Being Dr. Jekyll and Mr. Hyde: Role-Based Identity Foils in Organizational Life
研究某些职业要求个体同时扮演对立角色（如军医既要救人又要杀人）的现象，提出身份对立的概念，并分析个体应对这种矛盾的策略及其对绩效和可信度的影响。
Soldier-medic. Undercover police officer. Collaborative divorce attorney. Certain jobs require an individual to enact antithetical sets of role expectations (to do X and not-X), such as saving a life and taking a life, in the case of a soldier-medic. Despite their important consequences, we lack a unifying framework for such antithetical expectations and their implied identity foils—where one is expected to be both Dr. Jekyll and Mr. Hyde (a life-saver and a life-taker). To this end, we build theory on how and why antithetical expectations and their implied identity foils arise in organizations. We offer a model of the responses through which individuals tend to manage these seemingly impossible binds—avoidance, favoritism, gray compromise, black-and-white compromise, and holism—and discuss the conditions under which a given response is likely. We conclude that this respective order of responses predicts more positive outcomes (i.e., clarifying the identities, fostering resources, enabling complementary or synergistic solutions) and less negative outcomes (i.e., impaired jobholder performance and credibility, increased cynicism) for individuals and their organizations. We theorize that, given certain conditions, the extreme role-based conflict caused by identity foils is best addressed by the response of holism.
