Therefore, subconscious racism can influence our visual processing and how our minds work when we are subliminally exposed to faces of different colors. In thinking about crime, for example, social psychologist Jennifer L. Eberhardt (2004) of Stanford University holds that, "blackness is so associated with crime you're ready to pick out these crime objects." Such exposures influence our minds and they can cause subconscious racism in our behavior towards other people or even towards objects. Thus, racist thoughts and actions can arise from stereotypes and fears of which we are not aware. For example, scientists and activists have warned that the use of the stereotype "Nigerian Prince" for referring to advance-fee scammers is racist, i.e. "reducing Nigeria to a nation of scammers and fraudulent princes, as some people still do online, is a stereotype that needs to be called out".
