The Myers-Briggs Type Indicator® (MBTI®) instrument is a personality assessment designed to be useful in everyday life. It helps people identify four basic personality preferences that combine to form their individual MBTI personality type. Understanding your MBTI results can help you understand and appreciate the natural differences in the ways people think, communicate, and interact—differences that can be the source of much misunderstanding.
Drawn from Carl Jung’s theory of psychological types and refined through decades of research, the MBTI instrument has been used for more than 70 years to establish greater self-knowledge and interpersonal understanding among people of all ages and backgrounds. It has been translated into more than 20 different languages for use around the world.
Our goal is to deliver a highly accurate, research-backed experience that provides valid and reliable results, as well as an evolving learning tool set that includes actionable tips.
We recognize that there are personality test alternatives out there. MBTI is designed for people who are looking for something beyond a casual personality quiz. It was created by CPP, Inc., the exclusive publisher of the MBTI assessment, to provide a comprehensive exploration of personality type that is personally relevant to each user. CPP, Inc. is continually investing in research, optimizing the assessment to increase reliability and relevancy, and are always looking for new insights to share with our users.
Our pricing ensures that we can continue to work on and deliver an experience that reflects our values and ambitions while bringing the power of the MBTI assessment to individuals around the world.
The MBTI instrument was the first tool to describe healthy, normal personalities rather than abnormal ones. It identifies 16 personality types that are all equally valid and healthy. Knowledge of psychological type helps people better understand themselves and each other, resulting in more effective and satisfying human interaction.
No other personality assessment is backed by as much research and as many years of use as is the MBTI instrument, which has been taken by millions of people worldwide. The MBTI instrument is continually updated through ongoing research to ensure its ability to identify meaningful personality differences.
Yes. The instrument’s reliability has been proven statistically, and its validity has been firmly established in hundreds of separate studies. Reliability refers to whether the results are consistent: Do people tend to reply to the items in the same way when they take the assessment later, and do they tend to get the same four-letter type? Can you count on the results? Validity refers to the instrument’s ability to identify psychological types according to Carl Jung’s theory.
The MBTI instrument helps people discover and understand their personality type by identifying their preferences between four pairs of opposites. Each of the opposite preferences is represented by a specific letter:
Technical information on the research and psychometric properties underlying the MBTI instrument are published in the MBTI® Manual and in other scientific publications. Recent updates can be accessed at www.cpp.com/mbtivalidity.
The MBTI® instrument has been the subject of thousands of research projects studying the links between personality type and different aspects of life.
There are two organizations in the United States that assist with research related to the Myers-Briggs Type Indicator® (MBTI®) instrument and those are:
CPP, the publisher of the MBTI assessment, reports and support materials, and The Center for Applications of Psychological Type (CAPT), a nonprofit organization founded in 1975 by Isabel Briggs Myers and a Clinical psychologist, Mary H. McCaulley, Ph.D.
CPP offers reduced prices for researchers who meet certain requirements. To learn more, visit the CPP research division at www.cpp.com/contents/research_grants.aspx
CAPT offers some research consultation and assistance. If you are requesting help for a research project, please forward as much detailed information as possible related to your research questions and design. Please send these inquiries to firstname.lastname@example.org
