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.

Nigeria’s terror survivors share their stories

This violence is not gruesome fiction, it’s reality.

Something is happening. And nobody is talking about it.

Nigeria, the big and beautiful ‘Giant of Africa’, is becoming a place of increasing terror for the hundred million Christians who call it home. Since 2000, 62,000 people have been killed for having a Christian faith. Eight-thousand people were killed in 2023 alone. These staggering numbers mean that more Christians are being killed in Nigeria than in every other country combined.

The violence is as extreme as it gets. And yet, very few of us know that it’s happening.

When it comes to the Nigerian government and media, the relentlessly brutal attacks are seemingly hidden in plain sight; undeniable and yet somehow unstoppable. While, in the UK, we appear to be entirely unaware. This violence is out of sight, and therefore largely out of mind. The reasons why are admittedly complex, as outlined by Chris Wadibia. Nevertheless, the violence being carried out toward the Nigerian people, particularly those living in the Northern states, surely deserves our attention.

Earlier this year, I took a trip to Northern Nigeria. While I was there, I got to know a group of people who had endured unimaginable trauma, largely because of their Christian faith. Every day, they would bravely tell their stories – who they were and what they had experienced. Every day, I looked into the faces of children who had lost parents, parents who had lost children, husbands who had lost wives, and wives who had lost husbands. All of a sudden, the bewildering statistics were people before me – people who were having to live with the images of their loved ones being ‘butchered’ before their very eyes. Their villages being burnt down. Their lives being turned upside down by militants with assault rifles and machetes.

The only reference I had for stories such as the ones I was hearing were apocalyptic movies. But these things happened. They happened to the people sitting across from me. This violence is not the stuff of gruesome fiction, it’s the stuff of reality.

As she was running, she came across a woman who has hiding herself because she was giving birth to twins. This mother handed the babies to her and begged her to get them to safety...

I met one woman, she was incredibly gentle and kind, and told her story with a composure that’s hard to fathom. She was working on her land along with her husband and mother-in-law, a totally run-of-the-mill day. They were so engrossed with the task at hand, they didn’t notice that their village was being attacked by armed ‘Fulani’ militants (the majority of the violence being carried out in Northern Nigeria is at the hands of Islamic extremist groups such as Fulani militants, Boko Haram and ISWAP - Islamic State in West African Province). She looked up to find herself face-to-face with two attackers and despite their command for her to surrender to them, she ran, as did her husband and mother-in-law. While she was running, she could hear bullets flying past her head and the screams of her mother-in-law. Making it to a neighbouring village, she gathered help and eventually went back to find her husband and mother-in-law. Both of whom were stabbed and killed that day.

The Fulani militants now have control over her village, and she told us how she’s been praying that she would be able to forgive these men for what they’d done, as she is now forced to live alongside them. And so, she felt proud because she had recently been able to respond to one of the men as they greeted her.

There was another woman, she was strong and defiantly compassionate. Her story is laced with horror. She studied at a university – the discrimination she experienced there meant that a course that was supposed to be four years long, took her eight years to complete. In 2014, Boko Haram attacked the university – while she was trying to escape, her friend was shot and ‘hacked at’ while he refused to deny his Christian faith. She recalls how his last words were ‘I’m happy. I’ve saved lives today. And I have Jesus’.

He died and she continued to run. As she was running, she came across a woman who has hiding herself because she was giving birth to twins. This mother handed the babies to her and begged her to get them to safety, as she did so, she heard the mother being shot behind her.

She ran those twins to Cameroon, leaving them in safety, and now lives in a rural Nigerian village where she teaches the local children. Her Christian identity is no secret, and so faces continual danger. Her crops were burnt to the ground and destroyed, twice. And the villagers have tried, repeatedly, to get her to leave. One night, she came face to face with young men with bats and machetes who threatened her life – she told them – ‘you can’t scare me. I have seen the Lord’.

And they left. Remarkably, that village is still her home.

One heart-wrenchingly-young girl told us how, while she sleeping – she was awoken by her father who told her that they needed to run, they were under attack. She ran, hand in hand with her father, while her mother carried her younger brother. While they were fleeing, her dad was shot and killed. Her mother pried her hand out of her father’s and buried both her and her brother in sand, instructing them to stay hidden. The next day, they found that their house, their crops, their entire village had been burnt down.

This is what is happening. This is what we are not seeing.

While we are not seeing this violence, they are not seeing an end to it.

Since my return, I have met with a man who bears the physical scars of his trauma. He thought his house was being pillaged by armed robbers - it was only when they led him, his brother and his father outside, made them kneel with their hands tied behind their backs, and demanded that they denounce their Christian faith that he realised he was being attacked by Boko Haram. It was a regular evening, he was putting together a lesson plan for his class the following day, and now he was kneeling before an executioner. His father refused their demand, and they beheaded him. His brother also refused, and they took a blade to him, too. Then it was his turn, and while his mind was filled with thoughts of death and how much this was about to hurt, he also prayed that these men would be forgiven for what they were doing. Taking after Jesus, who forgave his executioners mid-execution, this man continued to pray as he felt the blade in his neck.

Left to bleed to death, miraculously, both him and his brother survived. Now, his scar tells an astonishing story.

This epidemic of violence seems to reside under our radar. It’s not quite catching our eye, is it? And, as a result, is not quite receiving the force of our outrage nor benefiting from the depths of our compassion. So many of the people that I met expressed a feeling of being neglected – like they’re suffering in deafening silence. While we are not seeing this violence, they are not seeing an end to it.

What’s happening in Nigeria is a crisis, one that we must acknowledge.
