This investigation tests relationships between three kinds of group self-centeredness and their relationship with negativity towards specific outgroups. A questionnaire study with 270 undergraduates focused on three prominent kinds of group self-centeredness: ethnocentrism, fundamentalism, and anthropocentrism. Although overall ethnocentrism, fundamentalism, and anthropocentrism were positively intercorrelated, fundamentalism was positively associated with one ethnocentrism dimension (intragroup) and negatively with the other (intergroup). A path analysis showed that each kind of group self-centeredness was related only to negativity to specific and relevant outgroups and not to other outgroups. Implications of the research, particularly for the study of religiosity and prejudice, are discussed. Adorno, Frenkel-Brunswik, Levinson, and Sanford (1950) assumed that ethnocentric individuals are particularly prone to be centered on various ingroups and to have generalized negativity towards all those considered as outgroups. This paper will test this idea further by focusing more specifically on three historically and cross-culturally prominent kinds of group self-centeredness, 1 that is, self-centeredness based on one's ethnic group (ethnocentrism), religious group (fundamentalism), and on the human species (anthropocentrism). Although Adorno et al. (1950) focused on human ingroups and outgroups, our analysis will extend their idea to anthropocentrism and dislike of other species. Like ethnic group and religious group selfcenteredness, anthropocentrism involves a clear ingroup and outgroup category, and giving more importance to the ingroup over the outgroup. In addition, implicit in Adorno et al.'s (1950) writings is the suggestion that the outgroups that people reject are based on the relevant ingroup on which they are centered. However, they did not pursue this idea further. Accordingly, we will investigate it, particularly because of its relevance to the study of religiosity and prejudice.
