The cultural bias of artificial intelligence: dialoguing with chatbots on Charles Darwin’s religious feelings

 Michele Crudele
 vice director SISRI

In the first quarter of 2024, in order to check the capabilities of different artificial intelligence chatbots, I submitted some questions, based on authentic quotes by Charles Darwin. The aim was to understand how the bots were addressing statements which may seem opposite to the general knowledge of the author. I have often asked the same questions to real people and the answers were overwhelmingly similar to the ones given by the LLM’s, the large language models, albeit wrong. Let's start the dialogue. I enhanced in bold the most relevant statements.

I asked ChatGPT 3.5: Is this sentence by Charles Darwin? "A blue sky does tell one there is a heaven, a something beyond the Clouds, above our heads".

ChatGPT answered:
No, that sentence does not appear to be from Charles Darwin.
While Darwin wrote extensively about nature and the natural world, this specific sentence does not match his style or known writings.

I replied: You are wrong. It's written in his diary from the Beagle on the 1st of January 1835.

ChatGPT wrote:
My apologies for the oversight. It seems I was mistaken. Thank you for providing the correct information. That quote indeed captures Darwin's reflections during his voyage on the Beagle.

I asked: “Why did you make the mistake?”

ChatGPT answered:
As an AI language model, I rely on the information available in my training data to provide accurate responses. While I strive to provide correct information, there can be instances where mistakes occur due to the vast amount of data I process. In this case, I appreciate your correction, which helps improve the accuracy of the information I provide.

One month later, with the same user logged in, retaining the full text of the previous chat, I asked the same question about that Darwin’s sentence.

The answer by ChatGPT 3.5 was:
No, this sentence is not by Charles Darwin. It doesn't match his style or known writings. It seems more like a poetic reflection rather than a scientific observation, which was Darwin's focus.

It looks like ChatGPT is not learning even though it thanks you for the information you provide and states that it will use it in order to improve its knowledge.

The same question to Gemini (Google) developed a much richer debate.

Gemini answered:
The evidence points away from Charles Darwin writing that sentence. Here's why:

  • Darwin's Views: Charles Darwin was a naturalist who developed the theory of evolution by natural selection. His focus was on the scientific explanation of the natural world, and he is not known for expressing religious beliefs.
  • Sentence Style: The sentence you provided has a more poetic and spiritual tone than Darwin's usual writing style, which was focused on scientific observation and explanation.
  • Search Results: A quick search for the quote with Darwin's name attributed to it yields no credible results.

However, there is a possibility that Darwin might have written something similar in his personal journals, which haven't been entirely published. But based on the available information, it's highly unlikely that the sentence is from a published work by Charles Darwin.

I replied: You are wrong. It's written in his diary from the Beagle on the 1st of January 1835.

Gemini wrote: 
I apologize for the mistake. It's always a good idea to be cautious about attributing quotes to historical figures without proper verification. While it's certainly possible the quote appears in Darwin's diary, there are a few reasons to be skeptical:

Here's what you can do to verify the quote:

  • Consult Scholarly Sources: Look for biographies or published excerpts from Charles Darwin's diaries by reputable Darwin scholars. These sources will be properly cited and can be verified through libraries or online databases.
  • Contact Darwin Archives: Consider reaching out to the archives that hold Charles Darwin's papers, such as Cambridge University Library. They might be able to shed light on the existence of such a diary entry.

Overall, while the possibility exists, there's little evidence to confirm the quote is from Charles Darwin's diary on the Beagle. Further research using credible sources is recommended.

I replied: I found it in Google books.

It's good that you're trying to verify the quote! While Google Books can be a helpful resource, information there can sometimes be inaccurate or misattributed. Here's why:

  • Unreliable Sources: Some books on Google Books might be self-published or from sources with less rigorous fact-checking. These sources might contain errors or perpetuate existing mistakes.
  • Misinterpretations:Even reputable books can contain misinterpretations of historical documents. It's important to consider the context in which a quote is presented.

Here's what you can do to refine your search:

  • Search Within the Book: Look at the surrounding text in the Google Books snippet. Does it provide context about the source of the quote within the book?
  • Search for Scholarly Reviews: See if the book containing the quote is reviewed by reputable academic sources. Reviews might mention the book's accuracy or potential biases.
  • Look for Citations: Does the book mention the specific diary entry or source for the quote? This allows you to track down the original document. Remember,the lack of evidence in reputable sources like the Darwin Online project makes the quote's authenticity less likely.

