Although they are highly capable leaders, Masterminds are not at all eager to take command, preferring to stay in the background until others demonstrate their inability to lead. Once they take charge, however, they are thoroughgoing pragmatists. Masterminds are certain that efficiency is indispensable in a well-run organization, and if they encounter inefficiency-any waste of human and material resources-they are quick to realign operations and reassign personnel. Masterminds do not feel bound by established rules and procedures, and traditional authority does not impress them, nor do slogans or catchwords.

Fieldmarshals will usually rise to positions of responsibility and enjoy being executives. They are tireless in their devotion to their jobs and can easily block out other areas of life for the sake of their work. Superb administrators in any field - medicine, law, business, education, government, the military - Fieldmarshals organize their units into smooth-functioning systems, planning in advance, keeping both short-term and long-range objectives well in mind. For the Fieldmarshal, there must always be a goal-directed reason for doing anything, and people's feelings usually are not sufficient reason. They prefer decisions to be based on impersonal data, want to work from well thought-out plans, like to use engineered operations - and they expect others to follow suit. They are ever intent on reducing bureaucratic red tape, task redundancy, and aimless confusion in the workplace, and they are willing to dismiss employees who cannot get with the program and increase their efficiency. Although Fieldmarshals are tolerant of established procedures, they can and will abandon any procedure when it can be shown to be ineffective in accomplishing its goal. Fieldmarshals root out and reject ineffectiveness and inefficiency, and are impatient with repetition of error.

Introverted Sensing (Feeling)

Sensing is introverted and often invisible. This stealth function in the third position gives INFPs a natural inclination toward absent- mindedness and other-worldliness, however, Feeling's strong people awareness provides a balancing, mitigating effect.

They are usually right, and they usually know it.

Rational Portrait of 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.

Alan Greenspan, Ben Bernanke, Dwight D. Eisenhower, General Ulysses S. Grant, Frideriche Nietsche, Niels Bohr, Peter the Great, Stephen Hawking, John Maynard Keynes, Lise Meitner", Ayn Rand and Sir Isaac Newton are examples of Rational Masterminds.
