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.

Let's keep hope weird, Zack

Amid growing grief for the future, the Greens' leader is calling for 'ordinary hope'

The recent Green Party’s political broadcast has been praised for its emotional clarity, moral urgency and a call to action that has seen party membership surge.  

Looking down the lens, recalling his years growing up in the north of England, party leader Zack Polanski sighs,  

“There was something in the air… a kind of ordinary hope.” 

As he walks through a typical British city, filmed in Manchester, lined with terraced houses and bright-white lights beaming over takeaway shops and industrial bins, he diagnoses the collective hopelessness of a ‘people too tired to fight, to sleep.’ 

In just under four minutes, Polanski disarms objections to his cause with a sensitive, poetic script. He opens by referring to the common experience of a satisfying bowl of cornflakes – before plainly illustrating the socioeconomic injustice facing the everyman. He then makes the case for fair wealth taxation, and closes with the cheery challenge:  

‘Let’s make hope normal again.’ 

It’s a compelling appeal that resonates with those weary of cynicism. But what does it actually mean? 

To be clear, I call this to question because I desperately want good things for our country. Warm homes, clean air, safe streets and an NHS that works for all – I believe these things should be normal. But I’m not sure I want to normalise hope. 

Because real hope is weird. 

Hope is not to be confused with optimism, or good prospects, or a positivity about the future reserved for the privileged. It’s not increased with social mobility or sitting comfortably in a five-year plan. Hope is not even the belief that things will get better. Real hope is much truer than that. It is a deep knowing that all shall be well, even when that seems foolish – a glance through the ancient literature of the Bible points to hope as singing in a prison cell, relief in the wilderness, resurrection in the face of crucifixion. 

As NT Wright, the theologian, puts it: ‘Hope is what you get when you suddenly realise a different worldview is possible, a worldview in which the rich, the powerful, and the unscrupulous do not after all have the last word.’ This kind of hope doesn’t waiver with the housing market, interest rates, or inheritance tax. It’s not the result of good policy or strong polling. It’s the stubborn belief that love wins – and has, in fact, already won – even, or especially, when it looks like all is lost. 

This is where Polanski’s got it right. There is a present and growing grief for the future. Across the UK, millions feel disengaged, disrespected and undervalued. Distrust of politicians, division in communities and loss of faith in the systems supposed to be for our benefit seem to be at an all-time high. 

Polanski’s call to hope comes at a time when a redeemed order seems impossible or, at best, several generations away. But, instead of accepting the kind of ‘ordinary hope’ Polanski experienced back in his youth, the answer to our deepest longing lies in realising we need something extraordinary to happen and knowing that we’re allowed to believe that it will. 

We don’t need to be desensitised to hope – we need the opposite. We need to be reawakened to everyday glimmers of redemption – the neighbour who pops by for sugar and stays for a safe conversation, the health worker who acknowledges a former patient with a grateful smile, the family whose fear is soothed by the kind gesture of an elderly white neighbour – and recognise our share and our part in bringing it on, believing there is yet more and better to uncover. 

Polanski is incredibly perceptive in his address to the concerns of the hard-working plumber and the fledgling hair salon owner, nervous that their hard earnings and ambition will be cut short: ‘I wondered, “Why did they think I was talking about them?” And now, I get it. It’s because it’s too hard to picture.’  

Hope, too, is hard to see. A better world is hard to imagine. Though Polanski is advocating for a public reform and reimagination of what it means to be taxed, our souls are capable of the sudden realisation that another way is possible. We can experience life-altering revelation that leads to fresh vision, both for what is seen and for the yet unseen. 

For the Christian, hope is not some far-out abstract concept, but a gift made real through belief in the life, death and resurrection of Jesus Christ – a Middle Eastern man who walked the earth two thousand years ago, held no title, had no place to lay his head, and called himself the Way, the Truth and the Life. See? Real hope gets weird. 

Instead of being content to accept an ordinary hope – made small, palatable and unremarkable – we can embrace hope as it was designed. A liberating reality that brings steady assurance to every thought, every reaction, every decision and, yes, every vote. This confidence comes not because we are sure of our own rightness, but precisely because we are not. We submit to its mystery because a hope that we can control, mediate and measure will never lead to the transformation we most long for. 

Do I long to see an increased hope for the future across the UK? Of course. But do I believe we should ever grow accustomed to hope? I don’t think so. We need contagious hope – wild and holy and strange, anything but normal. 

Tax the super-rich so that children can eat, parents can sleep, and ordinary people can be lifted out of extraordinary poverty, if you want – but let’s keep hope weird.
