What Happens When You Can’t Check the Box? Categorization Threat and Public Opinion among Middle Eastern and North African Americans

Middle Eastern and North African (MENA) Americans are politically visible yet institutionally invisible, long categorized as “white” by the U.S. government despite neither self-categorizing nor racially assigned as such. Most forms—across public and private sectors—still lack a “MENA” category option. What are the political consequences of institutional invisibility? Across two survey experiments and in-depth interviews, I find that exclusion from official identity categories triggers the experience of categorization threat, a psychological response rarely linked to political behavior. When MENA Americans experience categorization threat, they respond by expressing opinions on politics in ways that attempt to signal and assert their MENA identity and, to a lesser extent, Person of Color (POC) identity. Such identity assertion demonstrates that bureaucratic categorization influences expressions of public opinion on politics, not simply how people self-categorize. Researching the effects of category exclusion on public opinions creates opportunities for more accurate and democratic scholarship.
