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.

How to pick an economic approach that really adds up

Assessing doughnut economics, Paul Williams asks what’s the economy for and who does it really serve?

“Anyone can see that our economic system is broken.”

This is the conclusion of Kate Raworth, author of Doughnut Economics, and her assessment has garnered positive endorsements from figures as diverse as George Monbiot, Andrew Marr and Sir David Attenborough.

Yet to judge by the discussion surrounding the Chancellor’s Autumn Statement, our political class is not included in this broad perspective that Raworth claims. In what is widely understood as the early skirmishes of an election campaign, anticipating the moment when the country’s voters have another opportunity to indicate the direction of travel they hope for, the focus is on who will be better or worse off by this or that tax cut or benefit change. If anything is broken it is not the economic system but something like ‘the government’s economic management’ (Labour) or ‘public sector productivity’ (Conservative).

If you are worried, as Raworth is, by “relentless financial crises,” “extreme inequalities in wealth” and “remorseless pressure on the environment” then it seems that both the government and the opposition believe that the solution is more economic growth, albeit with some barely discernible differences in fiscal and regulatory policy.

Our contemporary political discourse is dominated, regardless of party, by the mainstream economic paradigm in which the market generates economic growth and the state functions to keep things on track by taxing and redistributing some of the surplus to those who for whatever reason didn’t do as well as others in the process. It also provides some additional incentives to business and other organisations to act in the public interest, for instance by subsidising green energy or taxing fossil fuels. Both parties, it seems, support this approach. The difference between them concerns how best the state manages the economy to get the most out of it, how the resulting surplus is distributed, and what kind of further incentives are needed.

For Raworth, on the other hand, the first thing to ditch is the assumption that economic growth is the right goal to pursue. The ‘doughnut’ of doughnut economics is an alternative to GDP as a measure of progress. It name is derived from the visual depiction of the idea of an economy that operates in the space within two limits – ensuring the human rights of each person on the one hand, and staying within the means of the planet on the other. This concept refuses to conceptualise the economy as a closed system in distinction from the social and environmental systems on which it depends.

Raworth also wants to shift the emphasis away from the individual rational chooser of economic theory toward a more social understanding of human flourishing. And in direct contrast to the mainstream paradigm sketched above, in which the market’s job is to deliver economic wealth and the state’s job is to worry about distribution and regulation, Raworth wants an economic system designed from the outset to ensure a more equal distribution and to actively regenerate the environment.

The economic system itself is like an engine that can be put to whatever purpose you want. It generates wealth and wealth can be put to all kinds of uses, good or bad.

How might we evaluate this? Nobody disagrees that financial crises, extreme inequality and environmental damage occur and are bad. A good number of mainstream economists find Raworth’s aims laudable and worth pursuing, because we do need a better measure of success and improved models of human behaviour and ways to incorporate and limit externalities like carbon emissions. Yet they also find her analysis of economics a caricature, as many of the developments in economics over the last few decades seem to be ignored.

For her harshest critics, Raworth fails to give due credit to our current economic system for the incredible reduction in global poverty that it has already enabled, provides very little by way of actionable policy ideas, and is full of erudite but wishful thinking.

Yet the popularity of Doughnut Economics reflects a deep sense amongst many of us (some mainstream economists included) that something is seriously wrong, alongside an instinctive identification with the kind of values and changes that Raworth seeks.

The vital question is: what is our economy for? If we can get a better sense of what purpose we want the economy to serve, it may prove easier to identify whether it is achieving that, or is in some sense ‘broken.’

But to ask this question is immediately to step away from the mainstream paradigm that dominates our public discourse in framing the economy. For mainstream economics, questions of purpose are ethical questions and those questions are explicitly left to the actors within the economic system and the state acting on their behalf. The economic system itself is like an engine that can be put to whatever purpose you want. It generates wealth and wealth can be put to all kinds of uses, good or bad.

These ancient texts suggest that our mainstream paradigm is seriously adrift if it imagines that our economic system is morally neutral.

For many people the idea that the economy itself can be separated from ethical questions will automatically raise an alarm. Certainly, for Christians it ought to. The Bible firmly resists the idea that wealth and its generation is morally neutral. Even the most superficial reading of the Scripture alerts to the inherently spiritual and moral quality of economic activity. Fruitful work is part of what it means to be made in the image of God in the garden of Eden. The product of work is offered to God in worship. The Law is full of commands to deal justly, use fair weights and measures, consider health and safety in the building of a house, and give yourself, your family and your animals a rest (to name but a few). Jesus tells us that you cannot serve both God and money. The pictures of the New Creation in both Old and New Testaments include economic imagery – The Old Testament book of Micah envisions an end to war with everyone living “under their own vine and fig tree” (a vision of peace and economic flourishing) and the New Testament book of Revelation depicts the product of human work being offered up in worship before the throne of God.

Overall the Bible sees the economic, social and environmental dimensions of life as interwoven and interconnected. Take the Sabbath, for instance. It is not only workers who get (or are commanded to take) a Sabbath once a week. The command extends to the whole community - and even to animals. Every seven years, the Sabbath Year provides a rest for the land and for those struggling with debt – the land must be fallow and allowed to regenerate, and all outstanding debts cancelled. Sabbath and Jubilee are deeply intertwined (the Jubilee was effectively a sabbath of sabbaths, taking place after seven sabbath years) and the Jubilee was the theological paradigm chosen by Jesus to explain his own mission and ministry. Quoting the prophet Isaiah, he said:

“The Spirit of the Lord is on me, because he has anointed me to proclaim good news to the poor. He has sent me to proclaim freedom for the captives, recovery of sight for the blind, to set the oppressed free, to proclaim the year of the Lord’s favour.”

These ancient texts suggest that our mainstream paradigm is seriously adrift if it imagines that our economic system is morally neutral. And Raworth is closely aligned with the biblical vision insofar as she insists on the importance of an economy that exists not for its own sake, in some independent sphere, but explicitly to enable people, communities and creation to flourish together. We need to ask what our economy is for. And this is as good an answer as you might find.
