Much research has been devoted to the study of socially desirable responding (SDR) on non-cognitive measures of job related characteristics. However, the egoistic component (ego-promotional and ego-defensive) of SDR has not been given enough attention in the literature. In this dissertation I describe deceptive behavior from an evolutionary and cultural perspective. The research on faking and socially desirable responding is thoroughly explored and the notions of ego promotional and ego defensive responding are introduced. These discussions lead to two research studies examining 1) how egoistic behavior affects self appraised job performance and responses to biographical questionnaire and 2) whether SDR scales can measure actual deception in a pre-employment testing context.
