PART 5: Personality
Meaning, traits and types, what shapes personality, development and major theories
In every office there is the person who talks to everyone, the one who needs a quiet corner, the one who plans everything in advance and the one who thrives on last-minute chaos. Nobody is āwrongā; they are just different. What makes each of them behave in a consistent, recognisable way is personality. It explains why the same situation brings out very different reactions in different people.
5.1 Introduction to Personality
The word personality comes from the Latin persona, the mask worn by actors in ancient Roman theatre. Today it means the inner patterns behind the āmaskā we show the world.
- Gordon Allport (1937): personality is the dynamic organisation within the individual of those psychophysical systems that determine his unique adjustments to his environment.
- Robbins: personality is the sum total of ways in which an individual reacts to and interacts with others.
In simple words: personality is the unique and relatively stable pattern of thoughts, feelings and behaviours that makes a person who they are.
Why does personality matter in organisations?
- It helps predict how people will behave in different jobs and situations.
- It helps in selection, placement and team building.
- It affects leadership style, stress handling and teamwork.
- It supports personājob fit and personāorganisation fit.
5.2 Attributes (Characteristics) of Personality
| Attribute | Meaning |
| Unique | Every personās personality is different, even identical twins differ in some ways. |
| Organised | The traits are linked into a pattern, not a random collection. |
| Relatively stable | It stays fairly consistent across time and situations, though it can change slowly. |
| Dynamic | It keeps developing through experience and learning. |
| Psychophysical | It involves both mind (thoughts, feelings) and body (physical make-up). |
| Goal-directed | It guides how a person adjusts to the environment and pursues goals. |
| Influenced by environment | Family, culture and experiences shape its expression. |
Personality traits
A trait is an enduring characteristic that describes a personās behaviour, for example shy, aggressive, ambitious, loyal, lazy or timid. Allport divided traits into cardinal (one dominating trait that shapes a whole life, rare), central (the 5ā10 core traits we use to describe someone) and secondary (less consistent, situation-based preferences).
5.3 Types of Personality
A. Introvert and extrovert (Carl Jung)
| Extrovert | Introvert | |
| Energy source | Gains energy from people and activity. | Gains energy from solitude and reflection. |
| Style | Outgoing, talkative, expressive. | Reserved, thoughtful, listens before speaking. |
| Work fit | Sales, public relations, team leadership. | Research, analysis, writing, design. |
Most people are somewhere in between (sometimes called ambiverts).
B. Type A and Type B (Friedman and Rosenman)
| Type A | Type B |
| Always in a hurry, impatient with delay. | Relaxed, patient, takes things easy. |
| Highly competitive and achievement-driven. | Not easily upset by time pressure. |
| Does several things at once. | Works steadily, enjoys leisure. |
| Higher stress levels and health risks. | Lower stress. |
C. The Big Five model (OCEAN)
The most widely accepted modern personality model says that personality can be described on five broad dimensions. Remember it as OCEAN.
| Dimension | High scorer | Low scorer | Work relevance |
| Openness to experience | Curious, imaginative, creative. | Conventional, prefers routine. | Innovation, adaptability to change. |
| Conscientiousness | Organised, dependable, disciplined. | Disorganised, careless. | Best single predictor of job performance across most jobs. |
| Extraversion | Sociable, assertive, energetic. | Reserved, quiet. | Sales, leadership, networking. |
| Agreeableness | Cooperative, trusting, warm. | Cold, critical, antagonistic. | Teamwork, customer service. |
| Neuroticism (opposite: emotional stability) | Anxious, insecure, moody. | Calm, secure, steady. | Stress handling, high-pressure roles. |
D. Myers-Briggs Type Indicator (MBTI)
MBTI classifies people on four dimensions: Extraversion/Introversion, Sensing/Intuition, Thinking/Feeling and Judging/Perceiving, producing 16 types. It is very popular in training, but researchers criticise its reliability and its use for hiring decisions. Treat it as a tool for discussion and self-understanding, not as a final verdict.
E. Other personality traits that matter at work
| Trait | Meaning | Effect at work |
| Locus of control (Rotter) | Internals believe they control events; externals believe luck or fate does. | Internals tend to take initiative and responsibility. |
| Self-efficacy (Bandura) | Belief in oneās own ability to succeed at a task. | Higher self-efficacy leads to more effort and persistence. |
| Self-esteem | How much people like or value themselves. | Affects confidence, risk-taking and reaction to criticism. |
| Self-monitoring (Snyder) | Ability to adjust behaviour to the situation. | High self-monitors adapt well and often become leaders. |
| Machiavellianism | Pragmatic, keeps emotional distance, believes ends justify means. | Can succeed in jobs rewarding manipulation, but can harm trust. |
| Narcissism | Arrogance, need for admiration, sense of entitlement. | May appear charismatic, but often poor team players. |
| Risk-taking | Willingness to take chances. | Useful in entrepreneurship and trading; risky in safety-critical jobs. |
| Proactive personality | Takes initiative and acts to change the environment. | Often higher performance and career success. |
F. The Indian view: the three Gunas
Indian philosophical thought, notably the Bhagavad Gita, describes three gunas (qualities) present in everyone in different proportions: Sattva (purity, balance, knowledge), Rajas (activity, passion, ambition) and Tamas (inertia, ignorance, dullness). Some Indian management writers use this as a framework for understanding personality and leadership. It is a philosophical perspective, not an experimental model like the Big Five.
