Thou Shalt not Lie! Exploring and testing countermeasures against faking intentions and faking in selection interviews

Many applicants use faking in interviews to present themselves more favorably than they really are. There is widespread concern that this may affect interview validity. As previous research on countermeasures is sparse, we conducted an exploratory study to identify the most promising countermeasures. For technology-mediated interviews, these were warnings referring to a criterion-based content analysis and lie detection algorithms focusing on nonverbal or paraverbal cues. For face-to-face interviews, these were objective questions and a personable interviewer. We then investigated the effects of these countermeasures on faking intentions in two experimental vignette studies and on faking in another simulated interview study. However, none of the countermeasures could reduce faking intentions or faking. Additionally, in the vignette studies, warnings impaired applicant reactions.
