Science Behind MBTI- MECA Personalities


Science Behind MBTI- MECA Personalities

The Myers-Briggs Type Indicator is an introspective pseudoscience with the goal of identifying a person’s strengths, weaknesses, learning style, motivations, and preferences. It is a widely used personality inventory that has been employed in psychotherapy and educational settings. MBTI helps with understanding one’s self as well as the people around them.

There are 16 MBTI types total, all with their own cognitive function stack and 4 letter label. Cognitive functions, in relation to Myers Briggs, are mental processes that are present in any event (regardless of specific event). Based on your strongest, auxiliary, tertiary, and inferior function, you are assigned four letters. These four letters each have their own representation in one’s personality.

The eight functions in MBTI are: extroverted thinking (Te) or introverted thinking (Ti), extroverted intuition (Ne) or introverted intuition (Ni), and extroverted feeling (Fe) or introverted feeling (Fi). Each function has an opposite, meaning if it is your dominant/strongest function, its opposite would be your inferior/weakest function. An example of this would be in the type ENFJ. ENFJs are social, so their dominant function is Extraverted Feeling. However the opposite of Fe is Ti, meaning their inferior function is introverted thinking. This means ENFJs may not be confident in their own ability to be internally logical. The order of functions are: dominant, auxiliary, tertiary, and inferior. Your dominant function is the most used function. Your auxiliary function assists the dominant function. Tertiary functions are a bit more flexible, and its meaning changes based on the type. Your inferior function is underdeveloped and rarely used.

Which Star Wars character are you?

Your function stack stack determines your letter code. If your dominant function is extroverted, your first letter will start with E, meaning extraverted. . The second letter can either be N or S, meaning intuitive or sensing. If you are intuitive, you are visionary, abstract, and open to change. Sensors are more down to earth, concrete, and live in the moment. The third letter is either T or F, meaning thinking or feeling. This focuses on decision making. Thinkers have a tendency to be blunt, distant, and value logic. Feelers are warmer, take others into account in making decisions, and value harmony. Logical feelers and friendly thinkers do exist, however. The last letter is either a P or J, meaning perceiving or judging. Perceivers are less organized than judgers and are more flexible with planning. Judgers prefer closure and fast decision making.

The founders of MBTI are Katharine Cook Briggs and her daughter Isabel Briggs Myers. It began in the early mid-20th century in the United States.

There are some to disagree with the concept of Myers Briggs. The common argument is that MBTI is only popular because of its simplicity. It advertises the ability to deliver elaborate and accurate descriptions of one’s personality. It’s easy to understand and that is its allure. However, the concept as a whole is believed to force binary behavior and be self-fulfilling. If one sees they hold a strength in one aspect, they may go out of their way to overperform in that area.

Some reliable, psychology-based tests you can take include sakinorva and keys2cognition. However, every test has the capacity to mistype. The most accurate way to find out your MBTI is by researching cognitive functions and determining what applies to you.
