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.

Alice Roberts’ new book is the Da Vinci Code without the pretence of fiction

Tomes like Domination are part of the problem of public discourse about Christianity, not the solution

Alice Roberts would like you to read her book, thank you very much.

She recently took to X to bemoan the “epidemic” of people offering thoughts about her latest offering, without actually having read it. The person who prompted Roberts’ exasperation was a senior lecturer in Biblical Studies and the latest in a long of professional scholars of Christianity who had greeted the release of the book with little more than a weary eyeroll. 

The reason so many people felt as though they didn’t need to read it is because it is utterly predictable. Even a cursory glance at any of the marketing that has accompanied the publication of Domination: The Fall of the Roman Empire and the Rise of Christianity really does tell you all you need to know. It really is the book you think it is. 

You already know what this book is going to argue. Just like you already know how this review is going to go. I’m a theology lecturer who works for the Church of England; Roberts is an outspoken atheist and former president of Humanists UK. Of course I’m going to disagree with this book. It’s hardly the sort of plot twist you endure an M. Night Shyamalan film for.

But, for the avoidance of doubt, let me be clear: I don’t dislike Alice Roberts’ book because I’m a Christian and she’s not. I dislike Roberts’ book simply because it’s not very good.  

Roberts seeks to “lift the veil on secrets that have been hidden in plain sight.” (Always be wary of someone who claims to have noticed something no-one else has for the last 2,000 years). These ‘secrets’, she suggests, are that “the main reasons [Christianity spread so successfully] were not to be found in the pages of the Bible, but in a powerful alliance born of complex – and very human – incentives”.  

For Roberts, the central, overriding reason why Christianity flourished was simply economic and political power. In her own words, “the worldly aspects of the Church are undeniable. Wealth and power go hand-in-hand, and the Church had both in abundance.” It’s never clear who actually is thought to be denying this, except a vague group described as “apologist historians (including some who claim not to be Christian, but seem to be suffering from some kind of Stockholm syndrome) and theologians”.  

And this power-grab has been the aim since the earliest moments of the Church’s existence. The Apostle Paul is painted in cartoonishly Machiavellian tones: “As a Pharisee, a member of an established Jewish sect, Saul would have been a small fish in a big pond. The switch to this new breakaway sect [Christianity] would make him a prominent figure in a small but rapidly growing movement”. 

A few pages later – in a section that made me laugh so hard I had to put the book down for a few minutes to collect myself – Roberts offers a genuinely baffling reading of one of Paul’s early letters, to a group of Christians in the city of Corinth. In the letter, Paul speaks about divisions in the Church, with Christians claiming to ‘follow’ different leaders (such as Paul and Apollos). Roberts writes that “there’s a hint that Paul may have viewed Apollos as competitor” and continues: 

“When Paul wrote his first letter to ‘the Corinthians’ … he exhorted them to see themselves as united, whether they were following him, [or] Apollos … Paul, however disgruntled he might have been about the competition represented by other, potentially more eloquent, preachers, had decided it was best to team up. Still, he couldn’t quite resist suggesting his superiority – or at least, his priority – to Apollos: ‘I have planted, Apollos watered.’”. 

See?! SEE?! It’s all about power!! 

Well, that last bit is a quote from Paul’s first letter to the Corinthians, the third chapter and its sixth verse. Now, what Roberts doesn’t tell the reader is that she has left off the rest of the verse, and the verse that follows. “I planted, Apollos watered, but God gave the growth. So neither the one who plants nor the one who waters is anything, but only God who gives the growth.”  

But this is very different indeed to the impression Roberts gives us. Paul is quite clearly not claiming any sense of superiority over Apollos. No, he claims they’re both nothing, and that God alone deserves credit for anything good done by either of them. Not that you would know this from Roberts’ butchering of biblical texts.  

(As a slightly technical aside, the bit Roberts does quote should read ‘I planted,’ not ‘I have planted’. This sounds trivial but in the Greek text, Paul writes in a different tense than the one Roberts translates it as. This made me wonder what translation of the Bible was using or whether it was her own. However, there are no notes in the book. At all. And no mention of Bible translation that I could find. If we’re engaging in character assassinations of folk no longer alive to defend themselves, we might think that attention to the precise wording of their thought might be important. Apparently not). 

And there’s the rub. Roberts leave precisely zero room for earnest belief in God. Not her belief in God, obviously, but that the people whose words she has hacked and placed before us might earnestly think that their actions seek the betterment of those around them because of their belief in God. No. It’s all about power. I’ve highlighted her treatment of Paul in particular (again, because I found it genuinely hilarious), but time would fail me if I tried to recount all the ways that other figures in Church history are treated similarly. 

Roberts’ has complained about Frank Cottrell-Boyce (whom, she notes, is “a Catholic” as though this is in any way relevant to whether he’s right) for describing Domination as ‘cynical’. But how else could we possibly describe this? Yes, it is – of course – completely reasonable to highlight the social, cultural, political, and economic forces at work in and around the development of Christianity (is anyone actually suggesting otherwise?). And yes, of course some people have used Christianity for personal gain (seriously: is anyone actually suggesting otherwise?). 

But Roberts goes far beyond both points. Instead, she is simply stripping back the theological content of Christianity and claiming to have found “secrets that have been hidden in plain sight” having done so. But of course human motivation is all that is left once you strip belief in God out of religion, because what else could there be? Roberts’ prose may be captivating, but her argument is deeply immature and reductive. It’s like a toddler who’s just read Michel Foucault’s work on social power for the first time: an impressive toddler, to be sure, but a toddler nonetheless.  

Roberts does acknowledge that “people are complex, human societies are complex”, but this is little more than lip-service to nuance. None of this complexity is found in the actual argument of her book. It reminds me of someone saying, “no offence, but …” before going on to say something deeply offensive. A fleeting caveat doesn’t redeem a simplistic argument. 

In this respect, it’s quite telling that the front-cover endorsement comes from Stephen Fry who describes it as “a historical thriller of the highest quality.” In one respect, he’s not wrong. It reads like a thriller and – questions of content aside – might easily grip read readers with its compelling prose and rhetorical flourishes. But that’s because this is The Da Vinci Code without the pretence of fiction. A compellingly told conspiracy theory dressed up in just enough spliced-together reality to feign plausibility.  

Public discourse about religion and faith is too often conducted with a sneering cynicism that seeks to ride roughshod over the sincerely held beliefs of actual people who would actually describe themselves as religious. Books like Domination are part of the problem, not the solution.  

Maybe this is why I find Domination bordering on offensive. Not because of its content. (If I got upset every time someone ascribed bad motivations to the Church I’d never leave the house.) No, I find it borderline offensive because of its sheer existence. Whether you like it or not, religion has been and is an irrevocably vital part of who we are and where we’ve come from. Religious belief deserves at the very least to be understood, even if not agreed with. And so, when I finished Domination, I was left wondering: is that is? Is this the highest standard of discourse society can really be offered about religion? Dan Brown in an academic gown? Heaven help us, if so. 

The covers may be similar, and the titles may sound alike, but this is not Tom Holland’s Dominion. Where Holland’s work remains one of the most insightful and thoughtful accessible books about the development of Christianity and modern society, Roberts’ cynicism (for that is what it is) is both tiresome and tiring. (Moreover, that Holland’s book is not even mentioned once speaks volumes about Roberts’ work. That Roberts insists she has read it only makes that absence more baffling). 

The Church deserves more rigorous champions of atheism to scrutinise its belief; society needs a better class of conversation about religion and its role in our history. I fear Alice Roberts is not the former; Domination is certainly not the latter.
