Over the past thirty years, leadership studies have expanded considerably – spanning transformational, transactional, ethical, authentic, and servant leadership perspectives. Yet individual studies often produce mixed or context-specific findings. Meta-analysis provides a powerful solution by combining hundreds of studies and perspectives of thousands of respondents. By statistically integrating results across many independent studies, meta-analysis corrects for sampling error and measurement bias, estimates better understanding of effect sizes (strength of relationships between variables), and identifies patterns that are not visible in single studies. In short, it transforms scattered evidence into cumulative knowledge.
This webinar reviews three decades of meta-analytic research to identify and clarify what matters in leadership. It will examine which leadership approaches most strongly predict performance, engagement, well-being, and other outcomes of interest. These insights sharpen theory, guide evidence-based practice, and inform leadership development investments with greater precision and confidence. Participants will gain a clearer understanding of how meta-analytic findings inform debates, challenge assumptions, and support more robust understanding of leadership dynamics and effectiveness.
The session will focus on the following key questions:
- How meta-analysis strengthens evidence and resolves conflicting findings in leadership research.
- Which leadership approaches show the most robust, replicable effects across contexts.
- How to translate meta-analytic evidence into leadership development and effectiveness
