This article analyzes the demarcations made within psychology as a feature of the “memory wars”—the current controversy around “recovered” or “false” memory. As it is played out inside professional psychology, the dispute features clinical practitioners acting largely as proponents of recovered memory and experimentalists as proponents of false memory. Tracing a genealogy of this dispute back to a pair of original sites, we show how the traditions’engagement in three modes of scientific demonstration varies systematically in terms of the modes of (...) social relation inherent in their epistemic practices and the kinds of “reliable witness” these practices produce. We conclude that whereas the experimentalist tradition is able to transporttheir produced witnesses from oneto anothersite of demonstration with relative ease, the clinical tradition has much greater difficulty in doing so and thus has to engage in a variety of compensatory demonstrative strategies.
