In general, these studies simply look for significant associations between individual traits and measures of leadership effectiveness. The initial finding was that the leader characteristic was that there were no universal traits that consistently separated effective leaders from other individuals, but the final finding explains that early research considered the impact of situational variables that might moderate the relationship between the characteristic of the leader and the measure of leader effectiveness.

However, it remains one of the best-known leadership theories and offers important stories of subordinate-subordinate interaction.
