Empirical evidence shows that secrecy in science has increased over the past decades, partly as a result of the commercialization of science. There is a good prima facie case against secrecy in science. It is part of the traditional ethos of science that it is a collective and open truth-seeking endeavor. In this paper, I will investigate whether secrecy in science can ever be epistemically justified. To answer this question, I first distinguish between different sorts of secrecy. Next, I propose an account of what it is for a practice to be epistemically justified, with the help of work by Alvin Goldman and Philip Kitcher. I then discuss motivations for secrecy in science that are found in the literature to see whether they amount to, or can be turned into, epistemic justifications for secrecy. The conclusion is that, although some forms of secrecy – particularly those motivated by universal moral concerns – are epistemically justified, secrecy that arises from special, often commercial, interests is not.

People increasingly form beliefs based on information gained from automatically filtered internet sources such as search engines. However, the workings of such sources are often opaque, preventing subjects from knowing whether the information provided is biased or incomplete. Users' reliance on internet technologies whose modes of operation are concealed from them raises serious concerns about the justificatory status of the beliefs they end up forming. Yet it is unclear how to address these concerns within standard theories of knowledge and justification. To shed light on the problem, we introduce a novel conceptual framework that clarifies the relations between justified belief, epistemic responsibility, action and the technological resources available to a subject. We argue that justified belief is subject to certain epistemic responsibilities that accompany the subject's particular decision-taking circumstances, and that one typical responsibility is to ascertain, so far as one can, whether the information upon which the judgment will rest is biased or incomplete. What this responsibility comprises is partly determined by the inquiry-enabling technologies available to the subject. We argue that a subject's beliefs that are formed based on internet-filtered information are less justified than they would be if she either knew how filtering worked or relied on additional sources, and that the subject may have the epistemic responsibility to take measures to enhance the justificatory status of such beliefs.

This paper addresses how the anonymity of an assertion affects the epistemological dimension of its production by speakers, and its reception by hearers. After arguing that anonymity does have implications in both respects, I go on to argue that at least some of these implications derive from a warranted diminishment in speakers' and hearers' expectations of one another when there are few mechanisms for enforcing the responsibilities attendant to speech. As a result, I argue, anonymous assertions do not carry the same ‘promise’ of the speaker's relevant epistemic authoritativeness that ordinary assertions do. If this is correct, the phenomenon of anonymity provides us with a lesson regarding ordinary assertions: their aptness for engendering belief in others, and so for communicating knowledge, depends in general on the very publicness of the act of assertion itself.

Two sorts of connections between privacy and knowledge (or lack thereof) have been suggested in the philosophical literature. First, Alvin Goldman has suggested that protecting privacy typically leads to less knowledge being acquired. Second, several other philosophers (e.g. Parent, Matheson, Blaauw and Peels) have claimed that lack of knowledge is definitive of having privacy. In other words, someone not knowing something is necessary and sufficient for someone else having privacy about that thing. Or equivalently, someone knowing something is necessary and sufficient for someone else losing privacy about that thing. In this paper, I argue that both of these suggestions are incorrect. I begin by arguing, contra Goldman, that protecting privacy often leads to more knowledge being acquired. I argue in the remainder of the paper, contra the defenders of the knowledge account of privacy, that someone knowing something is not necessary for someone else losing privacy about that thing.

Privacy is valued by many. But what it means to have privacy remains less than clear. In this paper, I argue that the notion of privacy should be understood in epistemic terms. What it means to have (some degree of) privacy is that other persons do not stand in significant epistemic relations to those truths one wishes to keep private.

It seems obvious that informational privacy has an epistemological component; privacy or lack of privacy concerns certain kinds of epistemic relations between a cogniser and sensitive pieces of information. One striking feature of the fairly substantial philosophical literature on informational privacy is that the nature of this epistemological component of privacy is only sparsely discussed. The main aim of this paper is to shed some light on the epistemological component of informational privacy.

Conjoined with the claim that there is a moral right to privacy, each of the major contemporary accounts of privacy implies a duty of ignorance for those against whom the right is held. In this paper I consider and respond to a compelling argument that challenges these accounts (or the claim about a right to privacy) in the light of this implication. A crucial premise of the argument is that we cannot ever be morally obligated to become ignorant of information we currently know. The plausibility of this premise, I suggest, derives from the thought that there are no epistemically ‘non-drastic’ ways in which we can cause ourselves to become ignorant of what we already know. Drawing on some recent work in the epistemology and psychology of self-deception and forgetting, I seek to undermine this thought, and thus provide a defense against the challenging argument, by arguing that there are indeed such ways.

According to assurance views of testimonial justification, in virtue of the act of testifying a speaker provides an assurance of the truth of what she asserts to the addressee. This assurance provides a special justificatory force and a distinctive normative status to the addressee. It is thought to explain certain asymmetries between addressees and other unintended hearers (bystanders and eavesdroppers), such as the phenomenon that the addressee has a right to blame the speaker for conveying a falsehood but unintended hearers do not, and the phenomenon that the addressee may deflect challenges to his testimonial belief to the speaker but unintended hearers may not. Here I argue that we can do a better job explaining the normative statuses associated with testimony by reference to epistemic norms of assertion and privacy norms. Following Sanford Goldberg, I argue that epistemic norms of assertion, according to which sincere assertion is appropriate only when the asserter possesses certain epistemic goods, can be ‘put to work’ to explain the normative statuses associated with testimony. When these norms are violated, they give hearers the right to blame the speaker, and they also explain why the speaker takes responsibility for the justification of the statement asserted. Norms of privacy, on the other hand, directly exclude eavesdroppers and bystanders from an informational exchange, implying that they have no standing to do many of the things, such as issue challenges or questions to the speaker, that would be normal for conversational participants. This explains asymmetries of normative status associated with testimony in a way logically independent of speaker assurance.
