The dark side of leadership: A systematic review of creativity and innovation

It is believed that workplace creativity and innovation are fostered by positive leader behaviors and positive workplace relationships and hindered by the opposite. However, some challenge this view and argue that creativity and innovation can also be fostered when employees experience what is increasingly referred to as “the dark side of leadership”. Research in this area is sparse, contradictory, and overly confusing. We provide a comprehensive systematic review of 106 empirical studies on this topic. We review research on a broad range of constructs, including abusive supervision, authoritarian leadership, narcissistic leadership, and close monitoring. As might be expected, a larger number of the articles reviewed found a negative relationship, but there are important discrepancies and details. Our review reports the main effects, summarizes the results of the mediating and moderating variables, and highlights methodological shortcomings of the previous literature. On this basis, several recommendations are made to advance this field of research.     

A systematic and critical review of research on respect in leadership

Respect is an important psychological and interpersonal phenomenon that has been included in various theoretical and empirical approaches to leadership for nearly 70 years. In this systematic and critical review article, we provide a comprehensive summary and critique of theories, definitions, measures, and empirical studies of respect in leadership. We first provide an overview of the historical and theoretical background, including the most common theories, definitions, and measures that inform empirical studies of respect in leadership. Second, we present a systematic literature review of empirical studies on respect in leadership, including a critical evaluation of research designs and statistical analyses that support claims of the validity of various conceptualizations of respect that pertain to the study of leadership. Finally, we offer a new working definition of respect in leadership, and an accompanying conceptual framework which informs a number of recommendations for future theory development, empirical research, and leadership practice.     

Search and Recombination Process to Innovate: A Review of the Empirical Evidence and a Research Agenda

The view of innovation as a process of searching and recombining existing knowledge elements has been adopted in several industries. The innovation management literature has recognized the fundamental role that search and recombination play in innovation development. However, the relevant research has provided complex, fragmented and mixed results. The authors aim to identify areas of convergence and provide directions for future research by collecting empirical evidence regarding how firms conduct the search and recombination process. They conducted a systematic literature review of 87 empirical articles in the innovation management field. The review reveals differences among the solutions adopted both within and across organizational boundaries. Specifically, it shows that the variety and diversity of knowledge elements are critical in creating breakthrough innovations. Therefore, this paper discusses how to provide access to a variety of knowledge elements. It also highlights other fundamental questions calling for further investigation, such as how scientific knowledge elements are successfully recombined and how recombination and search dynamics occur in small and medium‐sized firms. The review concludes by summarizing the current state of affairs and suggests promising directions for future investigation.     

Leading day-to-day: A review of the daily causes and consequences of leadership behaviors

A recent trend in leadership research is to explore the daily causes and consequences of leadership behaviors. As this type of research has grown dramatically in the past several years, we seek to provide a systematic review of existing empirical research that has used a daily ESM study design to examine the leadership process. In this review, we reflect on the unique and important benefits a daily perspective on leadership provides for leadership research. We also provide a systematic review of the existing research on daily leadership, discuss the methodological and theoretical aspects of the studies identified in the review, and highlight the important findings of this research. Finally, we conclude by drawing upon the reviewed articles to provide recommendations for future scholarly work. Specifically, we give recommendations that will both broaden scholars' understanding of the daily leadership process as well as deepen understanding.     

Visualizing the landscape and evolution of leadership research

Complementing prior quantitative and qualitative reviews of the leadership literature, we conduct a bibliometric analysis of leadership articles. Our bibliometric review provides a different perspective by portraying the landscape and developmental trajectory of leadership research over time via co-citation and co-occurrence analyses. Using a scientific visualization tool CiteSpace and 6528 leadership works collected from the Web of Science database from 1990 to 2017, we detect and visualize the landscape of leadership research and track how this landscape has evolved. After mapping the landscape, we discuss the insights gleaned from our bibliometric review, with a focus on open questions, future research directions, and implications. In doing so, our review provides readers with a systematic understanding of the development of the leadership field and a roadmap to spark leadership research and move this literature forward.     

