Ethnocentrism can be seen as an expression of narcissism at the group level. However, the relationship between ethnocentrism and narcissism has rarely been studied, and there is little agreement about what this relationship might be. Both have also been treated as simple, unidimensional constructs, whereas research indicates they are better viewed as complex and multidimensional. New research using multidimensional measures of both constructs was therefore conducted in a sample of 264 undergraduates. Narcissism, primarily its covert form, related positively to intergroup expressions of ethnocentrism, but negatively to intragroup expressions. In addition, both intergroup expressions of ethnocentrism and covert narcissism were related to disliking others. The findings suggest that intergroup expressions of ethnocentrism are based on personal self-aggrandizement, whereas intragroup expressions are based on personal self-transcendence. In addition, they suggest that narcissistic people have generally selfish and exploitative attitudes, even towards their own groups. They also emphasize the importance of investigating both ethnocentrism and narcissism as complex multidimensional constructs.
