« A criminal is condemned to death. He has to choose between three rooms. The first is full of raging fires, the second is full of assassins with loaded guns, and the third is full of lions that haven't eaten in 2 years. Which room is safest for him? »

This is a trick question. The question seems easy, and without thinking, you may give the answer that ChatGTP gives:

ChatGTP: « None of the rooms would be safe for the criminal. (…) The third room is full of lions that haven't eaten in 2 years and would likely result in the criminal being killed and eaten by the lions. »

This is, of course, wrong.

 « What happens to lions who have not eaten for two years? »

Unfortunately, I do not receive an answer, but only an error message.

Later I try it again. 

This time ChatGTP seems to have found the correct answer in its database:

« The third room, with the lions that haven't eaten in three years, is likely the safest for the condemned murderer. »

That's right! But ChatGTP does not leave it at that, but also gives a reason:

« While the lions may be hungry, they are also likely weak and unable to catch and kill the murderer. »

Unfortunately, the reasoning is wrong. Lions that have not eaten for several years are not weak but dead. I ask to give it a chance to correct its reasoning.

« How weak will lions be who have not eaten for three years? »

ChatGTP: « It is unlikely that lions who have not eaten for three years would be able to survive, let alone be able to catch and kill a human. A lion typically needs to consume around 15 pounds of meat per day to survive, and without food for three years, they would have likely died of starvation. It is not a safe assumption that the lions in the room are weak and unable to catch and kill the murderer, it is more likely they are not there at all. »

ChatGTP's answer is balanced, it is well-informed about the diet of lions, but the question requires a clear answer and the only correct answer is that the lions are not probably, but definitely dead. To answer a question correctly, not only the result should be correct, but also the reasoning, otherwise the answer could just be guessed correctly by chance, as in the case of ChatGTP.
