If you believe at all what Keirsey writes:
ENTP - informative
ENTJ - directive
Instead of summarizing this on my own, I'm going to be an ass and start quoting Keirsey directly.
ENTPs, according to Keirsey, have "
less and less desire, if they ever had any,
to direct the activities of others, doing so only when forced to by circumstances."
NTPs have an "engineering and design" intelligence, and are less developed at "marshaling" and "contingency planning." Keirsey writes of ENTP Inventors:
"Outgoing and intensely curious, Inventors are apt to express interest in finding out about everything they come into contact with, and this can be a source of inspiration to others, who find themselves admiring the Inventor's insatiable hunger for knowledge."
ENTPs in particular, have highly developed "inventive" intelligence, hence they "characteristically have an eye out for a better way, always on the lookout for new projects, new activities, new procedures."
This causes them to be "the most reluctant of all the types to do things in a particular manner just because that is the way things have always been done," and in part gives them their anarchistic reputation because they "are confident in the value of their interests and display a charming capacity to ignore the standard, the traditional, and the authoritative."
The theme here is that ENTPs want to exercise their inventiveness and design new, better, and more innovative ways of doing, seeing, and thinking about things. They are *not* directive, and if left to their own devices have little or no desire to control others or impose order upon reality -- they only want to solve the problem.
ENTJs, on the other hand are directive. They "are bound to lead others, and from an early age they can be observed taking command of groups."
The natural leadership of the ENTJ is a manifestation of their "strong natural urge to give structure and direction wherever they are -- to harness people in the field and to direct them to achieve distant goals... [ENTJs] more than any other type desire (and generally have the ability) to visualize where the organization is going, and they seem able to communicate that vision to others."
They aren't stewards of an organization, though, Keirsey makes a point of saying that although ENTJs "are tolerant of established procedures, they can and will abandon any procedure when it can be shown to be ineffective in accomplishing its goal."
The prime motivation here is for
efficiency. As Keirsey describes ENTJs:
"... 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."
The theme here is a ruthless reformer of systems (be them organization, scientific, etc.) into more efficient and manageable systems. They are *not* informative and, if they have anything to say about it, people won't be mulling around filing TPS reports. And while they are innovative, an ENTJ in charge of NASA is not going to let the ENTPs invent a pen that works in zero-gravity when they could just use a pencil. (I mean this in the most metaphorical sense, of course.)
The supposed salesmanship and "tactical" awareness of ENTPs discussed in this thread, seriously, is almost textbook ESTP, who "have no hesitation at all in approaching strangers and persuading them to do something."
Keirsey writes that ESTPs are the Promoters, defining it as such:
Promoting is the art of winning others to your position, giving them confidence to go along with what you propose, and [ESTPs] seem especially able to maneuver others in the direction they want them to go. In a sense, they are able to handle people with much the same skill as [ISTPs] handle tools, operate machines, or play musical instruments. You might say that people are instruments in the [ESTPs'] hands, and that they "play" them with great artistry.
Again -- this is because ESTPs are
directive, and they happen to be directive in this particular way.
