How can you apply emotional intelligence as a leader? Let's discuss the fundamentals of emotional quotient in leadership. You'll learn how high EQ contributes to effective leadership, how to lead people and organizations with emotional intelligence, and how to develop an action plan for high-EQ management. In 1994, Harvard professor Daniel Goleman published a groundbreaking book called "Emotional Intelligence." His research showed that an executive's emotional intelligence is a greater predictor of success than their intelligence quotient, or IQ. Since Goleman's breakthrough research emerged, emotional intelligence has become a fundamental aspect of leadership improvement. The reason emotional intelligence is now considered the preferred leadership style is simple, control-based leadership isn't as effective. Leadership that lacks emotional intelligence can have damaging emotional effects on employees and their families. Control-based leadership can also have negative consequences for leaders, themselves. Managers with low EQ often receive public criticism on social media and job sites, adversely affecting their own and their company's reputation. Chances are you've worked for or known control-based leaders. Control-based leaders try to motivate by forceful means. They'll demand, yell, and threaten, using their authority to control or manipulate a situation. This approach may generate results in the short-term, but rarely improves long-term performance. Researcher and consultant Jim Collins detailed the power of the emotionally intelligent leader in his book "Good to Great: "Why Some Companies Make the Leap and Others Don't." Collins' research showed that humble leaders are more successful than controlling ones. Collins notes that leaders who positively manage employees on an emotional level have better engagement results than leaders who use intimidation or negative reinforcement tactics.