5.4 Factors Affecting (Determinants of) Personality
| Factor | Explanation | Example |
| Heredity (biological factors) | Genes shape physical features, temperament and some traits. Studies of twins raised apart (such as the Minnesota study) show a substantial genetic influence. | Two siblings inheriting a calm temperament. |
| Family and home | Parentsā values, parenting style and early upbringing. | Children from supportive homes often develop higher confidence. |
| Culture and society | Norms, traditions, religion and social expectations. | Collectivist cultures encourage cooperation and respect for elders. |
| Education and school | Teachers, peers and learning experiences. | A good teacher builds a studentās self-belief. |
| Situation | Specific circumstances can bring out different sides of personality. | A shy person may speak boldly on a subject they know deeply. |
| Life experiences | Successes, failures, travel, work, relationships. | A tough first job builds resilience. |
| Physical environment | Climate, living conditions, resources. | Growing up in a small town versus a metro. |
Modern psychology treats it as nature plus nurture: heredity sets the base, and environment and experience shape how it develops.
5.5 Personality Development
Personality development is the process of improving a personās traits, habits, attitudes and skills so that they can function better personally and professionally. Personality is relatively stable, but it can be improved with deliberate effort. Erik Eriksonās theory suggests that people go through eight psychosocial stages from infancy to old age, each with its own challenge (for example, trust vs mistrust in infancy, identity vs role confusion in adolescence).
How can personality be developed?
- Know yourself: use tools like the Johari Window and honest self-reflection to understand strengths and gaps.
- Ask for feedback from teachers, colleagues and friends, and accept it without defensiveness.
- Build communication skills: speaking, listening, writing, body language.
- Develop emotional intelligence: manage emotions, understand others.
- Set goals and form positive habits: punctuality, discipline, regular reading.
- Learn continuously: courses, mentors, new challenges.
- Practise confidence-building: take small public-speaking or leadership opportunities, and learn from mistakes.
- Look after health and stress: sleep, exercise, hobbies, meditation.
- Seek professional help (counselling, coaching) when needed.
Real-world spotlight: the MBA classroom
MBA programmes use group projects, presentations, case discussions and internships not only to teach theory, but to develop personality: confidence in speaking, teamwork, leadership and the ability to handle criticism.
5.6 Theories of Personality
A. Trait theories
- Allport: cardinal, central and secondary traits (see above).
- Cattell: identified 16 source traits and developed the 16PF questionnaire.
- Eysenck: described personality on three dimensions: extraversionāintroversion, neuroticismāstability, and psychoticism.
- Big Five (Costa and McCrae, Goldberg): OCEAN, now the dominant trait model.
Idea: personality can be described and measured through a set of stable traits. Criticism: traits describe, but do not fully explain, and behaviour can vary by situation.
B. Psychoanalytic theory (Sigmund Freud)
Freud argued that much of behaviour is driven by unconscious motives. Personality has three parts:
| Part | Principle | Simple meaning |
| Id | Pleasure principle | Instinctive wants: āI want it now.ā |
| Ego | Reality principle | The sensible mediator: āLet us find a realistic way.ā |
| Superego | Morality principle | The conscience: āThat is not right.ā |
Freud also described levels of mind (conscious, preconscious, unconscious) and defence mechanisms such as denial, projection and rationalisation. Example: an employee who blames the manager for his own poor performance is using projection or rationalisation. Criticism: hard to test scientifically and heavy emphasis on childhood and sexuality.
C. Humanistic theories (Carl Rogers, Abraham Maslow)
Humanistic psychologists believe people are basically good and have an inner drive for growth and self-actualisation. Rogers emphasised the self-concept and the importance of unconditional positive regard (acceptance), which helps a person become the best version of themselves. At work this translates to supportive environments, autonomy and trust.
D. Social learning and cognitive theory (Albert Bandura)
Bandura said we learn personality by observing and imitating others and by our beliefs about our own abilities (self-efficacy). He proposed reciprocal determinism: personality, behaviour and environment all influence each other. Example: a new employee copies the confident presentation style of a respected senior and gradually becomes more confident.
E. Type theories
Type theories sort people into categories. Examples include Hippocratesā four temperaments (sanguine, choleric, melancholic, phlegmatic), Sheldonās body types (endomorph, mesomorph, ectomorph), Jungās introvert/extrovert, and Friedman and Rosenmanās Type A/B. They are simple and easy to remember, but real people rarely fit neatly into one box.
