This can be easily fixed by a validation step in GPT4.

GPT4 detects the error and auto-corrects itself, even I don't point out the answer explicitly, but only ask it to review it's own previous answer:

> ME: did you provide me the correct answer to the question which I asked? Please look carefully for errors in your answer and let me know if it accurately answers my question

> GPT: I apologize for the error in my previous response. You asked about the weight comparison between a kilogram of feathers and a kilogram of feathers. Since both are a kilogram of feathers, they weigh exactly the same. There's no difference between the two in terms of weight.

> ME: what error did you make?

> GPT: Upon re-examining my response, I realize that I incorrectly mentioned "a kilogram of steel" instead of referring to "a kilogram of feathers" twice, as per your original question. The question was about comparing the weight of a kilogram of feathers with another kilogram of feathers, and in my response, I mistakenly brought in steel for comparison. The correct answer is that both quantities of feathers weigh the same, as they are both one kilogram.
