I've taken this test several times over the last couple of years, and I've registered as INTP each time.
I'd also like to enter in the
OCEAN (or Big Five) personality test, which is much more commonly used in psychology for testing (note: you don't need to answer all of the questions below asking about your age, country, etc). Carl Jung's archetypes are more interesting than necessarily scientific. Jung, on top of that, was kind of fucking nuts, and I say that as someone who finds his work fascinating. The Myers-Briggs (which is what we're all taking here) does have some amount of merit, but the OCEAN/Big Five is generally more reliable and valid. It also gives a real middle ground to answer things as opposed to converging upon a yes or no answer.
The answers of the Big Five are determined by a methodical factor analysis. Essentially, psychologists gathered an enormous amount of personality traits through experimentation and observation. They then proceeded to combine ones that had similarities, breaking it down gradually until they ended up with only five left. There are even other variations with different amounts of personality traits, but the one I linked is the most common. The personality traits are
Openness,
Conscientiousness,
Extraversion,
Agreeableness, and
Neuroticism. The Myers-Briggs forms from Jung's archetypes, which I personally like to think of as more the philosophy of psychology as opposed to genuine science. Again, I don't mean to discredit it, but it has its flaws.
My Big Five:
95th percentile in openness, 6th percentile in conscientiousness, 70th percentile in extraversion, 94th percentile in agreeableness, 27th percentile in neuroticism. I'm generally more neurotic and less extraverted, but I'm in a good place irl at the moment, so I'm naturally trending that way.
