You Built a Diverse Team. Now Comes the Hard Part.

Most leaders treat building a diverse team as the destination. The research describes it as the start of a much harder design challenge that many teams skip past. A diverse roster doesn’t produce an inclusive climate on its own, and the absence of inclusion shows up in performance metrics within months.

A team gets assembled and the roster looks exactly right. Different backgrounds, different nationalities, different life experiences. Leadership is proud, the leadership team takes a photo, and around the two month mark the team is underperforming. The good ideas go quiet somewhere between the brainstorm and the decision, and nobody can quite figure out why. The reason is almost always the same one. We’ve confused diversity with inclusion, and they are not the same thing.

The friction nobody can quite diagnose

The symptom shows up as communication friction, as conflict that doesn’t quite resolve, or as a team that technically functions but never really clicks. Leaders reach for explanations about personality mismatches or culture fit, and they are not entirely wrong, but they are diagnosing the wrong level. The team has all the ingredients of a high performing group and none of the conditions that let those ingredients combine.

Research by Ashikali and colleagues studying 293 team members across 45 public sector teams found that greater team diversity doesn’t automatically yield an inclusive climate (Ashikali et al., 2020). You can have a fully diverse team and still have people feeling like outsiders in their own meetings. The diversity is structural. The inclusion gets built deliberately, and it isn’t built simply by assembling the right people.

The counterintuitive finding most leadership training skips

A 2021 study by Leroy and colleagues tested this across three studies including 93 teams drawn from multiple organizations (Leroy et al., 2021). They found that when leaders encourage team members to share their unique perspectives and viewpoints without first building a shared belief that those differences are actually valuable, the effect on team cohesion and creativity can be negative. Not neutral. Negative.

You read that correctly. Asking people to show up differently, before the team believes that showing up differently is a good thing, makes the dynamic worse rather than better. The invitation lands on a team that hasn’t been prepared for it, and people learn to give the safe answer instead.

The researchers describe this as a ‘double edged sword.’ What they call ‘harvesting the benefits of diversity,’ meaning encouraging people to express their unique viewpoints, only produces positive outcomes when leaders have also cultivated what they call ‘value in diversity beliefs.’ The team has to genuinely believe that the differences among them are an asset, rather than a talking point on a slide deck.

When leaders push for diverse viewpoints without first cultivating a team belief that those differences are genuinely valuable, the effect on team cohesion and creativity is negative, not neutral. (Leroy et al., 2021)

What ‘inclusive leadership’ actually does

The term gets used constantly and usually means something vague like making people feel welcome. The research is more precise about the mechanism. Mitchell and colleagues studied 346 members across 75 interprofessional teams and found that leader inclusiveness works through two specific pathways (Mitchell et al., 2015). The first is increasing shared team identity, meaning members start to think of themselves as a collective rather than as individuals who happen to share a calendar. The second is reducing perceived status differences, which matters enormously in diverse teams where hierarchy and credentials can create invisible barriers between people.

The detail most useful in practice: the status reduction pathway was stronger in teams with higher professional diversity. The more different people are from each other in background and credentials, the more that leadership behavior around status signals actually moves the performance needle. Lead a highly diverse team and ignore status dynamics, and you are leaving meaningful performance on the table.

Where the leverage lives

Map who speaks and who doesn’t before your next team meeting, more as a diagnostic than as surveillance. In diverse teams, the people who stay quiet in group settings often have the most contextual knowledge about the problems you’re trying to solve. A 2025 study of 54 ethnically diverse teams found that knowledge sharing had the strongest single impact on team performance of all variables measured (Kanya et al., 2025). The bottleneck is rarely motivation. The bottleneck is psychological safety.

Make the case for diversity before you ask for it. Before your next team session where you want people to bring different perspectives, explicitly name why different perspectives matter for this specific problem. “We’ve always approached this the same way and I want to know what someone coming from a completely different context would notice that we’re missing.” That framing is the difference between harvesting diversity and actually benefiting from it.

Reverse the speaking order. When the most senior person speaks first, everyone else in the room calibrates to that answer. The pattern is human and predictable, and it kills the value of having a diverse team in the meeting. Ask the newest team member to share first. Ask the person with the least institutional tenure what they would change. The behavior directly addresses the status dynamic that the research identifies as a key performance pathway in diverse teams.

Have the one on one conversations you keep postponing. Skip the performance review framing and ask how someone actually experiences working on this team. What they notice that doesn’t get said. What they would change if they could. You will learn more in thirty minutes than six months of team meetings will surface, and that information becomes the foundation for building the ‘value in diversity’ beliefs the research says you need before the bigger invitation can land well.

What sticks with me

I keep returning to the Leroy et al. finding because it challenges something that feels intuitively right but isn’t. When trying to lead more inclusively, most of us focus on the invitation. We create the space. We signal that all voices are welcome. We say it in the all hands and mean it.

If the underlying team belief is that ‘different’ means ‘slower’ or ‘more complicated’ or just harder to work with, the invitation falls on soil that won’t grow anything. You planted something. The conditions weren’t there yet.

What’s the most significant status signal you’ve noticed inside a team you lead or work on?

If this is something you’re working through right now, this is exactly what we dig into in our team workshops at Peak Potential. Or reach out directly and we’ll work through what you’re seeing.

Frequently Asked Questions

Q: What’s the difference between a diverse team and an inclusive team?

Diversity describes who’s in the room. Inclusion describes whether those different perspectives actually get heard, valued, and used in real decisions. Ashikali et al. (2020) studied 293 team members across 45 public sector teams and found that greater diversity doesn’t automatically create an inclusive climate. The two are related but distinct, and you can have one without the other.

Q: Can pushing for diverse viewpoints actually hurt a team?

It can, if the ground isn’t prepared. Leroy et al. (2021) found across 93 teams that encouraging unique perspectives before the team has developed ‘value in diversity beliefs’ can produce negative effects on cohesion and creativity. The invitation needs a foundation before it can land well.

Q: What does inclusive leadership actually do, mechanically?

It works through two specific pathways identified by Mitchell et al. (2015) in a study of 346 members across 75 interprofessional teams. First, it builds a shared team identity so members see themselves as a collective. Second, it reduces perceived status differences, which matters even more in teams with high professional diversity.

Q: How much does knowledge sharing matter for diverse team performance?

More than almost anything else. Kanya et al. (2025) studied 54 ethnically diverse teams and found that knowledge sharing had the strongest single impact on team performance of all the variables they measured. The pathway to better performance in a diverse team runs through whether people feel safe enough to share what they actually know.
