Personality is the unique combination of psychological traits that characterize an individual and dictate how they interact with their environment. In a professional setting, personality is the invisible force that influences communication styles, decision-making, and stress management. Understanding these traits allows organizations to place the right people in the right roles, ensuring both employee satisfaction and high performance.
Determinants of Personality
What makes an individual who they are? Personality is generally shaped by three primary factors that interact throughout a person’s life.
1. Heredity
This refers to factors determined at conception. Physical stature, facial attractiveness, temperament, and muscle composition are often inherited. Research suggests that genetics play a significant role—roughly 35% to 50%—in determining an individual’s basic personality foundation.
2. Environment
The culture in which we are raised, our early conditioning, the norms among our family and friends, and social groups influence our development. Environment builds upon the hereditary foundation to shape specific attitudes and values.
3. Situation
While personality is generally stable, it can change in different contexts. A person who is naturally talkative and outgoing might become quiet and reserved in a formal meeting with senior executives. The situation provides the constraints that dictate which parts of a personality are displayed.
Major Personality Frameworks
Psychologists and management theorists use specific frameworks to categorize personality types into measurable components.
The Myers-Briggs Type Indicator (MBTI)
The MBTI is one of the most widely used personality assessments in the corporate world. It classifies individuals based on four dimensions:
- Extraversion (E) vs. Introversion (I): Where do you get your energy? From others or from within?
- Sensing (S) vs. Intuition (N): How do you process information? Through facts or through patterns and “gut feelings”?
- Thinking (T) vs. Feeling (F): How do you make decisions? Using logic and data or through personal values and impact on others?
- Judging (J) vs. Perceiving (P): How do you orient yourself to the outer world? Do you prefer structure or flexibility?
The Big Five Model
While the MBTI is popular for team-building, the Big Five model is often considered more scientifically rigorous for predicting job performance.
- Conscientiousness: The best predictor of job success; characterizes people who are organized, dependable, and disciplined.
- Emotional Stability: Reflects the ability to remain calm under pressure.
- Extraversion: Important for roles requiring social interaction, such as sales or management.
- Agreeableness: Essential for teamwork; characterizes individuals who are cooperative and trusting.
- Openness to Experience: Crucial for creative roles and environments undergoing significant change.
Key Personality Attributes Influencing Behavior
Beyond broad frameworks, specific traits significantly impact how an individual functions within an organizational structure.
Locus of Control
This represents the degree to which people believe they are masters of their own fate.
- Internals: Believe they control what happens to them. They are generally more motivated and seek more information before making decisions.
- Externals: Believe their lives are controlled by outside forces (luck or chance). They tend to be less satisfied with their jobs and show higher absenteeism.
Machiavellianism (Mach)
Named after Niccolò Machiavelli, this trait describes the degree to which an individual is pragmatic, maintains emotional distance, and believes that the ends justify the means. High-Mach individuals are often productive in jobs requiring bargaining skills or where there are substantial rewards for winning.
Self-Monitoring
Self-monitoring is an individual’s ability to adjust their behavior to external, situational factors.
- High Self-Monitors: Are highly sensitive to external cues and can behave differently in different situations. They are often perceived as better leaders and tend to be promoted more frequently.
- Low Self-Monitors: Cannot disguise themselves; they tend to display their true dispositions and attitudes in every situation.
The Concept of “Fit” in Organizations
Personality should not be viewed in a vacuum; its value depends on how well it aligns with the work environment.
Person-Job Fit
This theory, pioneered by John Holland, argues that satisfaction is highest and turnover lowest when personality and occupation are in agreement. For example, an investigative personality type (curious and analytical) would likely struggle in a social-service role but thrive as a researcher.
Person-Organization Fit
This focuses on whether an employee’s personality and values align with the Organizational Culture. For instance, a highly competitive individual might feel stifled in an organization that prioritizes collective harmony and team-based rewards.
