The Similarity Trap

Obvious difference makes us careful. Familiarity makes us careless.

When something is clearly foreign, the language, the food, the way people greet each other, we expect to misunderstand it. So we ask questions. We watch for confusion. We explain things more than once. We assume, correctly, that we don't already know how this works.

The harder case is the opposite one: an environment that looks familiar enough that we stop doing any of that.

That's the Similarity Trap. Not dramatic cultural difference, but unexamined similarity: the assumption that because something looks the same, it works the same.

Difference puts us on alert. Similarity turns the alert off.

When two cultures share enough surface features, similar office buildings, similar job titles, similar business vocabulary, similar-looking meetings, it becomes easy to assume the underlying expectations are shared too: that the same words carry the same meaning, that a nod means the same thing, that silence means the same thing, that "yes" means the same thing.

None of that is guaranteed. Surface similarity and underlying expectation are two different things, and the gap between them is exactly where the trap sits.

I've described the experience of working in Japan as feeling "just like America until it isn't." Not literally. Japan offers a lot of surface familiarity to an outsider: modern offices, recognizable professional roles, global brands, technology, and business vocabulary that feel immediately legible.

That familiarity is real. It's also exactly what makes deeper differences easy to miss, because there's less obvious signal telling you to slow down and check.

The same pattern shows up in cross-cultural business work between Japan and Vietnam. Both are often described with similar shorthand: hierarchical, relationship-oriented, indirect, face-conscious. Those labels aren't wrong, exactly, but they can create a false sense that two cultures carrying similar labels will interact easily because they appear to share characteristics.

They don't guarantee that. Similar labels don't mean similar expectations. How hierarchy is actually expressed, when a subordinate can disagree, what a polite yes actually means, how quickly a decision is expected, and who's expected to speak first are specific questions. The answers don't transfer just because two cultures share a general description.

None of this is abstract.

It shows up in ordinary work: instructions that seem understood but weren't, agreement that means something different to each side, silence a manager reads as acceptance when it wasn't, or a request one side treats as optional and the other treats as mandatory.

It shows up as frustration that gets chalked up to someone's personality when the real issue is a mismatch in expectations that nobody named.

These aren't necessarily failures of goodwill. Often, they're failures of checking. The risk becomes easier to miss when the situation looks familiar enough that nobody thinks to check.

The answer isn't to memorize more cultural facts.

Facts run out, and they can flatten people into categories anyway. The more durable habit is simpler: keep checking, especially when a situation looks familiar enough that checking feels unnecessary.

A few questions worth carrying into any cross-cultural working relationship:

• What does agreement actually look like here?
• How do people signal uncertainty, if they signal it at all?
• How do I know someone actually understood, not just that they said yes?
• Who is actually allowed to challenge a decision, and how?
• What is everyone in this room assuming is obvious?
• Where might we be using the same word for two different expectations?

None of these require expertise in the other culture. They require a willingness to notice when you've stopped asking.

The more alike two cultures appear, the easier it is to stop checking.

The work is noticing when you have.
