Let’s agree about nice leaders: A literature review and meta-analysis of agreeableness and its relationship with leadership outcomes

Abstract

In this study, we draw from 22 years of research in leadership to investigate the ambiguous relationship between the personality trait agreeableness and leadership. First, we conduct a comprehensive review of the leadership literature to build a foundational understanding of leader agreeableness that includes providing a broad definition for agreeableness, identifying emerging trends, and proposing an agenda for future research. Second, using the literature review as our theoretical foundation, we conduct a meta-analysis from the same body of literature to quantitatively decompose the relationship between leader agreeableness and leadership emergence and effectiveness. We also hypothesize and test the contextual moderating effects for gender, leadership level, and cultural context (as reflected by individualism-collectivism). Collectively, our findings provide a framework for future research on leadership agreeableness and support the notion that nice (highly agreeable) leaders can emerge as effective leaders.
