This is quite interesting, I suggest taking it and doing some personnal research if you're interested in self exploration. If not, it will at least peak your curiousity for a bit. Post your results after and feel free to discuss amongst other results. I've taken the questionnaire several times, and also have tried multiple similar "16 types" before with the result of an INTJ. Personality test based on Jung and Briggs Myers typology This assessment is a psychometric questionnaire designed to measure psychological preferences in how people perceive the world and make decisions. These preferences were extrapolated from the typological theories proposed by Carl Gustav Jung and first published in his 1921 book, "Psychological Types" (1923). The original developers of the personality inventory were Katharine Cook Briggs and her daughter, Isabel Briggs Myers.
