As a new member I recommend the Paragon test. If you are unsure of an answer, the option is available to put an X in the box. It is the only test I have found to be remotely accurate for my type.
It needs paper and pencil.
take the PLSI
I did the test again and this time, I put an X in the box when I was undecided:
Now the scores were
Introvert 7 - 3 (previously 8 - 4)
Intuitive 12 (previously 10 - 2)
Thinker 8 -2 (previously 7 - 5)
Perception 11 -1 (same as before)
The general trend of me being a card-carrying psychedelic NP still remains, with all the difficulties it causes with the Guardians SJ.
I took the test twice, the second one a few days later with slightly different results. I can't explain why the Intuition changed as it did.
