HOW THIS TEST WORKS
How 16-Type Personality Test works
How version core-v2 is scored, and what it can and cannot tell you.
How it is scored
This test is based on Carl Jung's theory of psychological type. Isabel Briggs Myers and Katharine Briggs later shaped that theory into four pairs of preferences. The same ideas are behind the Myers-Briggs Type Indicator® (MBTI®). This test is not the MBTI and is not connected to The Myers-Briggs Company. MBTI and Myers-Briggs are trademarks of their owner.
The four pairs are: Extraversion or Introversion (where you get energy), Sensing or Intuition (how you take in information), Thinking or Feeling (how you make decisions), and Judging or Perceiving (how you like to live day to day).
Part 1 has 48 sentences, six for each side of each pair. Each sentence adds points to its own side and takes them from the other side. Half of each pair's sentences point one way and half point the other way, so you cannot get a type just by agreeing with everything. Part 2 has 28 pairs of sentences, seven for each pair of preferences. They are meant to sound equally good, so you pick what is true, not what sounds nice. Each choice adds 4.1 points to its side.
For each pair, your two percentages add up to 100. Your type uses the stronger side of each pair. Because Part 2 has an odd number of questions for each pair and its points are not whole numbers, a pair can never end in an exact tie. Research shows these four pairs line up with four of the five main personality traits studied by scientists (McCrae and Costa, 1989).

What it cannot tell you
This test is for learning about yourself. It is not a diagnosis. Do not use it to hire people, choose people, or make health decisions.
People do not fall into neat boxes. Most people are somewhere in the middle on at least one pair. Studies of type tests show that many people get a different four-letter type when they take the test again a few weeks later, mostly because of letters that were close to 50%. So look at how strong each preference is, not just the letter.
The ideas about mental tools, like "Seeing possibilities," come from Jung's theory. They are useful for thinking about yourself, but they have much less research behind them than the four pairs do.
