INTJ

INTJ (introversion, intuition, thinking, judgment) is an abbreviation used in the publications of the Myers-Briggs Type Indicator (MBTI) to refer to one of the 16 psychological types.

According to Myers-Briggs the INTJ represents "The Mastermind". INTJs are one of the rarest of the 16 psychological types and account for approximately 2% of the population. Women of this personality type are especially rare, forming just 0.8% of the population.

The MBTI assessment was developed from the work of prominent psychiatrist Carl G. Jung in his book Psychological Types. Jung proposed a psychological typology based on the theories of cognitive functions that he developed through his clinical observations.

From Jung's work, others developed psychological typologies. Jungian personality assessments include the MBTI instrument, developed by Isabel Briggs Myers and Katharine Cook Briggs, and the Keirsey Temperament Sorter, developed by David Keirsey. Keirsey referred to INTJs as Masterminds, one of the four types belonging to the temperament he called the Rationals.

Prominent American INTJs are believed to include John F Kennedy, Thomas Jefferson, Woodrow Wilson, Dwight D. Eisenhower, Calvin Coolidge, and James K. Polk.
