De ongewenste populariteit van typologieën

The unwanted popularity of typologies The unwanted popularity of typologies Typologies are still very popular in organizations, companies and commercial consultancy firms. The assumptions of psychiatrist Carl Gustav Jung, in particular, seem to be in favor again given the many new tests that have been introduced recently. This article discusses the problems with the foundations of Jungian theory (psychoanalysis, paranormal beliefs and metaphysical archetypes), Jungian tests and their test reliability, or lack thereof. Two tests based on Jungian typologies are discussed in more detail: MBTI and Insight Discovery. I demonstrate the widespread use of typologies: various companies, renowned institutes, such as business schools and university departments, as well as governments authorities and municipal services use them and even ask for them. I discuss the reasons for the current state of affairs and recommend to making an effort to turn the tide in favor of evidence-based practice.
