Someone mentioned this thread to me, I've got to follow this obsessively now.
And thanks to
@SourRoses for actually mentioning cognitive functions. You're doing the Lord's work.
I test consistently as an INTJ by the four-letter distinction, but the more I research functions the less I recognize introverted intuition as a dominant function for myself. Leaning more towards INTP now, perhaps the potential lack of Fi could account for constant re-evaluating of type?
If anyone is interested in further testing their type and getting a more accurate result, I'd recommend this one:

It is much more thorough and actually addresses the functions.
Does anyone here use MBTI as a tool for writing?
