an invitation to understand ourselves more truthfully and to respond more compassionately.

Instead of asking: What's wrong with me? Why would I have done something so irrational? we can ask: What meaning made that response understandable from my point of view at the time?

Understanding does not excuse harmful behavior or make an unhealthy meaning healthy. It helps us see what was operating so that we can learn from it, make amends where appropriate, forgive ourselves and others when possible, and choose healthier meanings going forward.

Sometimes what comes into awareness may be more than we should work through alone. Personal development has its limits, and recognizing those limits is itself an act of wisdom and self-care. When painful experiences or emotional distress become difficult to manage, seeking support from a qualified mental health professional may be the wiser and more compassionate path.

Another important point is that Meaning Lucidity is about growth, not perfection. We will still misunderstand situations and make mistakes. What can change is our ability to recognize healthier meanings and allow them to guide us more often. And when healthier meanings become more readily available, something else becomes possible: Clearer seeing can increasingly become healthier living.

That brings us to the next question: How does what we increasingly see and understand become part of who we are and how we live?

From Seeing to Living

Seeing more clearly matters, but clearer seeing is not the destination. What we see and understand must increasingly shape how we live. This brings us back to the knowing-doing gap. Knowing something does not guarantee that we will act on it. Lasting change requires more than moving directly from knowledge to action. Healthier meanings must become trusted and accessible enough to guide how we live.

I describe this developmental movement simply as: SEE → BE → DO

We first learn to SEE ourselves, others, and reality more clearly. What we repeatedly see and come to trust can begin to shape who we BEcome. And who we are becoming increasingly influences what we DO—how we choose, respond, relate, lead, work, and live.

The sequence matters. We often approach change by starting with the DO: communicate better, listen more, set boundaries, be more compassionate, take better care of ourselves. These may all be excellent recommendations. But when the meanings guiding us remain unchanged, healthier behavior can be difficult to sustain.

Imagine a leader who learns that psychological safety improves team performance. She attends the training, understands the research, and agrees that people should feel safe speaking honestly. She knows what to do.

But suppose she still interprets disagreement as a challenge to her authority.

When someone questions her decision in an important meeting, which understanding is most likely to guide her response? The principle she learned in training? Or the meaning that tells her: If I allow people to challenge me openly, I will lose their respect. This is why—in logoteleology—lasting change requires more than teaching people what to do.

According to this science, we must also ask: What meaning makes the current behavior understandable from the person's point of view?

And then: What healthier meaning would make a healthier response increasingly natural?

This is how, in Meaningful Purpose Psychology, healthier meanings can begin to become healthier ways of living.

Becoming What We Understand

As healthier meanings become clearer and more deeply trusted, they can influence more than individual choices. They can become part of who we are becoming. Someone who once thought, “Asking for help shows weakness,” may gradually come to see interdependence as a strength. Someone who once interpreted disagreement as rejection may learn to see honest disagreement as part of a healthy relationship.

Over time, the healthier response may require less effort because the person is no longer simply performing a better behavior. The healthier meaning becomes part of how they understand themselves and the situation. They are not only doing something differently. They are becoming different.

This does not mean change becomes automatic or effortless. Old meanings can remain powerful, and healthier meanings need to be practiced and reinforced. But something fundamental has changed. We are no longer simply working to behave differently. We are becoming someone for whom healthier ways of living increasingly make sense.

This is an important part of what I mean by Logoteleological Development. Human development involves more than acquiring knowledge or learning new skills. It also involves developing healthier meanings that shape how we understand ourselves, others, and reality—and increasingly living by them.

From Personal Flourishing to Helping Others Flourish

There is one more step in this developmental journey. Human flourishing cannot end with ourselves. Much of psychology understandably focuses on the self: self-awareness, self-regulation, self-efficacy, self-esteem, self-compassion, and self-actualization. These concepts have contributed enormously to our understanding of human development. Meaningful Purpose Psychology does not reject them. It asks us to extend them.

What if becoming a healthier self is not the final destination?

We live among other people. Who we become affects them. Our meanings become visible in how we listen, respond, lead, disagree, support, and care for others. Our presence can create experiences that contribute to another person's flourishing—or diminish it.

Hence, the question is no longer only "Who am I becoming?" It also becomes: “Who am I becoming in relation to others—and what do others experience because I am here?”

That takes us from personal flourishing toward meaningful contribution. In Meaningful Purpose Psychology, a healthier identity is therefore not only about feeling better about myself, becoming more capable, or achieving my goals. It is also about becoming someone whose presence increasingly contributes to the flourishing of others.

This is where love becomes especially important in Meaningful Purpose Psychology. Love, as expressed through The Meaningful Path, moves us beyond ourselves. It asks us to care not only about our own flourishing, but also about the flourishing of others.

Compassion is one way love is expressed: seeking to understand people truthfully while responding to them with dignity and care. In this sense, healthier development changes not only how we experience life. It changes what other people may experience because of us. In Logoteleology, the developmental question therefore expands. It is no longer only: “How can I flourish?” It also becomes: “How can who I am becoming help others flourish?”

That logoteleological question brings us to the applied developmental practice I call THRIVE™.

