We present a study on the importance of masculine and feminine honor and attitudes towards sex roles in Spain and the Netherlands. Honor is more important in Spanish than in Dutch culture. Participants were asked to rate the extent to which gender-neutral (e.g., caring for reputation) and gendered (e.g., assertiveness, modesty) honor attributes were desirable in their culture for each sex. We also measured attitudes towards sex-roles in different domains (e.g., work, marriage). The Spanish participants rated gender-neutral honor attributes as more desirable than the Dutch participants did. Both Spanish and Dutch participants rated masculine honor attributes as more desirable for men, and,feminine honor attributes as more desirable for women. Participant's sex emerged as the most important predictor of attitudes towards sex roles, with males expressing more traditional attitudes than females. Taken together, the results indicate that masculine and feminine honor are expressions of pan-cultural ideals of masculinity and femininity.
