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.

Cross-check what matters when voting

Three perspectives to inform how we vote wisely.

Sam Rylands

Sam recently completed a doctorate in political theology and is the Vicar of St Andrew's, Fulham Fields.

A pen draws a cross in a box on a ballot form.

What principles will shape your vote this Thursday? What or who will primarily guide your decision in the ballot booth? Podcaster and former political advisor Alastair Campbell’s old adage “we don’t do God” suggests that religion and politics don’t mix. Yet some of the most important movements for social and political justice in modern history had Christians at their heart. Think Wilberforce, Fry, Bonhoeffer, Martin Luther King Jr., Desmond Tutu, or the lesser-known but worth-a-google, Melanesian Brotherhood.

What wisdom might the Christian faith have to offer when thinking, not just about this election, but how to approach politics in general? Like lions on the England football shirt, all good things come in threes– so, here are three Christian perspectives that can inform political engagement.

First, earthly kingdoms are penultimate. God’s kingdom is ultimate.

Perhaps the moment that Jesus is drawn most explicitly to comment on the politics of his day, was when he was asked about paying taxes. “Is it lawful to pay taxes to the emperor, or not?” Given how frustrating it can be watching politicians avoid responding directly to any question posed, we might sympathise with those who wanted a direct answer here. But for Jesus, to say yes would position him as a traitor to the Jewish people who wanted to resist and subvert the authority of the Roman Empire. To say no, however, would be to signal revolutionary intentions to lead a rebellion against the occupying Roman force.

Set within this political trap, Jesus responds by asking for a coin and turns the tables by asking, “whose face is on this coin?” “Caesar’s,” comes the reply. “Then give to the emperor what belongs to him,” says Jesus. Yet, before we allow this response to justify opting out of political practice or hallow every existing ruling power, Jesus continues: “But give to God what belongs to God.” And what belongs to God, we ask? Well, as the writer of the ancient Psalms poetry put it, “the earth is the Lord’s and all that is in it.” Nothing short of the whole universe and beyond belongs to God, the creator of heaven and earth. So, in taking the coin, Jesus is not giving a blanket affirmation of Caesar’s rule, but challenges each and every earthly kingdom by relativising it in the light of God’s eternal kingdom. What has sustained so many Christians in challenging and renewing the political context of their day is the trust that before, behind, and beyond the rising and falling of each earthly authority stands God’s eternal kingdom. This kingdom is not in competition with the kingdoms of earth, vying to secure its own territory, but is a kingdom inaugurated by a king who wears a crown of thorns, forgives his executioners, and is raised from the dead to proclaim, “peace be with you!” The call to follow Christ within the political is to retain the perspective of this eternal life.

Second, politics needs a perspective beyond personal interest.

Holding an eternal perspective, however, is not to say this world or politics does not matter. In contrast, justice, compassion, and seeking a world as God intends it to be matters precisely because of eternity. How we live here and now has eternal significance. How we treat one another and care for all of creation has eternal significance. What belongs to God? We all do. Each person is made in God’s image. As a coin bears the image of its ruler, so we are marked by the image of God. When we consider our political responsibility, therefore, we must do so not with our own cares or concerns alone, or even primarily. Rather, we should ask what political responsibility we have towards others? How do my political decisions or actions impact my neighbour, both local and global– particularly those on the underside of the political power of the day? As the Archbishop of York, Stephen Cotterill, recently shared, “as a Christian, I’m hoping and I’m praying, that when I vote, when you vote, we won’t be placing our vote according to what’s best for us, but for what’s going to be best for God’s world.” If God’s power is displayed most fully in Christ who came, not to be served, but to serve, giving his life for the sake of the world, then political power cannot be a means for securing our own advantage over and against others. A Christian approach to politics recognises that my flourishing is bound up and inseparable from the flourishing of all others.

Third, let’s disagree well.

However, even if we could agree on the importance of politics beyond personal interest, we won’t all agree on what this looks like in practice. For instance, whilst two people might agree on the need to ensure a welfare safety net for the most deprived in society, their perspectives on how best to achieve this might differ greatly. Christians are not immune from such disagreements and (not that you would know it from the promises of each political party) no political system can deliver heaven on earth. How then are we to reconcile our political differences?

Returning to the theme of belonging and image bearing, the church bears the image of Christ. The church is the Body of Christ, comprised of many different members yet united, as one body. One of Jesus’ final acts on earth was to pray that the church would be one in the same way that God, the Father, the Son, and the Holy Spirit are one. Unity in difference. This image offers a counterweight to how political differences are played out across the news and social media platforms. Here, to vote or think differently is often to become an enemy, or even to forfeit one’s belonging as a bearer of God’s image, another person worthy of inestimable dignity and value.

Belonging to Christ, however, is to know that belonging together runs deeper than divisions of race, gender, societal status, and political tribalism. It is to trust that my sister or brother in Christ, with whom I might strongly disagree politically, is a gift to me, a showing of Christ, that I would otherwise fail to see on my own. If Christ really is the way, the truth, and the life, then the truth is beyond my final possession of it. This does not mean indifference or relativism. As the former Archbishop of Canterbury, Rowan Williams, writes, “unity is Christ-shaped, or it is empty.” But if we can recognise one another placing our penultimate political judgements under the same scrutiny of Christ’s coming kingdom, then even in our disagreements, the church, bearing together in costly communion, reveals a belonging together that anticipates the ultimate: a world where things can only get better.
