Isabel Briggs Myers (October 18, 1897 – May 5, 1980)[1][2] was an American psychological theorist. She was co-creator, with her mother, of the Myers-Briggs Type Indicator (MBTI).’

The 'Isabel Briggs MyersType Indicator (MBTI) assessment is a psychometric questionnaire designed to measure psychological preferences in how people perceive the world and make decisions.[1]:1 These preferences were extrapolated from the typological theories proposed by Carl Gustav Jung and first published in his 1921 book Psychological Types (English edition, 1923).[2]

The original developers of the personality inventory were Katharine Cook Briggs and her daughter, Isabel Briggs Myers. They began creating the indicator during World War II, believing that a knowledge of personality preferences would help women who were entering the industrial workforce for the first time to identify the sort of war-time jobs where they would be "most comfortable and effective".[1]:xiii The initial questionnaire grew into the Myers-Briggs Type Indicator, which was first published in 1962. The MBTI focuses on normal populations and emphasizes the value of naturally occurring differences.[3]

CPP Inc., the publisher of the MBTI instrument, calls it "the world's most widely used personality assessment",[4] with as many as two million assessments administered annually. The CPP and other proponents state that the indicator meets or exceeds the reliability of other psychological instruments[5][6] and cite reports of individual behavior.[7] Some studies have found strong support for construct validity, internal consistency, and test-retest reliability, although variation was observed.[8][9] However, some academic psychologists have criticized the MBTI instrument, claiming that it "lacks convincing validity data".[10][11][12][13] Some studies have shown the statistical validity and reliability to be low.[13][14][15] The use of the Myers-Briggs Type Indicator as a predictor of job success has not been supported in studies,[15][16] and its use for this purpose is expressly discouraged in the Manual.[17]

Isabel Briggs Myers added a fourth criterion, Judging-Perceiving.

The first letters of the different combinations of the four criteria denote a type formula. For example:

ISTJ-Introvert Sensing Thinking Judging

Upon completing Jung Typology Test you will obtain your type formula, strengths of the preferences and the type description. It may help you to identify your life style in general and with respect to the specific areas of activity. You will also obtain the list of the most suitable career choices based on your personality, along with some educational institutions where you can receive a relevant degree or a training

ISFP

Introversion(I)- ISFPs are introverted. They tend to be reserved and quiet, especially around people they do not know well. They prefer spending time with a close group of family and friends.

Sensing(S)- ISFPs like to focus on the details. They spend more time thinking about the here and now rather than worrying about the future. They also prefer concrete information to abstract theories.

Feeling(F)- ISFPs like to focus on the details. They spend more time thinking about the here and now rather than worrying about the future. They also prefer concrete information to abstract theories.

Perceiving(P)- ISFPs like to keep their options open, so they often delay making decisions in order to see if things might change or if new options come up.

------

Extraverted Feeling (Fe): Fe` seeks social connections and creates harmonious interactions through polite, considerate, and appropriate behavior. Fe responds to the explicit (and implicit) wants of others, and may even create an internal conflict between the subject’s own needs and the desire to meet the needs of others.

Introverted Sensing (Si): Si collects data in the present moment and compares it with past experiences, a process that sometimes evokes the feelings associated with memory, as if the subject were reliving it. Seeking to protect what is familiar, Si draws upon history to form goals and expectations about what will happen in the future.

Extraverted Intuition (Ne): Ne finds and interprets hidden meanings, using “what if” questions to explore alternatives, allowing multiple possibilities to coexist. This imaginative play weaves together insights and experiences from various sources to form a new whole, which can then become a catalyst to action.

Introverted Thinking (Ti): Ti seeks precision, such as the exact word to express an idea. It notices the minute distinctions that define the essence of things, then analyzes and classifies them. Ti examines all sides of an issue, looking to solve problems while minimizing effort and risk. It uses models to root out logical inconsistency.
