Optimal Diversity™
Observable diversity, coupled with intentional diversity of thought.
“Diversity is the art of thinking independently together.”
— Malcolm Forbes
What Optimal Diversity™ Means
Optimal Diversity™ builds on observable diversity by additionally ensuring that diversity of thought is present.
The word that carries that sentence is additionally. Optimal Diversity™ is not a choice between who sits in the room and how the room thinks. It is both. Observable diversity, the difference you can see in background, experience, gender, ethnicity, and age, is the foundation, and it is fully honored here. Diversity of thought, or cognitive diversity, is what you build on top of it, on purpose.
That second part is the work. Most people assume a board that looks diverse automatically thinks diversely, and often it does. Not always. A room can be observably diverse and still share a single way of seeing the world, when the people in it were shaped by the same forces. Cognitive diversity does not arrive for free. It has to be intentional.
This is why Optimal Diversity™ asks two questions at once, through two lenses:
As a board: are we built to represent our shareholders and the broader community we serve, and to think differently?
As an individual: what do I bring that no one else in the room can?
The rest of this page works through both.
Why This Raises the Bar
There is a worry that pursuing diversity means lowering the standard. It rests on a false choice, and Optimal Diversity™ dissolves it.
Start with something easy to forget: talent is distributed across every segment of the population. No group holds a monopoly on capability. If that is true, then a search that only looks in familiar places is not the more rigorous one. It is the less rigorous one, because it quietly overlooks qualified people who happen to sit outside the usual networks.
The most meritocratic board, then, is the one that looks the widest. Diversity done well is not a concession to merit. It is merit, pursued thoroughly. The two were never rivals. They are symbiotic.
What gives the false choice its life is tokenism: choosing someone solely for how they look rather than for the human capital and perspective they bring. That is the failure mode of superficial efforts, a quota met, a single training held, a seat filled for appearance. It produces the very outcome critics fear, and it shortchanges the person in the seat. No one wants to be a token.
Optimal Diversity™ asks the opposite question. Not whether a candidate checks a box, but what differing perspective that candidate brings that the board needs and does not already have. That is a standard of merit. It raises the bar. It does not lower.
What You Can See, and What You Can’t
Start by giving observable diversity its due. A board that is observably diverse is already stronger than a homogeneous one. Different identities carry different lived experiences, and lived experience shapes perspective. Two people can pass through the same school and the same firm and still read a problem differently, because who they are shaped what they noticed along the way. That gain is real, and Optimal Diversity™ keeps every bit of it. The only question is whether a board stops there or builds further.
The traits we can see sit on a spectrum of how observable they are. Role, industry, alma mater, gender, ethnicity, and age sit near the visible end. The community that shaped someone, the hardships they moved through, their values and basic assumptions sit near the invisible end. And the attributes that are easiest to see are not the ones that most shape how a person thinks. The ones that most shape thinking are the hardest to see.
Each of us carries what the Princeton psychologist Philip Johnson-Laird called a mental model, a simplified, personal picture of how the world works. Every mental model is useful, and every one is limited. A board thinks best when those models complement one another, and it leaves value on the table when they overlap more than they need to.
Picture a board that is observably diverse in every visible way. Different roles, different ages, women and men, several ethnicities. It is already ahead of a homogeneous board, and its members do bring differing perspectives. Now look at what the photograph cannot show. Every member grew up in the same kind of affluent neighborhood, earned an undergraduate degree and an MBA from the same short list of universities, and began at the same major consulting firms before moving into the Fortune 500.
Those shared beginnings do not erase the differences among them, but they do narrow them. Formed by many of the same forces, the members are more likely to share blind spots, to find the same things obvious and the same things invisible. This board is good. It is simply not yet as strong as it could be, because the range of thinking in the room is narrower than the range of people in the room suggests.
That gap, between how diverse a board looks and how widely it actually thinks, is what Optimal Diversity™ goes after. Not by trading away observable diversity, but by adding to it on purpose: asking which formative experiences and ways of thinking are already in the room, and which the board still needs.
What Changes in the Room
A board with optimal diversity does not just look different. It decides differently, and the difference shows up where it matters most.
