Hot & Not?
A broadly applicable rule-of-thumb is that people find similarity attractive. Generally speaking, the more similar people are, the more likely they are to be attracted to each other and to find an on-going relationship satisfying. McNulty, Neff & Karney (2008) explored similarity in the facial attractiveness of newlyweds. They found that attractiveness ratings correlated at a very modest level (r = .24).
Inter-rater reliabilities were good (the alpha for men’s ratings was .90 and .93 for women).
Couples had all been married for less than 6 months.
Subjects were found via opportunity/convenience sampling and were mostly local, 18-35 year-old, U.S. college students.
Body attractiveness was not considered in this study. Since body/facial attractiveness can be evaluated separately, this is a notable limitation.
This research supports the assertion that people pair-off with similar others and suggests a modest degree of similarity in facial attractiveness in newly married couples. It is possible that including body attractiveness as a variable might alter the strength of this relationship.
[As a methodological aside, I researched my library’s database (PsychArticles), read the relevant full-text article in .pdf format, wrote and then posted this blog entry all from my iPhone. Research has changed a lot from my graduate school days in the library stacks!]
