A study published in the Journal of Experimental Social Psychology found that while gender stereotypes are often seen as misleading, they are surprisingly accurate. People accurately guess whether men or women are superior in a given trait about 85% of the time. The accuracy of social perception has long been a subject of interest to psychologists, particularly with regard to stereotypes, which refer to commonly shared beliefs about social groups. While some studies suggest that stereotypes are often exaggerated or biased, others argue that they contain "grains of truth."
