In an attempt to work out how people view themselves and the world around them, introspective self-reporting questionnaires have been used by psychologists and psychotherapists since the times of Karl Jung. The Myers-Briggs personality test was developed from these original methods to form a structure around which people would be able to identify as one of sixteen distinct personality types. These are made up of four so-called dichotomies each which can be interpreted in two ways, thereby allowing for a total of sixteen possible combinations that correspond to the aforementioned personality types. The Myers-Briggs personality test was developed in the Second World War and after it to allow psychologists to determine the personalities of individuals according to the examples outlined in the Myers-Briggs personality indicator.
