Lol, well ENTPs are voted funniest MBTI type

I think personality can change drastically if you put in the effort, want to, are in that environment of the function you want to develop and make it consistent.

I'm not sure on the exact meaning of middle ground, I agree with the jiste of that idea and kinda with balance. I'm about extremes though. If you master both ends of a spectrum, you can be everything in between.

Instead of pretending and being "tactful" with others, you can be sincere and really understand.

I think your T is using the test as a base for you to grow from. We can get lost so easily in our disorders. Hell, i've retyped this response 3 times, different explanations, due to my perfectionism problem, lol.

Try the Jung Cognitive Function Test (basically what MBTI was "built upon)
Jungian Cognitive Functions Test

My INFJ GF (and is very much an INFJ), her result on the above , was literally "unknown" lol.

Would be interesting to see if anyones Jung Cognitive function result is different from their MBTI. (MBTI = INTP. Jung = ENFP. My reflection and research - No doubt i'm an ENTP)
