Follower and leader cognitions play critical roles in many organizational phenomena. In this review, we report and reflect on a decade of cognitive leadership research. Following a brief introduction, the review is divided into two sections-one devoted to individual and dyadic cognition, and the other to collective cognition. We identified three central themes for each section. For individual and dyadic cognition, we identified metacognitive processes and leadership, implicit leadership theories (ILTs), and network based models of ILTs as central themes. For collective cognition, we identified charisma, organizational performance and sensemaking, and transformation and change as central themes. Our goal in this review was to uncover important underlying assumptions of selected studies to illuminate more clearly the path of cognitive leadership research over the past 10 years and its potential paths over the next ten years.
