Type Theory> Jung's Type Theory

Carl Gustav Jung, a prominent Swiss psychiatrist, developed a personality typology that has greatly influenced psychology. His theory classifies people based on how they direct and perceive their energy and information—primarily dividing personalities into Introverts and Extroverts, along with four psychological functions.

Jung proposed that the psyche consists of three interacting systems:

• Ego: The conscious mind with thoughts and perceptions.
• Personal Unconscious: Forgotten or suppressed memories that influence behavior.
• Collective Unconscious: Shared human experiences and universal symbols called archetypes.

Jung classified personalities into two main attitudes based on energy direction:

Each person experiences the world using four primary functions, each expressed in introverted or extroverted forms:

• Thinking (T): Decision making based on logic and objective reasoning.
• Feeling (F): Decision-making based on values and emotions.
• Sensing (S): Perceiving concrete, present realities.
• Intuition (N): Perceiving possibilities and abstract ideas.

These combine to form eight personality types (e.g., Extraverted Thinking, Introverted Feeling).

Building on Jung's model, the MBTI sorts personalities into 16 types by combining:

• Introversion (I) / Extroversion (E)
• Sensing (S) / Intuition (N)
• Thinking (T) / Feeling (F)
• Judging (J) / Perceiving (P)

Examples include INFJ, ESTP, etc., each representing a unique combination of traits.

• Introverts recharge their energy by spending quiet, reflective time alone.
• Extroverts gain energy from social interaction and lively environments.
• Ambiverts balance both introvert and extrovert traits, adapting to situations.

Daily example: An introverted student prefers studying alone, while an extroverted student thrives in group projects.

• Jung divided people into introverts (inward-focused) and extroverts (outward-focused).
• The mind has three parts: ego (conscious), personal unconscious, and collective unconscious (shared symbols).
• People use four main functions: thinking, feeling, sensing, and intuition—each can be introverted or extroverted.
• The MBTI test builds on Jung’s theory and creates 16 personality types.
• Introverts enjoy alone time, extroverts prefer socializing, and ambiverts balance both.
