Why smell jumps the queue when it comes to memories

Smells hardwire deep into the brain, writes Henna Cundill, as she explores why they jump-start such vivid memories.

When I was a 22-year-old undergraduate my mother died quite suddenly. I can't remember the name of the undertakers we used, nor the chaplain who took her funeral. I can no longer visualise what any of their faces looked like. I know I visited the chaplain’s house to plan the funeral, but I can't remember exactly where that house was. What sticks is that the day of the funeral was a sultry summer's day, and both the chaplain and the undertakers smelt of perspiration. To this day there are moments where I catch that same whiff of man-sweat in some other location, and for a fleeting second, I am a bewildered 22-year-old once more. 

Here is another memory. I attended a tiny, rural Church of England primary school in the middle of England. At the end of each school year, all of us donned our little Wellington boots, which smelt faintly of slurry (since this was dairy-farming country) and sweaty feet. Then we lined up in a crocodile and trudged through the bluebell-wood (damp leaves) and skirted the edge of fields (silage, which stings the nose) covering the mile or so between our school building and the village church. 

We would enter the church grounds through the back field, hurrying through an eerily muffled graveyard with tombstones towering far above our heads and the grass disturbingly lumpy beneath our little feet. To the chidings of “Quickly!” and “Quietly!” we children scurried down a gravel path, away from this unsettling place of death, to reach the cool sanctuary of a little church, and the comforting smells (for me, at least) of damp stone and dusty hymnbooks. 

Others may not have the same associations, but for me the smell of dust and damp stone will always cry “safety!” and the reassurance that “there are no ghosts in here!” in contrast to that troubling graveyard. From death to life. Yet, at the same time, getting stuck with my nose close to some man’s whiffy armpit on the Tube will forever insinuate that I am just a child pretending to be a grown-up, out of my depth, overwhelmed with one thousand decisions to make (“What flowers do you want for her coffin?”) and no-one to advise. In the midst of life, death again.  

On reflection I will know that my emotions are being manipulated by my nose, in ways which are more or less than helpful depending on the circumstances.

Of course, I am not 22 years old and lost anymore, no matter what that man’s armpit tries to tell me. My rational mind knows better, but my rational mind doesn’t get a say – or doesn’t get the first say anyway. This is because smell is the only one of our senses that bypasses the thalamus (the brain’s ‘filtering gate’ that decides which part of the brain needs to respond to sensory input) and goes straight to the limbic system, where emotional memory is stored.  

Sometimes it is very obvious that this is taking place, such as in the examples given above. On reflection I will know that my emotions are being manipulated by my nose, in ways which are more or less than helpful depending on the circumstances. But it can happen in more subtle ways too. Supermarkets infamously pump out smells to influence our buying choices, and we’re trying to sell our house right now, so we’ve been brewing a whole lot more coffee than we ever usually would.   

Intriguingly, scientists don’t really know why the human sense of smell jumps the queue when it comes to cognitive processing. There are biological theories, such as that the smell of predator could wake up our ancestors while they were sleeping and/or could allow them to follow a scent trail quickly when fleeing danger or seeking food. There are social theories too, such as that we don’t have a lot of good words to describe smells, so the brain just doesn’t bother trying to analyse them. Whatever the truth of the matter, the reality is that (whether we like it or not) our noses are an emotional trip-hazard.  

When I walk through those great oak doors there is a moment, a glitch in the matrix, when the unmistakable smell of church hits my nose. Dust, damp… a little hint of mouse. 

I can’t help wondering what this tells me about my religious practice. Do I go to church because I have made a cognitive decision to worship God each Sunday? Or do I go to church because I am following my nose, getting away from a world full of armpits and responsibilities to a place where I am a seven-year-old girl, all gingham dress and wellies, feeling safe. If so, does it matter?    

Truth is, my mind can give me a dozen reasons not to go to church every single week. In fact, two dozen reasons. More. It has always been a busy week; I’m always behind on work. The house always needs a sort out and the car is never washed. But because certain congregation members are normally counting on me for certain things, and because I’m still pretending to be a grown up, I typically drag myself out the door, and off to church I go.  

And week on week, without fail, when I walk through those great oak doors there is a moment, a glitch in the matrix, when the unmistakable smell of church hits my nose. Dust, damp… a little hint of mouse. My body registers this before my mind; my shoulders drop a little of their tension. Even if it’s just for a fleeting moment, I start to feel that I know for sure what is absolutely real in my life and what is just pretend.  

