Ethical leadership: A review and future directions

Our literature review focuses on the emerging construct of ethical leadership and compares this construct with related concepts that share a common concern for a moral dimension of leadership (e.g., spiritual, authentic, and transformational leadership). Drawing broadly from the intersection of the ethics and leadership literatures, we offer propositions about the antecedents and outcomes of ethical leadership. We also identify issues and questions to be addressed in the future and discuss their implications for research and practice. Our review indicates that ethical leadership remains largely unexplored, offering researchers opportunities for new discoveries and leaders opportunities to improve their effectiveness.     

The loci and mechanisms of leadership: Exploring a more comprehensive view of leadership theory

Through a qualitative review of the leadership literature, we derive two fundamental principles for codifying the last century of leadership theory and research: the locus and mechanism of leadership. Our systematic review and categorization of past theories suggests that further development of the follower, collective and context loci, and the affect mechanism is needed. Building on these insights, we propose that by simultaneously considering all five loci and four mechanisms in their theories, leadership scholars can advance a more comprehensive and integrative understanding of the leadership phenomenon. We then demonstrate the potential of using the locus and mechanism framework for examining and expanding current and future leadership theory including work on shared and strategic leadership.     

The use of constructive-developmental theory to advance the understanding of leadership

Constructive-developmental theory is a stage theory of adult development that focuses on the growth and elaboration of a person's ways of understanding the self and the world. In this article we review how the constructive-developmental frameworks of Kegan [Kegan, R. (1982). The evolving self: Problem and process in human development. Cambridge, MA: Harvard University Press], Torbert [Torbert, W. R. (1987). Managing the corporate dream: Restructuring for long-term success. Homewood, IL: Dow Jones-Irwin.], and Kohlberg [Kohlberg, L. (1969). Stage and sequence: The cognitive developmental approach to socialization. In D. Goslin (Ed.), Handbook of socialization: Theory and research. New York: Rand McNally] have been applied in the theoretical and empirical literature on leadership and management. Although the literature has produced a number of propositions, the notion that a leader's order of development should impact his or her leadership effectiveness or managerial performance has generated the most research. We found mixed support for this proposition as well as a number of limitations in the research in general. To have a greater impact on the leadership field, constructive-developmental theory needs to generate more robust research, to link more clearly with on-going streams of leadership research, and to explore the contribution of aspects of the theory beyond individual order of development.     

Crisis leadership: A review and future research agenda

The past few decades have witnessed numerous crises that have drawn increasing attention to the study of crisis leadership. However, research in this field remains fragmented and existing reviews often adopt a subjective approach to identify and synthesize the findings of relevant articles. These limitations make it difficult for scholars to appreciate the progress made in the literature, to derive comprehensive and objective insights, and to forge a path ahead. This study synthesizes theoretical insights and empirical findings in the crisis leadership literature using bibliometric techniques. We first review the intellectual structure of the crisis leadership literature by conducting co-citation and bibliographic coupling analyses. We then map the major conceptual themes in the crisis leadership literature via a co-word analysis. To supplement the findings of the bibliometric analyses, we review the key methodological approaches adopted by crisis leadership researchers. Based on the integrative insights, we propose a research agenda highlighting opportunities for theoretical and methodological advancements in crisis leadership research.     

Bounded leadership: An empirical study of leadership competencies,constraints, and effectiveness

Contrary to the previous leadership theories, which focus on specific and narrow aspects of leadership such as employee characteristics, leader’s authenticity, or boundary spanning, the bounded leadership theory is a broad and complex concept. It takes simultaneously many constraints, which are related to activities on an individual, team, organization, and stakeholder level. This study applies the bounded leadership theory to analyze the leadership constraints as the mediator of the relationship between leadership competencies and effectiveness. Our findings show that leaders’ competencies are not enough for them to be effective. Specific competencies enable leaders to overcome the set of constraints and then to increase their effectiveness.     

The leadership of emergence: A complex systems leadership theory of emergence at successive organizational levels

Complexity science reframes leadership by focusing on the dynamic interactions between all individuals, explaining how those interactions can, under certain conditions, produce emergent outcomes. We develop a Leadership of Emergence using this approach, through an analysis of three empirical studies which document emergence in distinct contexts. Each of these studies identifies the same four “conditions” for emergence: the presence of a Dis-equilibrium state, Amplifying actions, Recombination/“Self-organization”, and Stabilizing feedback. From these studies we also show how these conditions can be generated through nine specific behaviors which leaders can enact, including: Disrupt existing patterns through embracing uncertainty and creating controversy, Encourage novelty by allowing experiments and supporting collective action, Provide sensemaking and sensegiving through the artful use of language and symbols, and Stabilize the system by Integrating local constraints. Finally, we suggest ways for advancing a meso-model of leadership, and show how our findings can improve complexity science applications in management.     

