Our cognitive processes are largely shaped by what is present in our environment, while absences are often overlooked. This fundamental tendency of the human mind can lead to a significant social bias: individuals frequently fail to notice the absence of minority groups, even in situations where that absence is meaningful and consequential (e.g., educational settings, workplaces). In three preregistered field studies conducted across two cultures, we found robust evidence for blindness to minority absence. Our findings reveal that this blindness can persist for years, even among individuals who, once the absence is pointed out, acknowledge its significance and the need to address it. Eight preregistered laboratory experiments confirm that people are unlikely to detect the absence of a minority group. As our results indicate, people are more likely to notice the presence of a single minority member than the group’s complete absence. In contrast, the absence of majority group members is far more noticeable. These patterns emerge even when monetary incentives for accuracy are introduced, regardless of participants’ ideologies or social attitudes, and are evident even among individuals from minority groups. The final experiment suggests that highlighting an overlooked minority absence leads to higher stated support for diversity-promoting policies. Taken together, our findings suggest that basic cognitive constraints bias what people spontaneously notice in social environments: minority absences often go unnoticed, while majority absences and minority presences are more readily perceived. We propose that this bias may present a significant barrier to fostering inclusive social environments.
