Despite the strong emotions they so often induce in others, charismatic individuals generally project unusual calmness, confidence, assertiveness, dominance, authenticity, and focus, and almost always possess superb communication and/or oratorical skills. Although the etymology of the word ("divine gift") might suggest that charisma can't be acquired, and despite the persistent inability to accurately define or even fully understand the concept, it is believed that charisma can be taught and/or learned. Others disagree with this assertion and maintain that it is an inborn trait, or acquired through growing up, and that it cannot be learned, taught, or 'gained' at will. Charisma can also be used in a negative way.
He defined charismatic authority to be one of three forms of authority, the other two being traditional (feudal) authority and legal or rational authority. According to Weber, charisma is defined thus: ...a certain quality of an individual personality, by virtue of which s/he is "set apart" from ordinary people and treated as endowed with supernatural, superhuman, or at least specifically exceptional powers or qualities. These as such are not accessible to the ordinary person, but are regarded as divine in origin or as exemplary, and on the basis of them the individual concerned is treated as a leader.
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.
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 dictator Josip Broz Tito was said to be a "charismarch" - - "ruler staying in power by charisma".
Pierre Bourdieu did not have a very different position from that of Weber's, but he stressed that a leader has charisma only if other people accept that s/he has it. Bourdieu argued that charisma usually depends on an "inaugural act" such as a decisive battle or moving speech after which the charismatic person will be regarded as such.
Theatrically, charisma can sometimes be "performed" on-stage and in films, and is encapsulated in both verbal and non-verbal communication.