Military leadership: A context specific review

The purpose of this article is to review the literature on military leadership and highlight research opportunities for leadership scholars. The review uses a context specific approach and turns to a simplified version of Hunt's (Hunt, J. G. (1991). Leadership: A new synthesis. Newbury Park, CA: Sage) extended multilevel leadership model as a template to examine the many facets of military leadership. The military leadership literature is stratified into the systems, organizational, and direct levels of leadership with an examination of studies on the critical tasks and individual capabilities required at each level. Additionally, studies on organizational culture and effectiveness at each level are addressed. The article emphasizes that the military is undergoing substantial change as it adjusts to the changing nature of war and a fluid world situation. Based on trends in the military, the review concludes with several general recommendations for future research.     

Trust in leadership: A multi-level review and integration

Leaders have been argued to play a key role in determining organizational effectiveness across all levels (e.g., individual, team, unit) that exist within organizations. A key component in a leader's ability to be effective within such environments is the degree to which subordinates and co-workers trust him/her. Therefore, it is not surprising that researchers and practitioners alike are interested in identifying the mechanisms through which trust in leadership can be developed as well as those factors which moderate this relationship [e.g., Gillespie, N. A., Mann, L. (2004). Transformational leadership and shared values: The building blocks of trust. Journal of Managerial Psychology, 19, 588–607; Kouzes and Posner, 1995; Roberts, K. H., O'Reilly, C. A. (1974). Failures in upward communication in organizations: Three possible culprits. Academy of Management Journal, 17, 205–215; Whitener, E. M. (1997). The impact of human resource activities on employee trust. Human Resource Management Review, 7, 389–404]. Despite this, research that has addressed the factors that foster trust in leaders and the outcomes of this trust has been disjointed and, as yet, no comprehensive model has been presented to systematically examine these factors. Therefore, the purpose of this article will be to present an integrative model of trust in leadership.     

A meta-analytic review and future research agenda of charismatic leadership

Charismatic leadership is a critical construct that draws much attention from both academic and practitioner literatures. Despite the positive attention received by the charisma construct, some have criticized its conceptualization and measurement. These critiques have, in turn, cast doubt on what we know regarding the antecedents and outcomes of charismatic leadership. In this review, we adopt a recently developed definition of charismatic leadership and then conduct a meta-analysis of its antecedents and objective outcomes. Following an examination of 76 independent studies and 36,031 individuals, results indicate that the Big Five traits and cognitive ability vary in their association with charismatic leadership. Other findings show that dimensions of charismatic leadership predict outcomes of interest, such as supervisor-rated task performance, supervisor-rated citizenship behaviors, and group or organization performance. Several shortcomings are identified, however, in testing theoretical and methodological moderating variables. The present research ultimately provides a roadmap for new frontiers in theoretical, measurement and empirical work on charismatic leadership.     

The role of character in ethical leadership research

The study of character is a legitimate and essential topic for the analysis of leadership in organizations. We undertake three key objectives in this article to stimulate meaningful dialogue. First, a brief historical overview of the extant body of literature on character is provided. Second, working definitions of character and character-based leadership are introduced. Third, new directions for organizational scholars interested in examining the role of character-based leadership in both their research and teaching domains are suggested.     

A meta-analytic review of leadership impact research: Experimental and quasi-experimental studies

In this study we set out to conduct a comprehensive quantitative research analysis of literature reporting results on the causal impact of leadership by focusing on examining what we refer to as ‘leadership interventions.’ We defined leadership interventions as those studies where the researcher overtly manipulated leadership as the independent variable through training, assignment, scenario or other means. Our focus included both examining experimental and quasi-experimental as well as lab and field studies conducted in public and private organizations. Our goal was to address a simple question: do leadership interventions have the intended impact and if so to what degree? We conducted a comprehensive review of the published and unpublished literature and uncovered 200 lab and field studies that met our criterion as leadership intervention studies. We report here the findings of a series of meta-analyzed effects comparing the relative impact of leadership interventions across intervention types, leadership theories, and several common dependent variables. Overall, leadership interventions produced a 66% probability of achieving a positive outcome versus a 50–50 random effect for treatment participants, but this effect varied significantly when assessing moderators such as type of leadership theory.     

Seeing eye to eye: A meta-analysis of self-other agreement of leadership

The agreement between a leader's self-rating of leadership and ratings from the leader's subordinates, peers, and superiors (i.e., self-other agreement) is critical to understanding leadership, but questions remain regarding the extent to which leaders are aware of their behaviors. This meta-analysis investigates whether leader-observer agreement is influenced by type of observer and type of leadership. First, we examined the convergence (i.e., correlation) between leader- and observer-ratings along several dimensions of leadership (e.g., initiating structure, consideration, contingent reward, and transformational leadership). Our results indicated that leader-observer correlations were generally moderate and of similar magnitudes for task- and relation-oriented behaviors (with the exception of a strong correlation for contingent reward). Next, we compared leaders' and observers' mean-level ratings (i.e., Cohen's d), and found that leaders generally reported lower or similar levels of task-oriented behaviors but higher levels of relation-oriented behaviors. Last, several variables (e.g., sampling method and study purpose) moderated leader-observer convergence. Implications of these findings for research, theory, and practice are discussed.     

