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.

Abundance and the attempt to build a better world

Is this policy the antidote to the zero-sum game of politics?

What do you do when more money won’t solve a government’s problems? Abundance: How We Build A Better Future, the new book by Ezra Klein and Derek Thompson is an extended polemic against a form of government—particularly as practiced by US liberals—that stymies policy delivery. However technocratic that sounds (and the book often is), it forces readers to confront deeper questions about the nature of politics.  

At the heart of the book is a critique of what the authors, drawing on the film Everything Everywhere All At Once, call 'Everything Bagel Liberalism'. In the film topping are added to bagel to the point that it becomes a blackhole. So too, Klein and Thompson suggest, with so much well-intended policy, in which in seeking to tick every possible box and satisfy a range of regulators it becomes a delivery blackhole and little is actually done. The authors ask whether parties of the left are focused on measuring spending to the exclusion of measuring what gets built.  

The first chapter gives a good sense of their approach.  It tells a familiar story about the way in which so many are being priced out of cities because of a lack of affordable housing. However, in doing so, it highlights a surprising harm: that geographical proximity remains an important enabler of technological innovation so a lack of affordable housing in cities means a loss of creativity. 

The diagnosis is perhaps even more surprising coming from American liberals. Special interests—including those seeking to protect the value of their own houses—weaponize interlocking sets of well-intentioned legislation to prevent homes being built. Subsequent chapters apply that similar logic—regulation and a lack of focus resulting in inaction—to infrastructure, government capacity, scientific research and the implementation of new inventions. 

The book's strength is that it is not particularly detailed in its policy proposals. Klein and Thompson instead offer abundance as a lens through which policy development can be viewed: what do we need more of and how do we get it? This lens can be applied from within a wide range of ideological frameworks. It is not itself a worldview but a challenge that any politics should be obsessed with effective delivery not simply desiring the correct end-state.  

The book is unapologetically focused on America and the failures of progressive governance, particularly in California. (One of this book's peculiar legacies will be to leave many who have never been there perpetually invested in California's struggles to build high-speed rail.) Nevertheless, the approach already has its advocates in the UK - for example, the Centre for British Progress which set out its stall last week, and it is not hard to see how an agenda here that could be seized by a less hesitant Starmer government.  

Any plausible political analysis must hold together the reality of scarcity and abundance. Losing sight of either unmoors us from the actual world we find ourselves in.

Indeed, perhaps the book might feel more realistic if it had other countries in mind. Reviewing Abundance, Columbia economist Adam Tooze describes the book as painful to read, characterising it as a manifesto for the Harris presidency that never was. Indeed, according to the authors, the book was originally scheduled for release in summer 2024 to influence the Democratic platform leading up to the 2024 elections. Instead, it appears in 2025 amid Trump's assault on institutions, Tooze's Columbia among them.  

In an interview on Pod Save America, the authors argued that the book is still relevant, offering a framework with which Democrats can oppose Trump. Thompson described the Trumpian view of politics as fundamentally shaped by scarcity. He suggests that behind 47th president's policies—most notably the tariff agenda—is the conviction that every interaction is zero-sum; for you to gain, I must lose.  On this analysis, the way to oppose a politics that pits groups against one another over limited resources—housing, trade, jobs—is to figure out how the government can provide more and argue for it. In its critique and its hopefulness, Abundance offers those who believe in institutions a way to navigate—even work with the grain of—the anti-institutional temperament of contemporary politics.  

There might be something to this messaging, but scarcity plays an unmissable role in Klein and Thompson's argument. Remember that they characterise what they oppose as "Everything Bagel Liberalism", policy that tries to achieve every outcome and loses focus in doing so. They may conceive scarcity differently to Trump, but their book is a warning policy cannot deliver as much as we think. It is a call for us to oppose, to compete against those special interests—whether they be residents’ associations wanting to hold up house prices or politicians wanting to cut research grants—whose policy priorities overload the bagel.  

At heart, the book is a reminder that ultimately the salient scarcity in politics is not housing or trade or even money. It is time. Abundance cautions governments that unfocussed policy yields the time entrusted to them by the governed.  

Humans cannot lead politics completely beyond its zero-sum logic. The world is so often a violent competition over resources and government must restrain that violence while avoiding being co-opted as a means of exploitation.  And yet, politics is also—even primarily—an avenue through which communities answer a primal summons to be fruitful, abundant.  

Ultimately, any plausible political analysis must hold together the reality of scarcity and abundance. Losing sight of either unmoors us from the actual world we find ourselves in. Yes, there is so much broken and warped to reckon with, and we must grapple too with our finitude’s bluntness, but so too is creation replete with goodness, among them our capacity to invent and deliver what we need together.