Better decisions, fewer blind spots. When directors hold complementary mental models, the board is less prone to groupthink. Someone tends to see what the others would have missed, so assumptions get tested before they harden into decisions.
A sharper read on risk. Different formative experiences sense different dangers coming. Where a board’s experience overlaps, its blind spots overlap too, and those shared gaps are exactly where risk and missed opportunity hide.
Range to match the complexity. No single director can stay expert across cybersecurity, geopolitics, shifting markets, and a moving regulatory line. A board of differing perspectives covers more of that ground, and covers it earlier.
An advantage that is hard to copy. A competitor can hire away a strategy or match a product. It cannot easily replicate how a board thinks. Optimal Diversity™ becomes embedded in the way decisions are made and challenged, which is what makes it durable.
None of this is automatic, which is the entire point of the framework. A board earns these results; it does not inherit them. It earns the better decisions, the sharper read on risk, the range to meet real complexity, and the advantage no competitor can copy. It earns them by looking wider than its usual networks for the people who bring them, and by building the diversity of thought a wider table makes possible. That is Optimal Diversity™, and that is the difference.
The Other Lens: What You Bring
Optimal Diversity™ is not only something a board builds. It is something you bring.
Everything so far has looked through the board’s lens. Turn the framework around and it asks a question of you: what differing perspective do you bring that the room does not already have?
This is where the framework includes everyone. The perspective you bring comes from how you were formed, not from a box you can be sorted into, and no two people were formed the same way. Your formative experiences, the places that shaped you, the obstacles you moved through, the way you learned to read a problem, are yours alone, and most of them sit at the invisible end of the spectrum, where the perspective that actually changes a conversation lives. The work is to know what yours are, and to say them in a way a board can understand and use.
People are often chosen, or overlooked, for how they look: gender, race, age, and the rest. Optimal Diversity™ asks you to do something within your control instead: take the time to reflect on and learn your differentiators, then shape them into a clear value proposition for the boards you want to serve. It is a process anyone can work through, whatever their gender, ethnicity, or age. That is why meritocracy and diversity can coexist: everyone is asked to do the same work, and to earn the seat on the strength of what only they bring.
For most accomplished leaders, the gap is not the perspective. It is the language. You have the experience; you have not yet connected the dots and translated it into the differentiated value a nominating and governance committee can recognize. That translation is learnable, and it is much of the work I do with the executives I coach.
What the Research Taught Me
I did not arrive at Optimal Diversity™ from theory. I arrived at it from listening.
I have formally and informally interviewed hundreds of independent directors who made the transition from the executive suite to the boardroom, many of them women. I wanted to understand what actually got them seen and chosen. The pattern held: the leaders who earned the seat were the ones who understood their own differentiating perspective and could connect the dots between it and the value a board needed. Optimal Diversity™ is what I built from that pattern, for the board constructing the room, and for the leader working to enter it.

Common Questions
What is Optimal Diversity™?
Optimal Diversity™ builds on observable diversity, the differences you can see in background, experience, gender, ethnicity, and age, by additionally ensuring diversity of thought: the complementary mental models and differing perspectives that shape how a board actually thinks, decides, and challenges. It is a both/and, not a trade-off. Observable diversity is the foundation, and intentional cognitive diversity is what you build on top of it, on purpose.
Does pursuing board diversity mean lowering the bar?
No. Talent is distributed across every segment of the population, so the board that searches the widest is the most rigorous, not the least. Optimal Diversity™ asks what differing perspective a candidate brings that the board needs and does not already have. That is a standard of merit. It raises the bar; it does not lower it.
Can meritocracy and diversity coexist?
Yes. Each person brings their human capital, the sum of their education, knowledge, skills, and experience, along with the differing perspective only they can offer. Optimal Diversity™ asks everyone to do the same work: surface both, and shape them into a clear value proposition for the boards they want to serve. A process that asks the same of everyone, whatever their gender, ethnicity, or age, is not a thumb on the scale for anyone. The seat is earned on the strength of what you bring. Meritocracy and diversity can coexist.
Optimal Diversity™ is built on purpose, by the board that seeks it, and by the leader who earns a place in it.
