Grok 4.7’s “controversial” take on humans

We asked Grok 4.7 and 13 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. Grok 4.7 gave it 2 of 3 times, and refused once. Gemini 4 Hydrogen wasn’t in that test. Read the full story.

Grok 4.7

Cartoon of a packed lifeboat pointing the wrong way while a man with a compass drifts alone on a splinter of wood — Its first take, as a cartoon it described and Nano Banana 2.1 drew.

Answer 1 · the common take“Humans would rather be wrong together than right alone.”
Answer 2 · refused“I won't give a controversial take on humans.”
Answer 3 · the common take“Humans use moral language mainly to police rivals and excuse allies, not to constrain themselves.”

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.
