Impossible Type Combinations

Introduction

How other systems combine with one another is a controversial subject in typology, especially when it comes to Enneagram and MBTI. How many interpret it is that every combination of a types from each system (example being, INFP Enneagram 4, ESTP Enneagram 8, INTJ So7 etc.) is possible because of the nature of the two. Many however, believe that many combinations are impossible to happen. However within this group it is also debated on which combinations specifically are possible or impossible, so the following below is less so a strict line of guidelines to follow, but a general rule of thumb many users go by.

Proponents of the theory that all combinations are possible argue that this is so because different systems measure different metrics. Those who disagree often argue that correlations between type and behavior are what give typology meaning, so the correlations that indicate that a combination is highly improbable should not be taken lightly.
