Why Brilliant Teams Still Underperform
You can hire A-players. You can coach them, assess them, develop them and pay them well. You can still end up with a team that underperforms, where ten brilliant people somehow add up to less than five.
I have watched this pattern for more than two decades. The cause is rarely talent. It is team cohesion: the connection and alignment that live between people, the part of workplace culture almost no one measures.
Most organizations invest heavily in the individual. Personality assessments. Executive coaching. Individual performance metrics. All useful. None of them tell you how people actually work together.
The team is more than the sum of its parts.
The research has been pointing here for years. In 2010, Anita Woolley, Thomas Malone and colleagues published a study in Science showing that groups have a measurable “collective intelligence.” It was not strongly correlated with the average intelligence of the members, or with the intelligence of the smartest person in the room. What predicted it was how people interacted: their social sensitivity and how evenly they shared the conversation.
Google found something similar when it studied 180 of its own teams in Project Aristotle. Its conclusion was blunt: who is on a team matters less than how the team members interact, structure their work and view their contributions. The strongest dynamic of all was psychological safety.
Dr. Bobbi Wegner, a health psychologist, Harvard lecturer and founder of Groops, puts it in a single image. A team is like vines climbing a wall. Once they intertwine, they grow into something different from any single vine. Her team has measured these dynamics across more than 1,200 people in 39 organizations, and her conclusion matches mine: the team is its own being, and we keep studying the parts.
In our own research on what helps people and organizations thrive, most of the drivers sit at the team and job level, not inside the individual. A mental health app cannot fix a team where people do not feel they belong.
What is team cohesion? Connection plus alignment
I find it useful to think of team cohesion as two dials.
Connection is the human layer. Do we know each other beyond our titles? Do we feel seen? Can we laugh together? On the most connected teams I work with, I see humor, play and joy. People know each other’s origin stories.
Alignment is the work layer. Do we share clear goals? Do we know what each person brings and where our roles begin and end?
When the dials are out of balance, teams fail in predictable ways.
When connection is high but alignment is low, the team feels like a group of friends. Everyone gets along. The friction comes from somewhere else: no one is clear on the goal, the direction, or who owns what. Liking each other isn’t the same as knowing where you’re going.
The opposite pattern, high alignment with low connection, is far more common. The KPIs are clear. Meetings open with “let’s jump into business.” No one asks how anyone’s week has been and it works for a while, but then it becomes a retention problem. A paycheck might keep people for a while, but relationships are what keep them for the long term.
What keeps a team together through the hard moments is what Bobbi calls a tether. Every relationship moves through rupture and repair. When I inevitably say something that frustrates you, cohesion is the reason you stay in the conversation instead of walking away.
Agreement is not alignment: groupthink and psychological safety at work
One of the clearest warning signs is a team that never disagrees. Leaders often read that as health, but it is usually the opposite.
Agreement is not the same as alignment.”
Almost no group of humans is ever fully on the same page. When a team shows no friction at all, the likelier explanation is groupthink: people do not feel safe enough to speak up. Psychological safety at work is not a soft topic, it is where big ideas get put on the table and where a bad interaction gets named and fixed before it slows everything down.
Bobbi frames conflict as exercise:
Conflict and disagreement is us exercising that muscle that is actually actively building trust.”
I can push, and you are still here. You can push back, and I am still here. That is what belonging feels like in practice.
The other signs are quieter – rising churn, engagement scores that slip, a team that hits its numbers but does not feel good, which usually means it is sub-optimized rather than failing, and nobody can quite say why.
Where team dynamics really live: the space between
Bobbi borrows a practice from how therapists are trained. When a feeling shows up in a conversation, say a flicker of tension, she separates it out and asks three questions. 1) Is this mine, coming from my own thought patterns? 2) Is it yours, something I am picking up from you? 3) Or is it something about our intersection?
Most of us never ask. We have an awkward exchange, assume it is the other person (or ourselves), and quietly hope it does not happen again. The issue goes underground and, over time, it becomes the reason that a good person leaves.
She shared a story from a globally distributed product team at GE Power. One top performer, based in Europe, was close to leaving. It was not pay or workload. She had stopped taking her long lunches with friends, a deep part of her culture, because she assumed her American-led team would see it as slacking. Once she said it out loud, it became a non-issue, however. She stayed at GE Power and the team’s sense of belonging and connectedness rose by roughly 20 to 30 percent.
When I heard that, I recognized the pattern immediately. It wasn’t a compensation problem, it wasn’t a competence problem and it wasn’t a workload problem. It was an unspoken norm about how we are together.
All these dynamics are sitting in the room, whether you talk about it or not.”
The work of a human-centered leader is to make the implicit explicit, then negotiate. What does the team need? What does the person need? Where can we meet?
AI in the workplace is speeding us up and pulling us apart
There is a new force pulling on team cohesion – AI. It lets one person do the work of five or six, faster. I feel this in my own company. The risk is that we gain speed and lose what made the team worth having: thinking together, challenging each other, building ownership and creating meaning together.
Bobbi lived this. She spent six months using AI to reposition her company’s mission, vision and values, staying up late, feeling she was moving the needle. Then she felt the energy on her team change. Her COO told her directly that she was going off into an AI world and leaving everyone behind, and that it was killing motivation.
Here is the recommended fix they made – one person does the AI pre-work: consolidating data, drafting options, getting to a strong first version. Then the team comes together to problem solve and decide. Speed and discussion are preserved and Bobbi’s COO’s reaction said it all – once her voice was heard, she was okay with wherever they landed.
The research suggests this is not a startup quirk. A 2023 study in the Journal of Applied Psychology, led by Pok Man Tang, followed employees across the United States, Taiwan, Indonesia and Malaysia. Those who worked more with AI systems reported more loneliness, which spilled into insomnia and after-work drinking.
So the question I keep asking myself, and asked Bobbi, is this:
Are we actually at a risk of optimizing efficiency and accidentally destroying commitment?”
AI can still be a co-creator. I use AI personas of the leaders we serve to pressure-test ideas. It works best as a co-intelligence that prepares the ground, not as a replacement for the people who have to own the outcome.
How to build team cohesion: three practices to try
None of these practices take more than a few minutes.
- Open with a highlight or a lowlight. Ask each person to share a highlight or lowlight from the past week, personal or professional, in 10 to 20 seconds. If a colleague shared that their child was sick all weekend, you’ll understand why they seem short-tempered and, instead of assuming the worst, you can offer to help..
- Ask the zero-to-ten question. “From zero to ten, how connected is this team right now?.” Then ask what would move it one notch higher and one notch lower. Do not aim for ten. Aim for the next half point. Pick one action together and ask again next month.
- Replace advice with “what” and “how.” Before you jump in with a solution, ask an open question that starts with what or how, and notice what you learn. It is the core of motivational interviewing, the coaching approach Bobbi teaches at Harvard. People rarely change because we push them. They change when we help them hear their own reasons.
Teams can be the best part of the job
Social relationships are one of the strongest predictors of how long and how well we live.
We spend most of our waking adult hours at work so that makes the team one of the most important relationships in a person’s life.
Kahlil Gibran in The Prophet says work is love made visible. I think for most people, they would say work is hate made visible.”
It does not have to be that way. One of Bobbi’s clients, a senior leader at a fintech company, saw team coaching on his calendar and was sure it would be a waste of time. Halfway through the program, he told the group that what he was learning had improved his relationships with his wife and his daughter too. That is what happens when we build cohesion on purpose; the team gets better, and so do the people in it.
