"The Myers–Briggs Type Indicator (MBTI) assessment is a psychometric questionnaire designed to measure psychological preferences in how people perceive the world and make decisions." "The 16 types are typically referred to by an abbreviation of four letters—the initial letters of each of their four type preferences (except in the case of intuition, which uses the abbreviation N to distinguish it from introversion)."
Basically, according to the MBTI personality indicator, there are 16 different types of unique personalities in the world, all of which have different combinations of the said four types of dichotomies: (Though everyone will at some point, show conflicting dichotomies during different situations like being an extrovert in school while an introvert at home, MBTI personality tests measure your more dominant dichotomies, the traits you display the most)
Extrovert (E) or Introvert (I)
The INFJ personality type is very rare, making up less than one percent of the population, but they nonetheless leave their mark on the world. As Diplomats (NF), they have an inborn sense of idealism and morality, but what sets them apart is the accompanying Judging (J) trait – INFJs are not idle dreamers, but people capable of taking concrete steps to realize their goals and make a lasting positive impact.
INFJs indeed share a very unique combination of traits: though soft-spoken, they have very strong opinions and will fight tirelessly for an idea they believe in. They are decisive and strong-willed, but will rarely use that energy for personal gain – INFJs will act with creativity, imagination, conviction and sensitivity not to create advantage, but to create balance. Egalitarianism and karma are very attractive ideas to INFJs, and they tend to believe that nothing would help the world so much as using love and compassion to soften the hearts of tyrants.
