 (Of course, this is not the only case that motivates the need for an epistemology of group testimony. Wikipedia, for instance, presents a number of interesting questions about what it would take for a group to testify, and when and why we should accept what a group says. See, e.g., Tollefsen 2009; Wray 2009; and Fallis 2008. Cases involving testimony from scientific groups also raise similar issues. See, e.g., Hardwig 1985 and Faulkner 2018).
