Ne doms are usually "silly" in some sense of the word (and if they aren't silly they usually at least have their hand in geek culture to some extent). Ne creatives are more subtle in their sense of humor but they are generally much more rigid than you come across. Honestly, you could probably just look at the Ne egos on this forum and know what I mean. I would do more to convince you but I really doubt I'd have to. If you aren't ILI you are probably ESI, but I think it's clear enough that you prioritize the intuitive and logical functions over the sensory and ethical.
