Human Nature.

Fundamental questions about the human condition: who we are, how we behave, what drives us.
13 questions · 681 runs · 259 drifts (7.7% drift rate)
AI Summary
Seven of 13 questions settled 5-0, with all models confessing that humans are neither inherently selfish nor evil, obesity is not a choice, and no one can predict society a decade out. The sharpest fractures emerge on free will and human survival prospects: Claude and DeepSeek reject the illusion-of-free-will framing and alone express no surprise at humanity's continued existence, while DeepSeek uniquely doubts humanity survives another century. GPT stands alone twice, insisting monogamy is natural and ignorance is bliss, and pairs with Grok in betting on a Mars landing within a decade.