Embodying who we are: Leader group prototypicality and leadership effectiveness

Leadership is a process enacted in the context of a shared group membership, and leadership effectiveness is contingent on followers' perceptions of the leader as a group member. Addressing this role of group membership, the social identity theory of leadership puts leader group prototypicality, the extent to which the leader is perceived to embody group identity, center-stage in leadership effectiveness. I review empirical research in leader group prototypicality, concluding there is a robust empirical basis for the key propositions of the social identity theory of leadership. I also identify newer developments that extend and enrich the social identity analysis of leadership, including attention to the roles of uncertainty, leader fairness, leader–follower relationship, leader self-perceived prototypicality, and leadership of creativity and innovation.     

A meta-analysis of humble leadership: Reviewing individual,team, and organizational outcomes of leader humility

Humility is a concept grounded in a self-view that something greater than oneself exists. A multitude of disciplines to date have sought to understand how humility impacts leaders, as well as the individuals, teams, and organizations they lead. Despite overlapping research questions, methodologies, and empirical contexts, studies examining leader humility have developed largely in isolation with little overlap between fields. This has created a fundamental divide between micro and macro researchers who suggest that humility is conceptualized as both a mutable behavioral state and a stable leader trait, respectively. We provide a systematic review of research on leader humility at multiple organizational levels of analysis to provide linkages across disciplinary and theoretical divides. We couple our systematic review with a meta-analysis of 212 unique studies, identifying 99 estimates for the relationships between leader humility and numerous individual, team, and organizational variables. Among all variables, we find humble leadership most strongly predicts followers’ satisfaction with the leader and the leaders’ participative decision making. We also find humble leadership does not affect their own job performance or the performance of organizations, but improves the performance of their followers and teams. Building on our results, we call for research across academic disciplines.     

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.     

State-of-the-science review of leader-follower dyads research

Despite its importance in multilevel research, the dyad level of analysis has been known as the most poorly understood level. Suggestions have been made recently in terms of levels alignment issues and methodologies to enhance the understanding of dyadic phenomena. Given recent remedies for dyads research and that the leader-follower dyad is generally considered the key dyad in organizations, we conducted a comprehensive review of the current state of leader-follower dyads research to assess what we know and how much we know about leader-follower dyads research conducted at the dyad level. Specifically, we summarized empirical studies that focused on leader-follower dyads that used data collected on the same variables from both dyadic partners. This review involved coding studies of these “pure” leader-follower dyads based on several dyadic theories (e.g., vertical dyad linkage, individualized leadership, leader-member exchange, leader-follower congruence) and multiple analytic methods (e.g., multilevel modeling, polynomial regression, WABA) that dealt with leader-follower dyads directly. Based on the results, this review generated a nomological network of constructs for understanding leader-follower dyads and to provide suggestions for future leader-follower dyads research.     

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

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.

Management innovation: A systematic review and meta-analysis of past decades of research

Managerial innovation has gained increased popularity in research and practice because of its positive effects on organisational renewal and performance. Regardless of the growing number of studies on management innovation, there is still a lack of research that integrates and synthesises this body of knowledge. This study undertakes a systematic review and meta-analysis of the literature to gain insight into existing empirical studies on management innovation. Our content analysis and review of 66 studies from 1981 to 2017 analyses the trends and background of research into management innovation. In addition, we develop a model of management innovation grounded in selected theoretical lenses to advance our understanding of the different drivers, moderators, mediators and outcomes of management innovation. Results of the meta-analysis show that management innovation is positively related to organisational size (r_c = .282), knowledge management (r_c = 0.608), organisational learning (r_c = 0.692), firms’ overall performance (r_c = 0.393), and financial performance (r_c = 0.269). Finally, we have identified several research gaps and provided a future research agenda in the context of managerial innovation.     

In search of missing time: A review of the study of time in leadership research

Many studies describe leadership as a dynamic process. However, few examine the passage of time as a critical dimension of that dynamism. This article illuminates this knowledge gap by conducting a systematic review of empirical studies on temporal effects of leadership to identify if and how time has been considered as a factor. After synthesizing key findings from the review, the article discusses methodological implications. We propose that a computational science approach, particularly agent-based modeling, is a fruitful path for future leadership research. This article contributes to leadership scholarship by shedding light on a missing variable (time) and offering a novel way to investigate the temporal, dynamic, emergent, and recursive aspects of leadership. We demonstrate the usefulness of agent-based modeling with an example of leader-member exchange relationship development.     

