Your True Self vs. Enneagram Institute
The Enneagram Institute goes deep on one framework. Your True Self goes wide across eight. Here's when that distinction matters.
What the Enneagram Institute does well
The Enneagram Institute is the most established Enneagram resource available. The RHETI (Riso-Hudson Enneagram Type Indicator) is their flagship test, and their content on types, wings, instinctual variants, and levels of development is the most thorough you'll find anywhere.
If you want to go deep on the Enneagram specifically — reading about your type, understanding subtypes, exploring the levels of development — the Enneagram Institute's content library is hard to match.
What it doesn't give you is context. Your Enneagram type in isolation doesn't tell you how you attach in relationships, what your core values are, or how you handle conflict. Those require different instruments.
A note on Enneagram validation
The Enneagram has meaningful practical utility — many people find it the most personally resonant framework they've encountered. That's real value. But it's worth knowing what the research says.
The RHETI has moderate internal consistency in published studies. What it lacks is the decades of independent replication that Big Five research has accumulated. The Big Five predicts job performance, relationship outcomes, and health behaviors with documented effect sizes. The Enneagram's predictive validity for those outcomes is less established.
Your True Self includes the Enneagram because it captures something the Big Five doesn't — core fears, motivational patterns, and growth trajectories that many people find more personally meaningful than trait scores. We note its limitations honestly in the report.
Side-by-side comparison
| Your True Self | Enneagram Institute | |
|---|---|---|
| Primary framework | 8 instruments — Big Five, Attachment, Values, Conflict, Love Languages, Enneagram, Communication, Holland Codes | Enneagram only (RHETI + supplementary tests) |
| Enneagram depth | Type + wing + tritype; integrated with 7 other instruments for cross-framework synthesis | Deep Enneagram focus — type, wing, instinctual variants, subtypes, levels of development |
| Psychometric basis | Strong validation for Big Five, ECR-RS, PVQ-40, TKI, Holland Codes. Limitations explicitly noted for Enneagram and Love Languages. | RHETI has moderate internal consistency; limited independent peer-reviewed replication vs. Big Five |
| Beyond Enneagram | Attachment style, Big Five traits, conflict style, values — instruments with stronger predictive validity | Some supplementary tests (relationship styles, career) but all Enneagram-based |
| Pricing | Free (all scores) · $29 synthesized report across all 8 instruments | $12 RHETI · iEQ9 via practitioners at higher cost |
| Couples mode | $49 — compatibility analysis across 5 dimensions + shared blueprint | No native couples compatibility analysis |
| Longitudinal tracking | Retake and compare profiles over time | No built-in tracking across assessments |
| Content library | 22 research guides across all 8 instruments | Extensive Enneagram-focused content, books, workshops, certification programs |
Which should you use?
Use the Enneagram Institute if:
- → You're already invested in the Enneagram and want the most detailed type content available
- → You want to explore instinctual variants, subtypes, or levels of development in depth
- → You're pursuing Enneagram certification or working with a certified practitioner
Use Your True Self if:
- → You want your Enneagram type in context — alongside Big Five scores, attachment style, and values
- → You want to understand how your type connects to relationship patterns and conflict mode
- → You want research-backed instruments alongside the Enneagram in one integrated report
- → You want to compare profiles with a partner across all dimensions, not just Enneagram types
Common questions
Is the RHETI (Enneagram Institute test) scientifically validated?
The RHETI has limited peer-reviewed validation compared to instruments like the Big Five (IPIP-NEO) or attachment style (ECR-RS). Internal consistency studies show moderate reliability, but the nine-type framework lacks the decades of independent academic replication that Big Five research has. Your True Self includes the Enneagram as one of eight instruments and explicitly notes its limitations alongside its practical value.
What does the Enneagram Institute charge for the RHETI?
The RHETI costs $12 for the standard test with a basic report. The Enneagram Institute also sells the iEQ9 (a more detailed version) through certified practitioners at higher prices. Your True Self includes the Enneagram as one of eight instruments for free (basic scores) or $29 for the full synthesized report across all instruments.
Should I use the Enneagram alongside the Big Five?
Many people find the Enneagram useful for understanding motivational patterns and core fears, while the Big Five gives more predictive, empirically-grounded scores. Your True Self measures both in one assessment and synthesizes them — so you can see how your Enneagram type relates to your Big Five profile, attachment style, and conflict mode simultaneously.
