Singles in society and in science

We suggest that single adults in contemporary American society are targets of stereotyping, prejudice, and discrimination, a phenomenon we will call singlism. Singlism is an outgrowth of a largely uncontested set of beliefs, the Ideology of Marriage and Family. Its premises include the assumptions that the sexual partnership is the one truly important peer relationship and that people who have such partnerships are happier and more fulfilled than those who do not. We use published claims about the greater happiness of married people to illustrate how the scientific enterprise seems to be influenced by the ideology. We propose that people who are single-particularly women who have always been single-fare better than the ideology would predict because they do have positive, enduring, and important interpersonal relationships. The persistence of singlism is especially puzzling considering that actual differences based on civil (marital) status seem to be qualified and small, the number of singles is growing, and sensitivity to other varieties of prejudice is acute. By way of explanation, we consider arguments from evolutionary psychology, attachment theory, a social problems perspective, the growth of the cult of the couple, and the appeal of an ideology that offers a simple and compelling worldview.
