This article is the third and final in a series prepared originally for AACRAO's Fifteenth Annual Strategic Enrollment Management Conference (SEM XV). Through this series, David Kalsbeek introduces a four-fold typology for differentiating institutional approaches to SEM. In this final reflection, he suggests that grounding this typology in Jungian theories about human cognition provides further heuristic and pragmatic value for the SEM leader. (Contains 2 tables.)
