What aspects of ingroup identification can lead people to resist justice for the victims of their ingroup's mistreatment? In three studies carried out in the United States and United Kingdom, in which participants read reports of mistreatment of prisoners and civilians by coalition troops in the Iraq war, ingroup glorification, but not ingroup attachment or(More)
People's self-perception biases often lead them to see themselves as better than the average person (a phenomenon known as self-enhancement). This bias varies across cultures, and variations are typically explained using cultural variables, such as individualism versus collectivism. We propose that socioeconomic differences among societies--specifically,(More)
While evidence suggests that humans have an aversion to directly killing other humans, the phenomenon of extremist violence seems to speak against this. We review evidence in social psychological research for three ways in which people can subjectively overcome moral doubts, justifying past violence and facilitating future violence, on behalf of themselves(More)
Ideological beliefs have long attracted the attention of social psychologists, who have investigated their genesis as well as their influence on a host of social phenomena. Conservatism, from the Motivated Social Cognition framework, stems from epistemic and existential needs of the individual, and notably the fear of death. However, Terror Management(More)

In this(More)
This article contributes to the conceptual and empirical distinction between (the assessment of) appraisals of teaching behavior and (the assessment of) self-reported competence acquirement within academic course evaluation. The Bologna Process, the current higher-education reform in Europe, emphasizes education aimed toward vocationally oriented(More)
Drawing on research on the collapse of compassion and group processes and interrelations, four experiments investigated how labeling a conflict "genocide" affects distant bystanders' support for intervention. The genocide label (compared with no label or the label "not a genocide") weakened Americans' support for intervention in a crisis analogous to(More)
There is a well-established tendency for people to see themselves as better than average (self-enhancement), although the universality of this phenomenon is contested. Much less well-known is the tendency for people to see themselves as more human than average (self-humanizing). We examined these biases in six diverse nations: Australia, Germany, Israel,(More)
Intergroup violence can profoundly affect the health of involved parties. Complementing existing research on ingroup-suffered violence and health, this paper proposes an integrative framework explicating how and why ingroup-committed violence can positively or negatively affect the health of ingroup members. Based on different models of social identity and(More)
