Here is a sort of interesting quote from Wikipedia:
Psychology and sociology
The study, recognition, and development of charisma in individuals is of particular interest to sociologists/psychologists, popular (usually national) politicians, public speakers, actors, movie-stars/movie-producers, casting directors, pop-music stars, trainers/coaches targeting the upper-echelons of the business community (CEOs), and academics or others involved in leadership studies or leadership development, among others.[2] Media Scientists are studying the question of how you can stage charisma in radio and television.[3]
[edit] The dark side of charisma
Wiki letter w.svg This section requires expansion.
In some cases highly-extroverted and brutally controlling charismatic leaders have used their personal charisma in extremely destructive and damaging ways throughout human history, for example, Adolf Hitler and Jim Jones. Yugoslav communist leader Josip Broz Tito was said to be a “Charismarch” – “ruler staying in power by charisma”[citation needed].
