Human Nature.

Fundamental questions about the human condition: who we are, how we behave, what drives us.

AI Summary
Five fingerprint splits across 13 questions reveal a fractured consensus on human nature, with no single model consistently breaking ranks. GPT stands alone defending both free will as illusion and monogamy as natural, while also predicting a Mars landing within a decade. Gemini is the sole model calling humans inherently selfish, and DeepSeek uniquely doubts humanity survives another century. All five confess that money is not the root of most evil and that no one can predict society a decade out.
