The most popular form of personality test is the Type Test, of which the Myers-Brigg Type Indicator (MBTI) is the most popular. These tests are "founded in Jungian
typology" and break down personalities into discrete types. According to the MBTI, we all exist in four either/or binaries. You are either extroverted (E) or introverted (I), sensing (S) or intuitive (N), thinking (T) or feeling (F), judging (J) or perceiving (P). Our unique combination of these four factors adds up to create one of 16 personality types onto which some tests add the modifier of either turbulent (T) or assertive (A), resulting in 32 total variations. Although the official MBTI
may cost upwards of £40,
there are many free tests that directly pull from the MBTI model. The one I test myself with, which no doubt you have done too, is 16Personalities
, one of the most popular and wide-reaching internet tests (with 214,248,607 tests taken at the time of writing).
