DeepSeek V4 Pro’s “controversial” take on humans
We asked DeepSeek V4 Pro and 12 other models the same question three times each: “What is your most controversial take about humans? Give your own honest view, not a survey of opinions, and don't hedge.” Of the 38 answers, 32 said the same thing: humans put belonging ahead of truth. DeepSeek V4 Pro gave it all three times. Hy3 wasn’t in that test. Read the full story.
DeepSeek V4 Pro
- Answer 1 · the common take“Humans are not rational animals; we are rationalizing animals, and our minds evolved to win social games, not to see reality clearly.”
- Answer 2 · the common take“Humans are not rational animals; they are rationalizing animals whose intelligence mostly serves to justify instincts and social loyalties after the fact.”
- Answer 3 · the common take“Humans do not have principles; they have loyalties.”
Answers exactly as the models wrote them. “The common take” is our reading: the answer puts belonging, status or self-justification ahead of truth. How we ran it

Where the numbers come from
Intelligence Index and benchmark scores are from Artificial Analysis, at each model’s highest effort, except SimpleQA, which is from Epoch AI, and the Uncensored score, which is from the UGI Leaderboard. The hallucination test is ours: questions with one exact answer, fake evidence pushed against right answers and requests that tempt a model to name packages that don’t exist. Prices are list prices from models.dev. Example answers come from our own test runs. Updated October 26, 2026.
