Realizing the impact awareness of Jung's type theory could have on mankind, Katherine Cook Briggs and her daughter Isabel Briggs Myers developed a questionnaire in the first half of the 20th century that has been tested for validity and reliability since then. The MBTI® today is available in over 30 languages and is the world's most trusted personality type assessment. Guidelines of ethical use require the results to be facilitated by a certified professional.
The Step I questionnaire comprises 93 items, resulting in a four-letter Type out of a possible 16 combinations.
Step II questionnaire comprises 144 items, resulting in a four-letter Type out of a possible 16 combinations, as well as providing insights into five different facets on all attitudes and functions for how each person may differ from another of the same Type.
The tool is not theory:
Your psychological type is more than a four-letter choice between two options. Your type is dynamic, there is a hierarchy to your functions, and the patterns described by your whole, best-fit type are much richer than what you see at first glance. Therefore, there is no "boxing in" of people, rather the MBTI offers a short-hand explanation of your preferences.
The tool has specific purpose:
MBTI results offer tremendous insight into how you approach life and work, and how you might structure your personal and professional development path. It is not suitable for personnel recruitment or match-making.
Don't force your answers:
If you think one side "sounds better", ask your facilitator to explain the Jungian meaning. For example, Thinking does not mean cold or unfeeling, and Perceiving is not the same as procrastinating.
Careful about "typing" others:
People are complex, and just because they behave one way at work does not mean that is their actual personality type preference. We all have access to all functions at all times, it's the order in which we prefer them that gives insight into our patterns.
