Hi rumel!
I feel like we have entered a web labyrinth! Clicked on the MBTI link you included and clicked on the Take the Test button, which turned out to be another site Personality100.com and took that test... 100 pages later and $30 bucks lighter I am a Thinker! So, I went back and read more at the original MBTI site, answered the four questions and am both ENTP and INTP, also backed up by the 100 pages! The "four questions" Cognitive Style Inventory biases to INTP; Keirsey and P100 to ENTP.
P100 (a full MBTI test - 4 web pages of questions) also rated my "Openess" (vrs Structure) as moderate tending to high (80%) which is probably why I am here and Aneros etc. and and contemplating this next variant!
However, as someone who is scanning and writing about the increasing dominance of narrative and storytelling as foundational modes of communications of all sorts, in all kinds of silos of specialization, I was fascinated to stumble upon PMAI and their Archetype Indicator system and Test
About the Pearson-Marr Archetype Indicator Instrument - CAPT.org "What is your life story and what roles do you play?" being the fundamental idea...
Haven't yet, but will probably try this too for fun!
all the best
