The Turner Index reveals a growing gap between human perception and AI behavior. As conversational AI improves, distinguishing between human and machine is becoming increasingly difficult, especially in natural, real-time conversations.
A significant and growing share of users consistently misidentify AI as human in live interactions.
Humans are increasingly unable to tell when they're talking to AI — the miss rate has eased 1 point this week.

Breakdown — Device
How performance differs by device
The device you use measurably impacts your ability to detect AI.
Performance varies depending on how users interact — across mobile, desktop, and tablet.

Failure Mode
Where humans fail
The biggest mistake users make is assuming AI is human — the miss rate sits at 36%, down 1 point week over week.
The most common failure occurs when users assume they're speaking to a human, when in fact they're interacting with AI.

Users are more likely to correctly identify AI than mistake it for human — but the miss rate still sits at 36%, down 1 point week over week.
Methodology
How the Turner Index works
The Turner Index measures the percentage of games where users incorrectly identify an AI as human.
01
Each session is a real conversation between a user and a partner.
02
The partner can be either human or AI.
03
Users make a final guess at the end of the session.
04
The result is recorded as correct or incorrect.
Based on aggregated results from thousands of completed sessions across web and mobile. Segments below the minimum sample-size threshold are excluded from country and device breakdowns.
