Well, the main difference I found between ISTJ and INTJ was that ISTJ supposedly values "law and order", rules, and doing things by the book. INTJ tends to use their intuition more about what they think is right/wrong.
Yeah, they're really similar. I wish I recorded the percentages for each, I'm pretty sure the "S" on the first attempt was really low. Whatever, its no big deal, its just interesting to me.
Its one of those things that will vary each time I take the test depending on how I interpret the statement/question/whatever you want to call it. I mean, I just redid it again and got 1% on the S (ISTJ again). I'm leaning towards tendencies of both...
From what I've gathered I'm moderate on Thinking and Judgement, slight to moderate introvert, and slight sensing/intuitive. I'm looking into this way too much for a simple yes/no "quiz".
