Abstract: The invention is a process and apparatus for determining a person's basic personality type. The apparatus includes a card deck having forty different testing cards with each card featuring a written description of a personality characteristic, an associated picture and one of four different color codes associated with a particular type of personality having that characteristic. Five pile labeling cards are also provided. The pile labeling cards are used to define separate pile areas into which the testing cards may be sorted based upon the degree to which the person agrees with the characteristic described on the testing card. A point value is given to each testing card depending on which of the piles it is placed in. The point values of the sorted testing cards are then added together relative to their color codes to determine the user's primary personality type.
