The "4 quadrants of personality" typically refer to the DISC model, which categorizes behavioral styles into Dominance (D), Influence (I), Steadiness (S), and Conscientiousness (C). These quadrants help understand how people approach tasks, interact with others, and handle challenges, often visualized on two axes: task-oriented vs. people-oriented and direct vs. indirect communication. Other systems use different labels like Driver, Expressive, Amiable, Analytical or A, B, C, D but map to similar core drives, stemming from ancient theories of the four temperaments (choleric, sanguine, phlegmatic, melancholic).
Hippocrates named the four personality types after specific body fluids: Choleric, Melancholic, Phlegmatic and Sanguine. These four temperaments are rooted in the humoral theory of medicine and have persisted through history under different interpretations and adaptations.
In Operant Conditioning Theory, there are essentially four quadrants: Positive Reinforcement, Positive Punishment, Negative Reinforcement, and Negative Punishment. What do you think of when you read “Positive” and “Negative”? Good and bad, is the first thing that comes to mind.
The Greek philosopher Hippocrates labeled these categories of behavior as choleric, sanguine, phlegmatic, and melancholic.
The four temperament theory is a proto-psychological theory which suggests that there are four fundamental personality types: sanguine, choleric, melancholic, and phlegmatic.
Some use the acronym OCEAN (openness, conscientiousness, extraversion, agreeableness, and neuroticism) to remember the Big 5 personality traits. CANOE (for conscientiousness, agreeableness, neuroticism, openness, and extraversion) is another option.
It consists of four quadrants:
The MBTI (Myers-Briggs Type Indicator) uses four core categories (dichotomies) to sort personalities: Extraversion (E) or Introversion (I) (energy focus), Sensing (S) or iNtuition (N) (information gathering), Thinking (T) or Feeling (F) (decision making), and Judging (J) or Perceiving (P) (lifestyle/structure), resulting in 16 distinct personality types from combinations like INTJ or ESFP.
The combination of the two axes gives rise to the four quadrants: interior-individual; exterior-individual; interior-collective; and exterior-collective. The key elements of the four quadrants are captured in this table and described in more detail below.
Results yielded scales consistent with the Big Four model of personality (i.e., Neuroticism, Conscientiousness, Introversion, and Antagonism) and not the Big Five as there were insufficient items related to Openness. Resulting scale scores demonstrated strong internal consistency and temporal stability.
The DiSC model describes four main styles: D, i, S, and C. D is for Dominance, i is for Influence, S is for Steadiness, and C is for Conscientiousness. Everyone is a mixture of each style, but most people tend to fall into one or two main DiSC style quadrants.
The four temperaments are sanguine, choleric, phlegmatic, and melancholic. Temperaments are mainly shaped by genetics and can be influenced by childhood experiences. Knowing your temperament can help you understand your behaviors and reactions better.
ESFJ (the caregiver) are very warm, compassionate, and helpful people. They are often willing to go the extra mile for others. Other personality types like ISFJ, INFJ, ENFJ, ENFP, and ISFP are also loyal, kind, and gentle souls, and personalities to have as friends, leaders, and family.
Carl Jung's psychological types theory suggests that people experience the world using four principal psychological functions – sensation, intuition, feeling, and thinking – and that one of these four functions is dominant for a person most of the time.
INFJ. INFJ, also known as the advocate, counselor, or idealist, is the rarest type of personality in the general population. It represents about 1.5% of the general population in the United States.
Characteristics of Phlegmatic Temperament
Before we go into the reasons why they are important, let's quickly remind ourselves of what they are. The five broad personality traits described by the theory are extraversion (also often spelled extroversion), agreeableness, openness, conscientiousness, and neuroticism.
One Myers-Briggs® Celebrity INTP Personality Type is theoretical physicist Albert Einstein.
Zuckerberg is an INTJ, which is one of sixteen personality types from the famous Briggs/Myers personality type model that describes someone's perception of the world. INTJ stands for Introverted, Intuitive, Thinking, and Judging, four personality traits described by psychoanalyst Carl Jung.
Any personality test can be fun and intriguing. But from a scientific perspective, tools such as the Big Five Inventory (and others based on the five-factor model) and those used by psychological scientists, such as the MMPI, are likely to provide the most reliable and valid results.
