Diversity in a team doesn't manage itself

Diversity in a team does not manage itself. I will start with a confession I hear from leaders surprisingly often: "I know diversity is important. I just don't know what to actually do with it." This is a very honest perspective for me, because over the last decade, organizations have invested huge amounts of money in training on unconscious bias, inclusivity, and inclusion. Yet, daily life shows that the same people continue to speak up, the same profiles get promoted, and new voices, if they appear at all, quickly adapt to the existing rules and often fall silent. The problem does not lie in bad intentions. It lies in the fact that diversity has been sold to us as a state that is enough to achieve. Meanwhile, it is a practice that requires a leader who knows what to do and why.

Diversity without management is a recipe for friction, not innovation.

There is one study I like to cite because it brutally verifies popular beliefs. Katherine Phillips from Columbia Business School showed that diverse teams achieve better results, but only when they actively engage with the perspectives of others. It is not enough to have different people sitting in a room. What matters is whether the leader can activate these differences and engage them appropriately (How Diversity Makes Us Smarter, 2014).

David Rock and Heidi Grant went a step further and checked what blocks this mechanism. It is primarily a lack of psychological safety—if people do not feel they can disagree, they nod along loudly, but in reality, they disagree. In such an environment, diversity does not generate better decisions. It generates better-faked agreement (Why Diverse Teams are Smarter, 2016).

This is the moment where most DEI programs stop. And it should only be the starting point for a leader.

The hardest part is starting with yourself.

There is no diversity management without working on your own thinking. It is uncomfortable, but true. Mahzarin Banaji and Anthony Greenwald—psychologists who have studied unconscious bias for years—showed in their book "Blindspot: Hidden biases of good people" that cognitive patterns work in everyone, regardless of how convinced someone is of their own impartiality. A leader listens more carefully to people who think like them, assigns credit to those they like, and assesses risk differently depending on who presents it. That is how the human brain works under time pressure and information overload. The problem arises when a leader pretends this does not apply to them.

For a leader, it is crucial to regularly check: whose ideas are they developing and whose are they ignoring? Who are they inviting to meetings, who are they including in projects, and who are they overlooking?

Psychological safety—a boring name, a crucial thing.

Amy Edmondson from Harvard Business School has spent decades studying what makes diverse teams truly work. And she kept returning to one answer—psychological safety, which is the conviction that I can speak up without the risk of being ridiculed, ignored, or punished.

A leader cannot command this, but they can build it in a team through how they react when someone makes a mistake, whether they admit to their own mistakes, whether they ask for the opinions of people who normally stay silent during meetings, or whether they always start with their own opinion, closing the discussion before it has even begun. It is worth reaching for the book "The Fearless Organization" by the same researcher to see what seemingly minor details determine whether diversity in a team is an asset or just a hollow shell.

The hard side—what’s in it for the company.

You can believe in diversity because it’s the right thing to do. You can also simply look at the data. McKinsey studied over a thousand companies in fifteen countries and found that those with higher gender and ethnic diversity are 25% and 36% more likely, respectively, to have above-average financial performance (Diversity Wins. How inclusion matters, 2020). This is no magic, just simple facts: diverse teams consider more options, catch more errors, and better understand diverse customers.

On top of that, there is retention. Deloitte showed that for Millennials and Gen Z, an inclusive culture is one of the key reasons why they stay at or leave a company (The Deloitte Global Millennial Survey, 2020). The cost of losing an employee—counting recruitment, onboarding, and lost know-how—is, according to various estimates, between half and double their annual salary. That is why diversity that a leader consciously manages simply pays off.

If the topic of diversity is to go beyond slides and be a daily element of how a company functions, it requires action on three levels. The first is leader awareness, which means working on your own way of thinking, understanding the mechanisms of exclusion, and the ability to see what is happening in the team beneath the surface. The second is behavior, which means concrete and visible daily practices, e.g., how meetings are conducted so that the same people do not constantly dominate, giving feedback that is truly objective and based on facts, and asking questions to hear rather than just confirm your own thoughts and beliefs. The third level is the system, which is the broader context in which the leader operates. Here, it is worth looking at processes or policies to see if they are designed for homogeneity. Iris Bohnet from Harvard showed that structural changes, including in recruitment or evaluation processes, have a greater impact on inclusion and diversity than any training (What Works: Gender Equality by Design, 2016). When a leader is aware of these levels, it is much easier for them to exert influence and change the work environment.

Diversity is not a project to be completed. It is an environment that is constantly built through daily practices and behaviors. Leaders who understand this stop asking "do we have a diverse enough team" and instead check "can my people be themselves here?" The latter question is harder because it requires courage and openness, and above all, a readiness to take the right actions to not only retain talent in the organization but to fully utilize their potential and diversity.
