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.

Tariffs destroy trust so where do we go next?

Blunt weapons cause a mess in markets and lives.

‘When America sneezes the rest of the world catches a cold’ quipped economists almost a century ago after the Wall Street crash.  A comment that might equally apply to the more than 10 per cent drop in stock markets caused by President Trump’s sudden raised tariffs on imports to the USA.  The impact of the American economy on the world is inescapable.  It represents almost a quarter of global GDP and the dollar is the leading reserve currency, accounting for around 60 per cent of international foreign exchange reserves.  Size is what enables America to bully the rest of the world. 

For decades the American trade deficit has been an elephant in the room and Trump is to be applauded for recognising it and addressing the problem. Unfortunately, the way he has gone about it has caused another, bigger problem. Changing the direction of the global economy is like turning a tanker, it cannot be done easily or quickly, but Trump’s style is to attack, like hammering at a nail.  Every issue in geopolitics looks like another nail, waiting for him to hammer out a negotiated deal.  Full marks for courage, but not for wisdom. The blunt weapon of trade tariffs is designed to bring wealth and power back towards the USA, but blunt weapons often cause a mess, and sure enough a global mess is what we now have.  A US/China trade war with higher prices that could end up stoking inflation and a government own goal.   

Panic selling of government bonds signalling a loss of confidence following Trump’s dramatic tariff boost is reminiscent of the impact of Liz Truss’ sudden and radical UK tax cuts, which were also driven by an ideology, but ended up as a wrecking ball.  Even some of Trump’s backers have warned of an economic nuclear winter.  In the long run, Trump has done the world a favour by highlighting a structural issue that needed correction, but his economically violent methods of addressing it look increasingly unwise.  If a global depression does happen on the back of all this, then coupled with the rise of autocratic and belligerent leadership, we would face a worrying parallel to what happened in the 1930s when the world eventually slid into war.   

Tariffs are like walls, barriers to cooperation and the epitome of economic selfishness.  Make America Great Again is selfishness writ large - a society pursuing wealth and power without the cohesive framework of values that are so essential to cooperation and community wellbeing.  A psychology of self-centredness that damages relationships at the national level.  This is what I find most concerning about Trump’s approach; not just the economics but the long-term legacy of relational damage that could last well beyond his Presidential term. 

Our fears reveal just how much we trust in wealth above everything else, and how much the fear of scarcity affects our mental health.

Michael Schluter in his book The Relational Lens defines five principles, or measures, of relational health.  They are directness, parity, common purpose, continuity and breadth.  Applying those five measures helps us see why Trump’s tariffs are the polar opposite of relational.  He introduced these escalating penalties remotely and not in face-to-face negotiations.  Exploiting the power of America instead of showing respect for the status and needs of other nations.  Tariffs have no common purpose with other countries, only a selfish agenda.  There is no continuity with previous trading protocols.  And it is all purely financial, with no reference to the broader holistic impact.  All in all, a relational disaster.   

Despite living in the ‘first world’ we remain gripped with fear of loss.  Our fears reveal just how much we trust in wealth above everything else, and how much the fear of scarcity affects our mental health. Markets are not entirely rational; they are driven by algorithms that stem from this psychology of greed and fear.  Emotions and trading swing wildly with a herd instinct that often drives behaviour.  As Rabbi Jonathan Sachs said:  

‘Markets have no moral compass; we have outsourced morality to legislation by the State.’   

But the worry now is that the current US administration shows signs of ignoring morality and even riding roughshod over the courts.  No wonder people feel afraid. 

Where can we find hope in all this turmoil?  Is there a better response than gritted teeth and the mantra: ‘this too shall pass’?  I think so.  There is life beyond the market.  Jesus said: ‘life does not consist in an abundance of possessions.’  We can choose to step back and look at all this with the true perspective that money isn’t everything.  We can cultivate gratitude for what we do have.  We can learn contentment.  Yet I feel for those who have experienced financial loss, and don’t want to minimise the reality of hardship.  In fact, something important and practical all of us who are privileged can and should do is to be vigilant in watching out for those who are poor and disadvantaged.  To look after those with a real need for the basics of life and help them through this tough time when economic disruption could make life even harder.  For those with a faith this is part of working out how our faith makes a positive difference where we are. 

Perhaps the supreme irony of this crisis is President Trump’s insistence that Americans must trust him.  Ironic, because the one thing that his tariff actions seem to have undermined more than anything else is trust.  The trust that is essential to the functioning of both markets and civilisation as a whole.  Face to face discussions must be the way forward now, to rebuild trust and find more nuanced, mutual approaches to solving America’s trade deficit.   

There is one person we can always trust though, and his name is written clearly on the American One Dollar bill. In God we trust. Let’s pray that Trump and his America returns to that imperative and turns back to a more Christ centred philosophy of loving our neighbour as ourselves, reflected in a more bilateral approach to diplomacy and agreement.
