The term "equallyoked" refers to couples who share similar civil identities in key areas such as ethnicity, religion, politics, race, age, gender, and marital status. It originated from the Bible's encouragement of people of the same religion marrying within their own group. Equallyoked couples are of interest to social psychologists because they represent dyadic groups sharing the same civil identity, and their marriages may contribute to longevity and higher self-esteem due to sharing backgrounds. The concept of equallyokedtarianism is relevant to the study of sociology, social psychology, marriage and family psychology, as it represents a social norm for community well-being in multicultural societies.
