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.

A tale of two Romes

The Gladiator sequel’s dream of equality is baloney but telling.

Chariots thunder into a Roman amphitheatre.

I left the theatre quite disappointed by what I had witnessed. The original Gladiator, the Ridley Scott masterpiece, remains one of the most captivating historical epics in cinema. Every time I watch it, I feel I am stepping into another time. The sequel, by contrast, baffled me by how out of time it was, jarring me out of the action by its historical inaccuracies. 

Whether it was the sharks in the Coliseum or newspapers a thousand years or so before their invention, these moments reminded me I was not witnessing an entirely truthful representation of Roman society. Perhaps I am asking too much - a movie is after all, a representation, and may tell us more about ourselves than the era it portrays.  

But Gladiator II’s biggest anachronism isn’t newspapers or sharks, but the presence of Christian values in a pre-Christianised Rome.  

The backdrop for the film is that the evil and insane twin Emperors Geta and Caracalla, have spread chaos across the world, relentlessly conquering foreign lands, imposing their will on others - in other words, doing what Romans usually do. 

Against the emperors are a group of Romans who are tired with all this conquering and violence and want to build a new Rome. Throughout the film, they remind the audience constantly of Marcus Aurelius, the historic Roman emperor from the first film, who had a dream - ‘the dream that was Rome’. Rome would be a republic. But not just any republic.  

Lucius, the hero of the sequel, in his final speech to the Roman army, sets forth what this dream could look like: ‘A city for the many, and refuge to those in need.’  The entire legion lay down their arms and cheer triumphantly for the dawn of this new Rome. 

All of this is starting to sound rather close to home. Perhaps Lucius should march to the US border next.  

We can imagine offscreen, Lucius walks into the Roman equivalent of the World Humanist Congress, to write a charter to declare the worth and dignity of every individual, and their right to freedom. 

Anyone watching who didn’t know their history might be forgiven for assuming that this would mean an end to all the conquering, and the beginning of a just and equal society for all, regardless of gender, social status and nationality.  

Unfortunately, this was not the dream of the Roman republic, even before ‘tyrannical’ emperors started ruling. Many of Rome’s biggest conquests happened during the era of the Republic. Likewise, democracy in Rome did not extend to all people. Slavery was rife. The dream that was Rome, was to have a group of men subjugate the world, rather than just one or two.  

To be fair to Ridley Scott, his Rome has a little bit more nuance than I give him credit. Denzel Washington’s character Macrinus, the gladiator master, stands as a reminder of the hypocrisy of Marcus Aurelius’ ‘dream’. Macrinus was made a slave under Aurelius’ rule, bearing the brand of Aurelius’ visage on his chest, a reminder that he was Roman property. 

The only real equality Rome has – Macrinus points out – is that a slave can violently overthrow an emperor. If equality is going to happen in Rome, it won’t be through reasonable persuasion, but violent revolution. And even then, equality won’t have the final say, but rather the oppressed simply becomes the next oppressor. This is the true spirit of Rome: the survival of the strongest.  

Gladiator II reminds us that the values we find self-evident today, that Ridley puts into the mouth of Lucius and the other protagonists, were not self-evident to Rome. The dream that was Rome is a dream that we have. But how did we come to have this dream? 

We have been shaped by this history in more ways than we know. 

There was another revolution, that Gladiator II does not portray (at least not explicitly). This revolution explains why we look back on history wanting to see ideals of equality and justice. The German philosopher Frederick Nietzsche, atheist and nihilist, writes about it in his work The Genealogy of Morality.  

Nietzsche describes a war that happened between Judea and Rome. Rome was undoubtedly defeated, Nietzsche claims. Now, before we might accuse Nietzsche of further anachronism (the siege of Jerusalem and the destruction of the Jewish Temple in AD70 come to mind), Nietzsche is in fact speaking of a revolution in values.  

He saw that the Roman ideal of ‘the prerogative of the few’: a small group of strong men imposing their will and subjugating others as the master race, was overthrown by the ‘prerogative of the many’ in the ‘slave revolution’. This revolution was brought about by a Jewish man, Jesus of Nazareth, followed by his group of unlikely revolutionaries. 

At the centre of this movement was one central image: a man dying on a Roman cross, a punishment meant for slaves and criminals. 

God in human flesh dying as a victim of oppression, was an image that gave power to the powerless. 

Nobility was no longer be found in inflicting suffering, but in enduring it for the sake of others. 

 Historian Tom Holland writes in his book Dominion: The Making of the Western Mind

‘The spectacle of Christ being tortured to death had been bait for the powerful. It had persuaded them … that it was their natural inferiors, the hungry and the humble, who deserved to inherit the earth’.  

Holland traces this revolution and the ways in which this counter-narrative slowly seeped into Western culture, implanting a concern for the powerless. The welfare state, universal human rights, movements like #MeToo all find their source in this world-rupturing event. 

Holland writes elsewhere: ‘The wellspring of humanist values lay not in reason, not in evidence-based thinking, but in history.’   

We have been shaped by this history in more ways than we know. 

Our generation suffers from cultural amnesia. We forget the reason for how we reason today. Our desire to see Rome (and our own nation, for that matter) become a home for the many and refuge to those in need, is a desire that has been shaped by Christian values.
