The MBTI® assessment is a psychometric tool that gives you insight into what makes you you. By developing a clearer sense of self-awareness and awareness of others, you’re able to better frame decisions, reduce miscommunication, and understand personal needs more effectively. And that’s a good skill to have.

All About the Myers-Briggs® (MBTI®) Assessment
The MBTI® is a tool to enrich people’s understanding of themselves and others. With it, we aim to inspire the world, one world at a time. From Stephen Colbert to business leaders, Oprah’s interview with Nicole Kidman to universities around the world, people are fascinated with the Myers-Briggs Type Indicator, aka the MBTI. But what is it, really? A fun personality assessment? Or a serious business tool? It’s both. And it’s a scientifically-validated psychometric assessment.

The MBTI® assessment was not designed to describe every aspect of personality. It focuses on four preference pairs:
- Extraversion–Introversion (E–I): From where you get your energy
- Sensing–Intuition (S–N): What information you prefer to gather and trust
- Thinking–Feeling (T–F): The process you prefer to use in making decisions
- Judging–Perceiving (J–P): How you deal with the world around you
This isn’t to say that everyone who has a preference for Sensing, for example, is alike in every aspect. Personality is more complex than that! However, sorting people into the 16 types based on certain aspects of personality can illustrate how people are alike and how they are different. Looking at personality in this way is useful for certain purposes.
No personality assessment measures all aspects of personality or completely describes an individual. All personality assessments are using a model (some based on theory, some lacking a theory) to summarize large groups of individuals in a relatively small number of useful descriptors.

No. The genuine MBTI® assessment is copyrighted and only accessible by individuals who are MBTI certified and available through MBTIonline.com, which allows you to complete the assessment and provides a self-directed interpretation.
The MBTI assessment is backed up by 75 years of research and continues to be refined and updated. The assessment also has considerable evidence for its reliability and validity, much of which is reported in its manual. You may find free questionnaires that are based on Jung and Myers and Briggs' theory and that talk about the four preference pairs. But free personality assessments typically lack evidence showing they are reliable and valid measures.

Yes. Four editions (1962, 1985, 1998, 2018) of its manual have been published, providing a wealth of research-based evidence on its reliability and validity. The manual also explains the theory behind the assessment, its construction, and the data collection and analysis of the scales.
It is well established that the Myers-Briggs® assessment meets all requirements for educational and psychological tests, and you can access information on its validity and reliability. Scientists have been scrutinizing it for more than 50 years, and it has been cited and reviewed thousands of times (a Google Scholar search for “MBTI” found over 31,000 records). The Center for Applications of Psychological Type (CAPT) also publishes helpful information on the reliability and validity of the Myers-Briggs assessment.
For more information, Dr. Rich Thompson, The Myers-Briggs Company’s head of research, deconstructs common criticisms of the MBTI assessment. Also see taking on the MBTI sceptics to view another presentation (scroll down the page that opens to access the video).

When psychologists or practitioners evaluate a psychometric test or questionnaire, they usually ask two main questions: “Is it reliable?” and “Is it valid?” On both of these criteria, the MBTI assessment performs well. Reputable psychometric tools have been developed through years of rigorous research, and The Myers-Briggs Company makes these research findings available via the MBTI® Manual for the Global Step I™ and Step II™ Assessments (Myers, McCaulley, Quenk, & Hammer, 2018). This manual is provided to all certified practitioners as part of their certification materials. Major findings are also published in data supplements that can be downloaded from The Myers-Briggs Company website for the current commercial version and prior commercial versions.
In addition, there are many articles by independent researchers in established journals. Interested parties can find hundreds of these on a free searchable database published by the Center for Applications of Psychological Type (CAPT), called Mary and Isabel’s Library Online (MILO), at www.capt.org/MILO.
Finally, the MBTI assessment meets the stringent requirements for psychological assessments in psychology societies around the world (e.g., the British Psychological Society, The Health Professions Council of South Africa, and Sistema de Avaliação de Testes Psicológicos in Brazil). Furthermore, the MBTI assessment has been voluntarily submitted to organizations in the United States for independent review such as those provided in Buros Mental Measurements Yearbook, in Psyctests by the American Psychological Association, and in the Comprehensive Guide to Career Assessment (7th ed.) published by the National Career Development Association (NCDA). Note that the American Psychological Association (APA) does not approve or disapprove the use of assessments in the United States. Instead, the APA provides ethical guidelines that put the onus on the users of assessments to evaluate their reliability, validity, and appropriateness.
