Type Approaches

The Idea Behind Type Approaches

The type approach to personality is the oldest and most intuitive way of thinking about people. Instead of measuring traits on a continuous scale (where everyone has some amount of every trait), this approach groups people into distinct categories. Each category, or "type," is meant to represent a cluster of expected behaviours that go together. The appeal is obvious: it simplifies the messy reality of human behaviour into neat, memorable labels.

However, the textbook is clear from the start that these typologies, while appealing, are too simplistic. Human behaviour is highly complex and variable, and real people rarely fit perfectly into any single box.

Ancient Typologies: Humours and Doshas

The earliest recorded attempts at personality typing come from medicine, not psychology.

Hippocrates' Humoral Theory (Greek, ~400 BCE)

Hippocrates proposed that personality was determined by the balance of four bodily fluids, or "humours." Each humour was linked to a specific temperament:

• Sanguine (blood): Cheerful, optimistic, sociable.
• Phlegmatic (phlegm): Calm, slow, unemotional, reliable.
• Melancholic (black bile): Sad, thoughtful, anxious, creative.
• Choleric (yellow bile): Irritable, ambitious, short-tempered, energetic.

Charak Samhita's Tridosha Theory (Indian Ayurveda)

In India, the ancient Ayurvedic text Charak Samhita classified people into three types based on the tridosha (three humoural elements). Each type is a person's prakriti (basic nature or temperament):

• Vata (air/space): Associated with movement, creativity, and anxiety.
• Pitta (fire/water): Associated with intensity, intelligence, and irritability.
• Kapha (earth/water): Associated with calmness, strength, and lethargy.

The Triguna System (Indian Philosophy)

A separate Indian typology is based on the three gunas (qualities) that exist in every person in different proportions. The dominance of one guna shapes a person's behaviour:

• Sattva guna: Cleanliness, truthfulness, dutifulness, detachment, discipline.
• Rajas guna: Intense activity, desire for sense gratification, dissatisfaction, envy, materialistic mentality.
• Tamas guna: Anger, arrogance, depression, laziness, helplessness.

Sheldon's Constitutional Typology (Body Build and Temperament)

In modern psychology, William Sheldon's typology is fairly well-known. He linked body build (somatotype) directly to temperament.

Jung's Introversion-Extraversion Typology

Carl Jung proposed a widely recognised typology based on where people direct their psychic energy.

• Introverts: Prefer to be alone, tend to avoid others, withdraw in the face of emotional conflicts, and are shy.
• Extraverts: Sociable, outgoing, drawn to occupations that involve dealing directly with people, and react to stress by losing themselves among people and social activity.

This is the most influential of the type approaches and forms the basis of many modern personality tests (like the Myers-Briggs Type Indicator).

Friedman and Rosenman's Type-A and Type-B Personalities

This is a more recent typology, discovered by two researchers studying psychosocial risk factors for heart disease.

Type-A Personality

• High motivation and ambition.
• Impatience and a constant sense of time urgency.
• Always in a great hurry.
• Feels perpetually burdened with work.
• Finds it difficult to slow down and relax.

Type-B Personality

• Defined simply as the absence of Type-A traits.
• More relaxed, patient, and easy-going. …
