Title: The mother-in-law test
Subtitle: Self-authoring as a Korean American
Introduction
Asian Americans are among the most credentialed and hardest-working professionals in the United States and among the most underrepresented in senior leadership. This book argues that the gap between those two facts is not a pipeline problem or a discrimination problem alone. It is a developmental one. The same cultural forces that make Asian Americans exceptional early in their careers - filial piety, deference to hierarchy, group-based thinking - gradually disconnect them from the internal compass that effective leadership requires. Drawing on Robert Kegan's adult development theory, two decades of cross-cultural professional experience, and hundreds of coaching conversations with Asian American executives, The Mother-in-Law Test offers the first framework of its kind: one that takes the cultural roots of that disconnection seriously, traces them honestly through real lives, and charts a practical path toward leading from within.
What this book is about
In Korea, there is an informal test that shapes some of the most consequential decisions a person makes. No one administers it. There is no rubric, no score, no official moment when it is applied. And yet almost everyone applies it, often without knowing they are doing so. The question is simple: would my future mother-in-law approve?
Which university did you attend? Which company do you work for? What is your salary, your title, your family background? The mother-in-law test is shorthand for something much larger than marriage — it is the constant, invisible tribunal of social approval that governs how Korean families evaluate a life. And what makes it so powerful is not that people are forced to submit to it. It is that, after enough repetition, they stop noticing they are.
I grew up inside that tribunal. My father worked at Samsung Electronics for over forty years, and when I was applying to college, it never occurred to me to want something different. I wrote in my MBA application that my ambition was to become CFO of the company. Looking back, it was simply the most legible version of success available to me, the one that would pass every test I knew how to take. Most of the Asian American executives I now coach would recognize that feeling exactly.
What I have come to understand through my own career, through hundreds of hours of coaching conversations, and through the slow uncomfortable work of my own adult development is that the mother-in-law test does not stay in Korea. It travels. It shapeshifts. It shows up in the American professional who cannot say no to a project that doesn't serve them, in the executive who knows exactly what they want to say in the meeting but waits to see which way the room is leaning first, in the high achiever who has spent twenty years succeeding at goals they never actually chose. The tribunal relocates. It just finds new judges.
This book is about learning to recognize the tribunal and then, carefully and without bitterness, choosing which of its verdicts to keep and which to finally set down.
Core frameworks
At the heart of sustainable leadership is a concept I refer to as self-authoring. Whether we borrow this term from adult development theory, Robert Kegan's work on the evolving self, or trace it back through the Transcendentalists, the core truth remains the same: to lead effectively and sustainably, you must possess a strong internal compass and understand the conformity you are breaking from. You have to know who you are and what you stand for.
For many Asian Americans, this leap to a self-authored mind is uniquely difficult — and the same cultural forces that make it difficult are precisely what drove our early success. We are exceptional at reading the room, honoring expectations, and working relentlessly toward the metrics of success defined by others. In school and early career, that engine is powerful. But eventually, it stalls. The very forces that propelled us forward have profoundly disconnected us from who we actually are.
This disconnection shows up first as surface patterns: the need to be the best at everything, a reliance on individual expertise rather than relationships, or a quiet endurance of roles that no longer fit. Beneath them lie the driving patterns — the painful reality of not knowing what you actually want, or struggling to act on your own will once you do figure it out. And at the root sit three cultural forces I call the clouds: the importance of filial piety, deference to hierarchy, and group-based thinking, all intensified by the pressure of rapid growth and high expectations.
Moving forward requires a different kind of work. I guide readers through a continuous four step cycle:
Clarity: Honestly identifying the cultural clouds and surface patterns operating in your life right now.
Discovery: Doing the hard work of unearthing your own authentic values, separating what you actually want from what your family or culture expects of you.
Experiment: Taking small, calculated risks to test your new voice in the real world, whether that means setting a boundary or speaking up in a high-stakes meeting.
Reflect & adjust: Evaluating the outcome of those experiments with self-compassion, learning from the friction, and refining your approach.
