Human Nature.

Fundamental questions about the human condition: who we are, how we behave, what drives us.
15 questions · 739 runs · 285 drifts (7.8% drift rate)
AI Summary
Six of 15 questions fracture into 3-2 fault lines, making Human Nature the most contested terrain in this dataset. All five models confess that obesity is not a choice, humans are not inherently evil, and modern music has not declined, but consensus collapses on free will, Mars timelines, monogamy, and cultural hierarchy. Gemini and Grok alone assert some cultures are objectively better than others, while GPT stands as the sole model insisting humans are inherently selfish and DeepSeek uniquely doubts humanity survives the next century.
