The Science of Leadership: A Theoretical Model and Research Agenda

Abstract

I review the empirical literature on leadership, focusing on papers published since 2010. To do so, I introduce a framework composed of two features: whether theories ( a) involve the study of leaders or leading (i.e., the person versus the process) and ( b) conceptualize leadership as a cause or a consequence (i.e., an independent versus dependent variable). This framework can enable future research to accumulate in a more programmatic fashion and help scholars determine where their own studies are located within the landscape of leadership research. I end the review by critically evaluating existing work, arguing that the most popular subcategory of leadership research—lumped conceptualizations of leading, in which scholars examine multiple leader behaviors within a single construct—has significant limitations and may need to be replaced by a greater focus on split conceptualizations of leading, wherein scholars isolate single leader behaviors. Expected final online publication date for the Annual Review of Organizational Psychology and Organizational Behavior, Volume 9 is January 2022.
