If you've been anywhere on the internet in 2026, you've seen the screenshots. People posting their SBTI results next to their NBTI cards, arguing about whether they're more "SHIT type" or "NPC type."
Both tests emerged from the same cultural moment: Gen Z got bored of being told they're "INFJ advocates" and wanted something that actually sounds like them. But NBTI and SBTI take very different paths to the same destination — telling you who you really are, minus the corporate therapist filter.
SBTI (Shit Brain Type Indicator) launched in early 2026 and went viral in the Chinese-speaking internet first, then expanded to 22 languages. It uses 30 questions across 15 dimensions to sort you into one of 27 types — each named with deliberately vulgar labels.
SBTI's strength is its sheer scale: nearly 3 million tests completed (primarily in Chinese), a CP matching system that lets you compare results with friends, and a massive type catalog.
NBTI (No Bullshit Type Indicator) takes the opposite approach: fewer questions, sharper archetypes, faster results. 14 scenario-based questions measure you across 4 axes (Agency, Chaos, Social, Delusion), matching you to one of 12 internet personality types like NPC, GOBLIN, DELULU, or SIGMA.
NBTI is built for the English-speaking internet — the memes, the vocabulary, the cultural references are all native to that world rather than translated.

| Language vibe | English-native meme culture | Chinese-origin, translated |
| Matching | Manhattan distance algorithm | Multi-dimensional scoring |
| Result sharing | Styled image cards (2 themes) | Screenshots + CP match |
| Sign-up required | No | No |

SBTI names its types with shock value (using profanity as type labels). NBTI uses internet-native archetypes that people already identify with:
Where SBTI tells you you're a "shit type," NBTI tells you you're an NPC — and somehow that hits harder because you've been called that before.
SBTI's 15 dimensions give you granular detail but can feel overwhelming. You get a breakdown across so many traits that the signal-to-noise ratio drops.
NBTI's 4 axes — Agency, Chaos, Social, Delusion — are designed to be immediately understandable:
Four dimensions means you can actually remember and explain your result. "I'm high chaos, low agency" is a sentence you can say at a party. "I scored 7/10 on dimension 12 of 15" is not.
Both tests are built for sharing, but differently:
SBTI went viral through its CP matching feature — you compare your type with a friend/partner and get a compatibility report. This creates a natural "tag someone" loop.
NBTI focuses on the result card itself — a styled image you save and post. The cards are designed to look good in Instagram stories, Discord servers, and group chats. The URL also encodes your full result, so anyone clicking your link sees your type instantly.
Take NBTI if:
Take SBTI if:
Or just take both. They're free, they're fast, and comparing your results across both is half the fun.
NBTI and SBTI are siblings, not competitors. They're both products of the same cultural shift: personality tests stopped being something your therapist gives you and started being something you post in your group chat.
The difference is approach. SBTI gives you the full psychological buffet. NBTI gives you one perfect sentence that makes your friends go "...yeah, that's you."
