Interethnic Bias in Willingness to Engage in Casual Sex Versus Committed Relationships.

Interethnic romantic relationships are widely seen as a strong indicator of a well-integrated society. However, racial bias may still be evident in the tendency to engage in casual sex versus committed relationships. Using a large, age-diverse sample of 3,453 White British participants, this study found a general preference for White partners over racial minority partners. Furthermore, in line with social structural theory, participants reported a relative preference for marriage (versus casual sex) with White partners, but a relative preference for casual sex (versus marriage) with racial minorities. This pattern was further modified by sex: Men reported a general preference for casual sex (versus marriage) with all racial groups except White partners. Women, however, reported a general preference for marriage (versus casual sex) with all groups, but this preference was strongest for White partners. The pattern was not further modified by sexual orientation. Implications for contemporary interethnic romantic relationships are discussed.
