The Myers-Briggs Personality Type Indicator (MBTI) is the most uses psychology assessment inventory that is designed to help individuals identify and understand their type of personality, preferences and strength. Jung’s discovery on the types of psychological theories influences Isabel Myers and her mother Katherine Briggs to develop an indicatory that would help people identify their personality type and understand themselves better hence live happy and healthy lives. Myers and Briggs developed a set of questions on the inventory that revealed the personality of an individual. MBTI have questions that allow people to explore their compatibility with others, strength, weakness, career preferences, likes, and dislikes. MBTI has four dichotomies that include, extraversion (E)- Introversion (I), Sensing (S)- Intuition (I), Thinking (T)- Feeling (F), and Judging (J)-Perceiving (P). This gives a total of sixteen personalities with each indicated by a four-letter code. For example, ISFP is a personality type. It is critical to note that no personality type is better than the other because they are all equal. The goal, therefore, is to understand and appreciate the different personalities in people and help develop a better relationship with those around us.
MBTI is a reliable assessment tool used by many psychologists. MBTI gives a score of between 75% and 90% when an individual repeats the test. MBTI has good scores and reliabilities in different ethnic and age groups. MBTI has high validity scores. The four pairs of dichotomies and the combinations of the various preferences enables people to accurately predict and understand the behaviours, values and attitudes of people. Evidence of validity is seen when people resonate with the results of the personality type gotten at the end of the sixteen questions.
