Mere Orthodoxy (which you really should be following) has guest posted a piece of mine entitled ‘The Dangers of Appealing to Personality Type’. Within it I make a case for a sceptical approach to personality tests such as Myers-Briggs.
Everyone wants to believe that the mere possession of a particular personality type gives them some sort of privileged access to or claim upon reality, society, or set of skills. Keirsey’s Temperament Sorter, closely associated with the MBTI, will assign you an identity on the basis of the result of your personality test. Here everyone’s a winner. It will designate you as an ‘inventor’, a ‘mastermind’, a ‘fieldmarshal’, a ‘champion’, a ‘healer’, or an ‘architect’ on no more sure of a basis than the fact that your personality skews in a particular direction. This is all entirely independent of anything that you have ever achieved or skill you have developed. ‘English major’ may not yet be one of Keirsey’s temperaments, but Guyton employs it as if it were. When I discover that I am an ESFP or an INTJ, I can enjoy a sense of an innate superiority, entirely independent of actual work and achievement, which the world must acknowledge and validate. I am here reminded of Lady Catherine de Bourgh’s remark concerning the piano in Pride and Prejudice: ‘If I had ever learnt, I should have been a great proficient.’
Psychometric tests such as the MBTI promise to reveal deep truths about our personalities. Like the Sorting Hat in the Harry Potter books, through some mysterious alchemy, they will discern our true nature and assign us a named identity accordingly. The scientific basis of the claims of many psychometric tests such as the MBTI is highly dubious and their effectiveness probably has more than a little to do with such things as the Forer effect.
Nevertheless, personality typing can easily become powerfully constitutive of people’s sense of identity, as they start to think of themselves as their personality type in a fairly uncritical manner. The appeal of such tests is quite explicable: they offer a measure of resolution to the existential discomfort of the question ‘who am I?’, a question which is probably pressed upon us with greater urgency than ever before. While such a test may be an improvement on diverting online quizzes promising to reveal which characters I might be in various fictional universes, at least I do not go through life believing that Gandalf-likeness is a crucial key to my identity.
