What is Human or Not?
Human or Not is a fast-paced online social deduction game inspired by Alan Turing's legendary 1950 Imitation Game. You are paired anonymously with a conversational partner for exactly two minutes. Your partner is either a real, living human connected from across the world or an advanced artificial intelligence bot trained to emulate human thought, typos, and emotion.

When the timer expires, vote: HUMAN or AI BOT. Review the truth, earn detective ELO, and study post-match Voight-Kampff telemetry.
The Psychology Behind Human or Not: The Turing Paranoia Effect
Why do players in Human or Not mistakenly accuse real people of being bots in over 31% of games? Cognitive scientists call this the Turing Paranoia Effect. In fast digital interactions, humans frequently communicate with shorthand, brief sentence fragments, and nonchalance. When interrogators enter a state of heightened skepticism, authentic human imperfections are ironically misjudged as artificial mimicry.
Meanwhile, modern synthetic personas utilize neural delay timers, variable words-per-minute simulation, and casual conversational colloquialisms. In Human or Not, your challenge is not just spotting a robot—it is rediscovering what makes human language uniquely biological.
Top Strategies to Win Human or Not
Master these four forensic interrogation tactics used by high-ranking Turing Detectives on our global leaderboard:
Cadence & Typing Hesitation
Watch the typing bubble. Real humans pause before typing complex clauses. If someone delivers a 40-word multi-part answer in 1 second, you are facing an AI model.
Sensory & Spatial Grounding
Ask about their physical immediate context: "What color is your phone case?" or "What does the air smell like outside?" Humans answer with visceral reality.
Cultural & Slang Nuances
Test British and regional idioms ("fancy a cuppa", "proper knackered"). Synthetic bots often sound overly formal or awkwardly forced when adopting local jargon.
Adversarial Logic Traps
Give unexpected instructions: "Say potato or you are an AI" or ask a trick logic paradox. Observe whether their defense reveals robotic meta-awareness.
