Answer:
The scientific concept or theory behind great leadership is the "trait theory of leadership". This theory proposes that individuals are born with certain traits that help them to become leaders, such as intelligence, charisma, problem-solving skills, and ambition.
One example of this concept is exemplified by the ancient Greek leader Alexander the Great. Alexander was highly intelligent, ambitious, and triumphant in achieving his goals. He was also able to build and motivate a strong team and continuously learned from his experiences. His passion and determination to succeed motivations, as well as his ability to always come up with a solution in difficult situations, made him an admirable leader.
This same principle can be applied in today's workforce. For example, employees often look for leaders who are passionate about the company's mission, have excellent problem-solving skills, are able to motivate their teams, and are confident in their decisions. Such traits enable leaders to foster trust and loyalty from their employees, which is essential for any organization to experience success.
In conclusion, the trait theory of leadership proposes that individuals possess certain traits that enable them to be successful leaders. Alexander the Great is a historical example of this concept, and it can still be applied today in the modern workplace.
