What is it about?
People are usually good at noticing what is present in their environment, but much less good at noticing what is absent. This paper shows that this basic feature of the mind has important social consequences: people often fail to notice when members of minority groups are missing from social settings. Across field studies and controlled experiments, we found that people frequently overlooked the absence of minority-group members in places such as universities, conferences, classrooms, and workplaces. This happened even when the absence was meaningful, even when participants cared about diversity, and even when they were motivated to be accurate. By contrast, people were more likely to notice when minority-group members were present, or when majority-group members were absent. These findings suggest that our impressions of diversity can be biased. Minority presence tends to stand out, while minority absence can disappear from awareness. As a result, social environments may seem more inclusive or diverse than they really are.

Why is it important?
This work identifies a bias in social perception that can make inequality harder to recognize. Underrepresentation is not only difficult to solve; it may also be difficult to see. If people do not notice that a group is missing from a setting, they are less likely to view the absence as a problem or support efforts to address it. The findings are timely because debates about diversity and inclusion often assume that people are responding to the same social reality. Our research suggests that this is not always the case: basic cognitive processes can shape what people notice, remember, and treat as meaningful. By showing that minority absence is often overlooked, this work helps explain why underrepresentation can persist even in environments where people endorse egalitarian values.
Perspectives
This article grew out of a question that kept bothering me: how can meaningful forms of inequality remain so easy not to see? We often think of diversity as something people notice directly, but this work suggests that our impressions of social environments are shaped by a simple cognitive asymmetry. We notice who is there much more easily than who is missing. What I find most striking about these findings is that they do not simply point to a lack of concern. Many people in our studies cared about the absence once it was pointed out to them. The problem was that they had not noticed it before. To me, this makes the findings both unsettling and hopeful. Unsettling, because it means that inequality can persist partly by remaining outside awareness. Hopeful, because it suggests that one small but powerful step is to ask, more deliberately and more often: who is missing?
