Microaggressions are subtle insults (verbal, nonverbal, and/or visual) directed toward people of color, often automatically or unconsciously. Using critical race theory as a framework, the study described in this article provides an examination of racial microaggressions and how they influence the collegiate racial climate. Using focus group interview data from African American students at three universities, it reveals that racial microaggressions exist in both academic and social spaces in the collegiate environment. The study shows how African American students experience and respond to racial microaggressions. It also demonstrates how racial microaggressions have a negative impact on the campus racial climate.
