<jats:p>In a society in which expertise becomes increasingly specialized, we need to understand how to manage gaps in knowledge between experts in various fields and between experts and the public in general. That need is especially great in the public sphere, where technical understanding and lived experience do not always align. This study attempts to model the process by which discipline-specific topoi filter into common knowledge and general topoi are acknowledged by experts. It first addresses the issue of expertise in complex rhetorical places, then employs Michel Meyer's reinterpretation of ethos, pathos, and logos to show how experts and non-experts in such places negotiate rhetorical relationships. The study then explores the social and rhetorical mechanisms by which ideas become commonplaces, building on the established theory of symbolic convergence. Finally, the study demonstrates proof in principle with a brief analysis of one topos in the Reports of the Immigration Commission (1911).</jats:p>
