Talking about my sig? I deliberately made it other than INTP to make a statement.
I think I'm INTP because I have difficulty with arbitrary decision-making (sometimes use algorithms). Also, I work up until the deadline on papers not because of procrastination but because of excessive analysis, never picking an idea until I absolutely must (there's always a better idea around the corner).
I see schedules more as suggestions, a cure for not knowing what to do. If anything, I'm more likely ENTP than INTJ considering I love new ideas more than pretty much anything else. I haven't found a group of N-types, so I don't know if I'd like to hang out with groups. I'm pretty expressive and am usually bored rather than drained from social interaction, but if no new ideas are to come from it (aka drinking party) I'll take books to people any day. Definitely introspective though.
Does that answer your question or is there something else about my type that seems off?
