groom, the less likely their marriage is to succeed (Amato, Johnson, 
Booth, & Rogers, 2003). That may be because, as Erikson pointed out, 
intimacy is hard to establish until identity is secure. Thus, in a series of 
studies, college students who were less advanced on Erikson’s identity 
and intimacy stages tended to defi ne love in terms of passion, not inti-
macy or commitment — butterfl ies and excitement, not openness, trust, 
and loyalty (Aron & Westbay, 1996).
3    A second infl uence on marital success is the degree of similarity 
between husband and wife. Anthropologists distinguish between homog-
amy, or marriage within the same tribe or ethnic group, and heterog-
amy, or marriage outside the group. Traditionally, homogamy meant 
marriage between people of the same cohort, religion, socioeconomic 
status, ethnicity, and education. For contemporary marriages, homog-
amy and heterogamy refer to similarity [and difference, respectively] in 
interests, attitudes, and goals (Cramer, 1998).
4    One study of 168 young couples found that social homogamy, 
 defi ned as similarity in leisure interests and role preferences, is particu-
larly important to marital success (Houts, Robins, & Huston, 1996). 
For instance, if both spouses enjoyed (or hated) picnicking, dancing, 
swimming, going to the movies, listening to music, eating out, or enter-
taining friends, the partners tended to be more “in love” and more com-
mitted to the relationship. Similarly, if the two agreed on who should 
make meals, pay bills, shop for groceries, and so on, then ambivalence 
and confl ict were reduced.
5    A third factor affecting the success of a marriage is

marital 
equity, the extent to which the two partners perceive a rough equal-
ity in the partnership. In many modern marriages, the equity that is 
sought is in shared contributions. Both partners expect equality and 
sensitivity to their needs regarding dependence, sexual desire, shared 
confi dences, and so on, and happier marriages are those in which both 
partners are adept at emotional perception and expression (Fitness, 
2001). What matters most is the perception of fairness, not absolute 
equality.
