No mercy on the Megabus

Why is sin such a sickly, sticky thing in the human heart?

“I’m begging you, I’m begging you,” pleaded the passenger. His two large suitcases lying around him, the Nigerian man knelt on the pavement outside the Megabus station. The bus driver stood surly-faced, arms crossed. The passenger’s jacket was ripped where the driver had shoved him off the bus. The passenger had one too many bags; he had not read the Terms and Conditions on his ticket.  

The man groaned – “I must get to Heathrow, I have a flight to catch! I’m willing to do anything – to pay for an extra ticket, to pay the extra bag fee, I have money, see?” He showed the driver his wallet pleadingly, demonstrating his possession of several bank cards.  

A few concerned passengers stepped off the bus. “We don’t have a bag in the hold; we’re happy for this man to have our space.” Another person said, “I booked a ticket but my friend didn’t come – there’s a whole seat’s worth of luggage space available in the hold.” Yet the bus driver would not budge. Even though Megabus has an excess baggage policy, it was down to the driver’s discretion. The driver alone had the power of life and death, to say “yay” or “nay” – to restore a man’s dignity or completely ruin it, along with his jacket.  

As the minutes ticked on, other passengers began to get irate with the Nigerian man – “just buzz off mate, you’re making us late!” “You should have read the rules!” “You’re making the bairns on the bus cry!” Stony faces pressed against the window as the man knelt on the pavement. Even those who had tried to help him left him in the harsh hands of the bus driver and his colleagues, tiny kings in a kangaroo court. For the bus driver, there was no backing down – he was pacing, sweating and red-faced, repeating over and over again to himself his side of the story. And in the end, we left the Nigerian passenger in the heartless hands of bus bureaucracy, wiping our hands of the injury done to him – “we tried.”  

How mucky and murky the human heart can be. 

The whole experience on the Megabus that day left me feeling sick. We all like to think of ourselves as decent folks, as long as we do our “bit”. But on that bus I realized the difficulty: what is “my bit”? Who decides what is “enough”? How quickly a petty issue of baggage can descend into a power play. How quickly do ordinary nice people become a mob when they are outraged or inconvenienced. How mucky and murky the human heart can be. 

The only word that feels strong enough to me to describe this condition is “sin”. This word may sound like a relic of a bygone Britain, but I think it’s as relevant as ever. It’s a serious word, loaded with a sense that the things we do mean more than we know. Sin suggests that I am accountable for how I treat people – not just to my own perception but some higher standard that safeguards the dignity of all human beings. Christians believe that it is God who safeguards our humanity, who sets the standard for how we should and should not treat others. We are accountable “vertically” – to God – as well as “horizontally” to each other.  

It seems to me that “sin” is not a laundry-list of rules but more like a tangled knot of slippery threads – I can’t see where it begins and where it ends, in my own heart or in the world at large. The Christian Eastern Orthodox tradition often likens sin to sickness or a dis-ease of the soul; it infects our reasoning, our emotions and our actions. And that’s why the hurt and pain we cause each other is so “sticky” – no one is left untouched by the effects of the damage we cause each other.  

It was quite clear to me that there were some “sins of deliberate fault” on the Megabus that day – the bus driver’s behaviour was patently unfair and verging on abuse. But I would say sin also flourished in the self-defending logic of the passengers who just wanted to stay in their lane, and for the Nigerian chap to stay in his. Don’t bother me, with your problems. I look after me, you look after you. There were sins of ignorance too – I felt this sick sense in my stomach as the bus pulled out of the station that there was more I could have done, but I didn’t quite know what. All I know is that every person needed mercy on that Megabus, whether we knew it or not. Ironically, the Nigerian man was the most innocent of all.

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.
