Following the recent practice turn in privacy research, informational privacy is increasingly analyzed with regard to the “appropriate flow of information” within a given practice, which preserves the “contextual integrity” of that practice (Nissenbaum, 2010, p. 149; 2015). Such a practice-theoretical take on privacy emphasizes the normative structure of practices as well as its structural injustices and power asymmetries, rather than focusing on the intentions and moral considerations of individual or institutional actors. Since privacy norms are seen to be institutionalized (...) via the role obligations of the practice's participants, this approach can analyze structural and systematic privacy infringements in terms of “defective role performances and defective social relations” (Roessler & Mokrosinska, 2013, p. 780). -/- Unfortunately, it is still often somewhat unclear what this exactly means within the context of informational privacy, why these performances and relations are defective and for whom. This raises the common objection of a so-called “practice positivism” (Applbaum, 1999, p. 51), that is, the difficulty of practice–theoretical accounts to take a practice-independent standpoint, from which to normatively evaluate the existing practice norms themselves. For example, Nissenbaum herself initially argues for a “presumption in favor of the status quo” with respect to the appropriateness and flow of privacy norms within a practice (Nissenbaum, 2004, p. 127). Such a “practice conservatism” (Nissenbaum, 2010, p. 169) comes dangerously close to committing a naturalistic fallacy, if not undergirded by practice-external criteria (which is ultimately what she does). -/- Merely resorting to existing practice norms to assess what defective role performances amount to, only shifts the question from how to recognize an appropriate flow of information to the question of how to recognize those defective role performances and social relations. Against this backdrop, the central aim of this article is to shed light on this question without resorting to practice-independent first principles or far-reaching universalistic anthropological assumptions. For this, I will analyze the notion of “defective role performances and social relations” in terms of social pathologies.1 Doing so has two advantages: First of all, it can draw on already existing concepts and distinctions, which help to categorize the different levels of analysis that exist in informational privacy research and situate the notion of “defective role performances” within them (Section 1). Second, those concepts and distinctions can serve as a basis for establishing a typology of phenomena with regard to deficient practices of informational privacy (Section 4). (shrink)
