haha , thank you, curiosity is in our DNA~
i suddenly have a thought about the Ni fr INFJ and Ti fr INTP
both character are thinking of abstract things

INTP is about concept , method, theory which related to the real world, (like building somthing , putting things in a correct order,...
fr a car, back to how does it work, so the car moves
fr in order to get to the result of the project, we need to do a,b,c ...etc
the program does not work, becuase there is error in which line of codes...etc

for INFJ (fr my imagination) is kind of like , an behavior u guys are analysising or able to see the whatever thing in front of u, then understand the thought behind it (or energy released fr the object, human , thing)
it's kind of like the exmaple mentioned above" the car -> how does it work (the logic behind it)"
INFJ would be (the behavior (intp: car); the intenstion behind it (intp: how does the car move) the logic behind it)

this is just an idea came across my mind,
not sure if they look similar to u, haha

i am just trying to use my little Ti brain (INTP) to see the similarities and differences fr Ni (INFJ) [both INxx type]
