The first personality test was developed by Katherine Cook Briggs and her daughter Isabel Brigg Myers during World War 2. The aim of the test was to help women who were entering the industrial workforce for the first time to identify the sort of war-time jobs where they would be "most comfortable and effective". Today, such tests are used for individual and relationship counseling, career planning, employment selection and development.

The iKnowThyself personality test aims to help individuals as well to achieve success in the areas of self development mentioned in the above. As there are 16 types of possible personality combination, the iKnowThyself personality test breaks down and help the individual to discover which type he/she belongs through a series of description that were developed for psychological type testing.

Do take some time to carefully read the description and think about which is the most relevant to your own personality. After all, knowing your own personality type is the key to a successful life. Dr Melaine Calkins is a pen name.
