MBTI

We are all different and unique creatures—every coach knows that—but there are certain personality patterns that have been observed for more than 2,500 years that identify how human beings "tick.” This ancient knowledge may be the closest approximation to a human "user manual" we'll ever have.
Isabel Briggs Myers made this body of knowledge accessible by creating the mother of all self-reporting instruments, the MBTI. It was informed by Carl Jung's psychological theories, the outcome of which is a four-letter "code" based on contrasting personality dimensions. Isabel's contribution was intended as a remedy to World War II. She believed that if we understood each other, peace would reign in the land.
The MBTI is a class B psychological instrument, requiring a particular level of education to administer. It is a serious instrument that has been scientifically researched and rigorously validated. Since its release in 1958, its use has grown and it's now taken by approximately 2 million people every year.
An enormous bank of data has been collected from the assessment—from statistics regarding its accuracy to sociological data identifying common occupations. There are no "right" answers on the Indicator, as every outcome represents normal and healthy ways to be in the world. This distinguishes it from most other assessments and contributes to its enduring popularity. It provides a highly egalitarian approach to exploring human differences.
