MBTI
16 Personalities
In personality typology, the Myers–Briggs Type Indicator (MBTI) is an
introspective self-report questionnaire indicating differing
psychological preferences in how people perceive the world and make
decisions. Despite its popularity, it has been widely regarded as
pseudoscience by the scientific community. The test attempts to assign a
value to each of four categories: introversion or extraversion, sensing
or intuition, thinking or feeling, and judging or perceiving. One letter
from each category is taken to produce a four-letter test result, such
as "INTP" or "ESFJ".
