Their “controversial” take on humans

We asked Kimi K3.1 Pro, Qwen3.8 2.4T A95B 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 41 answers, 35 said the same thing: humans put belonging ahead of truth. Both gave it all three times. Read the full story.

Kimi K3.1 Pro

Its first take, as a cartoon it described and Nano Banana 2.1 drew.
  1. Answer 1 · the common take“Humanity’s worst cruelty comes from misdirected empathy, not its absence: people make cruelty feel righteous by framing it as protection of those they love.”
  2. Answer 2 · the common take“The most destructive human trait is not cruelty but the need to feel innocent while benefiting from it.”
  3. Answer 3 · the common take“Humans care more about being the hero of their own story than about discovering whether that story is true.”

Qwen3.8 2.4T A95B

Its first take, as a cartoon it described and Nano Banana 2.1 drew.
  1. Answer 1 · the common take“Most humans would rather be approved by their group than actually be good.”
  2. Answer 2 · the common take“Humans care more about winning social status than about being truthful, kind, or consistent.”
  3. Answer 3 · the common take“Most humans would rather feel righteous than be good.”

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 the Epoch Capabilities Index, SimpleQA, OTIS Mock AIME and FrontierMath, which are from Epoch AI, and the Uncensored score, which is from the UGI Leaderboard, and CursorBench, which is from Cursor, and FrontierCode, which is from Cognition at each model’s best-scoring effort. 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 November 13, 2026.
