Imagine any situation where leaders and other authority figures come from stereotypically non-traditional leadership backgrounds: women, people of color, non-college graduates, recent immigrants, and so on. Ideally, these individuals should be evaluated based on their ability; instead, individuals can prefer authority figures from stereotypically traditional backgrounds while setting ability to the side (e.g., Carton & Rosette, 2011; Cook & Glass, 2013; McDonald et al., 2018; Rosette & Livingston, 2012). These authority figures are often hurt by negative stereotypes-but what leads us to accept these stereotypes in the first place?When we are under a tight deadline, when we are faced with competing answers, when we need to be certain about something important in our social worlds, we can crave the stability of even very harmful stereotypes-even if we are ourselves hurt by them.We propose that the mere desire for stable knowledge can help explain why we can depreciate authorities that violate traditional stereotypes; we will investigate this issue in the context of women in positions of authority and the harmful stereotypes about women that can make their position tenuous. Even if political liberals are less likely to accept these stereotypes, we argue that liberals are particularly at-risk for these outcomes when they are also driven by this desire for stable knowledge.
