Theories of Leadership: Four Ways to Understand Influence

Leadership theories and how a theory of leadership explains influence through traits, behavior, situations, and relationships.

The answer to a leadership problem depends on what is happening: a team may lack a capable decision-maker, clear direction, authority to act, or trust in its manager. Theories about leadership examine those different conditions. Understanding how these perspectives explain influence helps a manager choose what to investigate before changing behavior.

What Is Leadership Theory and What Does It Study?

A theory in this field explains how people influence others toward shared work and why that influence may succeed in one setting and falter in another. What a leadership theory explains depends on the outcome being studied. It proposes relationships that can be examined against evidence. What is leadership theory useful for? It gives managers a question to test against a real situation, rather than a label to apply to a person.

Theories of leadership differ in where they look for an answer: individual qualities, observable actions, the conditions around a group, or the relationship between leaders and followers. These perspectives can be combined, but each draws attention to a different source of evidence. The outcome also needs definition: meeting a deadline, developing employees, and retaining trust are related but distinct measures.

Traits: Who Is Equipped to Lead?

Trait-based leadership theories ask which relatively enduring qualities are associated with leadership. Research has examined characteristics such as personality and cognitive ability. A meta-analysis by Judge and colleagues found relationships between several personality traits and leadership, with extraversion showing a particularly consistent association in the studies reviewed.

For example, a hiring panel selecting a project manager might consider whether a candidate reliably follows through on commitments. It can ask for evidence from previous projects and check references, alongside examining relevant skills. The practical question is whether the person brings qualities suited to the responsibilities of the role.

The limitation is that an association across studies does not tell a panel how one candidate will perform in every setting. A confident speaker may gain attention while overlooking errors or silencing objections. Assess qualities alongside work samples, judgment, and the demands of the team; avoid treating a personality score as a verdict.

Behavior: What Does the Leader Do?

Behavioral approaches shift attention from characteristics to actions. The Ohio State leadership studies distinguished initiating structure, such as clarifying roles and organizing work, from consideration, such as showing concern and respect for team members. These are dimensions of behavior, not a single choice between being task-oriented and being kind.

Suppose a new team repeatedly misses handoffs. Its manager could set explicit owners and dates, then invite employees to identify obstacles in a weekly meeting. The first action structures the work; the second creates an opportunity to hear concerns. Both can be observed and adjusted, making behavior a practical subject for feedback and development.

A behavior that helps one team can burden another. Daily check-ins may support a new process but interrupt an experienced team handling routine work. Observe whether the practice improves coordination, and ask employees what information they need before making it permanent.

Situation: What Conditions Shape the Work?

Situational and contingency approaches ask how effectiveness depends on circumstances. In Fred Fiedler’s contingency model, group effectiveness depends on the interaction between a leader’s orientation and the degree to which the situation permits influence. Conditions include relations with the group, task structure, and the authority attached to the position.

Imagine an experienced manager assigned to resolve a cross-department delay but given no authority to allocate staff. Coaching the manager alone may leave the constraint untouched. Clarifying decision rights or securing a sponsor could change the conditions in which the manager works. This perspective directs attention to the assignment as well as the person.

Fiedler’s model treats orientation as relatively stable; it should not be reduced to an instruction to switch styles whenever circumstances change. Its measures have also faced methodological criticism. Use the model to examine fit and authority, while checking the actual task and relationships instead of relying on a score alone.

Influence and Relationships: How Do People Work Together?

Other approaches examine the exchange between leaders and followers. James MacGregor Burns distinguished transactional leadership, based on exchange, from transformational leadership, in which leaders and followers engage around broader purposes and development. Bernard Bass later developed a related account for organizational research; the Open University overview describes both contributions.

A transactional agreement might link a completed project milestone to an agreed reward. A transformational effort might involve explaining why a service change matters, inviting staff to challenge the plan, and supporting their development as they implement it. The first makes expectations and consequences clear; the second can help people connect their work to a shared purpose.

A compelling purpose can still be poorly chosen, and a leader’s influence can discourage dissent. Ask who benefits, whether employees can challenge decisions, and whether promises are matched by resources. Clear exchanges and shared purpose can coexist; neither removes the need to inspect results.

Choose the Question Before the Remedy

Begin with the result you need and the evidence available. If selection is the issue, ask which qualities and skills the role requires. If handoffs fail, examine actions and routines. If a capable manager cannot move work forward, inspect authority and task conditions. If commitment or candor is weak, examine the relationship and the terms of influence. Choose the question that addresses the observed difficulty, test an appropriate change, and review what happens to both the work and the people doing it.
