Myers-Briggs Type Indicator

June 30, 2016

When people learn that Healthymemory (HM) is a psychologist, they frequently tell me they know about the Myers-Briggs Type Indicator (MBTI) to indicate to me that they, also, know about psychology.  What they do not realize is that they are indicating to me that they have a profound ignorance of psychology.  First of all, the developers of the MBTI, Katharine Cook Briggs and her daughter, Isabel Briggs Myers, were not psychologists, nor did they have any psychological training.  Moreover, they developed their theory from Carl Jung’s writings in his book “Psychological Types.”  Carl Jung was psychotherapist in the early days of psychiatry.   Today, he is mainly of historical interest and his impact on current psychiatry or personality theory is small.  Psychometric tools have metrics for assessing utility.  Two standards for assessing psychometric tools are validity (does it measure what it purports to measure ) and reliability (are the measurements consistent).  The MBTI fails on both metrics having poor validity and poor reliability (It will sometimes give different results for the same person on different occasions).

Nevertheless, the MBTI is quite popular in the business sector and in government, including the intelligence agencies.  Moreover, if HM informs a client that the MBTI is garbage, they are still likely to insist on its use.  So, so-called hard nose business people would rather use something that is known and is worthless that they know about, rather than some other tool with measurable value.

When agencies are asked why they find the MBTI useful, you usually get responses such as Harry is always late responding, and now I understand why.  Or Fred does sloppy work, and now I understand why.  For some reason they think that a label implies understanding.  Frankly ,when HM worked in a group, he quickly learned who was reliable,  who was timely, and so forth, and planned his management accordingly.  HM believes that these people who think the label told them something were already aware of the idiosycrancies of their staff.

The only apparent redeeming value of the MBTI is that it has some correlation with four of the Big Five personality traits: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism.  These Big five traits are somewhat contentious.
One of the problems with personality traits is that individuals can exhibit different traits in different circumstances.  Moreover, these traits are not fixed, they can change.

Consequently, HM would steer you away from these Big five traits and towards Davidson’s Six Dimensions of Emotional Style.  They are resilience, outlook, self awareness, social intuition, sensitivity to context, and attentional style.  HM would argue that resilience, the ability to bounce back from adversity, is clearly the most important of these attributes, bu resilience is absent from many personality characterizations.

A primary advantage of Davidson’s approach is that provides a means to grow and adapt.  That is, it employs a growth mindset as opposed to the fixed mindsets provided by previous personality type characterizations.
