The Concept of Triads in the Enneagram (Heart, Head, and Body)

The Enneagram tends to be weirdly good at hurting your feelings with accuracy. But before you get lost in the weeds of wings and subtypes, you need to understand the engine running the whole operation: The Triads.

Think of the Triads as the operating system of your soul. There are three centers of intelligence—Head, Heart, and Body. They determine not just what you do, but why you do it, and more importantly, which specific negative emotion is currently ruining your Saturday.

Finding your Triad is the quickest way to figure out your core motivation (and your core malfunction).

The Heart Triad: The Performers

Types: 2, 3, 4

The Vibe: "Please Perceive Me (But Only From My Good Angle)"

The Core Emotion: Shame

If you belong to the Heart Triad, your entire existence is a high-stakes performance piece regarding Identity and Connection. You navigate the world through feelings—specifically, your feelings about how other people feel about you.

The engine running this bus is Shame. Now, you might not feel "ashamed" daily, but you are subconsciously terrified of being worthless, unseen, or flawed. To combat this, you construct an Image. You shapeshift. You curate. You are the person who enters a party and immediately reads the room’s emotional temperature like a Doppler radar, adjusting your personality accordingly to ensure you are loved (Type 2), admired (Type 3), or understood as unique (Type 4).

Real World Example: You post a photo on Instagram. It doesn't get enough likes in the first 12 minutes. You don't just think, "Oh, the algorithm is bad." You think, "I am embarrassing. Everyone hates me. I have no taste. I should delete my account and move to a yurt." You are looking for a mirror, and you are terrified the reflection is empty.

The Head Triad: The Strategists

Types: 5, 6, 7

The Vibe: "I Have 47 Tabs Open In My Brain Right Now"

The Core Emotion: Fear

Welcome to the Head Triad, where we are all just trying to survive the future. If you are a 5, 6, or 7, you process the world through Analysis and Security. You believe that if you can just think hard enough, gather enough information, or plan enough fun distractions, you can avoid pain.

The engine here is Fear (often rebranded as "Anxiety"). You feel fundamentally unsafe in the world, so you retreat into your mind to build a fortress. You are constantly anticipating what could go wrong and devising a strategy to outsmart it. You don't trust your gut; you trust your spreadsheet.

Real World Example: You are going on a vacation.You have read every Yelp review for every restaurant within a 5-mile radius of the hotel. You have packed a first-aid kit for ailments you do not have. You are either hoarding knowledge to feel competent (Type 5), troubleshooting worst-case scenarios (Type 6), or frantically booking activities to ensure you never have to sit alone with your thoughts (Type 7). You are trying to outrun the unknown.

The Body Triad: The Protectors

Types: 8, 9, 1

The Vibe: "I Am The Captain Now"

The Core Emotion: Anger

The Body Triad (also called the Gut Triad) brings us back down to earth. If you are an 8, 9, or 1, you don't care about your image, and you aren't overthinking the future. You are concerned with Reality, Justice, and Autonomy. You process the world instinctively. You know the truth because you feel it in your stomach.

The core emotion here is Anger. This doesn't mean you are always yelling. It means you have a visceral reaction to things being "wrong." When your boundaries are crossed or the environment feels unjust, you feel a rising heat. You want to assert your will upon the world to set it right—whether that’s by dominating the space (Type 8), numbing out to keep the peace (Type 9), or perfecting the details (Type 1).

Real World Example: You are in a meeting and someone takes credit for your work. You don't feel "sad" about this. You feel a physical sensation of rejection (Type 8 might explode; Type 1 might seethe and correct the record; Type 9 might passively-aggressively disengage). It isn't an intellectual problem; it is a boundary violation. Your body creates a wall, and you are standing behind it, demanding respect.

The Takeaway

Figuring out if you are run by Shame, Fear, or Anger isn't exactly a fun party trick, but it is the skeleton key to your psyche. Once you know your Triad, you stop thinking your reactions are "just the way things are" and realize they are a specific, predictable pattern. And once you see the pattern, you can—occasionally, perhaps, if you try very hard—choose to do something else.
