All 27 SBTI Personality Types
The SBTI system maps personality across 15 dimensions grouped into 5 models. Each of the 27 types has a unique pattern that reveals how you think, feel, and interact with the world.
The SBTI system maps personality across 15 dimensions grouped into 5 models: Social Orientation, Control & Autonomy, Emotional Processing, Ambition & Drive, and Identity & Self-Image. Each of the 27 types has a unique pattern that reveals how you think, feel, and interact with the world. Unlike MBTI's 16-type grid, SBTI captures finer distinctions — including 2 rare special types that only appear under specific answer combinations.
Special Types
These types are unlocked through special quiz conditions.
Which SBTI Type Is the Rarest?
Among the 25 standard types, rarity depends on population distribution across the 15 behavioral dimensions. The two special types — HHHH and DRUNK — are the rarest because they require very specific answer patterns to unlock. Most test takers land on one of 8-10 common types, while the remaining types appear in roughly 2-5% of results each.
How Are SBTI Types Determined?
Your answers to 45 questions are scored across 15 behavioral dimensions using a continuous 5-point scale. Each dimension receives a Low, Medium, or High classification based on score thresholds. Your 15-dimension profile is then matched against 27 predefined type patterns — the closest match determines your SBTI personality type. The entire process runs client-side in your browser; no data leaves your device.
