The relative effects of competence and likability on interpersonal attraction.

Undergraduate students in Singapore (N = 80) learned about the competence (low vs. high) and likability (low vs. high) of a future interaction partner and indicated their attraction toward that stranger. The effect of likability was two times as large as that of competence. Because of the additive effects of the two manipulated factors on attraction, the authors interpreted the preference for lovable fools over competent jerks as an outcome of a generalized supremacy of likability over competence.