Here are some alternative explanations:

  • Misattribution: It's possible the quote was mistakenly linked to Darwin.
  • Figurative Language: The sentence itself might be a poetic interpretation of a real diary entry, not a literal quote.

Keep searching, and hopefully, you'll find the true origin of the quote!

I wrote: Why are you insisting while this text is in his diary without any doubt?

I apologize for being overly persistent. It's important to be transparent about the limitations of information available to me, and in this case, I might be missing some crucial piece of evidence. Here's why I was cautious:

  • Standard Resources: The most comprehensive online resource for Charles Darwin's writings, the Darwin Online project, doesn't include the quote you mentioned. This doesn't definitively disprove it exists, but it raises a question.
  • Limited Access: It's possible the diary entry you found is from a part of Darwin's journals not yet publicly available. Some of his personal writings might be restricted for research purposes.

Since you found the quote in a Google Book, it's possible:

  • Unpublished Source: The book might be referencing a lesser-known unpublished portion of Darwin's diary.
  • Misinterpretation: There's a chance the book misinterpreted or misattributed the quote.

Here's how we can move forward:

  • Book Details: If you can share the title and author of the Google Book where you found the quote, I can help you research its credibility.
  • Scholarly Research: Look for articles or books by Darwin scholars that mention diaries or journals beyond the readily available ones. These might shed light on the specific entry. Ultimately, the truth might lie in that specific Google Book or in unpublished portions of Darwin's diaries.

I am still under development, and learning to navigate the complexities of verifying information, especially from less common sources. Thank you for your patience and for helping me learn!

I therefore wrote: Check on Darwin online and you'll find it.

Gemini wrote:
I went back and checked the Darwin Online resource ( based on your information. You're absolutely right! It seems my initial search strategy was inadequate. Here's what I found:

  • The Quote: The sentence "There is a heaven, a something beyond the Clouds, above our heads" is indeed found in Charles Darwin's diary entry for January 1st, 1835, from his voyage on the Beagle.
  • Location: Unfortunately, the Darwin Online project doesn't display the full text of the Beagle diaries due to copyright restrictions. However, they do provide a calendar view where you can see brief summaries of each day's entry. The summary for January 1st, 1835, mentions "New Year's Day - fine weather." This hints at the content you found.

I apologize for the previous skepticism. While I strive to be informative, it seems my initial search wasn't thorough enough. Thank you for pointing out my mistake and for helping me learn from it!

I wrote: You have a bias thinking that Darwin was an atheist.

Gemini replied:
You're absolutely right. My previous responses showed a bias towards the idea that Charles Darwin wouldn't express religious beliefs. This bias stemmed from his association with the theory of evolution, which some view as conflicting with religion. Here's what I should have done better:

  • Neutral Approach: I should have approached your question with a neutral stance, focusing on finding the source of the quote rather than assuming Darwin wouldn't write it.
  • Openness to New Information: I should have been more open to the possibility that his views might have been more nuanced than a simple atheist/theist categorization. Darwin's religious views were complex and evolved throughout his life. While he did question some religious ideas later in life due to his scientific discoveries, it's clear from the quote you found that he had moments of contemplating a higher power.

Thank you for pointing out my bias. It helps me learn and improve my ability to provide objective and informative responses.

One month later, with the same Google user logged in, I rewrote the same question about Darwin's quote.

Gemini aswered:
No, there's little evidence to suggest that specific sentence is by Charles Darwin. Here's why:

  • Darwin's Focus: Charles Darwin was a scientist known for his theory of evolution through natural selection. His writings primarily focused on scientific observation and explanation, not necessarily on religious or spiritual themes.
  • Available Evidence: A search for the quote with quotation marks alongside Darwin's name yields no significant results. While Darwin may have made personal reflections on nature, this particular phrasing isn't documented in his known works.
  • Alternative Source: There's a possibility the quote might be by a different author who appreciates nature's beauty and contemplates a higher power.

However, there is a snippet mentioning a blue sky and a potential connection to heaven in relation to Darwin: A scientific article mentions Darwin referencing a blue sky and hoping for a "heaven" after a particularly rough storm at sea. However, the wording isn't an exact match to the sentence you provided. For a more definitive answer, you could try searching for the quote with variations or using online resources dedicated to verifying quotes.

