Everyone You Promote
Reminds You of You.

You have one team lead role to fill. You have two strong candidates.

The first candidate speaks up in every meeting. Their English is fluent and fast. When a project goes well, they tell you what they did. They have asked you twice about the next step in their career.

The second candidate speaks less in meetings. When they do speak, it is often to add a point that everyone else missed. Colleagues go to them when they are stuck. When a project goes well, they talk about what the team did. They have never asked you about promotion.

You give the role to the first candidate. It feels like an easy decision. The first candidate looks like a leader.

Eight months later, the second candidate resigns. Two people ask to move to other teams. The new team lead works long hours, and the team’s results have dropped.

The problem was not the choice of one person. The problem was how you saw both of them.

What promotion bias in multicultural teams looks like

Most managers believe they promote on merit. Most of them try hard to. But in a multicultural team, three things make some people much easier to see than others. None of them is leadership ability.

1. Similarity

We judge people more favourably when they remind us of ourselves. This is called affinity bias. The psychologist Donn Byrne showed that people feel more positive towards others who share their attitudes. The sociologist Rosabeth Moss Kanter found that managers tend to promote people who resemble them, because those people feel easier to trust and to predict. Lauren Rivera found the same pattern in hiring at elite professional firms. Interviewers often chose the candidates who shared their own interests and style.

Affinity bias in promotions is not a sign of a bad manager. It is a normal human habit. That is why it needs a process, not good intentions.

2. Fluency

In most international companies, English is the working language. People who speak it with ease sound more confident. Confidence is easy to mistake for ability.

Tsedal Neeley studied this in global companies. She found that employees who were less fluent in the company language often felt a loss of status, even when their expertise was high. Many of them spoke less in meetings as a result. Their managers then saw them as less engaged.

So the manager sees less from the person, and reads that as less ability. The person sees the manager’s reaction, and speaks even less.

3. Different rules for showing good work

People learn different rules about how to show that they are good at their job.

In more individualist work cultures, you talk about your own results. You say “I”. You ask for the next role when you feel ready.

In more collectivist work cultures, you give credit to the group. You say “we”. Talking about your own success can feel like boasting.

In work cultures with higher power distance, you wait for your manager to notice your work and offer you the role. Asking for promotion can feel disrespectful to the person above you.

A manager who learned the first set of rules reads the first candidate as ambitious. They read the second candidate as happy where they are. Both readings can be wrong.

Are your high performers overlooked?

Look again at the second candidate. Colleagues trust them. They notice what others miss. They make the team’s work better and they share the credit. These are leadership qualities. They are simply quiet ones, and they do not show up in a meeting.

Research on leadership styles across cultures, including the large GLOBE study, shows that people in different cultures expect different things from a good leader. Some expect a leader who is visible and decisive. Others expect a leader who listens, builds agreement and protects the group. A multicultural team contains both sets of expectations. It needs a leader who can work with all of them.

The person who already works well across these differences may be the person you did not choose. This is how high performers are overlooked in international teams. Nobody decides to ignore them. The process simply never looks in the right place.

This connects closely to the silence trap: the quiet people in your meetings are often not the least valuable people on your team.

What promotion bias costs you

The cost is rarely visible on the day you decide. It appears over the following year.

The person you passed over often leaves. We looked at this pattern in why your best regional hire leaves sooner than you think. Replacing them means months of recruitment, and then more months before the new person knows the work. The team also loses the person others went to for help. Those questions now come to you.

The person you promoted may need extra support, because part of the team does not respond to their style. That support takes your time.

Over several rounds of promotion, the cost grows. Your managers start to look and sound the same. You lose people who understand local customers and local colleagues in ways head office does not. We saw what happens then in the local team knew the deal would not work.

If you are responsible for HR, L&D or a country, treat promotion bias in multicultural teams as a pattern, not as a single decision. Your succession plan shows the habits of the people who choose. It may not show the talent you have.

How to reduce affinity bias in promotions

You do not need to change who you are. You need to change how you decide. These six steps work in teams of any size.

1. Define the role before you look at people.
Write down what the role needs in the next two years. Be specific. “Strong communicator” is not enough. Write “keeps a team of eight with three working languages aligned on priorities”. Then judge each candidate against that list.

2. Collect evidence from outside meetings.
Meetings reward fast, fluent speakers. Look at delivery records, written work and project outcomes. Ask: who do colleagues go to when they are stuck? That person is often already leading.

3. Separate language from ability.
When you assess a person, ask what they said, not how they said it. Give candidates a chance to share ideas in writing as well as in speech. Some people show their thinking much better on paper.

4. Ask about ambition directly and privately.
Some people will never put themselves forward. In their experience, that is not how it is done. So ask them. “Are you interested in leading a team? What would you need to feel ready?” One private conversation can change your whole shortlist.

5. Look at your last five promotions.
What do the people have in common? Language, background, style in meetings, the way they talk about their work? If the answer is “a lot”, the pattern is telling you something.

6. Bring in a second view.
Ask someone who works differently from you to join the decision. Ask them what they see in each candidate. You will notice different things.

Questions leaders ask about promotion bias

What is promotion bias in multicultural teams?

It is the tendency to promote people whose way of working feels familiar to the person deciding. In multicultural teams, it usually favours fluent speakers of the working language and people who talk openly about their own results. It overlooks people from backgrounds where modesty, group credit or waiting to be asked are the norm.

Why are high performers overlooked in international teams?

Because many promotion decisions rely on what managers see in meetings. Strong performers who are less fluent, more modest or more deferential to authority show less of their work in meetings. Their value is real, but it is less visible.

How do you reduce affinity bias in promotions?

Define the role’s needs before you consider candidates. Collect evidence from delivery and peer input, not only from meetings. Ask quieter team members directly about their ambitions. Review the pattern across your recent promotions, and include a second person in the decision.

Is fluent English a fair measure of leadership potential?

No. Fluency in the working language affects how confident someone sounds, not how well they lead. Research by Tsedal Neeley shows that less fluent employees often lose status and speak less, even when their expertise is high.

Can leadership training for multicultural teams help with this?

Yes, if it is practical and built around your real team. Managers need to see their own habits, learn what different people expect from a leader, and build tools such as clear promotion criteria. This is the kind of work the BASIS Leadership Programme does one-to-one with managers and CEOs.