Is this knowledge irrational – since it doesn’t come from the cognitive part of my mind? Or is there a God who knows that the cognitive part of my mind sometimes tells me all sorts of untrue and unhelpful things. Is there a God who is choosing to reach out to me in more subtle, more ancient ways?  

I can only wonder if I have been following my nose all this time, without even noticing. Drawn along by an ancient scent trail that leads me time and time again…this way…and that way…until I reach a place where there is safety, and bread.

Roll on AI, you'll make us more human

I’m not necessarily stupidly optimistic about AI, but there’s a tentative case to be so.

Daniel is an advertising strategist turned vicar-in-training.

I still come across people who insist that there are simply things that AI (artificial intelligence) can’t and will never be able to do. Humans will always have an edge. They tend to be journalists or editors who will insist that ChatGPT’s got nothing on their persuasive intentionality and honed command of nuance, wit, and word play. Of course, machines can replace the humans at supermarket check-out tills but not them. What they do is far too complex and requires such emotional precision and incisive insight into the audience psyche. Okay then. I nod, rolling my eyes into the back of my head.  

At this point, it’s just naive to put a limiter on the capabilities of what AI can do. It’s not even been two years since ChatGPT3 was released into the wild and started this whole furore. It’s only been 18 months and OpenAI have just launched ChatGPT4 which can produce a whole persona who can listen, look, and talk back in such a natural and convincing voice that it may as well be a scene from the 2013 film, Her. A future where Joachim Phoenix falls in love with the sultry AI voice of Scarlet Johannsson doesn’t seem too far off. We have been terrible at predicting the speed at which generative AI has developed. AI video generation was one of the clearest examples of that in the last year. In 2023, we were lauding it over the AI models for generating this surreal, nightmarish scene of Will Smith eating spaghetti. “Silly AI! aren’t you cute.” we said. We swallowed our words earlier this year, when Open AI came out with Sora, their video generation model, which spat out photorealistic film trailers that would feel at home on the screens of Cannes.  

There might be limits, but that ‘might’ gets smaller and smaller every single month, and we’re probably better off presuming that there is no ‘might’. We’ll be in for less surprises if we live from the presumption that there will be AIs that will make better newspaper editors, diagnostic radiologists, children’s book writers, and art-directors than most, if not all, humans.  

With the mass reproduction and generation capabilities of AI, we may recognise that we crave the human touch not because it’s better but because it’s human

I promised you a “stupidly optimising” take on this. So far, I’ve given you nothing but the bleak dystopian future where the labour market collapses and humans are dispossessed of all our technical, editorial, and creative skills. Where’s the good news?  

Well, the stupidly optimistic take is this: the dispossession of all our human faculties by AI will force us to embrace the truest and most fundamental core of what makes us valuable - nothing other than simply our humanity. The value of humanity goes up if we presume that everything can be done better by AI.  

In 1936, the German art critic, Walter Benjamin, prophesied the apocalyptic collapse of the art market in the essay: The Work of Art in the Age of Mechanical Reproduction. It was at a time when photographic reproduction of paintings was becoming a mainstream technique and visitors to a gallery could buy a print of their favourite painting. He argued that the mass reproduction of paintings would devalue the original painting by stripping away the aura of work - its unique presence in space and cultural heritage; the je ne sais quoi of art that draws us to a place of encounter with it. Benjamin would gawp at the digital age where masterpieces would be reduced to default iPhone background screens, but he would also be surprised by the exponentially greater value the art market has placed on the original piece. The aura of the original is sought after, all the more, precisely because mechanical reproduction has become so cheap. Why? Because in a world of mass reproduction, we crave human authenticity and connection. With the mass reproduction and generation capabilities of AI, we may recognise that we crave the human touch not because it’s better but because it’s human. And for no other reason.   

We continually place our identities in whatever talents we think make us uniquely worthwhile and value-creating for the world. 

What are we to make of the AI trials happening in the NHS which spot cancer at rates significantly higher than any human doctor. The Royal College of Radiologists insists that “There is no question that real-life clinical radiologists are essential and irreplaceable”. But really? Apart from checking the AI’s work, what’s the “essential” and “irreplaceable” part? Well, it’s the human part. Somebody must deliver the bad news to the patient and that sure as hell shouldn’t be an AI. Even if an AI could emulate the trembling voice and calming tone of the most empathic consultant, it is the human-to-human interpersonal exchange that creates the space for grief, sorrow, and shock.   

