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.

How tech harvests our humanity

The second in a three-part series exploring the implications of technology.

James Lawrence

James is Canon Missioner at Blackburn Cathedral. He researches technology and theology at Oxford University.

In the first article, I painted a picture of the ordinary person using modern technology, for example, social media on a smart phone. I noted that advocates for modern technology seem to have two basic principles: that technology is natural and neutral. In this next article I want to introduce the philosophy of Martin Heidegger and show how he pushes against these two basic principles and invites us to think again about modern technology. Heidegger’s instinct, as a twentieth century philosopher, is to be suspicious that things are not as they seem, he casts his suspicious gaze over modern technology and sees a way of being that technology encourages that exists underneath the technologies that we use every day.

What Heidegger wants to show us about modern technology is not related to specific concerns about particular technologies but instead a general suspicion about the ‘essence’ of technology, or, you could say, the spirit of technology. He doesn’t want us to immediately jump to pragmatic questions about how to use technology, as if the primary question is how to make any given technology better or more moral. Instead, Heidegger wants us to take modern technology together as a whole and ask, “What is the essence of this?” Heidegger’s contention is that “technology is not an object or set of objects, nor a way of handling objects with tools, but a form of being the world. It is not something we choose to refuse, but the environment in which modern humans come into existence.”

Heidegger argues that underneath any piece of tech that we might use in our day-to-day lives, technology at its core has already completely changed the way that we as a society understand and interact with the world and everything in it. We live in a technological age and as members of a technological society and so we have been shaped by (to use Christian language, we have been ‘discipled’ by) the spirit of the age to see the world around us. Heidegger suggests that we now see the world as broken down into useable bits that can be categorised and reformed to suit our needs. As Mark Wrathall puts it, the essence of technology is to train us to “experience the world as calling on us or drawing us. To transform everything into stock pieces, so that they can be placed into a vast inventory of options.”[2] Growing up in a technological society means that we see the whole world as an Amazon warehouse a place of seemingly limitless options that can be called upon depending on our needs and quickly delivered.

A piece of technology such as the smartphone points to a wider ‘spirit’ of technology which intends to position everything, even human beings, as replaceable resources within a larger system.

The central word that Heidegger uses to describe the essence of technology is gestell which is not an easy word to translate into English, but two possible translations would be ‘positionality’, or ‘enframing’. His point is that the essence of technology is to remove objects, people, and things from their natural environment and position them so that they might become useful, a resource, available for our manipulation. When Heidegger says that the essence of technology is gestell he is pointing to the way that modern technology extracts objects from their contexts and turns them into a quarry to the plundered. There are of course obvious ways in which humanity has always extracted resources from the natural world: we have always quarried for energy (coal, oil etc) or chopped down forests for wood. By claiming that the essence of modern technology is gestell, Heidegger wants us to notice that in the modern world, it’s not just quarries or forests that we mine for resources but now anything and everything can be turned from being a singular object in the world into a recourse for extraction. Everything has become what Heidegger calls “standing reserve.”

Think again of a smartphone, it is just one of the billions of devices that sit on shelves or, having already been purchased, live in someone else’s pocket. Inside each device are thousands of transistors and circuit boards each of which again are stockpiled in warehouses ready to be replaced if needed or used for some other purpose. Your phone is connected to a network of nodes each of which can be replicated or replaced if needed, no node is unique. Your latest phone has no unique or prize relation to you, it’s just the latest upgrade which will be recycled in a year or two when the next upgrade becomes available. The person from whom you bought the phone is equally replaceable, just a faceless employee completing a set of controlled and pre-arranged tasks that are designed to be completed by anyone and no one in particular. Likewise, you as the consumer are considered to be little more than “standing reserve” by the companies that supply you with your smartphone and access to their networks. One of many millions of nodes in their system that has been analysed so that your preferences can be expertly mapped to the range of services that they provide. Within that system, you are completely replaceable. A piece of technology such as the smartphone points to a wider ‘spirit’ of technology which intends to position everything, even human beings, as replaceable resources within a larger system: “Every item within this standing reserve is reduced to a position, actively waiting to be called on. Heidegger insists this is no judgment on the radio, the internet, or the smartphone user. It is just the way in which the essence of modern technology interacts with humanity… Heidegger provides a diagnosis of our modern age and the way in which we humans have placed ourselves under the sway of modern technology, as a resource standing within a network which seeks, ultimately, to place, represent, and think of every entity as an object within an all-encompassing system.”

Let’s return to the original thought experiment at the start of the first article: a mother playing with her child, who immediately reaches for her phone to capture the moment when her child does something particularly cute. An advocate for modern technology, like Steve Jobs, may look at that interaction and see only the benefit: a mother wanting to remember a beautiful moment with her child extends the capacities of her brain using a digital tool to aid her memory. But Heidegger would be more suspicious, he would look at that moment and argue instead that the essence of technology is to turn everything, even a precious moment with a cute baby, into a resource to be used at a later date. The unique moment of joy and delight between parent and child becomes caught and codified such that it can be found and replayed at will or easily replicated to send to others. At the extreme end of the spectrum are so-called content creators who reduce themselves to just another resource to be harvested on social media.

So that is Heidegger’s diagnosis of our technological age, in the final article in this series we will consider Heidegger’s solution and consider what a particularly Christian response to Heidegger’s diagnosis might look like.