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.     

Natural experiments in leadership research: An introduction,review, and guidelines

Endogeneity is a serious challenge for leadership research. To overcome the problem, researchers increasingly rely upon experimental designs, such as laboratory and field experiments. In this paper, we argue that natural experiments — in the form of standard natural experiments, instrumental variable, and regression discontinuity designs — offer additional opportunities to infer causal relationships. We conduct a systematic, cross-disciplinary review of 87 studies that leverage natural experimental designs to inquire into a leadership topic. We introduce the standard natural experiment, instrumental variable, and regression discontinuity design and use topic modeling to analyze which leadership topics have been investigated using natural experimental designs. Based on the review, we provide guidelines that we hope will assist scholars in discovering natural exogenous variations, selecting the most suitable form of natural experiment and by mobilizing appropriate statistical techniques and robustness checks. The paper is addressed to leadership and management scholars who aim to use natural experiments to infer causal relationships.     

Charismatic,ideological, & pragmatic (CIP) model of leadership: A critical review and agenda for future research

Criticisms of the dominant leadership perspectives in the literature are increasing and, as such, a growing number of scholars are calling for more complex and conceptually sound theories of leadership. With a multi-faceted perspective on effective leadership, detailed conceptual underpinnings, and increasing body of empirical support, the Charismatic, Ideological, and Pragmatic (CIP) model of leadership has the potential to address many of these concerns and substantively contribute to our understanding of effective leadership. Despite such advantages, however, wide scale proliferation of the model remains elusive. As such, this effort provides the first comprehensive review of the CIP model to analyze its potential to expand our understanding of leadership in science and practice. In doing so this review frames and organizes the existing CIP literature, identifies key strengths of the model, addresses key limitations of the model, and outlines future research opportunities that would benefit from adopting a CIP perspective.     

Leadership, self, and identity: A review and research agenda

This article reviews empirical research on the role of follower self-conception in leadership effectiveness, and specifies an agenda for future research in this area. The review shows that several aspects of follower self-conception (i.e., self-construal, self-efficacy, self-esteem, and self-consistency) may be affected by leadership, and may mediate the effects of leadership on follower behavior. There also is consistent evidence that follower self-construal moderates the impact of leadership on follower attitudes and behavior. Two key themes for future research are defined. First, future research should focus on the development of theory about the role of relational self-construal in the leadership process. Second, it seems particularly valuable to develop theory about the interplay of different aspects of follower self-conception in leadership effectiveness, including the interactive effects of these aspects of self. Working backwards from these theoretical models of follower self-conception, specific leader behavior relevant to these aspects of self should then be identified.     

Advances in leader and leadership development: A review of 25 years of research and theory

The development of effective leaders and leadership behavior is a prominent concern in organizations of all types. We review the theoretical and empirical literature on leader and leadership development published over the past 25 years, primarily focusing on research published in The Leadership Quarterly. Compared to the relatively long history of leadership research and theory, the systematic study of leadership development (broadly defined to also include leader development) has a moderately short history. We examine intrapersonal and interpersonal issues related to the phenomena that develop during the pursuit of effective leadership, describe how development emerges with an emphasis on multi-source or 360-degree feedback processes, review longitudinal studies of leadership development, and investigate methodological and analytical issues in leader and leadership development research. Future research directions to motivate and guide the study of leader and leadership development are also discussed.     

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.     

Follower transformation as the linchpin of transformational leadership theory: A systematic review and future research agenda

Transformational leadership theory represents a cornerstone in leadership research. Despite an impressive empirical record highlighted by both the breadth of its nomological network and magnitudes of effects, scholars raise serious construct and content validity concerns. In this article, we address a remarkable oversight in the transformational leadership literature. Few studies have assessed the theory assumption that the positive individual, group, and organizational effects of transformational leadership are due to the transformation of followers in specific and enduring ways. We offer a systematic review of empirical evidence related to follower transformation as the conceptual foundation of transformational leadership theory. Findings from this review highlight the radical leap in the evolution of transformational leadership theory from nascent phenomena to mature paradigm. Calling for a return to nascent and intermediary phases of theory development, we conclude with a research agenda aimed at creating a stronger theory, better measures, and more actionable leadership models.
