Type 4 is between two competency types: 3 and 5. Regardless of the wing, a type 4 will have influence from both sides. Type 4 also has a direct line to 1, the third competency type.
Type 3 influence might bring a 4 a desire to be identified by their work, while type 5 influence might bring a 4 a very strong thirst for knowledge and understanding as part of their identity. Also, 4's have a direct integration line to 1, which might bring a desire for truth and correctness.
So I am wondering:
How concerned are you with competency?
Does it give you a sense of identity or purpose to be good at something?
Do you want others to know what you're good at, or do you do it just for yourself?
Would an accomplishment feel less authentic or genuine if you showed it off?
Is perfection and correctness important to you? Is this part of your definition of authenticity?
