I had to figure out what Thinking is exactly, in Jungian terms, because honestly, it never really felt important until now. I found this on Extraverted Thinking.
Psychological Types, C. G. Jung:
So, the word of the day is OBJECTIVELY oriented, which is so much of a better word than rational or logical since both thinking and feeling are actually rational, and since logicality is mostly just a synonym for practicality, which is an attitude both present in any goal oriented endevour, objective or subjective.
That leaves us with the question as to whether Thinkers are better logicians than Feelers. And I think they would have better reason to develop those skill, because logic is essentially the manipulation of objects, which the thinkers domain. Buuuut, a Thinker cannot be essentially objective and still function, they still have a subjective (Feeling) function that they need to operate as a person. The same for Feelers. The difference between Thinkers and Feelers is entirely in emphasis and not in essence. We're the same-ish, at least enough to invoke a canny valley, which is why this thread exists.
When I think of EJ I usually think of logistics, when I usually think of IP I think of someone focused on understanding. The goal of one is the input of the other in a way. Je vs Ji
