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.

The Wild God we can't coerce

Weird and increasingly encountered beyond the wilderness.

Christianity is a wild thing.

I say this, even while only half-understanding what I’m saying. It’s something that I’m learning. Or perhaps it’s more appropriate to say that it’s something that I’m unlearning. Because, admittedly, I’m far more familiar with a somewhat domesticated view of my own faith tradition. The kind that allows me to fashion fences out of my expectations; to put parameters around God’s presence and boundaries upon his behaviour. Both of which are a farce, of course - but a comforting farce, none the less.

You see, there is nothing ‘comfortable’ about a God who cannot be wholly predicted or comprehended, let alone controlled or contained. A wild God is always going to be a challenge to a culture that has enthroned comfort. We’re too easily spooked and too unused to the sensation of being cosmically baffled.

But, affronting as it may be, I am trying my best to sit in the knowledge that the God I believe in is a wild God. And I’m finding this wildness increasingly hard to ignore. Perhaps it’s all the Rowan Williams I’ve been reading, or my newfound interest in the Romantics (as in, the eighteenth and nineteenth century poets, not the 1970’s American rock band). Or maybe it has more to do with Nick Cave and the Bad Seeds’ new album, which I have been listening to relentlessly over the last week.

In this musical offering, Nick Cave introduces us to his ‘Wild God’, who I think is my God too. It’s just that ‘wild’ has never been the first adjective I reach for when describing him.

Until now, I suppose.

Let me clarify what I mean by wild, because what I’m not saying is that God is inherently chaotic, unruly, reckless or irrational. Wild Gods, as we know them from the myths and legends, act on tempestuous whims, and are more than a little havoc prone. They are perilous, largely because one can never truly know where they stand with them. That couldn’t be further from what I mean. The entire Old Testament - as complex, nuanced and masterful as it is - can be understood as a collection of ways in which the God at its centre is saying – this is who I am, this is what I desire, this is what I’m going to do, this is where you stand with me. If you were to read the Bible, it would become pretty clear pretty quickly: God is insistent that those who seek to know him will never have to second guess him. God’s wildness does not mean that we cannot know the essence of who he is or how he feels towards us. I like to think that we can endeavour to know him accurately, but never exhaustively.

Rather, what I’m trying to get my head and heart around is the knowledge that God, and therefore Christianity, cannot be wholly domesticated. Despite my best efforts, it cannot be made into an entirely comfortable and cozy thing. To make it so, one would have to dilute it, shrink it, bleed any truth out of it. In his poem - Sometimes a Wild God -Tom Hirons writes,

Oh, limitless space.
Oh, eternal mystery.
Oh, endless cycles of death and birth.
Oh, miracle of life.
Oh, the wondrous dance of it all’.

There’s an innate weirdness to the Christian worldview, a pure wildness at the heart of it. It’s brimming with mystery and mysticism. As Hirons hints, it’s bigger and more consequential than our comfort-zones would like it to be. And, what’s more, much of it is communicated through the natural world. Biblical narratives and poetry are endlessly pointing us toward the places and spaces that are outside human cultivation – the stars, the mountains, the oceans – the things that pre-date and will outlive us.

Christianity is wild in that there’s an alluring organic-ness about it. Its truth sits beyond human manipulation and coercion.

For millennia, whole lives have been given over to this truly wild and, I believe, wildly true story. Can I give you just two recent examples? Two people who have (utterly unexpectedly) adventured their way into this wild and wonderful way of seeing the world? Two people I’ve had the joy of learning from over the past year?

First up is Paul Kingsnorth.

Paul is an award-winning poet and a best-selling author of both fiction (including the Buckmaster Trilogy: Wake, Beast and Alexandria) and non-fiction (including Real England, Confessions of a Recovering Environmentalist and his ongoing Sub-Stack series: Abbey of Misrule). He is, and always has been, an advocate for treating the natural world as if it were far more than a machine to be used or a resource to be obtained. Such behaviour is, according to Paul, nothing short of sacrilegious. As well as an enchantment with what he can see and sense in the natural world, he also has a long-standing fascination with all things mystical.

Buddhism, Witchcraft – you name it, he’s tried it.

He told Justin Brierley and I the story of how he his adventures have led him to arrive at the wildest possible destination: Christianity.  

And then there’s the renowned mythologist, Dr Martin Shaw, who decided to do a 101-day wild vigil in Dartmoor. Despite not being a Christian, on the very last night, he prayed. While praying, he looked up and saw something utterly unexplainable, something ‘properly Old Testament’. And that was it – after a night of dancing, several other ‘odd’ experiences, and eighteen months of deep pondering – he was able to say, ‘I went into the forest expected to be wedded to the wild and I came out wedded to Christ’.

Thinking about it, it’s probably no accident that ‘Christianity’ began on the margins, and from there, worked its way into the cities. There was a time where the prediction of Jesus’ arrival was being yelled out into the countryside, so loudly that people were emptying the surrounding towns to come and hear more. A time when rumours of redemption were being whispered in the rural hills. A time when its chief messenger was an inexplicably weird man named John the Baptist; who shunned his prestigious priestly heritage to live in the wilds, to dress in camel skins, to eat honey and insects and insist upon the imminent coming of the long-awaited Messiah. This Messiah, by the way, who would be born where animals are kept, sleep on mountains, retreat into deserts, walk on water, speak to storms, and break people (including himself) out of stone graves.

You see what I mean, Christianity is a wild story to believe and live in accordance with.

It’s the story that drove the ‘Desert Mothers and Fathers’ of the Third Century AD to reject civilisation and all its comforts, in order to seek God in the silence and solitude of the desert. It’s the story that is still inspiring people to live in caves on Mount Athos, secluded islands just off the coast of Wales and forests in the heart of Ireland. An uncontainable message has, since its inception, been lived out in uncontainable places.

Honestly, you want weird? Christianity can darn-well give you weird.

Don’t be fooled by over-familiarity or be swayed by that pesky left-side of your brain, the part that wants to convince you that you know all that there is to know. Christianity is a story that I, myself, had forgotten was quite this wild.
