““the Great Man theory (that leaders are born not made, the concept closest to our idea of some people, such as Rick Rescorla, having the ‘right stuff’); trait theory (a derivative of Great Man theory, which posits that leaders are distinguished by the traits or attributes they display, such as integrity and trustworthiness); psychoanalytic theory (Freud’s idea that all social groups are representations of the family); charismatic leadership (in which a figure attracts followers purely on the basis of personality); behavioural theory (that effective leadership results from certain behaviours); situational theory (that the way leadership is executed depends on the situation); contingency theory (an expansion of situational theory, which, in addition to situation, takes account of variables such as the kind of task for which leadership is required and how much power the leader has); transactional versus transformational leadership theory (which contrasts a fairly conventional style of leadership with a more visionary, inspirational style); distributed leadership theory (which eschews a strict hierarchy for a more fluid model, in which leadership roles are shared naturally rather than being formally assigned); and servant leadership theory, in which leadership is carried out purely for the benefit of the group, often at cost to the leader himself.””
