Interesting, I'm the same: INFP-T Mediator. I always come out as an INFP no matter what version of the test I take.
This all fits:
-Mediators often drift into deep thought, enjoying contemplating the hypothetical and the philosophical more than any other personality type.

--Mediators often take challenges and criticisms personally, rather than as inspiration to reassess their positions. Avoiding conflict as much as possible...

--This aversion to conflict, while contributing greatly to stability in the relationship when done right, is probably the most urgent quality for Mediators to work on. Between their sensitivity and imagination, Mediators are prone to internalizing even objective statements and facts, reading into them themes and exaggerated consequences, sometimes responding as though these comments are metaphors designed to threaten the very foundations of their principles. Naturally this is almost certainly an overreaction, and Mediators should practice what they preach, and focus on improving their ability to respond to criticism with calm objectivity, rather than irrational accusations and weaponized guilt.

--Mediators crave the depth of mutual human understanding, but tire easily in social situations

--The biggest challenge for Mediator parents, especially more Turbulent types who often have even more trouble with self-doubt than most, is to establish more practical and day-to-day structures and rules.
