Why 15 Dimensions? A More Nuanced Personality Portrait Than MBTI
Unlike traditional personality tests with 4-dimensional models, SBTI introduces 15 tightly coupled cognitive dimensions to form a comprehensive personality profile. If MBTI draws you a quick sketch, SBTI takes a high-definition panoramic photo of your personality.
SBTI's 15 dimensions are grouped into 5 core models:
Self Model
Emotion Model
Attitude Model
Action Drive Model
Social Model
Compared to MBTI's 4 dimensions and 16 types, SBTI's 15 dimensions capture far more personality details. For example, MBTI only tells you "you're extroverted," while SBTI breaks it down into your Social Initiative (So1), Interpersonal Boundaries (So2), and Expression & Authenticity (So3) β you might love initiating social interactions but keep strong boundaries, or be passive socially yet extremely authentic.
Self Model (Self Model): S1 Β· S2 Β· S3
The Self Model focuses on how you evaluate yourself, whether you have a clear understanding of who you are, and whether your core values remain stable. This is the foundational layer of SBTI assessment β how you treat yourself determines how you treat the world.
S1 Self-esteem & Confidence
Self-esteem & ConfidenceAssesses whether your self-evaluation is stable and your psychological resilience when facing external feedback.
You're harder on yourself than anyone else β even a compliment makes you fact-check it first. Prone to self-doubt and need external validation to confirm your self-worth.
Your confidence level fluctuates with the weather β soaring when things go well, shrinking back when facing headwinds. Sometimes you feel great about yourself, other times you spiral into self-doubt.
You have a solid sense of who you are and aren't easily shaken by random comments from strangers. Possess stable self-worth that external opinions can't easily undermine.
S2 Self-clarity

L/M/H Scoring System: From Raw Scores to Personality Vectors
Scoring Process
- Answer Scoring: Each question corresponds to one dimension, with option scores ranging from 1-3 points
- Dimension Summation: Each dimension consists of 2 questions, with total scores ranging from 2-6 points
- Level Conversion:
- 2-3 points β L (Low)
- 4 points β M (Medium)
- 5-6 points β H (High)
- Vector Generation: The levels of 15 dimensions form a 15-character vector, e.g.,
HHH-HMH-MHH-HHH-MHM - Personality Matching: Using Manhattan Distance algorithm to match against 27 personality archetypes
Manhattan Distance Algorithm: Compares the user's 15-dimensional vector with each personality's 15-dimensional template, calculating the sum of absolute values of differences for each dimension. The smaller the distance, the higher the match. For example, if a user has H(3) in S1 and the CTRL type also has H(3) in S1, the dimension difference is 0; if the user has L(1) and CTRL has H(3), the difference is 2.
How to Interpret Your 15-Dimension Report
After receiving your SBTI results, don't just focus on the 4-letter personality code β pay more attention to the distribution pattern of the 15 dimensions. Here are some interpretation tips:
1. Look for Extreme Values
Which dimensions are H and which are L? These extreme values often reveal your most prominent personality traits. For example, a Self Model with H-H-H (high scores in S1-S2-S3) typically corresponds to CTRL or BOSS types, showing strong self-control.
2. Analyze Inter-Model Relationships
Are there contradictions between the five models? For example, high Social Initiative (So1-H) combined with strong Interpersonal Boundaries (So2-H) means you initiate social interactions actively but maintain distance β possibly a "warm yet distant" type.
3. Check Match Accuracy
Your results page will show "Precise Match X/15 Dimensions". If the match rate exceeds 80%, your personality traits are highly typical; if below 60%, the system may assign you to the HHHH (Happy-Go-Lucky) fallback type.
4. Observe Dynamically
SBTI encourages multiple tests. You may get different dimension distributions at different times and in different states. Observing these changes is more valuable than a single test result.
