Abstract: This article explores the distinction between authentic and self-serving applications of emotional intelligence (EI) in leadership. While EI refers to the ability to understand and manage emotions, leaders utilize this competency in different ways - some authentically to connect with others, others more manipulatively for self-gain. The research presented finds authentic EI fosters high-trust, collaborative cultures and performance through empathizing with stakeholders, while self-serving EI breeds toxicity and disengagement. Examples of leaders demonstrating authentic EI through care, vulnerability and accountability are provided, such as Tim Cook and Brené Brown, contrasted with examples of self-interested leaders like Adam Neumann and Elizabeth Holmes who undermined culture. The article offers recommendations for developing authentic EI through self-reflection, active listening, generous feedback and genuine interest in others. Overall, leaders are advised to consider whether their EI stems from integrity or self-interest, as authentic application anchored in understanding people empowers thriving organizational cultures.