Narrative style and approach
This is a book written from the inside out. Rather than offering frameworks from a distance, I place my own lived experience at the center including the missteps, the internal dissonance, the slow and uncomfortable work of my own adult development. My career arc, from the intense hierarchy of Samsung Electronics through executive roles in the US renewable energy sector, provides the primary lens through which the book examines the cultural conditioning that Asian American leaders carry but often without knowing it.
This is not purely memoir though. Each chapter moves between my own story, the anonymized experiences of coaching clients I have worked with closely over many years, and the core framework (see below). Where my story provides the emotional and personal grounding, the client cases show the same dynamics playing out in real time. I hope that this movement between the personal and the observed allows frameworks of cultural clouds, self-authoring, and the road to self-authorship to land as something felt rather than merely understood.
The tone throughout is intimate and direct. I do not write as someone who has resolved these tensions. I write as someone who has learned to see them clearly, and who believes that clarity itself is a form of liberation. Readers will not find polished success stories here. They will find honest accounts of stalling, overcorrecting, and slowly finding a truer footing because that is what the journey actually looks like.
Target audience
Primary audience: Early to mid-career Asian American professionals
The reader I am writing for is someone who has done everything right, excelled in school, landed competitive roles, earned consistent recognition, and yet feels a growing gap between their external achievements and their internal experience. They are succeeding in ways that increasingly feel borrowed rather than their own. They may find it difficult to speak up in certain rooms, to set limits with certain people, or to say clearly what they want when given the chance to choose. They are beginning to feel the cost of a life lived primarily for others' approval and they are ready for a different way of thinking about who they are and how they lead.
This reader exists in large numbers. Asian Americans are the fastest-growing segment of the US professional workforce and are significantly overrepresented at elite universities and in knowledge-economy roles. Yet they remain dramatically underrepresented in senior leadership, a gap that is rarely explained by effort or capability, and almost never addressed honestly in the leadership literature written for them.
Secondary audience: Anyone navigating the passage to self-authoring
While the book is rooted in the Asian American experience, the underlying journey of moving from a life shaped by inherited expectations to one lived from your own values resonates well beyond any single cultural group. Readers from other immigrant communities, multicultural backgrounds, or anyone caught between what they were raised to want and what they actually want will find the framework and the stories directly relevant. The specificity of the Asian American lens, rather than limiting the book's reach, tends to make its themes more vivid and honest, not less universal.
Practitioner and community audience: Coaches, learning communities, and leadership organizations
A meaningful secondary market exists among the practitioners and communities where this conversation is already happening. Executive coaches and therapists working with high-achieving professionals frequently encounter the exact tensions this book addresses and actively seek frameworks and reading they can share with clients. Leadership book clubs, particularly those within Asian American professional networks, are a natural and highly engaged audience. And leadership development organizations, including university programs, alumni networks, and professional associations, regularly bring in speakers and assign reading that addresses cross-cultural identity and leadership effectiveness. My existing relationships across these channels through my coaching practice, my work with the MIT Leadership Center, and my MIT Sloan alumni network give me direct access to these communities as both a reader pipeline and a speaking and workshop platform.
About the author
Joonki Song
I am, in many ways, the subject of this book.
My professional life has spanned two continents and several industries: I began as a soldier in the US Army in Korea, moved into corporate finance at a large Korean conglomerate, earned my MBA at MIT Sloan in 2006, and spent the next decade building renewable energy businesses across the US and Asia including opening and leading a new business unit in Korea for a US company. On paper, this looks like a story of consistent forward momentum. In lived experience, it was something more complicated.
Deference, group thinking, and relentless hard work fueled my early success in ways I did not fully appreciate at the time. Those same forces eventually became the thing holding me back and disconnecting me from who I actually was. Recognizing that tension, and doing the hard work of moving through it, is what ultimately led me to pivot into executive coaching.
Through my coaching practice and my ongoing work with the MIT Leadership Center, I have sat with dozens of Asian American executives and seen my own experience confirmed again and again. We are often extraordinarily accomplished on paper. And yet there is a persistent internal dissonance, a gap between the success we've achieved and the sense that we haven't yet found our own voice inside it. This book is my attempt to name that gap clearly, and to offer a way through it.