Qualitative research on leadership: A critical but appreciative review

This article reviews a large number of articles that derive from qualitative research on leadership that were published prior to 2004 in peer-reviewed journals. The article then goes on to examine critically but appreciatively the ways in which qualitative research on leadership is and is not distinctive. This review shows that while qualitative research has made some important contributions to certain areas of leadership, such as the role of leaders in the change process, it is sometimes not as distinctive, when compared to quantitative research, as might be supposed. The piece also examines studies that combine quantitative with qualitative research. The different ways in which the two approaches are combined is a particular emphasis in this examination. In addition, the article explores the issue of whether the corpus of research that has been accumulated by qualitative researchers can be combined with that of quantitative researchers. A central ingredient of the discussion of qualitative research is the tendency for many researchers not to build sufficiently on the studies of leadership conducted by others. It is argued that giving greater attention to this issue will allow the contributions of qualitative research on leadership to become clearer.     

Revisiting emergence in emergent leadership: An integrative,multi-perspective review

We draw attention to how and why multiple perspectives on emergence can promote leadership scholarship within the broad umbrella category of emergent leadership. Tracing the derivation of emergent leadership and related concepts since 1941, we identify four empirically derived themes: Entries, or how and where definitions were introduced and adopted; Essences, identification of key components and processes; Eclipses, where certain constructs and approaches have gained prominence over others; and Erasures, where particular lines of inquiry and methodologies have been subsumed, ignored, or removed from easy access by researchers. In critically reviewing the emergent leadership literature, we apply these themes to reveal a number of flaws that inhibit emergent leadership research, including: inconsistent measures, narrow sampling frames, tautological definitions, limited theorization, and very little attention to implications for the development of leader-follower relations. Based on this analysis, and with reference to contemporary issues, we propose an agenda for future research on emergent leadership that is informed by interdisciplinary perspectives that give prominence to emergence dynamics.     

The WICS approach to leadership: Stories of leadership and the structures and processes that support them

This article presents the WICS approach to leadership and relates it to other approaches. Effective leadership is viewed as a synthesis of wisdom, creativity, and intelligence (WICS). It is in large part a decision about how to marshal and deploy these resources. One needs creativity to generate ideas, academic intelligence to evaluate whether the idea are good, practical intelligence to implement the ideas and persuade others of their worth, and wisdom to balance the interests of all stakeholders and to ensure that the actions of the leader seek a common good. The structures and processes underlying WICS work in concert to produce and maintain stories of leadership. These stories in turn enable leaders to fulfill their mission in leading followers.     

Putting emergence back in leadership emergence: A dynamic,multilevel, process-oriented framework

The study of leadership emergence has increased substantially over the past few decades. However, due to a lack of integrative theory, we believe limited advancement has been made regarding the full process of leadership emergence. To address this concern, first, we conceptualize the leadership emergence process from a complexity perspective and define emergence as a dynamic, interactive process grounded in three principles of emergent phenomena. Second, we review how previous research has modeled leadership emergence by focusing on the content areas of the lower-level elements, the mechanisms that facilitate their emergence, and the dynamism of the process once it has emerged. Third, based on the findings from the review, we introduce a process-oriented framework of leadership emergence. Fourth, we offer propositions to guide developing and testing emergent leadership processes, and we conclude with recommendations for future leadership process research. Our hope is that by realigning the study of leadership emergence with complexity and multilevel theory, we can reorient this area to focusing more on the process mechanisms within emergence, connecting back to research progress made over 60?years ago.     

Traversing the storm: An interdisciplinary review of crisis leadership

An organizational crisis is a low-probability, high-impact event that threatens the survival of organizations and individuals, often with little warning. In response, people seek clarity, reassurance, and hope from organizational leaders. Yet, crises also vary in nature and impact (e.g., a product failure versus the COVID-19 pandemic), which presents diverse challenges to leaders and differing stakeholder perceptions. Based on a critical analysis of 69 empirical articles, we provide a comprehensive, systematic, interdisciplinary review of the crisis leadership literature. Our review utilizes the Coombs and Holladay (1996) crisis typology, where crises are categorized according to mutually exclusive attributional dimensions (i.e., internal–external and intentional–unintentional). We conduct a thematic analysis of crisis leadership within and across these four crisis categories and find that each is associated with a different leadership theme. We also examine the methodological quality and rigor of the qualitative and quantitative articles in our review. Based on our findings, we also offer suggestions to guide future crisis leadership research, and provide guidance for organizational leaders in how to respond to various crises.
