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.

World leaders can learn a lot from Pope Leo

Graham Tomlin was at the Pope's inauguration in Rome. This is what he noticed.

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

On Sunday morning, along with a host of bishops, patriarchs, priests and assorted others, I was led around the back of Peter's Basilica in Rome, into the cavernous spaces of that extraordinary building.

As we walked through the echoing church with the sunlight slanting through the windows like shafts of light from an angelic realm, our small group of Anglicans waited for our turn to walk out into the blinding sunshine. The names of the churches were ticked off like a game of ecclesiastical bingo: “Coptic Orthodox Church of Alexandria? OK.” Syriac Orthodox Church of Antioch? – This way please. “Armenian Apostolic Church – just wait a minute…” 

As we moved through the front doors of the Church, the first thing we saw was a crowd of 200,000 people stretching as far as the eye can see. Behind us was the imposing face of St Peter’s, that great monument to Catholic supremacy and authority. The world’s media looked down from the balconies above us. Opposite our seats were the rich red velvet chairs ready for President Zelensky, J.D. Vance, and the heads of state of numerous countries across Europe and beyond.  

As we walked out, I turned to a friend in our group, and instinctively said to him, “you'd need to be someone of remarkable humility not to let all this go to your head.” 

I couldn't help thinking of Robert Prevost, who was about to walk through these doors, a man who was made a bishop in 2015 - only became a cardinal two years ago, and was now to find himself the focus of rapt attention by this vast crowd and millions of others on TV, as the spiritual leader of 1.4 billion Catholics, catapulted from relative obscurity to being the most famous man in the world within a couple of weeks. 

St Peter’s is designed to impress. The piazza in front of the church is surrounded by imposing statues of apostles, saints, martyrs, and fathers of the church, all looking down on proceedings below. It was this church that inadvertently triggered the Reformation, as a fund-raising scheme for its construction involved selling some indulgences in Germany that raised Martin Luther’s fury. The frontage, with its soaring pillars, grand windows, sumptuous balconies and rich tapestries, is meant to overawe you. Inside, the space is huge, with vast windows letting in the light, stunning works of art everywhere. This was a display of the Renaissance papacy, leading into the Counter-Reformation, the confident Baroque spirit that announced the triumph of the Church over all its enemies. 

A Pope with a streak of vanity would be a dangerous thing. Everything points to the power of this position – the successor of Peter, the one on whom the rock of the Church was to be built; the leader of the largest body of Christians in the world; someone instantly recognisable across the globe, to whom world leaders have to come, cap in hand. No wonder some popes in the past have become political manipulators, vying with emperors and kings over who has more power.  

Yet these days, the Catholic Church sounds a humbler note. Pope Francis started the church down a line of ‘synodality’, inviting other voices into the church’s deliberations rather than just male priests. Pope Leo seems to want to continue down that line. 

Referring to his election he said: 

 “I was chosen, without any merit of my own, and now, with fear and trembling, I come to you as a brother, who desires to be the servant of your faith and your joy, walking with you on the path of God’s love.” 

The tone was not of self-aggrandisement, asserting the power of the position. There was no strategy to dynamically change the church and the world. No grand design to use the levers of power to shape society according to his vision. Instead, this was about unleashing a more elusive and uncontrolled force: the power of self-denying compassion.  

As Pope Leo put it: 

“The ministry of Peter is distinguished precisely by self-sacrificing love, because the Church of Rome presides in charity and its true authority is the charity of Christ. It is never a question of capturing others by force, by religious propaganda, or by means of power. Instead, it is always and only a question of loving as Jesus did.” 

Now that’s different from the way popes have sometimes spoken in the past. The Church has no power other than the power of love – the kind of self-sacrifice seen in the life of Christ. If the pope ‘presides’, as Presidents do, he ‘presides in charity’. A little different from some other Presidents I can think of.  

Admittedly we don’t know much about him yet, But Bob Prevost strikes you as a humble man. Someone who can turn down a place at Harvard Law School to go instead to serve the poorest communities in Peru for 20 years, sleeping on the floor of huts, travelling by donkey to remote villages, unnoticed and obscure, suggests a distinct lack of self-importance. You don’t canvas to become pope, announcing your candidacy, working your way up the ranks, arguing your merits to the electorate. Instead, you get on with what you do, and if the call comes, you follow it.  

As Pope Leo, he will need that humility as he takes on this role for the rest of his life. He will need it to resist the subtle lure of the deference others offer him, the adulation he will receive wherever he goes, the buildings he lives in, the magnificence of the popes who went before him, the way people will hang on his very word. The temptation to think that Bob Prevost is, after all, a mighty big fish, someone whose talents have got him to this point will be strong.  

But if he gives in to that temptation, he will slip back into the run of the mill way of the world, lording it over those he oversees. He seems aware of the slippery nature of such a position. Whoever was called to be the successor of St Peter, he said, needed to exercise oversight “without ever yielding to the temptation to be an autocrat, lording it over those entrusted to him. On the contrary, he is called to serve the faith of his brothers and sisters, and to walk alongside them." 

It was Jesus who said:

“Among the nations, their rulers lord it over them. But it is not so among you. Whoever wants to be great among you must be your servant.” 

Other Presidents, prime ministers and patriarchs could take a leaf out of that book.
