The problem the parent post is pointing at is that personalities differ among different groups of people.  So that guy who may seem a bit taciturn and therefore, &quot;not a good cultural fit&quot; may actually be a great employee, it&#x27;s just that in his cultural group it&#x27;s not normal to be super bubbly and talkative when you first meet someone.<p>It&#x27;s not about quotas or diversity for diversity&#x27;s sake.  It&#x27;s about recognizing that we all bring our own cultural lens to a situation and not being aware of how that influences your perception can lead to judging great people more negatively because they&#x27;re not like you.<p>The challenge is that one has to be self-aware enough to recognize their own biases and still make some value judgments on personality.
