Purpose - We investigate the antibias norm, ''political correctness'' (PC), and explore the consequences of the PC norm for group processes and group performance. Methodology/approach - We define the term PC as it is used in public discourse and distinguish the PC norm from the related antibias norm of color blindness. Findings - We suggest that the PC norm may play a unique role in reducing a critical type of uncertainty that would otherwise constrain performance, in particular, group creativity and decision making, in diverse work groups. We then explore the controversial argument that being politically incorrect can actually promote freedom of expression. Originality/value of chapter - We conclude by reflecting on the costs of the PC norm and why the PC norm may remain prevalent in work groups for some time to come.
