When it comes to merging these two major typology systems: Myers-Briggs and the Enneagram, there is no “one size fits all” method. Truly any type combination is possible making not just 16 personalities or 9 personalities, but 144 different expressions!
Each typology system offers incredible personal insight but is incomplete on its own: where Myers-Briggs delves deeply into cognitive functions and how intricately the brain learns and processes information, the Enneagram offers insight into emotional health, childhood experiences, and basic driving human instincts. Using these typology systems in conjunction will not only give you a better understanding of yourself as a person, but will help shape your relationships and guide you toward a more successful and happy future!
Below you can find a description of the three common Enneagram types for ISTPs.
ISTP Five “The Investigator”
ISTP Fives are more cerebral than other ISTPs. They enjoy their alone time and are typically more protective of the belongings they have accumulated over time. They enjoy learning and taking in new information (via books, e-books, videos, podcasts, etc.). ISTP Fives will take a long time to make decisions and shouldn’t be rushed when deciding on major purchases or life choices. These ISTPs are intelligent, protective, perceptive, secretive, and love their space.
ISTP Seven “The Enthusiast”
ISTP Sevens love of freedom and need for adventure. These ISTPs will probably be more in touch with their auxiliary Extroverted Sensing/Se function as they enjoy experiencing the true breadth of their exterior environment. These ISTPs are usually adrenaline junkies who love taking risks in a physical way. They appreciate their freedom and want to be left alone to test the limits of what’s humanly possible. ISTP Sevens should take time to nurture and engage their dominant Introverted Thinking/Ti function so that their risks can be well-calculated beforehand.
ISTP Nine “The Peacekeeper”
ISTP Nines often have a “live and let live” mentality and may be more in touch with their inferior Extroverted Feeling/Fe function than other ISTPs. It’s possible that these ISTPs find themselves in more stressful situations than other ISTPs and this causes them to land “in the grip” of their inferior function more often. If an ISTP is in the grip of their inferior Fe, they may feel that pulling away from others will lead to uncomfortable loss or separation. ISTPs Nines should practically engage their Introverted Thinking function to help them feel more personally grounded.
