The trait theory of leadership suggests that effective leadership stems from inherent personality traits and characteristics that produce consistent behavioral patterns. This theory is among the first investigations into the nature of good leadership.
The trait theory of leadership finds its roots in the "great man" theory of leadership, first proposed by Thomas Carlyle in the mid-1800s. Carlyle believed that history is shaped by extraordinary leaders with inherent leadership abilities. Inspired by this theory, early leadership research primarily focused on heritable traits.
Carlyle's theory was based on the following rationale:
Even today, books and articles continue to highlight various characteristics considered crucial for great leadership, suggesting that leadership is predestined in certain individuals.
Over time, psychologists have debated the trait-based theory of leadership. In the 1940s to 1970s, Ralph Melvin Stogdill proposed that leadership results from the interaction between the individual and the social situation, rather than a fixed set of traits.
In the 1980s, James M. Kouzes and Barry Z. Posner proposed that credibility is a key indicator of leadership skills, characterized by traits such as honesty, forward-thinking, inspiration, and competence.
The specific list of leadership traits may vary, but a recent study outlined behavioral traits that distinguished lower-level supervisors from higher-level supervisors.
Researchers found that the traits most commonly associated with great leadership include:
Early leadership studies focused on differences between leaders and followers, assuming that leaders would display more leadership traits. However, research showed relatively few traits could distinguish leaders from followers. While leaders often have strong communication skills, extroversion, self-confidence, and height, these differences are typically minor.
The trait-based theory has its shortcomings; while proponents suggest certain traits characterize strong leaders, those with these traits don't always become leaders. Some believe this is due to situational variables where leadership skills only emerge when opportunities arise, such as wars or political crises.
Others have taken a contingency approach to leadership, suggesting that specific traits may be more effective in some situations than others. Opinions vary on which traits predict success and to what extent.
A contentious belief is that certain individuals lack the traits to become leaders. This view overlooks social and economic inequities that limit or erase a person's potential to lead.
It also disregards the changing economy and the redefinition of leadership in the era of online and offline connections. As outlets for leadership evolve (e.g., social media and e-commerce), the traits needed for success differ due to the reduced number of intermediaries. In this realm, influencing others may be more critical than leading.
While various traits are often associated with effective leadership, few leaders possess all of these qualities. Generally, a strong leader will have many of these qualities.
However, aspects of the situation also play a vital role in determining whether individuals can lead effectively. Often, it is the interaction between these traits and the situation that shapes leadership quality.
