I'd say absolutely for groups where there's an activity which needs structure. However, I wouldn't see this in a situation that doesn't require goal setting and coordination of competencies, such as a recreative/social group.The basic driving force and need of ENTJ's is to lead, and from an early age they can be observed taking over groups
This passage seems a little bit far fetched. It sounds like an individual with a personality disorder!The ENTJ is a natural "fieldmarshal," that is, he's itching to get his hands on several "armies" so that he can marshal his forces and conduct the "war" as it should be conducted. If our ENTJ is in charge of any kind of enterprise, however small, his temperament dictates that he run it as he would his armies-with an eye to long-term strategies and their derivative tactics, logistics, and consequences.
I'm not convinced about Keirsey's descriptions. I really like his NT description and can recognize myself alot in it. I tend to find the temperaments pretty interesting. However, the individual descriptions seem to fall short compared to the official MBTI.
What about you? Which descriptions fit you best?
