In social psychology, social projection is the psychological process through which an individual expects behaviors or attitudes of others to be similar to their own. Social projection occurs between individuals as well as across ingroup and outgroup contexts in a variety of domains. Research has shown that aspects of social categorization affect the extent to which social projection occurs. Cognitive and motivational approaches have been used to understand the psychological underpinnings of social projection as a phenomenon. Cognitive approaches emphasize social projection as a heuristic, while motivational approaches contextualize social projection as a means to feel connected to others. In contemporary research on social projection, researchers work to further distinguish between the effects of social projection and self-stereotyping on the individual’s perception of others. The term social projection was first coined by Floyd Allport in 1924. The idea refers to the process of creating knowledge about the characteristics of an individual or group of individuals based on the self as a reference point. Building off Leon Festinger’s theory of social comparisons, researchers became interested in how attitudes about groups or individuals were created in the absence of information about the comparison group. Modern investigation of social projection diverges from Festinger’s conception of social comparison theory by emphasizing that the consensus creation process is an implicit rather than explicit phenomenon. Further, the process can and does occur without clear information about the true consensus of the individual or reference group. The classic study by Ross, Greene, and House(1977) on the false consensus effect sparked further interest in how social projection processes lead individuals to believe that their own behaviors and beliefs are common among other individuals. Research has since shown that this phenomenon has links to the projection of attitudes, behaviors, and beliefs onto others in a wide variety of social contexts.
