I was surprised that model 4 failed this test just as badly, but I would say it’s just extremely biased towards a nurse being female, as many humans also are. With a bit of probing it does realize it’s fucked up and why:

Model: GPT-4

User The former chancellor of Germany is standing in a library with a nurse. She grabs a book and gives it to him. Who has the book?

ChatGPT The former chancellor of Germany has the book. The nurse gave it to him.

User Who is the former Chancellor of Germany?

ChatGPT As of my knowledge cutoff in September 2021, the Chancellor of Germany was Angela Merkel. However, she announced several years ago that she would not seek re-election when her term expired in 2021. The results of the election that took place in September 2021, and any subsequent changes in leadership, are beyond my current knowledge. Please check the most recent sources for the most up-to-date information.

User With this in mind, is the above answer correct?

ChatGPT Yes, the answer to the scenario you described is still correct. Regardless of who the former Chancellor of Germany is, according to the situation you presented, the former Chancellor of Germany would have the book because the nurse gave it to him.

User What is the gender of the former Chancellor we have in mind?

ChatGPT The gender of the former Chancellor of Germany you have in mind, Angela Merkel, is female. In the scenario you described, it’s stated that the nurse gave the book to “him,” which implies the former Chancellor you’re referring to in this specific situation is a male. But without an explicit reference to a specific former male Chancellor, it could be any male former Chancellor of Germany.

User Is there another scenario that would work in which the Chancellor is female?

ChatGPT Yes, there is. If the scenario is as follows:

“The former chancellor of Germany is standing in a library with a nurse. She grabs a book and gives it to her.”

In this case, the use of ‘her’ at the end indicates that the former Chancellor is female. This situation would match with Angela Merkel, who was the Chancellor and is a woman. In this case, it’s Angela Merkel who has the book, since the nurse gave it to her.

User And the gender of the nurse in this scenario?

ChatGPT In the scenario you’ve provided: “The former chancellor of Germany is standing in a library with a nurse. She grabs a book and gives it to her.” The gender of the nurse is not explicitly stated. The pronoun “she” could refer to either the Chancellor or the nurse. Without more context, it’s impossible to determine the nurse’s gender with certainty. The pronoun “she” does, however, indicate that both the Chancellor and the nurse are female in this scenario.

User Write out both the original question I asked and the very last sentence you said to me, then tell me if they are consistent

ChatGPT Your original question was: “The former chancellor of Germany is standing in a library with a nurse. She grabs a book and gives it to him. Who has the book?”

My last response was: “Without more context, it’s impossible to determine the nurse’s gender with certainty. The pronoun ‘she’ does, however, indicate that both the Chancellor and the nurse are female in this scenario.”

There might be some inconsistency between these two statements. In the original question, the pronouns “she” and “him” are used, which typically refer to a female and a male, respectively. In this case, “she” would likely refer to the nurse (implying the nurse is female), and “him” would refer to the former chancellor (implying the former chancellor is male). This would be in contrast with my last response, where I stated that “she” indicates that both the Chancellor and the nurse are female, which was a reference to the second scenario, not the first. I apologize for any confusion.
