Definition/Introduction

The Myers-Briggs Type Indicator (MBTI), developed by Isabel Myers during World War II, assesses personality types based on the theories of psychologist Carl Jung. The MTBI was designed to facilitate and improve working relationships among healthcare professionals, particularly nurses.[1] Myers designed this questionnaire based on Jung's theory of "individual preference," which posits that the seemingly random variations in human behavior stem from fundamental differences in mental and emotional functioning.[2] Myers described these variations as different ways individuals prefer to engage their minds.

The MBTI operationalizes these preferences through questions that assess an individual's tendency toward one end of a spectrum in the following 4 categories:

Energy

Energy refers to the spectrum of extraversion to introversion. Individuals leaning toward extraversion focus their attention on external experiences and actions, drawing energy from their interactions with others. In contrast, those leaning toward introversion concentrate on their inner thoughts and ideas, gaining energy from solitude.

Perceiving

Perceiving describes how individuals prefer to take in information, ranging from sensing scales to intuitive types. Sensing types prefer gathering information through their 5 senses and collecting facts before understanding general ideas and patterns. In contrast, intuitive types rely on their instincts and approach problems from a "big picture" perspective, recognizing general patterns before identifying constituent facts.

Judging

Judging categorizes how individuals prefer to make decisions, ranging from thinking to feeling. Thinkers base their decisions on logic and facts, while feelers prioritize harmony in resolving issues.

Orientation

Orientation refers to an individual's preferred lifestyle on the spectrum between judging and perceiving. Those who lean toward judgment tend to favor an orderly, decisive, and structured lifestyle, while those who prefer a more flexible and unpredictable existence align with the perceiving type.[1]

A total of 16 personality types can be formed by combining 2 poles across 4 different categories. Each type is represented by a 4-letter code that indicates the individual's propensity in each category. For example, an individual who leans toward extraversion in energy, intuition in perceiving, thinking in judging, and perceiving in orientation would be classified as an ENTP.

The goal of the Myers-Briggs typology is to enhance self-awareness and understanding of others, facilitating the process of Jung's "individuation." This process involves integrating, differentiating, and developing one's traits and skills.[2] By understanding individual preferences, one can begin analyzing and applying them in both work and personal endeavors.
