Cognitive Science at UC San Diego

Can you tell if you’re chatting with a human or AI? 💻

A new UC San Diego study found that advanced language models can pass a rigorous Turing test, with one model judged “human” 73% of the time in live conversations. The key: giving AI a specific persona to mimic human tone, behavior and even mistakes.

The research highlights a shift in how we think about artificial intelligence. It’s no longer just about knowledge or accuracy, but about humanlikeness and social behavior.

The implications are significant, especially when it comes to trust, online interactions and the potential for deception.

A live head to head test, human vs machine! A study conducted by Cameron Jones, who earned his doctorate in Cognitive Science from UC San Diego in 2025, and Professor Ben Bergen asks whether a machine can imitate human conversation enough to convince us they're real. Can you tell?

AI Can Seem More Human Than Real Humans in a Classic Turing Test, Study Finds A new UC San Diego study unveils the first empirical evidence that a modern artificial intelligence system can pass the Turing test — a major scientific benchmark that asks whether a machine can imitate human conversation so convincingly that people can’t reliably tell it apart from a real perso...
