The Jungian Type Index (JTI) is an alternative to the Myers–Briggs Type Indicator (MBTI). Introduced by Optimas in 2001, the JTI was developed over a 10-year period in Norway by psychologists Thor Ødegård and Hallvard E: Ringstad. The JTI was designed to help capture individuals' preferred usage of the psychological functions identified by Carl Jung in his book Psychological Types, such as thinking vs feeling and sensing vs intuition. The JTI's questions and methodology for identifying the preferred functions differs from the MBTI. For example, it eliminates word pairs, which can be troublesome to translate from English into other languages. In many languages, the sentence context frames the meaning of a word, while in English the words themselves may denote more meaning. Source: Wikipedia (en)
