Social intelligence and interview accuracy: Individual differences in the ability to construct interviews and rate accurately

This research examined differences in interviewers’ ability to identify effective interview questions and to accurately rate interviewees’ responses. Given the theoretical association between these interview activities and the construct of social intelligence (SI), a performance-based measure of SI was developed utilizing situational judgment test methodology. The initial step was to examine evidence of the psychometric properties and construct validity of the new SI measure. The SI measure, a test of general mental ability (GMA), and a personality inventory were then used to examine aspects of rater performance. Participants chose a set of interview questions and viewed interviewee responses during a videotaped interview. Results showed that people higher in SI and GMA chose interview questions judged by experts to be superior and were more accurate in rating interviewee responses. The SI measure explained variance beyond GMA and outperformed a trait-based SI measure. Implications for the selection and training of interviewers are discussed.
