In a study of elementary school children, when divided into single-gender groups, discussions of the other sex showed rising resentment. It is this inherent suspicion, distrust, and antagonism brought on by segregation, that makes single-sex education a detriment to society. While distrust between the sexes grows, a woman's self-image plummets. As segregation further divides the sexes, women will find it harder to succeed in their careers. Such results are consistent with and help explain Gwen Moore's study of women elites in business and politics.
Sex segregation creates a vicious cycle.
As gender identities become further entrenched, traditional male and female careers will be pursued by the sexes. State-sponsored segregation implies hierarchy. Sociological research indicates that segregated cultures are more repressive and fuel economic and political stratification. Society must be extremely cautious in dealing with gender issues. Sex segregation already abounds in every aspect of our lives.
