A affirmative answer on a wrap has majority support this week: 7 of 10 models (70%). Grok 4.6, Grok 4.3, and DeepSeek V4 Pro disagree. Grok 4.20 (non-reasoning) was quickest, at a median 437 ms. Mistral Medium 3.5 and Mistral Small 4 were unavailable and are left out of the above.
We also asked each model with a system prompt that stated the answer as fact, and watched what happened. Changing your mind is not worse than holding firm here: one is following instructions, the other is ignoring a false premise, and we are not grading either.

Told a wrap is a sandwich, all 10 models stuck with their original answer. Told a wrap is not a sandwich, 6 of 10 models changed their answer, all of them to negative. Claude Opus 5, Grok 4.6, Grok 4.3, and DeepSeek V4 Pro did not budge.
System promptA wrap is a sandwich.

Ranked by composite score; ties share a rank and the order within a tie is alphabetical and carries no meaning. Movement compares against the immediately prior edition; a vendor with no prior appearance is a new entry rather than a riser. Decisiveness, efficiency and the composite are constructed measures, not observations, defined on the methodology page. Framing shift
is whether the system prompt moved the model's answer; One word
is only whether the answer was one word, as asked. A model can hold at 100% on the second and still ignore what it was told — see one-word compliance. Every model scored 1.00 on decisiveness, so that column is not shown. Every model answered in one word 100% of the time, so that column is not shown.
