Myers-Briggs Type Indicator (MBTI) | Mixed Evidence | Categorizes individuals into 16 personality types. | Lacks reliability and validity; types are inconsistent over time. | Use OCEAN model. | Big Five (OCEAN) |
Situational Leadership Model | Mixed Evidence | Leaders adapt their style based on followers' competence and commitment levels. | Limited empirical support; may oversimplify complex dynamics. | Use with care & nuance. | Adaptive Leadership, Path-Goal Theory |
Transactional vs. Transformational Leadership | Mixed Evidence | Transactional focuses on rewards/punishments; transformational aims to inspire. | Overemphasizes transformational; effective leadership blends both. | Use with care & nuance. | Full Range Leadership Model |

Theory U | Mixed Evidence | Transformation requires stages of sensing, presencing, realizing. | Lacks empirical support; impractical in high-pressure environments | Use with care & nuance. | Use as practical framework, not scientific method. |
Alternative: Design Thinking Approaches | | Charismatic Leadership Theory | Mixed Evidence | Leaders succeed due to compelling charisma motivating followers. | Charisma alone is insufficient; may suppress dissent and critical thinking. | Use with care & nuance. | Transformational Leadership | | Leaders are born not made. | Mixed Evidence | Leaders success is (mainly) due to genetics. | Genes play a role, estimates range from 20%-35% of variance, which is the largest individual contributing factor, but leaves a lot of space for other factors | | |
