i can't decide whether more information is better, but i went primarily by aushra augusta's the dual nature of man and couldn't balance between V.I. and definitions when typing myself (but I know that Ne is my weakest function, it's certainly my older brother's weakest function). I went with her definitions primarily (even though they're ambiguous which irritates me) since she was the creator of socionics even though she left out subtypes, which change a lot of her original theory (to be more precise, it means just 16 types doesn't mirror themselves and reality/people very well) and seemingly even reinin dichotomies. Simply, subtypes are glaringly obvious in most cases and I usually go by memories of my meetings with people and what other people say... i guess i've never really understood theory well, but i don't do so well with practice either... i am more oriented towards practice though, thinking the real world, physical interaction, and economic success are more important and better than being a researcher/always with books... i'm not the most open-minded person, when i was a kid i was super materialistic and loved good tangible things (and often playing with them with others although at other times hated it when others touched my things and i could get very, very angry from it, i was a mean kid) and good sensations.
if gammas truly were what made for bright lights and stores popping up everywhere when i was a kid and betas were the catholic church, then, well you get the idea that i enjoyed gamma more/they made my little pecker more hard...
