A case of mistaken identity: Miscategorisation of the ingroup as a historically...

Guerra, R.; Golec de Zavala, Agnieszka; Bierwiaczonek, K.; Ciesielski, P.; Abakoumkin, G.; Wildschut, T.; Sedikides, C.

Collective narcissism’s links with intergroup relations, such as intergroup hostility, are well established, but less is known about the intergroup conditions that trigger it. We experimentally examined whether categorisation threat—operationalised as mistaking the ingroup for a historically rivalrous outgroup, thus undermining the ingroup’s uniqueness—heightens collective narcissism, and whether this, in turn,...

Agentic collective narcissism and communal collective narcissism: Do they predi...

Zemojtel-Piotrowska, M.; Sawicki, A.; Piotrowski, J.; Lifshin, U.; Kretchner, M.; Skowronski, J. J.; Sedikides, C.; Jonason, P. K.; Adamovic, M.

In a multinational study (61 countries; N = 15,039), we examined how collective narcissists, both agentic (ACN) and communal (CCN), reacted cognitively (through endorsement of unfounded conspiracy and health beliefs) and behaviorally (via prevention, hoarding, and prosociality) to the pandemic. Higher ACN and CCN predicted greater endorsement of COVID-19 unfounded beliefs and higher likelihood of having recentl...

A theoretical perspective on grandiose narcissism suggests four forms of it (sanctity, admiration, heroism, rivalry) and states that these forms conduce to different ways of thinking and acting. Guided by this perspective, we examined in a multinational and multicultural study (61 countries; N = 15,039) how narcissism forms are linked to cognitions and behaviors prompted by the COVID-19 pandemic. As expected, d...

Milieu effects on the Dark Triad traits and their sex differences in 49 countries

Jonason, P. K.; Czerwiński, S. K.; Tobaldo, F.; Ramos-Diaz, J.; Adamovic, M.; Adams, B. G.; Ardi, A.; Baltatescu, S.; Cha, Y. S.; Chobthamkit, P.

Most research on the development of personality traits like the Dark Triad (i.e., narcissism, Machiavellianism, and psychopathy) focuses on local effects like parenting style or attachment, but people live in a larger society that may set the stage for any local effects. Here we paired nation-level data on the traits from 49 nations with several milieu indicators (e.g., life expectancy, homicide rates) from thr...

An intergroup approach to collective narcissism: intergroup threats and hostili...

Guerra, R.; Bierwiaczonek, K.; Ferreira, M.; Golec, A.; Abakoumkin, G.; Wildschut, T.; Sedikides, C.

Although it is known that collective narcissism is associated with problematic intergroup relations, its predictors are less well understood. Two studies, conducted in four European Union countries (Germany, Greece, Portugal, the United Kingdom [UK]), tested the hypotheses that integrated (i.e., realistic and symbolic) threat (Study 1, N = 936) as well as distinctiveness threat (Study 2, N = 434) positively pre...

Rogoza, R.; Zemojtel-Piotrowska, M.; Jonason, P. K.; Piotrowski, J.; Campbell, K. W.; Gebauer, J. E.; Maltby, J.; Sedikides, C.; Adamovic, M.

The Dark Triad (i.e., narcissism, psychopathy, Machiavellianism) has garnered intense attention over the past 15 years. We examined the structure of these traits' measure-the Dark Triad Dirty Dozen (DTDD)-in a sample of 11,488 participants from three W.E.I.R.D. (i.e., North America, Oceania, Western Europe) and five non-W.E.I.R.D. (i.e., Asia, Middle East, non-Western Europe, South America, sub-Saharan Africa) ...

Low self-esteem predicts out-group derogation via collective narcissism, but th...

de Zavala, A. G.; Federico, C. M.; Sedikides, C.; Guerra, R.; Lantos, D.; Mroziński, B.; Cypryańska, M.; Baran, T.

According to social identity theory, low self-esteem motivates group members to derogate outgroups, thus achieving positive in-group distinctiveness and boosting self-esteem. According to the Frankfurt School and status politics theorists, low self-esteem motivates collective narcissism (i.e., resentment for insufficient external recognition of the in-group's importance), which predicts out-group derogation. Em...