THRIVE™ is an applied practice within Meaningful Purpose Psychology that helps turn healthier meanings into healthier ways of living with others.

It asks us to increasingly:

T — Treat every person with dignity

H — Help people feel safe

R — Raise well-being

I — Improve human flourishing

V — Value and appreciate

E — Encourage meaningful engagement

These are simple ideas. Most of us already know they matter. That is precisely the point. THRIVE™ does not assume that humanity needs another list of things we should know. It asks the harder developmental question: “How do the healthy meanings we already recognize become increasingly part of who we are and how we live?”

The goal is not perfection. It is practice.

As healthier meanings become clearer, more trusted, and more available, we can practice them in everyday life. Over time, healthier ways of seeing can increasingly become healthier ways of being and doing.

SEE → BE → DO

Over time, something beautiful can happen. We become more than people who know what contributes to human flourishing. We increasingly become people whose presence contributes to it. In Meaningful Purpose Psychology, I describe this aspiration as becoming a Walking Solution—someone whose way of living increasingly contributes to the flourishing of others.

So, What Is the Developmental Theory?

At this point, the pieces come together. Meaningful Purpose Psychology proposes that human flourishing depends not only on acquiring healthier knowledge or learning better behaviors. It also depends on the development of healthier meanings through which we understand ourselves, other people, and reality.

Those meanings have histories. Meaning Antecedents help us understand how they developed.

Not every meaning deserves our trust. Meaning Quality helps us examine which ones do.

Meaning Validation helps us thoughtfully examine, strengthen, refine, or revise the meanings guiding our lives.

As healthier meanings become clearer, more trusted, and more available, Meaning Lucidity helps us increasingly see ourselves, others, and reality through them.

What we increasingly SEE can become part of who we BEcome, and who we are becoming can increasingly shape what we DO. Through THRIVE™, healthier meanings can then be practiced in everyday life—not only for our own flourishing, but also for the flourishing of others.

This is what I mean by Logoteleological Development: the ongoing development of healthier meanings that help us see more clearly, become healthier people, live healthier lives, and contribute more fully to human flourishing.

The theory can therefore be expressed simply:

Healthier Meanings → Clearer Seeing → Healthier Becoming → Healthier Living → Greater Human Flourishing

Growth, Not Perfection

Human development does not happen in a straight line. We continue to learn throughout life. New meanings develop. Older meanings are challenged. Some become stronger. Others need to change. And sometimes old meanings return when we are tired, afraid, angry, or under pressure. That is part of being human.

The goal is development, not perfection. Healthier meanings do not instantly produce flawless behavior. Rather, through Meaning Validation, Meaning Lucidity, and practice, healthier meanings can increasingly guide how we see, become, and live.

Sometimes we will get it right. Sometimes we will not. What matters is developing our ability to recognize what is happening, learn from it, and choose healthier meanings going forward. Not perfectly, but increasingly. Human flourishing is not a destination we finally reach. It is something we can increasingly learn to experience, practice, and contribute to throughout our lives.

From Knowing Better to Living Better

More than twenty-five years after Pfeffer and Sutton highlighted the knowing-doing gap, the challenge remains. We still need knowledge. We need good science, education, leadership, therapy, coaching, and ideas about what helps people flourish. But knowing what works is not enough. We also need to understand what happens between knowing and living.

What does this new knowledge mean to us? What existing meanings does it encounter? Which meanings deserve our trust? Which might be getting in the way? And what might happen if healthier meanings were more readily available to guide us when we need them most? These are some of the questions that led me to develop Meaningful Purpose Psychology, scientifically known as Logoteleology. They are also at the heart of my forthcoming book, THRIVE™: The Meaningful Purpose Field Guide, where I explore these ideas more deeply and, importantly, how we can put them into practice. Because ultimately, the goal is not simply to know more about human flourishing. It is to increasingly live in ways that create it—for ourselves and for others.

Perhaps that is one way we begin closing the knowing-doing gap: not simply by learning more about what works, but by developing healthier meanings through which what we know can increasingly become who we are and how we live.

Continue the Conversation

If these ideas have encouraged you to think differently about the meanings shaping your life, work, leadership, or organization, I invite you to continue exploring Meaningful Purpose Psychology (i.e., Logoteleology). My forthcoming book, THRIVE™: The Meaningful Purpose Field Guide, will provide a practical guide for examining the meanings we live by, developing greater Meaning Lucidity, and increasingly turning healthier meanings into healthier ways of living.

If you would like to explore how these ideas could help you or your organization, I also welcome conversations about coaching, leadership and team development, training, and organizational consulting. Whether the goal is personal growth, healthier leadership, stronger relationships, or organizational flourishing, the starting question is often surprisingly simple: What meanings are shaping how we see, become, and live?

And perhaps an even more important question follows: Are those meanings helping us flourish—and helping others flourish because of our presence?

What Would Change If We Understood How Meaning Develops?

If meanings help shape how we see ourselves, relate to others, make decisions, lead, and live, what could happen if we became better at understanding how those meanings develop? In the next article, we will explore what this could mean for individuals, relationships, families, workplaces, organizations, and society. Because understanding how meaning develops is not only about understanding ourselves. It may also help us create healthier conditions for others to flourish.
