Astrology is a set of systems used for attempting to better understand the past and present and for predicting the future based on the idea that there’s a relationship between the position of stars and planets in the sky and events in the life of a person. A system of astrology can be as basic as the newspaper horoscope, which categorizes all people into 1 of 12 categories. Across most of human history, astrology was widely considered a scholarly discipline. It was accepted as scientific fact in government and academia from early civilization up to at least the 17th century.
The Myers–Briggs Type Indicator (MBTI) is a psychometric assessment based on a simple questionnaire derived from the idea that there are 4 and only 4 principal psychological functions by which people experience the world. The intent is to measure and predict how individuals perceive the world and make decisions, categorizing all people into 1 of 16 categories. The Myers-Briggs is used by 89 of the Fortune 100 companies and is very popular in businesses around the world; however, it has been criticized as having methodological weaknesses, poor statistical validity, and low reliability.
The Myers–Briggs assessment is no better than astrology, and potentially much worse.
