Do ENTps and INTjs with their penchant for experience a 'need' for external information about the world around them as directed by to keep active and healthy? Are the shades of this interaction different - to any sizeable extent - based on whether a person's primary function as or ?
The impression I get of is that it's largely self-entertaining. Of course, the caveat here is that too much isolation breeds a certain amount of intellectual and emotional 'incest', if you will. Considerations of pure logic aside, if we expand the scope of the discussion to include type theory within its human, social context (as we have, as we should) one could make an obvious argument that informed by no other function such as leads to a disasterous result.
It is one thing to read political theory or philosophy and compare it with one's own views in the abstract, theoretical sense. It's another to turn on the TV news and watch the principles play themselves out in real-time drama. I would think that would be a virtual romper-room for Thinking types as it afford the passive exercise of knowledge, as well as the active exercise of possibility.
How about at an emotional level? Does an inhibited cut off from the outside world lend to depressive/apathetic states in ENTps and INTjs?
