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.

Assisted dying: in praise of being a burden

It's not a reason to end a life, it's the very possibility of our being human.
A younger hand holds a wrinkled older hand of someone in a bed.

A lot has been said already about assisted dying. In the raging bonfire of public discourse, there has been a lot of heat, but not a lot of light. But amid all the noise surrounding Parliament’s upcoming discussion around assisted dying, a recent conversation hosted by Prospect between Brenda Hale (former President of the Supreme Court) and Rowan Williams (former Archbishop of Canterbury) served as a reminder that we are, despite everything, still capable of having meaningful and fruitful discussion about even the most divisive of issues.  

The conversation is earnest and hard-won throughout; both Hale and Williams each push and probe the other for more detail, more nuance, more outworking of implications. And yet their tenor remains respectful. There is no cheap point scoring, no trite comments or easy aphorisms. These are two people working to understand the other, in full recognition of the gravity of the topic.  

One particular moment, however, was frankly spine-chilling. As the conversation progresses, Hale is asked the following: “How do you deal with the pressure questions – pressure from family or financial pressures? What safeguards can you build in?” Her response – in full, for context – is as follows: 

“Well, you can build in the safeguards that the decision must be made without undue influence, coercion, duress or fraud. But in the end, it’s a matter of evidence, isn’t it? One of the things I find most difficult is that I don’t think it’s necessarily irrational for somebody to take into account the suffering their suffering is causing to the people dear to them, or the burden that looking after them is placing upon the whole community.  

I wouldn’t call that “undue influence”, but it’s one of the questions I find most difficult about all of this. You know, obviously there’s duress, there’s financial abuse, there are all of those sorts of things that have got to be checked against, and there ought to be objective evidence of absence of that. But when it comes down to somebody thinking, “I don’t want to be a cause of others suffering,” that seems to me to be a reasonable thing for somebody to take into account.”  

The idea that my dependency or burdensomeness might factor into decisions about whether I continue to live, seems to me to be contrary to the very notion of the Christian message. Let me explain why. 

We are made to be a burden, then. To depend on others, to be burdensome to them, is to be human.

We are, whether we like it or not, now rapidly approaching Christmas. At this time of year, Christians celebrate the birth of Jesus; the divine Son of God made flesh and born of a virgin. As the divine Son of God, Jesus lived the perfect human life of joy, grace, and faithfulness; the kind of life I can only aspire to. 

Because of this, as a Christian, I look to Jesus’ perfect life of faithfulness as a model for what a truly healthy human life looks like. And I am often surprised by what I find there. For example, it turns out true human flourishing does not involve getting married, having sex, or having children; Jesus’ perfect life of flourishing featured none of these things. 

But crucially, Jesus’ perfect life often involved depending upon others; upon being a burden to those around him. As an itinerant travelling teacher, Jesus relied on the financial support of his followers to make his ministry possible. He relied on being made and given food to eat, and a roof to sleep under. He was far from self-sufficient. Rather, he gladly made himself a burden to others in service of his ministry.  

But more than this, we often overlook the radical significance of the Christian claim that, at Christmas, we celebrate God’s becoming a baby. For the first years of his perfect life, Jesus was entirely – entirely – dependent upon his parents for all his needs. Here we see God, in the person of Jesus, depending upon Mary and Joseph to feed him, to clothe him, to cuddle him, to clean up his sick and his excrement. This is what human flourishing looks like. 

This is mirrored at his glorious death, too. Prior to his arrest, Jesus asked his friends for support; to stay awake while he prays for comfort. The Gospels go on to tell us that, having been mercilessly tortured, beaten, stripped, and interrogated, Jesus had his cross carried by a man named Simon of Cyrene. After his death, having no tomb of his own, Jesus was buried in the family tomb of his follower Joseph of Arimathea. And this, too, is what human flourishing looks like. 

Throughout his entire life Jesus lived the perfect life of human joy and faithfulness. And this often involved depending upon others and being a burden to them in every way conceivable. We are made to be a burden, then. To depend on others, to be burdensome to them, is to be human.  

To think, then, with Baroness Hale, that my dependency and burdensomeness upon others might somehow serve to underwrite a decision to end my life, is fraught with difficulty for me as a Christian. I simply cannot reconcile her words with the life I see Jesus living in the Bible: a life of joyful, difficult burdensomeness.  

There may be many other reasons why people decide they want their lives to end. But a sense of burdening others ought not to be one of them. Being a burden is not a reason to bring one’s life to an end, because it is the very possibility of our being human in the first place. To need others, to place ourselves into their care, does not make us less human, it makes us more human. And therein lies its glory.
