Hi, I've joined this forum (and this thread) just to discuss/argue about MBTI typing for our favorite cartoon.
According to http://www.truity.com/view/types
, Applejack is not intuitive. Rather, she is very practical in her mindset, and not one to conjure and create new ideas for herself or her friends. In addition, she's excessively stubborn, and causes problems because of this trait. So, I would say she is ISFJ.
Fluttershy, on the other hand (hoof), constantly has her head in the clouds, is an extreme idealist, and is constantly seen caring for and nursing animals. She's the only pony who can forgive and befriend Discord unconditionally. INFP for sure.
Due to lack of time at my time of posting, I'll briefly state what my opinions on the other main pony cast are: PP is ESFP, RD is ESTP, Rr is ENTJ, and TS is ISTJ.
Edit: TS is INTJ (scientist demeanor)
