There is a course at Stanford Graduate School of Business that students regularly describe as the most transformative experience of their MBA. It is not a finance class. It is not a strategy seminar. It is a course called Interpersonal Dynamics — and at its center is something called the T-Group.

If you have never heard of a T-Group, you are not alone. It is not widely marketed. It does not have a flashy framework or a bestselling book behind it. And yet, for more than six decades, it has quietly been one of the most powerful tools for developing leaders who can truly connect with the people around them.

Here is what we have learned from facilitating T-Groups for leaders across Vietnam and Southeast Asia — and why we believe this methodology matters more now than ever.

A Brief History

The T-Group — short for "training group" — was originally developed in the late 1940s at the National Training Laboratories (NTL) in Bethel, Maine. Social psychologist Kurt Lewin and his colleagues discovered something remarkable: when people gathered in small groups and paid close attention to their real-time interactions, something shifted. People started to see themselves more clearly. They began to understand how they affected others — and how others affected them.

Stanford Graduate School of Business adopted and refined this methodology into what became the Interpersonal Dynamics course, affectionately known by students as "Touchy Feely." Over the decades, it evolved into one of the most sought-after courses at Stanford, with a long waitlist every year. Faculty like David Bradford and Carole Robin built the course into a rigorous, deeply researched approach to developing interpersonal effectiveness.

What is interesting is that this is not therapy, and it is not team-building in the way most people think of it. It is something altogether different.

So What Actually Happens in the Room?

Imagine sitting in a circle with eight to twelve people. There is a facilitator present, but there is no agenda, no slide deck, no predetermined topic. The only instruction is this: pay attention to what is happening in this group, right now, between us — and talk about it honestly.

That is it. And that simplicity is precisely what makes it so powerful.

Without an agenda to hide behind, people start showing up as they actually are. The person who always takes charge begins to notice they do it here too — and starts to wonder why. The person who stays quiet realizes that their silence is not neutral; it has an effect on the room. The person who makes everything into a joke begins to see what they might be avoiding.

The facilitator's role is not to lecture or direct. It is to create conditions of safety and to gently invite the group to notice patterns as they emerge. When someone says something that lands differently than they intended, that becomes a moment of learning. When the group avoids a difficult topic, the facilitator might name that avoidance — and invite curiosity about it.

"The Leadership Circle creates a laboratory for human interaction. Dynamics that play out in your career surface in the room. But unlike real life, you get real-time feedback."

What Participants Experience

For many of the leaders we work with, the first hours of a T-Group feel unfamiliar. Some feel impatient — where is the content? Some feel anxious — what am I supposed to do? Some try to take over. Some withdraw. All of these responses are useful information.

What tends to happen, gradually and then suddenly, is that people begin to take real interpersonal risks. Someone shares that they felt dismissed by a comment made an hour ago. Someone else admits they have been holding back because they are afraid of being judged. A third person says, honestly, that they noticed they were trying to impress the group rather than be genuine.

These moments are where the learning lives. Not in the abstract, not in a case study about someone else's company, but right here, between real people, in real time. When a leader hears from three different people that they come across as warm but distant — that they share ideas but rarely share themselves — it lands differently than any 360 review ever could.

We have seen leaders come into the Circle certain they were great listeners, only to discover that what they thought was listening was actually waiting to speak. We have seen leaders who believed they were approachable learn that their intensity kept people at a careful distance. These are not failings. They are blind spots that become visible in the T-Group — and once you can see them, you can choose what to do about them.

Why It Works for Leaders

Most leadership development focuses on what to do. Read this framework. Follow this process. Implement this system. The T-Group works differently. It focuses on who you are when you are in relationship with others — and that is where leadership actually lives.

The leaders who have the deepest impact are not the ones with the best strategy decks. They are the ones who can sit with discomfort, who can hear hard truths without becoming defensive, who can be honest without being harsh, who can be vulnerable without losing their authority. These are not skills you can learn from a textbook. They are capacities that develop through practice, in relationship, with other people.

What is interesting is that the effects tend to show up quickly in real life. Leaders return to their teams and notice things they did not notice before. They hear the unspoken tensions in a meeting. They catch themselves falling into old patterns — and they pause, and they choose differently. Their teams notice the shift, even if they cannot name it.

How We Bring This to Leaders in Vietnam and Southeast Asia

At Green Tara Leadership, our Influential Leadership Circle is built on this same T-Group foundation, adapted for the specific context of leaders working in Vietnam and across Southeast Asia. Our founder, Tara Hill, trained in this methodology at Stanford and has spent years understanding how to create the conditions for deep interpersonal learning in a cross-cultural environment.

Our Circles are deliberately small and carefully curated. We bring together senior leaders from diverse industries who share a genuine desire to grow — not just professionally, but as the humans who show up to lead every day. The experience unfolds over four days: three days of immersive Circle work, followed by an integration workshop where participants reflect on what they have applied and build practical frameworks for continuing the work in their teams and organizations.

We have found that leaders in this region are hungry for this kind of depth. Many have done the executive education programs, the MBA courses, the leadership retreats with their icebreakers and personality assessments. What they have not had is a space where they can be truly seen — and where they can practice being truly honest — with a group of peers who are doing the same.

That is what the T-Group offers. Not answers, but a kind of awareness that makes better answers possible.
