Decided to give the test in the OP link a shot:
INTP
Introvert(100%) iNtuitive(88%) Thinking(62%) Perceiving(44%)
You have strong preference of Introversion over Extraversion (100%)
You have strong preference of Intuition over Sensing (88%)
You have distinct preference of Thinking over Feeling (62%)
You have moderate preference of Perceiving over Judging (44%)
The T is lower than it has been in the past (I think both N and T were a bit over 75%) which I expected from the changes I've experienced being older as the affects of the shadow increase with age but am surprised that the P also dropped... interesting. I don't recall the exact number but it was over 50% when I was younger. I wonder what bearing age and gender have. I/E has also changed greatly. I used to be something like 1% introvert. Maybe its changed so much because I'm retired living in a rural area?Much more reclusive now.
