In this monograph, instead of reviewing or meta-analyzing the literature in the field of adolescent risk, Reyna and Farley provide what the field needs much more—a metatheoretical reorientation. Two of their major metatheoretical choices are, I think, exactly right: the emphasis on a broad theory of rationality and the emphasis on dual-process models of cognition. Reyna and Farley rightly see that assumptions about rationality partly determine the scientific theories that dominate the field at any given point in time.
