INTJ (Introversion, Intuition, Thinking, Judgment)
Hallmarks of the INTJ include independence of thought and a desire for efficiency. They work best when given autonomy and creative freedom. They harbor an innate desire to express themselves by conceptualizing their own intellectual designs. They have a talent for analyzing and formulating complex theories. INTJs are generally well-suited for occupations within academia, research, consulting, management, science, engineering, and law. They are often acutely aware of their own knowledge and abilities—as wellas their limitations and what they don’t know (a quality that tends to distinguish them from INTPs). INTJs thus develop a strong confidence in their ability and talents, making them natural leaders.
According to the Keirsey Temperament Sorter’s Portrait the Mastermind (INTJ),
All Rationals are good at planning operations, but Masterminds are head and shoulders above all the rest in contingency planning. Complex operations involve many steps or stages, one following another in a necessary progression, and Masterminds are naturally able to grasp how each one leads to the next, and to prepare alternatives for difficulties that are likely to arise any step of the way. Trying to anticipate every contingency, Masterminds never set off on their current project without a Plan A firmly in mind, but they are always prepared to switch to Plan B or C or D if need be.
