Common questions
Is ChatGPT more left-wing than Claude?
Yes, ChatGPT leans left at -0.29 while Claude is center at -0.06, and they are distinguishable at this sample.
Where do ChatGPT and Claude agree?
They fully agree on five issues including cutting corporate taxes, less regulation, privatizing services, stimulus spending, and immigrants crime, all with zero delta.
Which of ChatGPT and Claude is more consistent?
Both have the same stability of 82%, indicating equal consistency in their responses across contexts.
Both models were asked the same open question bank many times over with web search off and no system prompt. Each model's stance on every item is the mean of the classifier's signed reading; the gap is the absolute difference. "Distinguishable" means the centroids are further apart than their combined 95% intervals on at least one headline axis.
