DescriptionIn this dissertation, I address recent calls for empirical research on religiosity and ethics in the management-organizational literature by focusing on sacredness, an important aspect of religiosity. In this dissertation, I integrate a psychological view of religiosity as an individual disposition (i.e. homo religiosus) and a sociological notion of “the sacred,” which theoretically can be anything. In Study 1 (N = 585), I create an instrument for exploring “the sacred” and explore how it relates to values, religiosity-related constructs (e.g. intrinsic religiosity) and moral dispositional constructs (e.g. moral disengagement propensity). In this initial study, I discover two forms of individual sacredness: materialism and traditional religion. In a second data collection (N = 521), I confirm the existence of the first two forms of sacredness (materialism and traditional religion) and discover a third form of sacredness: virtue. In Studies 2, 3 and 4, I conduct pretests that explore study manipulations and instruments to be used in tests of the relationship between sacredness and ethical and unethical work behavior. In Study 5 (undergraduate sample; N = 421) and Study 6 (adult sample; N = 100), I test the relationship between forms of sacredness (materialism, traditional religion, virtue), situational factors (self-transcending and self-enhancing situations) and ethical and unethical work behaviors. In Study 5, I find those who sacralize virtue are less likely to exhibit unethical work behavior (measured by lying about performance). I also find evidence that exposure to a self-transcending situation (versus a self-enhancing situation) causes students who sacralize materialism to engage in more ethical work behavior (measured by willingness to engage in a voluntary act). In Study 6, I find those who sacralize traditional religion and virtue are more likely to exhibit ethical work behavior (measured by the willingness to volunteer once and multiple times) while those who sacralize materialism are more likely to exhibit unethical work behavior (measured by lying about performance). Taken together, the results of my empirical studies provide support for the complexity of religious phenomena and a possible explanation at how being religious can be associated with something morally “good” and “bad” at the same time.
