What’s Its Scientific Basis? Is Personality Permanent? Should Companies Screen Hires with it?


Sunnyvale, Calif., May 19, 2020 -- The Myers-Briggs Type Indicator® (MBTI®) instrument is the world’s most popular personality assessment, used by the majority of the Fortune 100 as well as millions of individuals each year to improve numerous aspects of work and life. Nevertheless, the instrument has been the center of many debates, and there’s a lot of confusion surrounding it.


To clarify things, The Myers-Briggs Company, a Certified B Corp, just launched MBTI Facts, an in-depth online resource with answers to all the most common and important questions about the assessment.


“There’s a lot of false information out there about the MBTI assessment,” said Jeff Hayes, President and CEO, The Myers-Briggs Company. “It’s important to get the right answers with the evidence to back it up. So, we put together a comprehensive resource for the most trusted, most up-to-date information on the MBTI assessment.”


As popularity soars, so does misinformation

The prevalence of the MBTI instrument is at an all-time high. People are now using it for everything from corporate leadership training to dating. And with so many pop-up sources offering knockoff ‘personality quizzes’, how can you be sure the version you’re taking provides genuine MBTI insights and not unscientific, inaccurate and unreliable information?


MBTI Facts: Answering Your Questions About the MBTI, accessible at, offers comprehensive answers to questions such as:


  • What’s its scientific basis? And is it reliable and valid?
  • What’s the history behind the MBTI assessment and its creators?
  • Who uses it, and what do they use it for?
  • Can it be used for selection or hiring?
  • Does it describe my whole personality?
  • How is it related to Carl Jung’s theory?
  • Is it available for free online?
  • Is personality permanent, or does it change over time?
  • Does the MBTI assessment put people into a box?


In addition to shorter answers, the MBTI Facts page lets you dive deeper into responses and research collated by The Myers-Briggs Company’s experienced organizational psychologists. For a majority of the answers, links to outside research and resources supplement basic information, allowing users to read as much or as little as they’d like.