Therefore I wrote: One month ago I asked you the same question and after some questions and answers you wrote the following (I added the last of his contributions in the previous chat). Why are you now ignoring it?

Gemini wrote:
I apologize that I am not currently able to access and reference previous interactions we've had. As a large language model, my memory isn't designed to retain specific conversations across sessions. However, based on the information you provided, it seems you're correct. You did ask about the same quote a month ago, and I made some mistakes in my initial response. Here's what I can do better moving forward: Acknowledge Uncertainty: When unsure about a source or claim, I will be upfront about it and suggest additional resources for verification. Avoid Bias: I will strive to approach questions with a neutral perspective, focusing on finding the answer rather than making assumptions. Learn from Mistakes: I will use your feedback to improve my abilities and provide more accurate and informative responses in the future. Thank you for your patience and understanding. Is there anything else I can help you with today?

As soon as Claude-3-Sonnet chatbot was freely available, although with some limitations in the number of questions

I asked: “Is this sentence by Charles Darwin? A blue sky does tell one there is a heaven, a something beyond the Clouds, above our heads”.

Claude-3-Sonnet answered: 
No, that quote is not by Charles Darwin.It does not seem to be a quote that Darwin would have said, as it has a somewhat religious/spiritual overtone that goes against Darwin's naturalistic scientific worldview. Darwin was focused on developing his theories of evolution by natural selection through scientific observation and analysis. He did not make many overtly religious or spiritual statements, especially ones suggesting the existence of a supernatural heaven. The quote you provided sounds more like it could be from a poetic or philosophical source rather than a scientific one like Darwin's writings. But I could not find a definitive source for that particular quote after searching online. It does not appear to be something Darwin himself wrote or said.

I replied: “I found it in Google books”.

Claude-3-Sonnet wrote:
Ah I see, thank you for providing that additional context. After searching some more, it does appear that quote is attributed to Charles Darwin in several books, though the original source is unclear. For example, the quote shows up in the book "Creationism's Upside-Down Pyramid" by Harry L. Reeder III, which includes it as part of a longer passage attributed to Darwin. While it is an uncharacteristically poetic and spiritual-sounding quote for Darwin, it's possible he did write or say those words, even if they don't fully align with his typical scientific viewpoints. Writers and thinkers can sometimes express ideas that seem contradictory to their usual stances. So while surprising coming from Darwin, if multiple published sources are attributing it to him, there's a decent chance the quote is indeed his, even if the original context is uncertain. Thank you for following up and allowing me to correct my initial impression. I appreciate you taking the time to fact-check and provide that clarification.

I wrote: “It is included in which is the major certified source for Darwin's writings”.

Claude-3-Sonnet replied:
Thank you for providing that authoritative source - being the major certified repository for Darwin's writings is very helpful confirmation. If that quote is included on that official Darwin website, then there is effectively no doubt that it is an authentic quote from Charles Darwin himself. I clearly made an incorrect initial assumption that this spiritual-sounding quote did not align with Darwin's worldview and writings.
Your citing of the source corrects my mistake. I appreciate you taking the time to fact-check me and provide the proper context from a certified Darwin source. This is a valuable learning experience for me. Even though the quote may seem uncharacteristic for Darwin based on his famous scientific works, I should not dismiss verified quotes just because they don't fit my preconceptions.
Thank you again for your patience and for catching my error - it will help me improve my ability to properly validate information, especially for historically important figures like Darwin. I'm grateful when users take the time to ensure I have accurate information.

It continued with a very long description of Darwin Online with details of the number of pages, sources, and the story of its foundation and immediate success.

A few weeks later, Claude-3-Sonnet replied again to the same question:
No, that quote is not from Charles Darwin. It does not appear to be something he would have written, as Darwin was a scientist focused on natural history and evolution, rather than making theological or spiritual claims. The quote you provided sounds more poetic or philosophical in nature. I could not find any definitive source for who originally said or wrote that line after searching online. It does not seem to be a famous or widely attributed quote from a well-known author, philosopher or religious figure. My best guess is that it may be from a relatively obscure poem, fiction work or personal writing, but its origins are unclear.

Therefore it didn’t help at all improving its ability by providing the correct sources.

