The trait theory expands further on this conjecture, by concentrating on the personal characteristics of the leader. The theory, which until the mid-1940s formed the basis of most leadership research, cited traits believed to be characteristic of leaders, the list of which grew in length over the years, to include all manner of physical, personality and cognitive factors, including height, intelligence and communication skills. However, few traits emerged to conclusively differentiate leaders from non-leaders. The traits an individual has may, increase the probability that a person will become a leader, though whether such leadership is guaranteed, is uncertain. Nevertheless, it can be seen to be true that some people are more likely than others to assume leadership positions.

As interest in the trait approach to leadership declined, researchers focused their attention on the leader's actions rather than their attributes, which led to the emergence of the behaviourist theories. The most widely publicized exponent of this approach was Robert Blake and Jane Mouton's Managerial Grid, which attempted to explain that there was one best style of leadership, by various combinations of two factors regarding a concern for production and people.

Developing such abilities and skills requires no position of authority but does require commitment to self, commitment to the organization and its employees, action, and thoughtful, on-going self-assessment. Such a program of personal development, ideally begun as a part of the formal education process, can assist significantly in learning how to influence others, up, down, and across the organization. Thus, one can learn how to become what Cohen (1990) has called an "uncrowned leader," a person who exerts influence over others but lacks positional authority.
