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.

Can the economy work for the common good?

Adrian Pabst on the economic framework that is universal yet particular about people.

Laurence Fletcher

Adrian Pabst is Professor of Politics at the University of Kent, and deputy director at The National Institute of Economic and Social Research. His lecture on Just Economy? Catholic Social Thought, Mutualism and Roads Not Yet Taken, was a highlight of the Lincoln Lectures series, organised by Together for the Common Good. Financial markets journalist Laurence Fletcher talks with him to discover more about his thinking.

There is no shortage of commentators ready to point out the apparent deficiencies in the UK’s economy. Widespread in-work poverty, poor productivity growth, regional inequality and a perceived reluctance among employers to train up British workers are just some of the accusations that can be levelled.

But finding realistic, workable solutions is more difficult, as successive governments have found. Is the answer to be found in having higher levels of tax and government spending, or lower? Should governments be intervening more, or give more room for free markets to work? With a general election on the horizon, and with issues of economic growth, government spending and taxation likely to feature prominently, such questions are particularly pertinent.

Offering one alternative way of tackling the problem is Professor Adrian Pabst, a political scientist at the University of Kent, who is an expert on so-called Catholic Social Thought. This approach, which was developed in the 19th century and draws from the Bible, focuses on the dignity of the individual, care for others and the common good, with the aims of social renewal. It provides a framework for thinking about big topics such as international relations, the economy and the environment, and Pabst believes it has much to say about our economy today.

Catholic Social Thought “is very particular. It always speaks to the moment. And it’s highly universal because of it,” he said in a recent interview. “This is what the world is like and this is how we must act.”

Pabst rejects both the idea that everything is fine with our economy (“mythical stories about things working”) and the belief that “everything going to hell in a handcart”.

Instead, his approach is to look at some of the apparent contradictions in our economy - strengths alongside related weaknesses. For instance, how can a country be rich but have poor citizens, or have a very high output of goods and services while many people do not partake in them? Or how can many people have become worse off in recent years, even though wages are growing? Or how can the UK boast an “incredible” City of London that is one of the world’s top financial centres, yet have people without access to capital?

“We have to be realistic about where we are - a low wage, low growth, low productivity economy. We can pay people higher wages over time if we increase productivity. That comes from investment,” he said.

Free markets have at times been heralded as either the answer to all our problems by some on the political right, or the cause of so much misery by some on the left. But Pabst’s approach is more nuanced. Markets should not simply be “the engine for ever-greater inequality”. But, crucially, they are not inherently bad in and of themselves, and often the problem is instead down to a market being stacked in one side’s favour.

“Markets are not one thing,” he said. “They are an outcome of ownership, regulation… There is not a problem with markets per se, but it’s the wrong regulation, ownership concentrated in a very few people.

“There are lots of things we can do much better. But if we replace the market with the state, we’d just be doing [communism] and ultimately we’d be poorer,” he added. “The question is, are we putting society first?”

(As an aside, he also takes a more nuanced view on former Prime Minister Margaret Thatcher, who he believes brought both positives and negatives).

Big tech firms are “oligarchies accountable to no-one. It’s simply not a tenable position. They’re like media companies yet they’re not subject to media laws… We’ve allowed them to build private infrastructures. It needs to be tackled.”

So what would Pabst actually change?

For starters, he believes that too much capital is directed towards the wrong purpose, namely financial speculation. While some would argue that speculation plays an important role in the economy, for instance in price discovery in markets or in taking the other side of the trade, say for farmers who want to hedge crop prices, Pabst is keen to see the economy produce “goods and services that have real worth”. Significantly for how society is structured today, he argues that we do not need “a class that lives off assets at the expense of everyone else”.

Other areas also need to change, he believes. Loopholes should be closed to make it harder for companies to use agency workers rather than employing people. Trade unions need to be encouraged and improved. A national investment bank, grouping together the existing, disparate pots of money, could direct capital to sectors and regions where it is needed. As is already the case in Germany, companies and society would both benefit from having employees on their boards.

More economic decisions can be devolved from national government to a local level, but challenges such as climate change or regulating the big, powerful technology companies - which he describes as “modern day plutocracies” - should be tackled at a higher level.

Big tech firms are “oligarchies accountable to no-one”, he said. “It’s simply not a tenable position. They’re like media companies yet they’re not subject to media laws… We’ve allowed them to build private infrastructures. It needs to be tackled.”

And (more of a comment on the US than the UK) he sees little value in companies reporting earnings quarterly, which he said is driven by “short-term profit maximisation”.

Intriguingly, Pabst does not shy away from taking a stance on one of the most divisive issues of our times: immigration.

Catholic Social Thought, he explains, is humane and pro-immigrant. But, to break with what he calls “a low wage, low skill model”, mass economic migration is to be discouraged, because it is detrimental to both the sending and receiving countries.

“[We say] yes to refugees, to asylum. But no to mass economic migration,” he said.

So, going into an election, how likely are we to see things change for the better?

Rather than being optimistic - the belief that eventually things will get better - Pabst is hopeful, because he believes that things could be different, but he is not necessarily expecting it.

“I remain hopeful,” he said. “I just don’t quite see who’s going to do it.”
