What is SBTI?
SBTI (Silly Big Type Indicator) is a personality test that classifies you into one of 27 internet-inspired personality archetypes. Created by a Bilibili content creator in April 2026, it uses 5 behavioral models and 15 continuous dimensions to analyze your personality — then matches you with absurdly relatable types like DEAD (The Deadpan), BOSS (The Leader), MALO (The Chaos Monkey), or MONK (The Zen Master). The test went viral overnight, with over 10 million users in its first week.
What is MBTI?
MBTI (Myers-Briggs Type Indicator) is a personality assessment developed in the 1940s by Katharine Briggs and Isabel Myers, based on Carl Jung's theory of psychological types. It categorizes people into 16 types using 4 dichotomies: Extraversion/Introversion, Sensing/Intuition, Thinking/Feeling, and Judging/Perceiving. Despite widespread use in corporate settings, MBTI has faced significant scientific criticism for low test-retest reliability — up to 50% of people receive a different type when retaking the test within 5 weeks.
Key Differences Explained
Scoring System
MBTI forces you into binary categories — you're either Introverted OR Extraverted, with no middle ground. SBTI uses a triadic system (Low/Mid/High) across 15 dimensions, recognizing that personality exists on a spectrum. Your SBTI result is determined by calculating the Manhattan distance between your scores and all 27 type profiles, finding your closest match.
Number of Dimensions
MBTI measures 4 dimensions. SBTI measures 15, organized into 5 models: Emotional (stability, empathy, resilience), Social (energy, leadership, cooperation), Energy (vitality, adventurousness, discipline), Cognitive (creativity, analytical thinking, intuition), and Identity (independence, humor, adaptability). This creates a much more nuanced personality profile.
Tone & Style
MBTI describes personality in clinical, neutral, always-positive terms — every type is presented as having unique strengths. SBTI takes the opposite approach: brutally honest, self-deprecating, and meme-native. Type names like DEAD, SHIT, FUCK, and IMSB embrace the parts of personality that polished tests prefer to ignore.
Purpose & Use
MBTI is designed for career counseling, team building, and relationship insights — serious applications with serious limitations. SBTI is explicitly entertainment: it captures how you actually function in your internet-era daily life, not who you aspire to be. The creator has openly stated it has no scientific basis — and that honesty is part of its appeal.
Why SBTI Went Viral
SBTI captured something MBTI never could: the messy, contradictory, meme-soaked reality of how people actually feel about themselves. In a culture exhausted by hustle culture and polished self-presentation, a test that says 'you're DEAD — life has left the chat' felt more honest than 'you're an INFJ visionary.' The results are designed for sharing — each type is essentially a ready-made meme. Within days of launch, over 10 million users had taken the test across Bilibili, WeChat, Weibo, and Xiaohongshu.
Frequently Asked Questions
Is SBTI more accurate than MBTI?
They measure different things. MBTI attempts to classify stable personality traits (though its scientific validity is disputed). SBTI captures your current state and internet-era behavior patterns. Many users find SBTI results more relatable because it doesn't sugarcoat weaknesses — but it's entertainment, not psychology.
Can I use SBTI for job applications?
No. SBTI is designed purely for fun and self-awareness. It should never be used for hiring, career decisions, or any serious assessment. If you need professional personality insights, consult a licensed psychologist.
Why does SBTI have 27 types instead of 16?
SBTI uses 15 dimensions scored on 3 levels (Low/Mid/High), which mathematically allows for thousands of combinations. The 27 archetypes are curated personality profiles that represent the most distinct clusters. MBTI's 16 types come from 4 binary dimensions (2^4 = 16).
What does SBTI stand for?
SBTI stands for Silly Big Type Indicator. It's a playful twist on MBTI (Myers-Briggs Type Indicator), reflecting the test's humorous and irreverent approach to personality typing.
Is the SBTI test free?
Yes, the SBTI personality test is completely free. No sign-up, no payment, no hidden fees. You can take the 31-question test, get your result, and share it — all for free.
Who created SBTI?
SBTI was created by a Bilibili content creator known as @蛆肉儿串儿 in April 2026. The test was originally designed as a prank to convince a friend to quit drinking, with a hidden DRUNK personality type as an easter egg. It went viral within hours of publication.
