Narcissistic individuals (i.e., those scoring higher on narcissism) seek agentic pursuits, such as social status, power, and achievement. They seem to be successful in these pursuits as they are more likely to occupy influential positions, giving them leeway to exert significant impact on others. However, narcissistic individuals’ tendencies to disregard communal values, as reflected in their self-focus, lack of empathy, hostility, and sense of entitlement, can have negative interpersonal consequences. To better understand their social influence, we investigated how narcissistic individuals process and respond to communal features of their social environment, which is relevant for both their own functioning as well as the functioning of social collectives. In Chapters 2-4, we report a series of studies investigating what social information narcissistic individuals attend to, what social information they use to select people to interact with, and how they evaluate and behaviorally respond to social information. In Chapter 2, we found that narcissistic individuals selected relatively more antisocial and less prosocial information. Chapter 3 revealed that narcissistic individuals showed lower preferences for sociability traits in prospective partners under lower situational threat, but this effect was muted or even reversed when threat was higher. Preference for morality traits remained lower irrespective of threat. Chapter 4 showed that narcissistic individuals were less responsive to variations in others’ antisocial and prosocial behavior, both in terms of their evaluations and behavioral responses. These findings suggest that how narcissistic individuals process and respond to the communal world is reflective of their own character and proclivities.
