Beautiful faces in pain: Biases and accuracy in the perception of pain

The impact of appearance-based information on judgments about the psychological functioning of pain patients was investigated. Video-tapes of low back pain patients experiencing pain were used as stimulus materials. Subjects viewed silent video clips and photographs of the patients' faces and made judgments about the functioning of these patients. These judgments were affected both by patient physical attractiveness and gender. Physically attractive patients and male patients were judged to be functioning better than physically unattractive and female patients. The judgments were reasonably described as biased because the perceived differences about patients varying in attractiveness and sex were not associated with measures of actual patient functioning.
