Validity of both Forms M and Q has been examined through behavioral observations, exploratory and confirmatory factor analyses, correlations with related measures, and even brain scans. For instance:
- Introverts spend significantly more time than Extraverts conducting “heads down” work, while Extraverts spend significantly more time doing work in open areas (Schaubhut, Thompson, & O’Hara, 2008)
- INtuitives express significantly greater interest in Artistic occupations than Sensors (O’Hara, Thompson, Donnay, Morris, & Schaubhut, 2006)
- Thinkers score significantly higher than Feelers on dominance, while Feelers score significantly higher on nurturance (Quenk, Hammer, & Majors, 2001)
- Judgers score significantly higher than Perceivers on order, while Perceivers score significantly higher on change (Quenk, Hammer, & Majors, 2001)
In fact, a research database maintained by the Center for Applications of Psychological Type (CAPT) lists more than 10,000 articles, books, and chapters relevant to the study of psychological type.
Today, the MBTI assessment is available in 21 languages, with more translations and international research efforts in development. With its long and distinguished history, it continues to be used by people around the world to improve individual and team performance, explore careers, and reduce workplace conflict. Through these and other applications, the MBTI assessment is playing a part in the vision laid out by Briggs and Myers, helping people understand and appreciate themselves and others.
