RT Dissertation/Thesis T1 The psychology of privacy: Analyzing processes of media use and interpersonal communication A1 Dienlin,Tobias WP 2017/02/24 AB What is the psychology of privacy? How do people perceive privacy? Why do people disclose personal information on the Internet, and what does this reveal about our their personalities? With four studies, this cumulative dissertation discusses potential answers to these questions. Study 1 (“The Privacy Process Model”) proposes a new privacy theory, the so-called Privacy Process Model (PPM). The PPM states that privacy consists of three major elements: the privacy context, the privacy perception, and the privacy behavior. In order to balance the three elements people constantly engage in a privacy regulation process, which can be either explicit/conscious or implicit/subconscious. Through concrete examples of new digital media, several implications of the PPM are demonstrated. Study 2 (“Is the Privacy Paradox a Relic of the Past?”), which is co-authored by Prof. Dr. Sabine Trepte, analyzes the privacy paradox through the results of an online questionnaire with 579 respondents from Germany. By adopting a theory of planned behavior-based approach, the results showed that self-disclosure could be explained by privacy intentions, privacy attitudes, and privacy concerns. These findings could be generalized for three different privacy dimensions: informational, social, and psychological privacy behaviors. Altogether, Study 2 therefore suggests that the privacy paradox does not exist. Study 3 (“An Extended Privacy Calculus Model for SNSs”), co-authored by Prof. Dr. Miriam J. Metzger, builds upon the results of Study 2 and investigates whether psychological antecedents can explain not only online self-disclosure but also online self-withdrawal. Using a privacy calculus-based approach, the study analyzes data from a U.S.-representative online sample with 1,156 respondents. The results showed that self-disclosure could be explained both by privacy concerns and expected benefits. In addition, self-withdrawal could also be predicted by both privacy concerns and privacy self-efficacy. In conclusion, Study 3 demonstrates that perceived benefits, privacy self-efficacy, and privacy concerns together predict both online self-disclosure and online self-withdrawal. Study 4 (“Predicting the Desire for Privacy”), also co-authored by Miriam J. Metzger, analyzes the relationship between the desire for privacy and different facets of personality. In Study 4a, an online questionnaire with 296 respondents was conducted and in Study 4b, a laboratory experiment with 87 participants was run. The results of the questionnaire showed several significant relationships: For example, respondents who reported lacking integrity and being more shy, less anxious, and more risk averse were all more likely to desire privacy. The experiment showed a statistical trend that participants who had written an essay about past negative behaviors were more likely to express an increased desire for privacy from other people; in addition, an implicit association test (IAT) showed that participants whose IAT results implied higher lack of integrity also desired more privacy from government surveillance. In conclusion, the results evidence that the desire for privacy relates with several aspects of personality and, notably, also with personal integrity. In the overarching discussion, the results of the aforementioned studies are combined in order to provide an updated picture of privacy. This picture suggests that online self-disclosure is not paradoxical but explainable. Being able to understand online privacy behaviors is important; however, this is not only because the Internet has paramount importance in social and professional contexts, but also because people’s desire for privacy can reveal central aspects of personality, such as one’s own personal integrity. Finally, several societal implications are discussed. It is argued that modern societies should try to design new cultural artifacts about privacy, update old and obsolete behavioral patterns with regard to privacy, foster a better understanding of the conceptual nature of privacy, work toward new and more protective privacy laws, and aim to leverage overall privacy literacy.
