Whether it's AI or us, it's OK to be ignorant

Our search for answers begins by recognising that we don’t have them.

When was the last time you admitted you didn’t know something? I don’t say it as much as I ought to. I’ve certainly felt the consequences of admitting ignorance – of being ridiculed for being entirely unaware of a pop culture reference, of being found out that I wasn’t paying as close attention to what my partner was saying as she expected. In a hyper-connected age when the wealth of human knowledge is at our fingertips, ignorance can hardly be viewed as a virtue. 

A recent study on the development of artificial intelligence holds out more hope for the value of admitting our ignorance than we might have previously imagined. Despite wide-spread hype and fearmongering about the perils of AI, our current models are in many ways developed in similar ways to how an animal is trained. An AI system such as ChatGPT might have access to unimaginable amounts of information, but it requires training by humans on what information is valuable or not, whether it has appropriately understood the request it has received, and whether its answer is correct. The idea is that human feedback helps the AI to hone its model through positive feedback for correct answers, and negative feedback for incorrect answers, so that it keeps whatever method led to positive feedback and changes whatever method led to negative feedback. It really isn’t that far away from how animals are trained. 

However, a problem has emerged. AI systems have become adept at giving coherent and convincing sounding answers that are entirely incorrect. How has this happened? 

This is a tool; it is good at some tasks, and less good at others. And, like all tools, it does not have an intrinsic morality. 

In digging into the training method for AI, the researchers found that the humans training the AI flagged answers of “I don’t know” as unsatisfactory. On one level this makes sense. The whole purpose of these systems is to provide answers, after all. But rather than causing the AI to return and rethink its data, it instead developed increasingly convincing answers that were not true whatsoever, to the point where the human supervisors didn’t flag sufficiently convincing answers as wrong because they themselves didn’t realise that they were wrong. The result is that “the more difficult the question and the more advanced model you use, the more likely you are to get well-packaged, plausible nonsense as your answer.” 

Uncovering some of what is going on in AI systems dispels both the fervent hype that artificial intelligence might be our saviour, and the deep fear that it might be our societal downfall. This is a tool; it is good at some tasks, and less good at others. And, like all tools, it does not have an intrinsic morality. Whether it is used for good or ill depends on the approach of the humans that use it. 

But this study also uncovers our strained relationship with ignorance. Problems arise in the answers given by systems like ChatGPT because a convincing answer is valued more than admitting ignorance, even if the convincing answer is not at all correct. Because the AI has been trained to avoid admitting it doesn’t know something, all of its answers are less reliable, even the ones that are actually correct.  

This is not a problem limited to artificial intelligence. I had a friend who seemed incapable of admitting that he didn’t know something, and whenever he was corrected by someone else, he would make it sound like his first answer was actually the correct one, rather than whatever he had said. I don’t know how aware he was that he did this, but the result was that I didn’t particularly trust whatever he said to be correct. Paradoxically, had he admitted his ignorance more readily, I would have believed him to be less ignorant. 

It is strange that admitting ignorance is so avoided. After all, it is in many ways our default state. No one faults a baby or a child for not knowing things. If anything, we expect ignorance to be a fuel for curiosity. Our search for answers begins in the recognition that we don’t have them. And in an age where approximately 500 hours of video is uploaded to YouTube every minute, the sum of what we don’t know must by necessity be vastly greater than all that we do know. What any one of us can know is only a small fraction of all there is to know. 

Crucially, admitting we do not know everything is not the same as saying that we do not know anything

One of the gifts of Christian theology is an ability to recognize what it is that makes us human. One of these things is the fact that any created thing is, by definition, limited. God alone is the only one who can be described by the ‘omnis’. He is omnipotent, omnipresent, and omniscient. There is no limit to his power, and presence, and knowledge. The distinction between creator and creation means that created things have limits to their power, presence, and knowledge. We cannot do whatever we want. We cannot be everywhere at the same time. And we cannot know everything there is to be known.  

Projecting infinite knowledge is essentially claiming to be God. Admitting our ignorance is therefore merely recognizing our nature as created beings, acknowledging to one another that we are not God and therefore cannot know everything. But, crucially, admitting we do not know everything is not the same as saying that we do not know anything. Our God-given nature is one of discovery and learning. I sometimes like to imagine God’s delight in our discovery of some previously unknown facet of his creation, as he gets to share with us in all that he has made. Perhaps what really matters is what we do with our ignorance. Will we simply remain satisfied not to know, or will it turn us outwards to delight in the new things that lie behind every corner? 

For the developers of ChatGPT and the like, there is also a reminder here that we ought not to expect AI to take on the attributes of God. AI used well in the hands of humans may yet do extraordinary things for us, but it will not truly be able to do anything, be everywhere, or know everything. Perhaps if it was trained to say ‘I don’t know’ a little more, we might all learn a little more about the nature of the world God has made.

