The Memorado personality type test is similar in its approach to a personality test first developed by Katharine Briggs and Isabel Briggs Myers. It is a psychometric test designed to measure psychological preferences in how people perceive the world and make decisions. The test is frequently used in the areas of pedagogy, group dynamics, employee training, leadership training and personal development.Every personality is based on four preferences: Where, primarily, do you prefer to direct your energy? E or I (Extroversion or Introversion) How do you prefer to process information? S or N (Sensing or iNtuition) How do you prefer to make decisions? T or F (Thinking or Feeling) How do you prefer to organize your life? J or P (Judgment or Perception) The interaction of two, three, or four preferences are known as type dynamics, and when dealing with a four-preference combination it is called a type. In total, there are 16 unique types with each having its own descriptive name such as ENTP or ISTJ.
