Personality and charm, not external power or authority, are what count most for the "it factor."
Defining what makes a good leader is hard. Great leaders have certain qualities that are difficult to identify and pin down, begging the question: Why do people follow them? Often, the answer has to do with an indescribable “it” factor -- a charisma that attracts others to them.
While charisma is something that seems innate to leaders like the Rev. Martin Luther King, Jr., Indian leader Mahatma Gandhi and former president Barack Obama, Professor Richard Wiseman of the University of Hertfordshire told Forbes that charisma is 50 percent innate and 50 percent trained.