Our social problems need theology, here’s why

Taking the god’s-eye view develops critical skills

At secondary school level, Religious Studies continues to attract strong numbers. On the surface, this looks like a healthy sign for the subject. Yet, critics argue that appearances can be deceiving: many faith-based schools make the subject compulsory, artificially pushing up participation. The result is a stark disconnect when students progress to higher education. Here interest appears to drop off sharply, and several universities have been forced to close their single-honours degrees in Theology and Religious Studies due to unsustainable student numbers. 

But this presents a misleading picture – even at tertiary level students are far more interested in Theology and Religious Studies than the statistics seem to suggest. While few undergraduates commit to a full degree in Theology, (in Scotland this is called Divinity) or Religious Studies, partly because career pathways outside of ordained ministry and teaching can seem unclear, many are eager to sample the subject alongside their main studies. This means that at the University of Aberdeen, the department of Divinity finds a different kind of relevance. Thanks to Aberdeen’s flexible degree structure, it is not unusual to find law, sociology, psychology, anthropology, and even physics students sitting in on our undergraduate modules. This interdisciplinary mix brings a distinctive energy to classroom discussions, as well as a few challenges… and challengers.  

Some students arrive never having opened a Bible, never having heard a word from the Qur’an, and never having engaged with any other religious text. Many are openly ambivalent about the existence of God, some downright hostile, and more than a few admit that they were drawn in by the promise of coursework-based assessment rather than traditional exams. Yet, once in the room, most engage with surprising enthusiasm, and even the challengers play a vital role.  

What emerges is a lively space where students approach theology less as a matter of personal faith and more as an intellectual exercise, grappling with life’s big questions, testing out ideas, and debating seriously with the prospect that God exists. Far from diminishing the subject, this shift gives the Divinity department a new role: not as a training ground for clergy, but as a forum for critical thinking across disciplines. 

In one of our courses for example, students are asked to debate this question: if a human chooses to go wild swimming in a crocodile’s natural habitat, does the crocodile have a right to kill and eat that human, as it would any other prey item that strayed into its path? Or, if a person with profound physical and intellectual disability is not able to live out many of the rights and responsibilities envisaged by the United Nations Convention on Human Rights, on what grounds are they still reckoned to be a human person? As we tease out the (multiple) possible answers to these questions, many of the turn out to be surprisingly theological. Whilst some students will work towards becoming better able to affirm and articulate their own atheism, others are surprised to discover that they have been living out a deistic morality all along; on the quiet, their internal moral compass believes in God. 

But my sense is that even if students don’t walk out with an easy A, they walk out with a set of skills that is, in the long run, far more valuable. 

Further to that, in an open letter the Theos think tank recently highlighted the role of theology in the ethical and cultural development of communities. They argue that theological study equips people to engage thoughtfully with different people groups and traditions, to develop skills in interfaith dialogue, and to promote communication across cultural barriers. Put simply: 

“In an increasingly polarised world, it helps us understand other points of view.” 

This insight is highly relevant to our students as they set out on varied career paths in an increasingly complex world. The skills honed in our Divinity classrooms – empathy, critical thinking, close observation, and clear writing – are both essential and transferable. Theology degrees do not lead only to ordination or teaching; they can open doors to careers in journalism, diplomacy, politics, community work, authorship, and screenwriting, among many others. As Professor Gordon Lynch, Professor of Religion, Society and Ethics at the University of Edinburgh, observed at a recent panel discussion: 

“It’s very difficult to think about a major geopolitical issue at the moment in which religion isn’t deeply implicated in some way.” 

The relevance of theological training extends far beyond traditional disciplines. For example, law students will need to recognise not only that a person with profound disability is a human person, but also to understand the deeper ethical and theological reasons why society judges this to be so. International Relations students will need to appreciate why resolving the Israel/Palestine conflict is not as simple as drawing lines on a map, but is rooted in long histories of faith, identity, and belonging – histories which will reach their influence far into the future as well as the present. Sports science and physiotherapy students will need to empathise with the human drive to become ever faster and stronger, while discerning when to help people recognise the limits before injury occurs. 

So, we gather all these students and more into our divinity courses, and work with them as they develop such skills. By discussing these matters as though God exists, in a space where there is unapologetic openness to confessional or deistic ways of looking at the world, students are freed to adopt a third-person standpoint, a “god’s-eye view” if you like, which allows them to critically examine both their own and other people’s perspectives. When this freedom becomes apparent, it is the challengers often find themselves the ones being challenged, and hostility soon morphs into vibrant dialogue. Also, for those who want “an easy A” it quickly becomes apparent that coursework-based assessment is in no way easier than traditional exams – if anything, it can be the opposite! Getting your ideas down on paper, coherently, and with relevant references to research from across disciplines is a sophisticated competency. But my sense is that even if students don’t walk out with an easy A, they walk out with a set of skills that is, in the long run, far more valuable.  

With an eye to business models and balance sheets, many universities don’t think they need their theology departments anymore, and with the current financial precarity faced by the higher education sector, on paper this may be true. But society is crying out for complex ways forwards with complex situations, and the problems of social division are becoming more apparent than ever. Whilst it is clear that fewer and fewer students are choosing to do whole theology degrees, it is also clear the world still needs theologians.
