The history of MBTI®
One the world’s most used assessment tools
The Myers-Briggs Type Indicator (MBTI®) emerged in the United States during the early to mid 20th century, developed by Katharine Cook Briggs and her daughter, Isabel Briggs Myers.
Their interest in personality type theory was sparked when Briggs met Isabel’s future husband, Clarence Myers. She noticed that Clarence Myers viewed the world in markedly different ways, which led her to initiate a comprehensive study of literature on temperament and personality theory.
During World War II, the urgency and relevance of their project increased dramatically. Myers believed that greater understanding of individual differences could foster improved cooperation and reduce conflict, particularly in a post-war context. Her conviction was that a world in which people understood each other would be a better place for all.
Driven by this vision, Myers was determined to create a practical tool that could provide individuals with insight into their psychological preferences. This ambition resulted in the development of the MBTI. She spent over two decades meticulously crafting and validating questions for the type indicator, as well as refining the underlying theoretical framework.
She spent the next 20 years developing questions and validating the instrument and the theory. The MBTI instrument was first published in 1962. Today, the Myers-Briggs Type Indicator – MBTI continues to be one of the most widely used psychological tools for understanding personality differences and improving workplace collaboration.

What is Jung’s influence on the MBTI® theory?
Carl Gustav Jung published Psychological Typesin 1921, introducing foundational concepts in personality theory. When Katharine Cook Briggs read Jung’s work, she recognised significant parallels with her own ideas. Both Briggs and her daughter Isabel Briggs Myers found Jung’s theories so valuable that they were inspired to further develop and expand upon them.
Their goal was to make Jung’s insights into personality type more accessible and practical for a wider audience. Through their efforts, they created the Myers-Briggs Type Indicator (MBTI®), which synthesises Jung’s original concepts with their own research, providing a practical framework for understanding individual differences.
