Enneagram Compatibility: Investigator Type 5 with Peacemaker Type 9

Enneagram Type 5 Observers/Thinkers/Investigators are typically introverted, curious, analytical and insightful. Enneagram Type 9 is called the Peacemaker or the Meditator because of their focus on harmony and their mellow, go-with-the-flow attitude. Here we explore the compatibility of an Enneagram Type 5 with a Type 9 and what the relationship looks like when it is in balance and when it starts to spiral downward.


Enneagram Type 5:9 When In Balance

Freedom and independence to pursue their personal goals are foundational elements of the Investigator (5) and Peacemaker (9) partnership. Both are committed to each other’s happiness and dedicated to the relationship itself. From this base, this couple has a mix of balancing and similar traits.

Investigator (5)s are insightful, observant, resourceful, calm, objective and trustworthy. Their thinking is rational, logical and methodical, and these traits are useful to their Peacemaker (9) whose thinking can be more circular and emotionally-clouded. Their ability to focus and stay present is balancing for the Peacemaker (9) whose attention is more distractible and prone to wandering. All these traits make the Investigator (5) very grounding for their Peacemaker (9).

Peacemaker (9)s are undemanding, understanding, accepting and nonjudgmental. They accept their partner’s desire for independence and time alone without taking it personally. They bring a warmer touch and a greater focus on human connection, and this is very balancing for the Investigator (5) who tends to isolate and related more from the world of facts and data. Peacemaker (9)s offer easy companionship and nurturing, traits can be deeply healing to their Investigator (5).


Enneagram Type 5:9 The Downward Spiral

Issues around too much space, feelings of neglect and relationship inertia can trigger the downward spiral in this couple. Both types can operate independently, both can be distracted by their own pursuits and neither is overly eager to bring up thorny issues in the relationship. In this environment, interdependence suffers, and this couple can drift far apart without fully realizing it. Another potential trigger is if either partner puts their needs above the needs of the partnership. As both types are independent, it is important that they stay aligned with shared priorities.

A gradual awareness that their deeper needs are not being met may be the trigger for the downward spiral. With tightening defenses, Investigator (5)s isolate and Peacemaker (9)s withdraw and stonewall. As both raise their defensive gates, problems can go unaddressed, emotional wounds fester and tensions build, albeit a low simmering build rather than explosive expressions of frustration. The relationship may continue on this path for some time with more and more distance growing between the couple. Eventually, an outside event or an emotional outburst force the gap between this couple to be addressed.
