My name is LJ Rauternbach and I have been using the Keirsey Temperament Sorter (KTS) since 1995 and updated my skills by attending and successfully completed the KTS-II training in London in 2007. The KTS-II Temperament Sorter is a well established tool, used within most of the Fortune 200 companies worldwide. These include Coca Cola Company, IBM, FORD, Price Waterhouse Cooper, GAP, UPS, Siemens, US Army, Yale University etc. Your Personality is made up of two elements. Temperament and Character. Temperament is the bit that does not change and is like the hardware in a PC, while Character is the bit that does change with experience, culture, values etc, like the software in a PC. The KTS-II looks at a persons temperament and then categorises the person in one of 4 groups (each with 4 types). Each type has a unique way of speaking and doing that separates them from each other. This unique way of speaking and doing enables a person to have a natural intelligence in specific fields e.g The Artisan is naturally gifted in tactical skills, where the Idealists are gifted in diplomacy etc. The KTS-II as a theory has been developed over more than 50 yrs. However, this is not new at all. In fact, there is evidence recorded over the past 2000 years by observers like Plato, Aristotle even Ezekiel in the Bible, that man naturallly falls in 4 unique categories. With the dawn of modern psychology at the turn of the century Freud for instance focused on “pleasure” as the highest motivation of life while Maslow for instance contradicted Freud with his hierarchy of needs claiming that “Self-Actualisation (to know thy self)” is the highest form of living. Looking through the paradigm of temperament theory, this makes perfect sense. Freud would seek pleasure because he was an Artisan, and Maslow would seek self-actualisation because he was a Idealist.
