Authentic Leadership: 20-Year Review Editorial, Andrei A. Lux, Kevin B. Lowe

Research outputs 2022 to 2026

Our field has reached a critical juncture. Authentic leadership, which once promised to illuminate how leaders inspire and influence through genuine actions, has become mired in conceptual ambiguity and ideological bias. Much of the research is based on evaluations of behaviour conflated with antecedents and outcomes, presuming an oversimplified, positive view of authenticity. To advance, we must refocus on what authentic leaders actually do – their discrete behaviours – as signals of leadership. In this editorial, we redefine authentic leadership through signalling theory to address unresolved critiques and provide a platform for meaningful progress. We then summarise and synthesise the …
