I think it&#x27;s obvious that diversity can be both good and bad.<p>A team where everyone speaks a different language is very diverse, but not effective, since there is no communication. One in which they at least share some common language which for all of them is a second language, not with full fluency, would be able to function, but likely not as efficiently as one in which everyone speaks the same language as their mother tongue.<p>And language can be just an analogy. Instead of language, imagine a cultural background of shared assumptions and experiences. A shared background can help avoid misunderstandings and speed up communication.<p>At the same time, it&#x27;s clear that diversity can help in many ways, avoiding single-mindedness, for example. If everyone has the same concepts and background, they might miss something important.<p>For political reasons, people like to say that diversity is good, and it is indeed good in some ways. But that&#x27;s far from the whole story.<p>It would be better to not use &quot;diversity is good for business&quot; as a slogan, when there are other more valid reasons to fix issues with inclusion where they exist.
