Abstract
Research exploring the effects of physical attractiveness frequently assesses attractiveness by employing subjective appraisals by independent raters. However, there is reason to believe that rater characteristics - especially their sex - may systematically bias subjective ratings of physical attractiveness. The current study explores this possibility by analyzing data from the National Longitudinal Study of Adolescent Health (N = 13,330). Analyses of these data revealed that ratings of physical attractiveness are significantly influenced by the sex of the interviewer/rater. Specifically, male raters were significantly less likely than female raters to assess males as attractive, very attractive, and very unattractive. The results are explained within the context of evolutionary psychology and illustrate a methodological concern for research on physical attractiveness. (C) 2011 Elsevier Ltd. All rights reserved.
