Rational civil servant interviewers: evidence from an event-related potential study of beauty premiums in Chinese civil servant interviews

摘要

Physical attractiveness can greatly influence business job applications (the beauty premium effect). However, little is known about whether and how physical attractiveness influences interviewers' evaluations of Chinese civil servant applicants, given that many characteristics of civil service appear to be different from those of business jobs. Using event-related potentials (ERPs), the current study investigated how female job candidates' physical attractiveness influenced interviewers' evaluations in Chinese civil servant interviews for both technical and managerial positions. The behavioral results showed that for the managerial positions, attractive female candidates had a much higher acceptance rate than unattractive candidates. However, for the technical positions, no significant difference was found between attractive and unattractive candidates. At the brain level, for the managerial positions, pairs of attractive faces with managerial posts elicited smaller N400 and larger late positive potential (LPP) amplitudes than did pairs of unattractive faces with managerial posts. However, this relationship was not observed for technical posts. The negative correlation between N400 amplitude and acceptance rate as well as the positive correlation between LPP amplitude and acceptance rate further confirmed these results. The present study suggests that beauty could potentially influence if candidates are accepted in real Chinese civil servant interviews, as observed experimentally in this research.
