Summary
Ingratiation seems to be extremely useful in the initial stage of interpersonal interaction. Recently, scholars have drawn attention to the role of ingratiation in the special context of newcomer socialization, arguing that ingratiation can help newcomers build a positive image in the work setting. In this research, we first propose that two types of ingratiation—excessive ingratiation and seamless ingratiation—can be distinguished and develop a measurement instrument for them. Second, based on affective events theory, we explore how newcomers’ excessive ingratiation and seamless ingratiation lead to different socialization outcomes by stimulating distinct emotional and behavioral responses from their supervisors. The results of two experiments and a multisource weekly survey conducted for 10 consecutive weeks reveal that newcomers’ excessive ingratiation triggers supervisors’ embarrassment and interaction avoidance, and ultimately hinders newcomer socialization; in contrast, seamless ingratiation evokes supervisors’ pride and information sharing and ultimately promotes socialization outcomes. Supervisor narcissism weakens the relationship between excessive ingratiation and embarrassment but strengthens the relationship between seamless ingratiation and pride. Theoretical contributions, practical implications, and directions for future research are discussed.
