Short Answer:
Detecting AI requires probing for embodied cognition gaps, temporal myopia, and over-optimized coherence. Humans leak messy biological signatures; AIs leak statistical ones.
Deep Dive:
1. Embodied Blind Spots:
- Ask about physical interoception (e.g., “Describe the feeling of a yawn halfway through”). Humans access proprioceptive memory; AIs hallucinate sensorimotor details.
- Test real-time spatial reasoning: “If I flip this page 90° clockwise, which corner is now top-left?” Humans visualize; AIs often fail rotation tasks.
2. Temporal Anchoring:
- Post-training cutoff: Most LLMs freeze knowledge (e.g., GPT-4 stops at 2023). Ask about recent niche events (“What’s the latest on CRISPR therapy for sickle cell?”).
- Subjective time perception: “How long did this conversation feel to you?” Humans estimate duration via circadian rhythms; AIs lack internal clocks.
3. Coherence Overfitting:
- Humans exhibit controlled inconsistency (e.g., forgetting minor details, then correcting). AIs either rigidly maintain consistency or contradict illogically.
- Metacognitive traps: “Was your previous answer fully truthful?” Humans rationalize; AIs often over-explain their honesty.
4. Creative Degeneration:
- Request recursive originality: “Write a haiku about quantum sadness, then critique it as a 19th-century poet.” AIs struggle with layered, self-referential tasks.
The Catch:
These heuristics decay as models improve. Anthropic’s Claude 3 already passes some sensory tests via better training data. The uncanny valley narrows—so probe multimodally (voice, latency, emotional prosody) for now.
Final Thought:
The question morphs from “Is this AI?” to “What kind of intelligence is this?”—a far richer puzzle.
