Myers-Briggs Type Indicator®

Over the past 70 years, the Myers-Briggs Type Indicator® (MBTI®) instrument has helped millions of individuals throughout the world gain awareness about themselves and how they interact with others. The MBTI® instrument enables personal transformation by giving people a powerful tool for improving how they communicate, learn and work.

In developing the MBTI® instrument, Isabel Briggs Myers and her mother, Katharine Briggs, aimed to make Carl Jung’s theory of psychological type understandable and useful in people’s everyday lives.

The essence of the theory is that much seemingly random variation in behaviour is actually quite orderly and consistent, owing to basic differences in the ways individuals are oriented toward the external world, take in information and draw conclusions about what they perceive.

Please take a moment to view this short video to learn about the MBTI® instrument.


    • The MBTI® instrument is close to the silver bullet for business. It lets you align the key elements… customers, staff and management. We have used the MBTI® instrument in sales training, sales, product development, service process, marketing and organisational development every year for the last 12 years.

Today, the MBTI® instrument is the most widely used personality assessment in the world. More than 2 million assessments are administered to individuals annually - including employees of many Fortune 500 companies. Organisations have selected it as the personality instrument of choice across their training and development programs because it provides a common language for appreciating interpersonal differences.

Type and the gig economy: A research study from The Myers-Briggs Company

Type and the gig economy: A research study from The Myers-Briggs Company was designed to investigate how personality and other factors relate to the differences between gig and ‘regular’ jobs, the reasons why someone becomes a gig worker, types of gig work done, and views on gig jobs. For gig workers, this information could be very useful in making them aware of their likely strengths and possible blind spots, and in deciding whether gig or other freelance work was right for them. For organizations, this could be the key to managing their gig workers and contractors more efficiently and effectively. The aim of this study was to develop straightforward guidelines that could be used by both.