Think utopian with me for a moment. (I know, very counter-intuitive for us). In a society where all our technical skills are superseded, the most valuable skills that a human could possess might be the interpersonal ones. Empathy, compassion, intentionality, love even! The midwife who can hold the hand of a suffering first-time mother could be a more respected member of society than the editor of an edgy magazine or newspaper. As they should be! That’s a tantalising and stupidly optimistic vision of an AI future, but it’s a vision that aligns with what we know to be the true about ourselves. In our personal and spiritual lives, we already recognise that the most valuable aspects of our lives are our human relationships and the state of our inner selves. People on their death beds reflect on what kind of person they’ve been and reach out for the hands of their loved ones - not for their Q4, 2011 balance sheet. Our identities are shaped most deeply by our relationships and our character, and yet, we continually place our identities in whatever talents we think make us uniquely worthwhile and value-creating for the world. It’s good to create value, it’s nice to be good at something, and it’s meaningful to leave a lasting impact, but it is delusional to think that those things make us valuable. Our dispossession by AI might be the dispelling of these delusions! 

In a few decades, there may be nothing that humans can do better than AI, other than simply being human in the world

At least on a philosophical and spiritual level, being stripped of our human exceptionalism might be the most liberating experience for a society that has devalued and instrumentalised humanity to being glorified calculators. Being dispossessed is the truest thing about all of us. We are all being dispossessed daily by the slow march of time. The truest thing about us is that we will, one day, be wholly dispossessed by death itself. That was Heidegger’s fundamental insight into the human condition and this feeling of dispossession is the root of our anxiety and fear in the world. This might be part of the anxiety and ick we feel towards AI. Being dispossessed of our creativity and technical ability is a kind of violence and death against ourselves which we rage against. We can rage against it politically, socially, and economically, but there might be something helpful about resisting the rage from a psychological and spiritual point of view. Experiencing this dispossession might be the key to unlocking an authentic human existence in a world that we can’t control.  

I believe in human creativity. I believe that what we make is valuable. I believe in the mesmerising aura of art, cinema, music, and every other beautiful thing that we get up to in the world. I believe in the unique connection between artist and audience and the power of blood, sweat, and tears. I believe in the beautiful and tortuous self-violence of creativity to make something that will make my heart tremble and transport me to places never imagined. I believe in the intuitions of an editor to make the cut at precisely the right moment that suspends the tension and has me gripping the seat. I believe in the bedroom teenagers recording their first demos on Garageband, or the gospel choir taking their congregations to heaven and back. Now, more than ever, I believe in these miracles.  

But my belief is not anchored in any unique technical excellence, or some hubris about our exceptionalist mastery of craft. It is rooted in the profound humanity of it all, which radiates, however dimly, with the image of the divine. Writing poetry, humming a new melody, baking a cake or, even discovering a new mathematical conjecture can feel like “divine inspiration” as the leading mathematician, Thomas Fink, asserts. Or as the Romantic German theologian, Schleiermacher, so rhapsodically expressed, it can feel like the soul being “ignited from an ethereal fire, and the magic thunder of a charmed speech’" from above. This transcendent human experience is something that AI can’t usurp or supersede.  

In a few decades, there may be nothing that humans can do better than AI, other than simply being human in the world. However, Once we are stripped of everything, we won’t find ourselves naked in the dark, or at least, we don’t have to. We can stand before the world and God with the works of our hands - finite, flawed, and dispossessed - and yet, inestimably valuable and worthwhile for the simple fact of our mere humanity. 

 

*This article was something of a thought experiment. It’s far more natural to take a sandwich-board, bullhorn-wielding apocalyptic take on the rise of AI. The powers-to-be at Microsoft and OpenAI have their own ideological agendas, and it’s not unlikely that in this technological cycle, we’ll live through a profoundly destabilising labour market. We are right to fear the consolidation of wealth to supreme tech feudal lords with their companies of AI employees who cost a fraction of real humans. Civilisational collapse! What I wanted to suggest here is that there might be a unique spiritual and philosophical opportunity afforded to us as we continue to experience the break-neck development of AI and its encroachment into everything we once held as uniquely human skills.*
