What's so wacky about Ne anyways? Been trying to figure that out. It doesn't have any basis in cognitive definitions, nor do Ne dom "type descriptions" talk about it. I've been led to assume Ne is more about seeing the interplay between multiple views/experiences... drawing up possibilities from across the board. Maybe someone with a holistic approach in their values or ideas. Maybe some could be wacky, but it's probably not even type related.
I could be wrong -- but I always thought of Ne (again, my personal experience) -- as being able to see a whole bunch of possibilities at once. Many of the Ne-dom type descriptions discuss the torrential outpouring of ideas. I've found that this leads to several real-life implications:
1) I can't prioritize, so having a conversation with me is like talking to a random topic generator. I can talk about nothing at all or about everything, and its relevance to others around me (at times) is subordinate to the fact that I can't seem to shut up about my observations.
2) Many of the connections that I make aren't even linear. I can't say X leads to Y leads to Z. X can lead to A prime, squirrels and this stupid bedspread that's giving my skin some serious agita.
3) Because of my tendency to process things out loud, I find that my whole physical being is a conduit for my possibilities/ideas. Sometimes, this leads me to overexcitement, paranoia, and long binges of useless research on (irrelevant) topics.
I'm not sure how I can extrapolate these ridiculous points and say that this is true for all ENFPs or even Ne-doms (though according to type descriptions, ENTPs are more likely to be logical about their arguments/connections). But this is how I've observed Ne-dom wackiness. Se-dom, Te-dom and Fe-dom wackinesses are also great big parts of my life, so I'm not going to claim that Ne has any monopoly on the craziness. It doesn't. But my behavior certainly makes for some socially unacceptable craziness at times.
