When Multicultural Teams Struggle, Culture Isn’t the Problem—Unspoken Assumptions Are.
When people on a team come from different cultural backgrounds, it is easy to explain friction by saying, “We just have different ways of communicating.”
That can be true—but it is not the whole story.
Cultural backgrounds can shape how people express disagreement, respond to authority, give feedback, and signal commitment. The problem begins when a team assumes that everyone interprets those moments in the same way.
Consider a project meeting. A leader asks whether the team can meet a new deadline. A few people agree. Others say nothing.
The leader takes the silence as alignment and moves on. A week later, the deadline slips. One person had concerns but did not want to challenge the leader publicly. Another believed the timeline was still open for discussion. A third needed more detail before committing.
No one intended to create friction. They were working from different, unspoken assumptions.
Cultural difference does not cause friction on its own. Friction grows when a team leaves its most important communication rules unspoken.
Research on multicultural teams shows that diversity does not automatically help or hurt performance. Its effects depend on what happens inside the team: conflict, cohesion, creativity, and coordination. Stahl et al., 2010.
This is why intercultural communication is not a “nice to have.” It is the practical skill of making differences discussable before they become misunderstandings.
A leader does not need everyone to communicate in the same way. They need to make space for questions such as:
- What concerns do we need to surface before deciding?
- How will we challenge an idea or a deadline?
- What does commitment mean on this team?
- How do we want feedback to be given?
Cultural intelligence—the ability to work effectively across cultural contexts—has been linked to stronger multicultural-team performance over time. Moon, 2013.
The goal is not uniformity. It is shared clarity.
When teams make their assumptions visible, they create better conditions for feedback, stronger decisions, and more effective collaboration across cultures.
