The term "microaggression" has experienced a lively existence in the field of psychology since its introduction in 1970s. Sociology has recently come to study microaggressions, yet serious gaps remain in the study of microaggressions. In particular, sociological analysis has not taken into account how exposure to microaggressive interactions may affect racial attitudes, how variations in microaggressive interactions have different effects, and what racial and gender positions render one more or less likely to engage in, or fail to oppose, microaggressions. Based on a GSS-based survey and an experimental vignette design, we address the following two questions: First, how might the presence of racial microaggressions affect racial attitudes? Second, what is the power of specific types of interactional microaggression? Results indicate that both exposure to microaggressions and the type of microaggressions are correlated with changes in specific racial attitudes associated with the marginalization, problematization, and symbolic and physical repression of people of color.
