Observing leadership as behavior in teams and herds - An ethological approach to shared leadership research

Both Shared Leadership Theory and evolutionary theories of leadership emphasize the role of team-level patterns of influence on team or group success. Yet, most of the empirical work on the effects of shared leadership assesses the concept through patterns of subjective perceptions of leadership and behavior. Although these studies give us important insights, subjective perceptions of leadership are prone to biases. In this paper, we draw on evolutionary theories of the development of leadership in groups and argue that group-level patterns of observable behavior have a direct effect on team outcomes above and beyond patterns of leadership and behavior perceptions. On the basis of a brief review of ethological assessment methods of leadership in animal groups, we derive implications for team leadership research methods to test hypotheses on team-level influence patterns and performance. Emphasizing the role of influence in terms of interpersonal behavior we formulate implications for the assessment and analysis of verbal and nonverbal behavior in teams. Finally, we discuss how technological advances may be utilized to promote behavioral observations in team leadership research.
