Myers-Briggs Type Indicator

The Myers-Briggs Type Indicator (MBTI) is the Jungian self-report questionnaire, authored by the Statesian mother-and-daughter team Katharine Briggs and Isabel Myers in 1944,1) and published through “The Myers-Briggs Company” (CPP, Inc.) since 1975.

Despite the instrument being widely regarded as faulty pseudoscience by psychologists,2)3) it has remained in use by businesses, federal agencies, and universities4)5)6) despite concerns being raised over possible biases and discrimination.7) Furthermore, the instrument has seen a surge in popularity amongst East Asian countries, like China8)9) and South Korea,10)11) to the point where it has become a dating tool.12)13)14)


In short, the indicator uses four binary dichotomies to categorize people into sixteen personality types which use a four-letter initialism of said dichotomies as shown below.

  • Extroversion (E) or Introversion (I)
    The “attitude” function, which assesses how you typically exert and gather energy.
  • Sensing (S) or Intuition (N)
    The “information gathering” function, which assesses how you interpret new information.
  • Thinking (T) or Feeling (F)
    The “decision making” function, which assessing what you do with that information.
  • Judging (J) or Perceiving (P)
    The “lifestyle” function, which is more complex since it's mostly for further categorization.

Finding a personality type

The official methods of finding your personality type is either reading through the materials or completing a paid questionnaire at MBTI Online, but you can probably imagine that these options aren't really used. Instead, most people usually end up taking one of several MBTI-inspired tests online, listed below, that kinda dodges the copyright that surrounds the instrument.


  • As usual, its use of the Barnum–Forer effect and confirmation bias should be noted.
  • It's also important to note that personalities can change, despite what the official organization says,17) so don't allow yourself to become a victim of labeling theory and pigeonhole yourself.
    • This can especially be harmful if you've ever looked into the ideal careers for each type, like, some of these personality types get paired with the worst careers and job choices.
  • Despite being controversial within the MBTI community, there's actually fan art of the 16Personalities.
  • For those curious, the curator used to fall under INTP–INTJ, but has since grown into an INFP.
The first MBTI handbook was released in 1944 as the Briggs Myers Type Indicator Handbook, before it was renamed to the Myers-Briggs Type Indicator in 1956. The first MBTI manual was released in 1962.
