Addressing psychological literature's deficiency in research on the early development of leaders in everyday life (e.g., leaders in the workplace, leaders in social settings, leaders in organizational settings), this study assumed that central psychological capacities required for such leaders can be predicted and explained by J. Bowlby's (1969) attachment theory concerning developmental processes in infancy. The authors administered a series of questionnaires to 402 participants. The authors analyzed data by using structural equation modeling. Findings indicate a potential-to-lead construct that forms in infancy. The results fully supported the authors' main arguments: that secure attachment style influences the potential to lead and that this capacity is essential for leadership as measured by leadership ranking.
