Major current models of persuasion depict it as attainable via 2 qualitatively distinct routes: (a) a central or a systematic route in which opinions and attitudes are based on carefully processed arguments in the persuasive message and (b) a peripheral or heuristic route in which they are based on briefly considered heuristics or cues, exogenous to the message. This article offers a single-route reconceptualization that treats these dual routes to persuasion as involving functionally equivalent types of evidence from which persuasive conclusions may be drawn. Previous findings in the dual-process literature are reconsidered in light of this "unimodel," and data from 4 new studies testing the unimodel are presented consistent with its assumptions. Implications of the unimodel are drawn for conceptual, empirical, and practical issues in the persuasion domain.
