Isabel Briggs Myers was an American writer who co-created the Myers–Briggs Type Indicator. This tool is known as the MBTI. It is one of the most frequently used personality tests in the world. Currently, over two million people complete the questionnaire every year. The MBTI is designed to assess an individual's personality type. It helps people understand how they perceive the world and make decisions. While widely popular, the MBTI is often described as a pseudoscience. This means many academic researchers in psychology do not widely endorse its validity.

The development of the MBTI was a long and detailed process. Myers used the psychological theories of Carl Jung as her foundation. Jung originally identified three pairs of psychological preferences. These were Extraversion and Introversion, Sensation and Intuition, and Thinking and Feeling. Myers spent twenty years researching these concepts with her mother, Katharine Cook Briggs. During this time, she added a fourth pair of preferences called Judging and Perceiving. By combining these four pairs, the test can sort people into sixteen distinct personality types. This systematic approach turned abstract psychological ideas into a concrete paper survey.

Myers's interest in personality types was driven by several personal and historical factors. She was inspired by her marriage to Clarence "Chief" Gates Myers. The differences in their psychological types motivated her mother to study human actions. During World War II, Myers read an article titled "Fitting the Worker to the Job." This article sparked an epiphany regarding the need for a people-sorting instrument. She believed such a tool would be vital as U.S. involvement in the war grew. She wrote about this new purpose in a letter to her mother.

Before her work on psychology, Myers was a successful mystery novelist. In August 1928, she entered a contest held by McClure's magazine. Her novel, "Murder Yet to Come," won the contest. This victory included a $7,500 cash award and a contract for another book. She fulfilled this contract by writing "Give Me Death," published in 1934. However, this second novel received harsh treatment from critics. Her early career shows a different side of her writing talents before she focused on personality theory.

Myers conducted significant practical research to refine the MBTI. In 1945, the dean of the George Washington School of Medicine granted her permission to test students. Myers and her mother applied the MBTI to approximately 5,500 first-year undergraduates. She studied the results for many years to find specific patterns. She specifically looked at the differences between successful students and those who dropped out. This helped her understand how personality types might relate to academic success and behavior.

In 1975, Myers helped expand the reach of her work by co-founding the Center for Application of Psychological Type, or CAPT. She founded this organization alongside Mary McCaulley. CAPT is a non-profit organization based in Gainesville, Florida. It is run by the Myers & Briggs Foundation. The center's motto is "Fostering human understanding through training, publishing, and research." CAPT maintains the research and application of the MBTI today. They also publish their own research in the Journal of Psychological Type.

To support ongoing study, the Isabel Briggs Myers Memorial Research Awards were established. These awards are given twice a year to researchers. Each award provides $2,000 to up to two people. These funds help further the study of the MBTI and psychological research. However, some experts raise questions about the independence of this research. Because much of the validity research is produced by CAPT, some suggest there may be a conflict of interest. This remains a central part of the discussion surrounding the MBTI's scientific standing.

Myers's legacy continues through her many publications and her son, Peter. She co-authored the book "Gifts Differing: Understanding Personality Type" with Peter. This book explains how the sixteen personality types affect marriage, careers, and the meaning of life. She also wrote "Introduction to Type," which describes the theory and applications of the MBTI. Even though academic psychologists debate its accuracy, the MBTI remains a massive global phenomenon. It continues to be used by businesses, coaches, and psychologists everywhere.
