Impacts of Leader Humility Between Authority and Trustworthiness on Compliance: Tests of Three-Way Interaction

This study aims to examine how leader humility affects the relationship between authority and trustworthiness, and its effect on subordinate compliance. This study further addresses the reliability and validity issue to advance the measurement of humility; 300 participants consisting of leader-subordinate dyads of 50 leaders and 250 subordinates contributed to the data collections. This study found that both trustworthiness and authority have impact on subordinate compliance. Through three-way moderating analysis, this study further revealed that a leader's high humility, along with high trustworthiness under high authority results in the highest compliance, whereas a leader's high humility combined with low trustworthiness under low authority leads to the lowest compliance. Moreover, although a leader's personal background showed no relationship with the degree of leader humility, divergent combinations of leader-subordinate backgrounds were found to affect the degree of humility. Based on our findings, we propose that to effectively increase compliance, leader humility must be viewed as a strength when combined with high trustworthiness in high authority situations. This study may prompt future research in exploring humility in the context of virtue versus power, and the effects of humility in leadership. The implications of these findings for both theory and practice are also discussed.
