effects upon the possibilities to create, acquire and spread knowledge is a subject of continuous debate. The most common topics discussed in contemporary social epistemology are testimony (e.g. "When does a belief that x is true which resulted from being told 'x is true' constitute knowledge?"), peer disagreement (e.g. "When and how should I revise my beliefs in light of other people holding beliefs that contradict mine?", and group epistemology (e.g. "What does it mean to attribute knowledge to groups rather than individuals, and when are such knowledge attributions appropriate?"). Within the field, "the social" is approached in two complementary and not mutually exclusive ways: "the social" character of knowledge can either be approached through inquiries in inter-individual epistemic relations or through inquiries focusing on epistemic communities. The inter-individual approach typically focuses on issues such as testimony, epistemic trust as a form of trust placed by one individual in another, epistemic dependence, epistemic authority, etc. The community approach typically focuses on issues such as community standards of justification, community procedures of critique, diversity, epistemic justice, and collective knowledge. Social epistemology as a field within analytic philosophy has close ties to, and often overlaps with philosophy of science. While parts of the field engage in abstract, normative considerations of knowledge creation and dissemination, other parts of the field are "naturalized epistemology" in the sense that they draw on empirically gained insights---which could mean natural science research from, e.g., cognitive psychology, be that qualitative or quantitative social science research. (For the notion of "naturalized epistemology" see Willard Van Orman Quine.) And while parts of the field are concerned with analytic considerations of rather general character, case-based and domain-specific inquiries in, e.g., knowledge creation in collaborative scientific practice, knowledge exchange on online platforms or knowledge gained in learning institutions play an increasing role. Important academic journals for social epistemology as a field within analytic philosophy are, e.g., Episteme, Social Epistemology, and Synthese. However, major works within this field are also published in journals that predominantly address philosophers of science and psychology or in interdisciplinary journals which focus on particular domains of inquiry (such as, e.g., Ethics and Information Technology).
