Emotional intelligence (EQ), as any set of abilities or skills has two sides, bright and dark ones. A person can employ their social abilities and high emotional skills for prosocial behavior or could use it in maladaptive ways to manipulate others to achieve self-centered outcomes. The current paper explores the relationship between emotional intelligence (EQ) and leadership through a literature synthesis. It discusses the dark side of emotional intelligence, the negative aspects of emotional intelligence. It also provides an overview of emotional intelligence and leadership concepts, and discusses the three primary constructs of emotional intelligence, their augmentation to the theory. Finally, it closes with hypothetical synopses of the leader's usage of emotional intelligence.
