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.

Magi: where did the wise men come from?

The origin story of the Middle East's ancient king makers.

You’ve probably heard they weren’t really kings, but the wise men or magi had some impressive royal connections. Far from being one-off royal visitors to the infant Jesus, the magi had a long history of involvement with monarchy, crossing paths with illustrious kings including Cyrus the Great of Persia, Alexander the Great and the Roman Emperor Nero.

Originally a tribe of the Medes who lived in Northern Iran 600 years before Jesus’ birth, the Persian magi were hereditary priests. Writing around 425BCE, Greek historian Herodotus tells us how these magi became known throughout the ancient Middle East for their ability to interpret dreams and knowledge of the stars. They were followers of the Zoroastrian religion, and were responsible for the holy fires central to Zoroastrian worship.

To the Greeks, the Zoroastrians and the magi were exotic objects of fascination. Many later Greek written philosophical and occult works claimed Zoroaster (or Zarathustra) as their author. Much like some twentieth century Western conceptions of Hinduism and Buddhism, the Greek and Roman conceptions of Persian religion often had only a passing resemblance to the original. This may have included the "mystery cult" of Mithras that would become popular throughout the Roman Empire in the first century. This also means that references to 'magi' may not refer to the Persian magi, but to other astrologers or dream interpreters who lived to the east of the Mediterranean.

A hundred years before Herodotus, we find the first mention of magi in the bible, in the Book of Daniel. This was the period of Jewish exile and captivity in Babylon. Jehoikim, King of Judea and descendent of Kings David and Solomon, was defeated in battle and killed by Nebuchadnezzar II of Babylon. Jerusalem and its temple were destroyed, and many Judean nobles were taken as prisoners. Daniel was one of these hostages and is taken to the Babylonian court, where God gives him the ability to interpret the king’s dreams. Impressed by his abilities, Nebuchadnezzar puts Daniel in charge over all his wise men. It’s unclear what relationship these Babylonian ‘magi’ had with the Medean ones, but strong Medean influence on the Babylonian court suggests that the Babylonian wise men could well have included Zoroastrian magi.

Daniel remained in the Babylonian court, until the Babylonians were invaded by Cyrus the Great, who allowed the Jews to return from exile and to begin restoring Jerusalem.

Cyrus' Persian Empire lasted for two hundred years, until it was invaded by Alexander the Great and his army in 331BCE. Alexander sought the advice of magi, but had many of them violently killed and extinguished their holy fires when he razed the Persian capital, Persepolis in revenge for the Persian destruction of the Acropolis by Xerxes 150 years earlier. Alexander’s Greek successors were characterised by bloody rivalries and in-fighting and were later overthrown by the Parthian empire, which would become Rome’s most formidable rival to the east. The magi consolidated their king-making reputation during the Parthian period, with a council of magi (the Megistanes) responsible for choosing Parthian kings.

The knowledge they have is broken, it’s a messy blend of wacky occultism, astronomy, maths topped up with an unhealthy obsession with royalty. The knowledge we have is broken too.

By Jesus' day, there were ‘magi’ throughout the Middle East, and it was in this context that Roman historian Pliny the Elder records the journey of Armenian magi to visit Emperor Nero in 66CE. By this time Parthia and Rome were a century into their protracted struggle and had just fought a five-year war over the Armenian succession. Despite suffering a humiliating defeat, Rome saved some face through a very one-sided treaty that had Parthia choose the next Armenian king, but with the Roman Emperor getting to place the crown on his head! Nero turned this to his advantage by having the new King Tridates I come to Rome to receive his crown. Tridates, who was a Zoroastrian priest as well as a king, came with a huge retinue including other magi and thousands of horsemen to receive his crown. The huge procession culminated in the magi king bowing before the emperor and acknowledging him as his god.

The visit of the Armenian magi has clear resonances with the familiar account of magi visiting the infant Jesus found in Matthew’s gospel. Given the many embellishments added to the magi story over the centuries, it's hardly surprising that some have suggested that the magi story was a fabrication and a remixed version of King Tridates’ visit to Emperor Nero. It’s a compelling theory, but I’m not convinced by this. If magi were stock characters in the ancient near east, and were also really interested in monarchs (who were often also treated as gods), then it wouldn’t be that surprising that there’d be more than one royal magi visit with emotionally charged religious overtones. What makes a fabricated magi story less likely to me is what the gospel writer Matthew’s Jewish audience would have thought of the magi. Although the Greeks and Romans were enthusiastic about foreign gods and exotic wisdom, first century Jews were not. To them and to early Christians, the magi would have been charlatans and followers of a false foreign god. A visit from some foreign astrologers would have been an embarrassment rather than the type of story you'd choose to make up.

So, who were the magi in Matthew's gospel? The two dominant theories have been that they were either Persian or else they were a later fiction. More fanciful theories include origins in India, China and even Mongolia. Another perhaps more realistic possibility, convincingly argued by Fr Dwight Longernecker in The Mystery of the Magi is that the magi were from the Arabian kingdom of Nabatea. The Nabateans were known for using irrigation to farm the desert and for controlling the trade routes across the Arabian desert. Two cash crops in which Nabatea dominated trade were frankincense and myrrh. The wealth generated from this lucrative trade was used to build Petra, the world-famous valley city of rock-face monuments. The Nabateans had close connections with Israel and may have been familiar with the prophecies of Daniel and Isaiah. They would also have been interested in the Judean monarchy and would have been natural visitors to the paranoid king Herod. Herod's mother was a Nabatean princess and the Nabatean king Aretas IV needed to shore up favour with Herod so the Nabateans would have had an interest in any new King of the Jews.

Barring some improbable Indiana Jones style archaeological discoveries, we’ll never know for sure who the wise men from the east were. But to me there’s something deeply fascinating about these mysterious visitors to the infant Jesus. Partly they seem to represent higher things – with their wisdom and wealth correctly put in divine service. It can seem as though their excellent learning and astronomical skills have cracked a cosmic puzzle, with the magi following the star and dodging a despot to find the baby at the end of the treasure hunt. This doesn’t hold up - the magi’s knowledge isn’t the object of wonder. The knowledge they have is broken, it’s a messy blend of wacky occultism, astronomy, maths topped up with an unhealthy obsession with royalty. The knowledge we have is broken too. But God uses the foolish things to confound the wise, and inside the crackpot mess of horoscopes and divination, God leaves the magi an invitation. To accept the invitation is to take a risk – to risk the long journey, the wrath of Herod and even to risk being wrong. But as they accept this invitation, they realise its an invitation to meet God Himself.
