If you have seen the SBTI personality test on social media, you have probably asked the same question many other people ask: what exactly is the difference between SBTI and MBTI? This article gives you a full comparison across purpose, question design, result style, scientific grounding, and real-world use so you can understand how SBTI relates to MBTI.
What is SBTI?
SBTI stands for Silly Big Personality Test. It is a joke-heavy parody personality test inspired by MBTI. It was created by Bilibili creator @蛆肉儿串儿 in April 2026, originally as a way to persuade a friend to stop drinking. Unexpectedly, it went viral almost overnight and quickly reached tens of millions of views.
The core idea behind the SBTI personality test is simple: it has no scientific basis and is built for self-mockery and entertainment. Unlike formal personality assessments, SBTI is designed to give you a result that feels weirdly accurate, then makes you want to screenshot it and send it to your friends.

What is MBTI?
MBTI stands for Myers-Briggs Type Indicator, one of the most widely known personality classification frameworks in the world. It is based on Jungian psychological type theory and divides people into 16 personality types such as INTJ and ENFP through four preference dimensions:
- Extraversion (E) vs Introversion (I)
- Sensing (S) vs Intuition (N)
- Thinking (T) vs Feeling (F)
- Judging (J) vs Perceiving (P)
MBTI is widely used in workplaces, education, and social settings, although its scientific validity remains debated in academic circles.

Comparing the Test Experience
The SBTI experience
Taking the SBTI personality test feels a bit like talking to a brutally honest friend. The questions are strange, the answer choices are ridiculous, and yet the result often lands with an oddly uncomfortable sense of accuracy.
- The question order changes each time, and hidden questions may appear
- The results page includes a custom personality card and a detailed, funny interpretation
- It is easy to screenshot and share immediately on social media
- The whole test only takes a few minutes, often less than a coffee break
The MBTI experience
Taking MBTI feels much closer to a formal personality assessment:
- The questions are standardized and more serious in tone
- It usually takes longer and expects more careful reflection
- The result gives you a four-letter type and a more detailed analysis
- It focuses more on self-understanding and developmental guidance
SBTI Types vs MBTI Types
MBTI divides personality into 16 types, each represented by four letters, such as INTJ "Architect" or ENFP "Campaigner". These types are defined around cognitive functions and behavioral preferences.
SBTI personality types come from a completely different creative universe. For example:
- IMSB - Less a personality type than a full mental condition
- DRUNK - The origin point of the entire SBTI project, created to talk a friend out of drinking
- BOSS - Sounds impressive, but may just mean you interfere too much
- ZZZZ - A suspiciously accurate description of some people's everyday life
- SEXY - The personality type that lives mostly in its own imagination
Every SBTI type comes with its own illustration and sharp-tongued write-up. You can browse them all on the SBTI types page.
Is SBTI a Replacement for MBTI?
Strictly speaking, SBTI is not a replacement for MBTI. Their goals are fundamentally different. MBTI tries to help you understand your personality preferences, while the SBTI personality test is mainly trying to make you laugh.
That said, many people do treat SBTI as a more relaxed alternative in practice:
- If MBTI feels too serious, SBTI gives you the same "take a test, get a result, share it" loop in a much lighter tone
- If you have already taken MBTI, SBTI offers a completely different and more playful way to "re-meet yourself"
- If you just want a fun personality quiz to take with friends, SBTI is built exactly for that

Final Takeaway
SBTI and MBTI may look similar on the surface because both involve answering questions and getting a type, but they are fundamentally different in purpose and tone. MBTI is a serious personality framework. SBTI is a comedic parody inspired by that format. The two are not in conflict. You can absolutely take MBTI today for self-reflection and then try the SBTI personality test tomorrow just to laugh at yourself a little.
