This article is about the Myers-Briggs personality type. For the Socionics ENTJ, see Logical Intuitive Extrovert. ENTJ (extraversion, intuition, thinking, judgment) is an abbreviation used in the publications of the Myers-Briggs Type Indicator (MBTI) to refer to one of sixteen personality types. The MBTI assessment was developed from the work of prominent psychiatrist Carl G. Jung in his book Psychological Types, which proposed a psychological typology based on his theories of cognitive functions. From Jung’s work, others developed psychological typologies. Jungian personality assessments include the MBTI assessment, developed by Isabel Briggs Myers and Katharine Cook Briggs, and the Keirsey Temperament Sorter, developed by David Keirsey. Keirsey referred to ENTJs as Fieldmarshals, one of the four types belonging to the temperament he called the Rationals. ENTJs are among the rarest of types, accounting for ~2–5% of males formally tested, and ~1-3% of females, and is the personality type most often associated with the alpha animals in ethology. ENTJ types tend to be self-driven, motivating, energetic, assertive, confident, and competitive. They generally take a big-picture view and build a long-term strategy. They typically know what they want and may mobilize others to help them attain their goals. ENTJs are often sought out as leaders due to an innate ability to direct groups of people. Unusually influential and organized, they may sometimes judge others by their own tough standards, failing to take personal needs into account. In addition, since the ENTJ type is unusually skilled in persuasion, subjects with this type of personality can be negatively perceived as being manipulative if his/her natural talents are abused.
