The enneagram and MBTI types are complementary. The cognitive function structures of MBTI express ways of interacting with information. They provide elements on the ‘how’ of a behaviour. The enneagram learns from the background of a person and provides elements on the ‘why’ of a behaviour. Based on these definitions, we can conclude that all combinations are possible. But since the ‘how’ and the ‘why’ of a behaviour are often linked, there are combinations which are more common than others. We have compiled this table with statistics based on 4682 results, in which the MBTI types were also stated.
