Understanding one’s leadership style is a fundamental aspect of effective management. In an era where soft skills and emotional intelligence are gaining importance, personality assessment methods for leaders have become invaluable tools for organizational development.
What is the Oldham and Morris Personality Typology?
John M. Oldham and Lois B. Morris, co-authors of the DSM-III and DSM-IV diagnostic manuals, developed a unique personality assessment tool that offers a positive, developmental approach to personality profiles. Their work, known as Your Psychological Self-Portrait, provides a basis for self-reflection and self-awareness.
Unlike many popular personality tests, the Oldham and Morris model does not categorize individuals into a single type. Instead, it presents a profile consisting of various traits, with some being more dominant than others. As noted in research published in the Journal of Occupational and Organizational Psychology, this nuanced approach to personality better reflects the complexity of human behavior in the leadership context.
Characteristics of the 14 Personality Types in Leadership
Conscientious Type
Leaders with a dominant Conscientious type exhibit a strong sense of duty, perfectionism, and adherence to rules. Studies published by Harvard Business Review show that conscientious leaders excel in environments requiring accuracy and strict adherence to procedures. However, excessive rigidity and difficulty adapting to change can limit team innovation in dynamic business settings.
Self-Confident Type
Self-Confident leaders strongly believe in their abilities and do not hesitate to take on ambitious challenges. Research indicates that “Self-confident individuals trust in themselves and their capabilities. They never doubt they are one of a kind.” Their political acumen and influence make them effective in negotiations and alliance-building. The risk, however, is a tendency toward narcissism, which can lead to ignoring others’ opinions and taking excessive risks.
Commanding Type
“Commanding individuals take control. They feel comfortable in leadership roles with authority and responsibility.” Such leaders naturally assume leadership positions, value hierarchy, and enforce discipline. Research from MIT Sloan Management Review highlights that this leadership style can be highly effective in crisis situations requiring swift and decisive actions. However, excessive control and authoritarian tendencies may stifle initiative and team engagement.
Dramatic Type
Dramatic leaders attract attention, are charismatic, and expressive. Studies on transformational leadership suggest that their ability to inspire and evoke emotions can motivate teams to achieve ambitious goals. However, mood swings and theatrical tendencies can undermine their credibility, especially among more reserved colleagues.
Vigilant Type
Vigilant leaders exhibit a heightened awareness of threats and a strong ability to anticipate problems. Their tendency to question the status quo and conduct deep analyses makes them valuable in risk management. According to research in the Journal of Managerial Psychology, this trait is particularly beneficial in high-risk industries such as finance or cybersecurity. The challenge is excessive suspicion, which may erode trust within the team.
Solitary Type
Leaders with a dominant Solitary type prefer independent work and deep concentration. Their autonomy fosters innovation and problem-solving. Research suggests this personality type is prevalent among technology and scientific leaders. However, difficulties in building interpersonal relationships and communication may hinder team management effectiveness.
Unusual Type
Unusual leaders stand out with unconventional thinking and creativity. Research conducted by MIT shows that in environments requiring breakthrough innovations, such leaders can drive revolutionary changes. However, they may struggle to communicate their vision clearly and adapt to conventional organizational structures.
Adventurous Type
“Dauntless leaders tend to flout tradition, dislike following routine, and may sometimes act impulsively and irresponsibly.” Adventurous leaders are risk-takers who challenge conventions. Studies indicate this trait is crucial for entrepreneurs and leaders in transforming industries. The downside is impulsivity and underestimating risks, leading to rash decisions.
Variable (Mercurial) Type
Variable leaders exhibit emotional intensity and adaptability. Their ability to react to changing circumstances is valuable in dynamic environments. Research in the Journal of Applied Psychology suggests this trait fosters creativity but requires significant self-regulation. The challenge is maintaining emotional stability under pressure.
Sensitive Type
Sensitive leaders display deep empathy and an intuitive understanding of others’ needs. Research published in the European Journal of Work and Organizational Psychology indicates this trait is particularly valuable in fostering inclusive and supportive workplace cultures. However, excessive sensitivity to criticism and difficulty making unpopular decisions can be drawbacks.
Devoted Type
Devoted leaders are characterized by loyalty, commitment, and a willingness to make sacrifices for their team or organization. Studies show their strong dedication to mission and values can inspire similar attitudes among team members. The risk is excessive dependence on others’ approval, which may limit decision-making autonomy.
Leisurely Type
Leisurely leaders maintain a healthy work-life balance and remain calm under pressure. Research suggests this trait helps prevent burnout, which affects 70% of leaders, according to Harvard Business Review. The challenge is a potential lack of urgency in situations requiring quick action.
Self-Sacrificing Type
Self-Sacrificing leaders prioritize others’ needs over their own, fostering a servant leadership culture. Research from the Academy of Management Journal suggests this leadership style significantly boosts employee engagement. However, neglecting personal well-being can lead to burnout.
Serious Type
Serious leaders take an analytical approach and focus on substantive aspects of work. Research indicates this trait supports rational, data-driven decision-making. However, underestimating the importance of emotional leadership and relationship-building can be a limitation.
Applying the Oldham and Morris Framework in Leadership Practice
According to research published in MIT Sloan Management Review, effective leadership in the digital age requires deep self-awareness and the ability to adapt management styles to changing circumstances. The Oldham and Morris framework offers a tool for such self-reflection.
“Integrating psychometric tests into the leadership evaluation process can significantly enhance team performance by providing valuable insights into individual strengths and potential blind spots.” Studies show organizations using psychometric assessments in leader selection and development report a 20% increase in employee engagement and reduced turnover rates.
Development Recommendations for Leaders
- Identify your dominant personality type – Understanding your personality profile is the first step toward development.
- Recognize potential risks associated with your dominant type – Every personality type has its “dark side” that may manifest under stress.
- Build teams with complementary profiles – Diverse leadership teams achieve better business results by balancing strengths and compensating for weaknesses.
- Adapt leadership style to context – The most effective leaders adjust their style to the demands of different situations.
- Invest in developing complementary traits – Consciously work on attributes that do not come naturally to your dominant type.
