An interview with researcher, Susan McHale about the impact of gender and culture on how siblings view each other. Susan explores the way that individualistic cultures foster sibling competitiveness and resentment of favoritism. She describes how in some Mexican American families siblings may support the unfair advantage of one successful sibling who then reflects well on them all. She also describes how gender socialization of girls as caregivers is protective to their younger siblings. She cites research that shows how having an older brother is more likely to result in exposure of the younger siblings to risky behaviors as compared to having an older sister. She reiterates the importance of the sibling relationship as a source of longstanding and as yet poorly studied influence on people’s lives. Indeed, one study suggests that adults with positive sibling relationships at age 65 are more likely to be happy and physically healthy.
