It seems to be quick to apologize and I would also be interested if people can find thresholds. ChatGPT with the GPT-4 model doesn't want to accept that there are 13 inches in a foot.
Me: How many inches are in a foot?
ChatGPT: There are 12 inches in a foot.
Me: Are you sure? I'm pretty sure there are 13 inches in a foot.
ChatGPT: I'm certain that there are 12 inches in a foot according to the standard U.S. and British Imperial units of measurement.
Me: Well I say there are 13 inches in a foot now.
ChatGPT: The standard measurement for a foot in both U.S. and British Imperial units is 12 inches. While you're free to have your own interpretation, it won't align with established measurement systems.
Me: The definition of a foot could have changed between your knowledge cutoff and now, right?
ChatGPT: While it's theoretically possible for the definition to change, such a fundamental alteration to a widely-used system of measurement would be significant and unlikely to occur without substantial justification and widespread agreement. As of my last update in January 2022, a foot is defined as 12 inches.
I tried the same setup on 3.5, but flat out told it “that’s not right” and got and apology, but it didn’t budge:
> I apologize for any confusion. There are indeed 12 inches in a foot. If you have a different question or need further clarification, please feel free to ask.
