“What did the online personality type say to the doctor after running some tests? Is this going to be viral?” – Comedian unknown

Personality jokes aside if, at some point in your life, you have ever wondered what your personality type is, then you must have taken a Personality test. Now, there are tonnes of personality questionnaires and tests available online but the Myers-Briggs Personality Type Indicator is probably the most widely used personality test in the world.  

It’s also one of the most regularly debunked even though about 2 million people take it annually.  It is believed that these tests are based on some long-standing myths about what personality really is and how we can measure it. 

A personality test can give you a great deal of insight into the core components that make up who you are. Personality is a thing that individuals informally assess and describe every day. During interactions, people frequently refer to different characteristics of an individual’s personality.

Your job depends on it, your marriage compatibility gets a cue from it. But are personality tests still valid? Most personality assessment instruments are in fact introspective. Personality tests use questionnaires as a data collection method to know more about your personality type, your intelligence, your interpersonal skills, and more!

What is a Personality Test?

A personality test is any of a series of standardized tests designed to accurately and consistently measure personality. It is simply a way to assess an individual’s personality construct. Most personality tests are coined into introspective self-report questionnaire measures from life records such as ratings. 

Personality tests are primarily used for identifying perceived strengths and weaknesses in the character combinations of an individual to give them a direction such that only their strengths are amplified and the weaknesses reduced to a bare minimum or eliminated.

What are the Four Temperament Personality Types?

A study from Carlos III University of Madrid shows behavior types of 90 percent of the human population can be grouped into; optimistic, pessimistic, trusting, and envious. Individuals are either; optimistic, pessimistic, trusting, and/or envious.

Of the four types, envious, is the most common, with 30 percent compared to 20 percent for each of the other groups. Unlike Myers-Briggs, this temperament theory has its roots in the ancient four humors theory.

A more common and widely accepted explanation of personality types is the four temperament theory. A proto-psychological (the study of human psychology) theory which suggests four fundamental personality types: sanguine, choleric, melancholic, and phlegmatic. 

These were associated with the domination of various biological functions. These temperaments come to the most obvious manifestation in childhood, between 6 and 14 years of age, after which they become subordinate (in most cases).

  • Sanguine (optimistic, active, and social)

Sanguines tend to be more extroverted and enjoy being part of a crowd. Sanguine personality is typically described as highly talkative, enthusiastic, active, and social. Individuals with this personality have a hard time doing nothing and engage in more risk-seeking behavior.

  • Choleric (short-tempered, fast, or irritable)

Choleric individuals tend to be more extroverted. They are described as independent, decisive, and goal-oriented, and ambitious. These combined with their dominant, result-oriented outlook make them natural leaders. In ancient history, they were thought to be violent, vengeful, and quick-tempered.

  • Melancholic (analytical, wise, and quiet)

Melancholic individuals tend to be analytical and detail-oriented, and they are deep thinkers and feelers. They are introverted and try to avoid being singled out in a crowd. A melancholic personality leads to self-reliant individuals who are thoughtful, reserved, and often anxious because they strive for perfection.

  • Phlegmatic (relaxed and peaceful)

Phlegmatic individuals tend to be relaxed, peaceful, quiet, and easy-going. They are empathetic towards others, yet they try to hide their emotions. Phlegmatic individuals also are good at generalizing ideas or problems to the world and making compromises.

Origin of the Myer-Briggs Personality Tests

Katharine Cook Briggs, mother of Myer Briggs began research into personality in 1917. She developed a typology wherein she proposed four temperaments: meditative, spontaneous, executive, and social. Isabel Briggs Myers followed her mother’s typological research and with time, took it over entirely.

Briggs and Myers created the MBTI during World War II believing that consciousness of personality preferences would help women who were joining the industrial workforce for the first time to identify the kind of war-time jobs that would best suit them.

Myer-Briggs Personality Types (Socionics Theory)

Socionics, in psychology and sociology, is a theory of information processing and personality type, distinguished by its information model of the psyche. The idea of Socionics is that information is intuitively divisible into eight categories, called information aspects, which a person’s psyche processes using eight psychological functions. 

The purpose of Socionics is to provide a means of predicting the character of relations and the degree of business compatibility, information sharing, and psychological compatibility of people before their joining in one collective group.

Socionics is extraversion (E), sensing (S), thinking (T), judgment (J), introversion (I), intuition (N), feeling (F), and perception (P). 

Socionics divides people into 16 different types, called sociotypes which are; ESTJ, ENTJ, ESFJ, ENFJ, ISTJ, ISFJ, INTJ, INFJ, ESTP, ESFP, ENTP, ENFP, ISTP, ISFP, INTP & INFP. A formal conversion is carried out following the Myers–Briggs Type Indicator.

How To Know Your Personality Type

When it comes to individuals and their personalities, there are a lot of important determinants that come into play. In trying to understand your true nature, a key factor is knowing one’s distinct personality type. No personality type is superior to the other in the grand scheme of things as they both have seemingly equal pros and cons.

Originally, there are two main personality types which are Types A and B. This helps classify the four temperaments and 16 personalities into similar broad categories. To know which type you are, you can take this personality Type A/B questionnaire—a modified version of the Jenkins Activity Survey.

  • Type A Personality

Type A individuals are multitasking, ambitious, proactive, organized, and status-conscious individuals. In addition, they are sympathetic, sensitive, truthful, and always eager to help others. Type A people are friendly and caring goal-driven and motivated individuals. They are also easily frustrated and have a low tolerance for incompetence with people or projects.

  • Type B Personality

Type B individuals are laid-back with the ability to relax and enjoy small accomplishments. In addition, they tend to be calm, patient individuals and are generally uncompetitive as they often take the “win some, lose some” approach. They are rarely stressed and hardly ever frustrated with people or projects.

Here’s how you really know though. If you read through painstakingly the above line by line, you’re likely an A. If you skimmed through the text, you’re probably a B.

Studies show that there are also Type C and Type D personalities away from Type A and B personalities. The difference is, while Types C and D require more analysis and appear to be more emotionally driven characteristics, Types A and B are driven by certain, easily recognizable, and consistent characteristics.

  • Type C Personality

Type C individuals have a hard time sharing their emotions, feelings, and/or needs with others. They are considered to be emotionally repressed. They find it extremely difficult when it comes to making decisions of low and/or large magnitude. They are naturally people pleasers. 

  • Type D

Type D individuals are usually a combination of stressed, angry, worried, hostile, and tense. They run a strict unchanged pattern of lifestyle and are averse to making changes. For the Type D individual, security is a top priority. Whether it’s physical security and/or job security. 


The entire purpose of personality tests is that the tests can be used for self-reflection and help individuals attempt to understand themselves towards improving their interaction with others. 

For instance, if a job placement requires a certain character trait or personality type, simply taking a personality test helps best decide who best fits that role and removes the risk of people going into the wrong jobs.

Above all, personality tests show the strengths and weaknesses of an individual. With this key information, you can now focus on amplifying your strengths and suppressing your weaknesses.