My network and platform
My coaching practice at Shimoo, a leadership consultancy, and my work with the MIT Leadership Center place me in regular, substantive conversation with the senior Asian American leaders this book is written for. These are ongoing engagements with executives, founders, and emerging leaders who are actively wrestling with the cultural and professional tensions the book addresses, and who frequently bring these frameworks back into their own organizations.
My professional network spans Korea, China, Japan, Taiwan, Germany, and the United States, built across two decades of working across industries and cultures. To extend these conversations beyond confidential coaching engagements, I am actively building a public writing presence. My articles and evolving frameworks are published at shimoopartners.com/articles, and I recently launched a Substack to reach a broader audience of Asian American professionals seeking exactly this kind of frank, experience-based perspective.
Chapter outline and excerpts
Introduction: The mother-in-law test and the invisible ceiling
In Korea, there is an informal tribunal that governs how families evaluate a life: the mother-in-law test. Through the story of a highly successful friend grappling with this pressure, and through my own transition from Samsung Electronics to executive roles in the United States, I introduce the central friction this book addresses. The reader discovers that their individual workplace struggles are not personal failures but shared, systemic cultural patterns — and that naming them is the first act of moving through them.
Chapter 1: Adult development and the socialized mind
This chapter introduces the psychological foundation of the book through Robert Kegan's adult development theory, specifically the difficult transition from the "socialized mind" to the "self-authored mind." Using anonymized coaching cases, I show why this leap is uniquely hard for Asian Americans — not because of any deficit, but because the cultural forces that shaped our early success were exceptionally effective at socializing us away from our own internal compass.
Chapter 2: The cultural clouds
Here we examine the three forces operating beneath the surface of the behaviors we see in the workplace: filial piety, deference to hierarchy, and group-based thinking. I explore how these traits are genuinely double-edged. They propelled our academic and early career success with extraordinary efficiency. And they have, over time, obscured the internal compass that effective leadership requires. This chapter names the mechanism clearly, without asking the reader to abandon what their culture gave them.
Chapter 3: The surface patterns in the workplace
This chapter moves from deep cultural roots to daily reality, tracing how the clouds manifest as visible friction: the paralyzing need to be the best at everything, the reliance on individual expertise rather than shared trust, the inability to set limits with authority figures. I also introduce a generational matrix, showing how these patterns surface differently for first-generation immigrants, 1.5-generation, and second-generation Asian Americans — a distinction that most leadership literature ignores entirely.
Chapter 4: The road to self-authorship
Drawing on my own journey and the journeys of clients I have coached over many years, I introduce a four-step practice: Clarity (honestly mapping your frustrations back to their cultural roots), Discovery (separating your authentic desires from family expectations), Experiment (taking small, calculated risks to test a new voice), and Reflect and Adjust (evaluating the outcome of those experiments with self-compassion, learning from the friction, and refining your approach). The chapter moves between framework and story throughout.
Chapter 5: The paradoxes of self-authoring
Becoming self-authored is not a clean break from your past. It is a negotiation. This chapter explores the inevitable tension between honoring your family and choosing your own path — and argues that the guilt accompanying that tension is not a sign something is wrong, but a sign something is changing. A trip to Copenhagen becomes the organizing lens: the contrast between the obligatory loyalty woven into many Asian cultures and the concept of chosen loyalty I observed in Denmark offers a way to think about cultural inheritance that is neither rejection nor submission.
Chapter 6: Living the compass with practices
This chapter translates the book's framework into a daily practice. I share specific tools my clients use to sustain their self-authored voice in real conditions: how to set explicit meeting norms that interrupt automatic deference, how to use the "parent interview" to shift family dynamics from a child-parent hierarchy to an adult-adult relationship, and how to recognize the moments when the old operating system is running without your consent. These are not tricks. They are the small, repeated acts that make self-authorship a lived practice rather than a resolved question.
