There was a real good point in another thread about ENTP knowledge style: that some ENTP study information only to that depth that they can appear knowledgeable. It's interesting view.
Another comment said that ENTP exchange depth for breadth in almost anything they do. On the other hand, some web descriptions have noted that ENTPs wish to have such areas of expertise where they are second to none.
Apart from wanting to make an impression, or to excel and to win, descriptions (and my observations and self-analysis) suggest that ENTPs mostly gather information to get more coping abilities, to handle a wider area of problems skillfully. This means both those challenges that the ENTP chooses themselves, and those challenges where the ENTP just finds themselves in.
In other words, ENTP would maximize the number of topic areas where they are notably better than their "competitors", even if that would be just "introductory level" knowledge about the topic.
INTPs are described as having the need to be intellectually competent, and to understand. I can agree to this a lot, altho the real situation is FAR from black-and-white. Is it perhaps that INTP choose a bit narrower topics of interest? I think that INTPs may be seen as "narrow" from a normal, usual perspective, where normal things are such as being nice, social, doing work, earning money, liking regular things, etc. THis is not ment as hostile, I support INTP way of life.
how I see it
How do you see ENTP and INTP in this respect? I see as ENTP gathering about the widest possible knowledge base and know-how amongst any types, perhaps on par with ENFP (on a second thought, no. ENFP handle many issues gracefully, but it's less book-knowledge-based and more the style of pulling social strings, even if just by a slight measure). Knowledge tends to be superficial and amateurish in many areas, but it's usable, and ENTP improvises 95% in any situations anyway, so that the low level of knowledge is just a starting point for ENTP to do their thing. THis, and ENTP seems to go INTP:ishly deep in some areas, too.
INTP on the other hand, when viewed from outside, seems to be content in concentrating their efforts in fewer areas of expertise. Not very narrow at all: areas the size of "contemporary literature" or "marine biology" or similar. They are broader than some practical hands-on skilled work, but narrower than ENTP's interests.
I would see INTPs coping skills as such that INTP arranges for their neglected topic areas to not to interfere with their lives. They do cope and manage and it's all allright. It just seems like a different approach from ENTP.
Have I got this all wrong, or what kind of perceptions do you have about the issue?
