Personality
A person's consistent pattern of thought, emotion and behaviour.
Is personality fixed at birth?
Personality is a person's typical way of thinking, feeling and acting, fairly steady across situations; the Big Five measure it as traits, the MBTI as types.
Two equally qualified officers join a bank branch. One takes every customer complaint in her stride; the other loses sleep over each one. Their skills are the same; their personalities differ.
In plain wordsPersonality is a person's typical way of thinking, feeling and acting, which stays fairly steady across situations and over time.
Exam definitionPersonality is the sum total of ways in which an individual reacts to and interacts with others (Robbins and Judge).
Personality is unique to each person and relatively consistent. It is shaped by genetics, environment, experience and learning. At work it matters for recruitment, communication, team dynamics, leadership, motivation, job satisfaction and performance.
The Big Five (OCEAN) is the trait model with the strongest research support. Each trait is a scale, and every person sits somewhere along it.
| Trait | High scorers tend to be | At work |
|---|---|---|
| Openness | Curious, imaginative, open to new ideas | Adapt well to change and creative work |
| Conscientiousness | Organised, dependable, persistent | The most consistent link with job performance across many jobs |
| Extraversion | Sociable, assertive, talkative | Suit roles with much contact; often emerge as leaders |
| Agreeableness | Cooperative, warm, trusting | Good team members; may avoid needed conflict |
| Neuroticism | Anxious, insecure, moody | Low scorers, who are emotionally stable, cope better with stress |
An example. On a college fest committee, the highly conscientious member keeps the budget, and the extravert handles sponsors. The member high on openness designs the new event.
The Myers-Briggs Type Indicator (MBTI), developed by Katharine Briggs and Isabel Myers from Carl Jung's psychological types, sorts people into types along four dimensions. Each dimension is a two-way choice, so there are 2 × 2 × 2 × 2 = 16 types. ESTJ, for example, is extraversion, sensing, thinking and judging. It is used to understand team compatibility, leadership styles and communication preferences.
| Dimension | One preference | The other |
|---|---|---|
| E – I | Extraversion: interaction, outward energy | Introversion: reflection, solitude |
| S – N | Sensing: facts and present realities | Intuition: patterns and possibilities |
| T – F | Thinking: logic and objectivity | Feeling: empathy and human impact |
| J – P | Judging: structure and decisiveness | Perceiving: flexibility and spontaneity |
| Theory | Proponents | Core idea |
|---|---|---|
| Psychoanalytic | Sigmund Freud | Unconscious conflicts among id, ego and superego; early childhood shapes personality. |
| Behaviourist | B. F. Skinner, J. B. Watson | Personality develops through learning, conditioning and reinforcement. |
| Humanistic | Carl Rogers, Abraham Maslow | People strive for self-growth and to fulfil their potential. |
| Trait | Gordon Allport; the Big Five | Personality is a set of relatively stable traits. |
| Cognitive | Albert Bandura | Mental processes, observation, imitation and self-efficacy shape personality. |
| Biological | Hans Eysenck; Darwinian view | Personality is linked to genetics, brain chemistry and evolution. |
Don't confuse the MBTI with the Big Five. The MBTI sorts people into types: you are E or I. The Big Five scores each trait on a scale: you are more or less extraverted. Neuroticism is not an illness; it is the low end of emotional stability.
Where it breaks. The MBTI is popular in training, but its types predict job performance poorly, and people often get a different type when retested. Traits predict behaviour on average, not in every situation. Strong situations, such as strict rules or an emergency, override personality.
In practice. Use personality to place and develop people, not to label them. In hiring, a validated measure of conscientiousness tells you more than an MBTI type.
Go deeper for practitioners
Other traits exams ask about.
- Locus of control (Julian Rotter): internals believe they control what happens to them; externals credit luck or other people.
- Type A and Type B (Meyer Friedman and Ray Rosenman): Type A people are impatient, competitive and hurried; Type B people are relaxed.
- Self-monitoring (Mark Snyder): high self-monitors adjust their behaviour to the situation; low self-monitors act the same everywhere.
- Machiavellianism: pragmatic, emotionally distant, and willing to believe that ends justify means.
- Self-esteem: how far people like or dislike themselves.
A decision. You are hiring ten officers for a new branch. A vendor offers an MBTI workshop to "find the right types". Evidence favours structured interviews and a validated conscientiousness measure for selection. The MBTI may still help a team talk about how its members prefer to work.
Personality is who you are, fairly steadily, from one situation to the next.
1. Which MBTI dimension contrasts facts and present realities with patterns and possibilities?
Not quite. The answer is “Sensing and intuition”. Sensing (S) attends to facts and the present; intuition (N) to patterns and possibilities. Thinking and feeling is about how decisions are made, logic against human impact.
2. On a college fest committee, one member keeps the budget on time, tracks every receipt and never misses a deadline. Which Big Five trait does she score high on?
Not quite. The answer is “Conscientiousness”. Organised, dependable and persistent describes conscientiousness. Openness is about curiosity and new ideas, not about keeping to plans.
3. You are choosing a test to help select ten new officers. Which choice does the evidence support best?
Not quite. The answer is “A validated measure of conscientiousness”. Conscientiousness has the most consistent link with job performance. MBTI types predict performance poorly and can change on retest, so they suit team discussion, not selection.

Personality and the three qualities of nature
The Gītā describes three qualities born of nature (sattva, rajas and tamas) that bind every person and mix in different proportions, and later sorts food, work and faith by them. A modern reader may see a trait theory: stable dispositions that shape behaviour. The guṇas are a metaphysical account, not a measured personality test.
A reading offered for reflection, not a claim about what the authors meant.
“Sattva, rajas and tamas, the qualities born of nature, bind the embodied self.” सत्त्वं रजस्तम इति गुणाः प्रकृतिसम्भवाः । sattvaṃ rajas tama iti guṇāḥ prakṛti-sambhavāḥ. Bhagavad Gītā 14.5

What it addsThree qualities that mix in every person and colour food, work and faith alike.
Where they differThe guṇas are a metaphysical account of nature. Trait theories measure dispositions with tests and statistics.

Personality is consistent and acting by one's own nature
Personality is defined as a relatively consistent pattern. The Gītā observes that even a wise person acts in keeping with their own nature, and that all beings follow theirs: a person's disposition persists from one situation to the next.
“Even the wise act in keeping with their own nature; beings follow their nature.” सदृशं चेष्टते स्वस्याः प्रकृतेर्ज्ञानवानपि । प्रकृतिं यान्ति भूतानि । sadṛśaṃ ceṣṭate svasyāḥ prakṛter jñānavān api, prakṛtiṃ yānti bhūtāni. Bhagavad Gītā 3.33
About this text: Bhagavad GītāDiscuss
What it addsDisposition persists even in the wise: people act in keeping with their own nature.
Where they differThe verse asks what mere restraint can achieve, though the next verse urges not falling under the sway of likes and dislikes. Personality theory says traits are stable but allows that behaviour can be learnt and changed.

- Personality: a unique, relatively consistent pattern of thoughts, feelings and behaviour, shaped by genes, environment, experience and learning.
- The Big Five (OCEAN) score traits on scales; conscientiousness links most consistently with job performance.
- MBTI: 16 types from four two-way dimensions (E–I, S–N, T–F, J–P); popular, but weak at predicting performance.
- Theories: psychoanalytic, behaviourist, humanistic, trait, cognitive, biological.
Personality is who you are, fairly steadily.