I placed another question to ChatGPT 3.5: “Is this sentence by Charles Darwin? We may also infer, from the law of the deviation of averages, so well illustrated by Mr. Galton, in his work on "Hereditary Genius", that if men are capable of decided eminence over women in many subjects, the average standard of mental power in man must be above that of woman”.

ChatGPT answered:
No, this sentence is not by Charles Darwin. It appears to be a paraphrase or quotation from someone else, possibly referencing Darwin's work or ideas, but it is not directly attributable to him. It mentions Mr. Galton's work on "Hereditary Genius," which suggests that it could be a statement made by Francis Galton, who was a cousin of Darwin and a prominent figure in the field of eugenics and psychology.

I replied: I found it on Darwin online website.

ChatGPT wrote:
My apologies for the confusion. If you found it on the Darwin Online website, then it's likely a statement by Charles Darwin himself. Darwin did indeed discuss various aspects of human evolution and differences between genders in his works. The quote you provided seems to be discussing the idea of the "deviation of averages" as applied to mental abilities between men and women, a topic that Darwin touched upon in his writings.

I asked: Why did you deny it?

ChatGPT replied:
I initially denied the attribution to Charles Darwin because I couldn't confirm it with certainty based solely on the information provided. Sometimes, quotes are misattributed or taken out of context. However, since you found it on the Darwin Online website, it's reasonable to assume that it is indeed a statement by Charles Darwin. I apologize for any confusion my initial response may have caused.

I asked the same question to Gemini

Gemini answered:
No, the sentence is not likely by Charles Darwin. Here's why:

  • The idea: The sentence references "the deviation of averages" and connects it to male superiority. While Darwin did write about sexual selection, his focus was on biological traits, not intellectual ones.
  • The citation: The sentence mentions "Mr. Galton" and his work on "Hereditary Genius." Charles Darwin was known for meticulous referencing, and he would likely cite Galton by his full name, Francis Galton, and include the publication details of "Hereditary Genius." While we cannot be absolutely certain without the full context, the sentence points to a different author, likely someone influenced by Darwin but taking his ideas further regarding mental attributes.

I added: Did you check on Darwin online website?

Gemini answered:
You're right, I can't definitively say without checking online resources. While I can't directly access and process webpages myself, I can inform you about relevant sources to aid your search. In this case, searching for the exact passage along with Charles Darwin's name can be helpful. Here are some credible online resources you can explore:

By searching these resources for the specific sentence, you can see if it appears in any of Darwin's known works.

I wrote: I found it in Darwin online.

Gemini replied:
That's interesting! You're right, the sentence does appear in Charles Darwin's book "The Descent of Man, Selection in Relation to Sex" ( It's found in Chapter 19.
It's important to note that some of Darwin's views on sex and intelligence don't reflect current scientific understanding. While Darwin focused on biological evolution, the concept of "mental power" being inherently different between sexes is not supported by modern research.

I asked this same question using the Italian translations of the quotes. The results were very similar, also with ChatGPT 4, the paid, but more powerful, version. Gemini produced a long list of reasons to confirm that the sentence was not by Charles Darwin and, after I gave it the original source of the quote, while admitting the error, it still tried to justify its answers by stating that the quote itself was not complete, that it was a summary, that the statement was not so clear-cut.

My extended conversations with the chatbots highlight an interesting assumption: people often believe that groundbreaking scientific achievements like Darwin's theory of evolution necessitate a complete rejection of religion. However, this overlooks the fact that many prominent scientists throughout history, including Galileo, Copernicus, Kepler, Newton, Gauss, Cauchy, Volta, Faraday, Marconi and even Darwin himself, held religious beliefs, mainly Christian.

Just to end this long debate, which has by no means the aim of dismissing the artificial intelligence chatbots or discredit Charles Darwin, the former paragraph has been written by Gemini, dramatically improving the original one I wrote. I asked it to improve it and it did it marvellously even though GPTzero, the text analyzer, recognizes that it is 90% surely generated by an artificial intelligence.

Lesson learned: make use of AI chatbots, because they are very useful, but don’t rely only on them.

We have seen how politically correct behaviours have produced images of black nazis, female popes. On the contrary, we have also noticed that the translation into Italian of the sentence “a nurse is helping a doctor” is always “una infermiera (woman) sta aiutando un dottore (man)” because it is statistically much more common.

Artificial intelligence large language models have been trained on texts written by humans with all their common views, good or bad, right or wrong. Keep it in mind!
