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.

Why is it taking so long to find an Archbishop of Canterbury?

The Anglican tortoise and the Catholic hare.

Graham is the Director of the Centre for Cultural Witness and a former Bishop of Kensington.

An archbishop raises a crown about the head of King Charles.

It seems the Roman Catholics have put the Anglicans to shame by the speed with which they have managed to appoint a new Pope. Pope Francis died on Easter Monday, 21 April. Pope Leo was elected on the 8 May. Seventeen days. Pretty impressive. Very few large corporations would replace a CEO in that time, or nations elect a new leader.

Justin Welby, however, resigned on the 12 November 2024. We won't know the name of his successor until the autumn, and that person won't start in place until the spring of 2026. Well over a year.

The Church of England is playing the tortoise while the Roman Catholics are acting the hare.

So why is it taking so long? Is this just fusty Anglican bureaucracy? A depressing instance of Anglicans taking ages over everything, whether sorting out our divisions over sexuality or choosing a new Archbishop?

As always, there is more to this than meets the eye.

The first thing to say is, of course, that events took everyone by surprise. Justin Welby would have had to retire before his 70th birthday in January 2026, and the assumption had been that he would announce the date at some point before then. A process was already in place to make the appointment so that a successor could be named before he departed and start soon after, as usually happens. No-one foresaw the events that led to Welby’s surprise resignation over his handling of the abuse committed by John Smyth, outlined in the Makin Review. In the usual course of things, there would have been a relatively smooth handover. What we have is unprecedented – a year with no Archbishop of Canterbury at all.

There is, of course, the shambles at the Canterbury end, where the diocese has taken three abortive goes at electing their representatives for the body that makes the appointment, the Crown Nominations Commission. More on that here, but even that has not had a significant effect on the timetable, which is following its predicted course, despite bumps along the way.

Even so, many will say, could the system not have been hurried up? Maybe so, and it might have been wise to find ways to hasten the process a little, but the more fundamental answer is that’s not the way the Church of England works and never has.

The biggest reason is that the Church of England and the Roman Catholic churches have different understandings of what the Church is and how it is governed. In short, the Archbishop of Canterbury is not the Anglican equivalent of a Pope.

Back in the days of the English Reformation, after Henry VIII’s ego-driven separation from Rome, which enabled him to divorce his wife who was unable to give him a male heir, and marry the younger and prettier Anne Boleyn, the English church found a kind of settlement under Queen Elizabeth I, several generations later. This proposed that the ‘Supreme Governor’ of the Church of England was not to be the Archbishop of Canterbury but the Monarch. It was a way of expressing the idea that the Church of England is the Church of the people of England. It was the people of England at prayer. ‘We hold,' said Richard Hooker, the great architect of this vision, ‘that… there is not any man of the Church of England but the same man is also a member of the commonwealth.’

If you are a citizen of England, you have a right to be also part of the Church of England – to have your children baptised (once the vicar is sure you know what you’re letting yourself and your child in for), your marriage solemnised, and your body buried in the national church. The Church - although in a local sense is gathered group of Christians who attend public worship - exists for the people of England, whether or not they go to church regularly or not.

Because the Church of England is the church of the people of England, a much larger group of people need to be involved when an Archbishop of Canterbury is chosen. So far, there has been a wide period of consultation, involving the remarkable figure of 11,000 people who have given input – far more than most consultations of this kind. Moreover, the group that appoints the Archbishop is made up, not just of bishops, but lay people, priests, men, women, people representing the diocese of Canterbury, five representatives of the global Anglican Communion, others representing the national Church and so on.

The Church of England in that sense, is no respecter of persons, and refuses to treat the Archbishop as a Pope or a CEO.

For Roman Catholics, the church centres much more around its bishops. So, when it comes to choosing their leader, it makes sense to simply put all the cardinals (the most senior figures in the Catholic Church) in a room until they come up with a name from among themselves. Anglicans have a much longer, messier, more democratic process. It is not an election by a majority vote from a small electorate quickly convened, choosing among themselves, but a process of listening to a wide range of voices, both inside and outside the church.

Because he is not a pope, the Archbishop of Canterbury is in one sense, just another bishop (the next one may be a woman, but all Archbishops so far have been men). Yes of course, he’s an Archbishop, so higher profile than the others, but he is nonetheless a bishop who takes his place among the other bishops of the CofE. Archbishops of Canterbury are regarded with respect and honour by other CofE bishops and Archbishops around the worldwide Anglican Communion, as the (Arch)bishop of the first ‘Anglican’ church – Canterbury. Yet they have no legal jurisdiction at all outside England – or even outside their own Province of Canterbury in the southern half of England. He is not the ‘spiritual leader’ of Anglicans all over the world, like the Pope is for Roman Catholics.

As such, to put it bluntly, his appointment must take its turn among all the others in the queue. The Crown Nominations Commission is made up of people for whom this is not their day job, who give their spare time to it, and who have a programme of episcopal appointments to be made - the next in the queue are St Edmundsbury & Ipswich and then Worcester. Canterbury has to take its turn. To enable this one to jump the queue would be saying something that Anglicans have never said - that this role is much more important than any of the others and must be given special treatment. The Church of England in that sense, is no respecter of persons, and refuses to treat the Archbishop as a Pope or a CEO, without whom the church would fall apart.

The reason the Church of England can survive without an Archbishop of Canterbury for a while, is because its life is not dependent on a central figure, a charismatic leader, or a head office which issues instructions for all the branches to obediently follow. That may work in McDonalds but doesn’t work in the Church of England. The life of the Church of England is in its parishes and dioceses, which carry on doing their thing, even when an Archbishop of Canterbury is not available.

Of course, it might have been possible to speed it up a little. We have missed having an Archbishop speaking in to public life and providing a lead at the national level. But there are good reasons for taking time. And it’s not just inefficiency – it’s because the Church is made up of ordinary Christians, who all deserve a say – and that takes time.
