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.

From Nigeria’s killing fields to Europe’s shores, the data behind the domino effect

While Nigeria thrives, some left-behind are desperate to escape.

Chris Wadibia is an academic advising on faith-based challenges. His research includes political Pentecostalism, global Christianity, and development.

Just as every coin has two sides, every soul contains the equal capacity for good and evil. Just like affairs of the soul, migration has the ability to strengthen or weaken societies.  

Nigeria, the Giant of Africa, has one of the world’s largest and most professionally distinguished diasporas. Over 17 million Nigerians live in other countries. The most famous members of the Nigerian diaspora, figures like Ngozi Okonjo-Iweala, Chimamanda Ngozi Adichie, Anthony Joshua, John Boyega, Giannis Antetokounmpo, and Wally Adeyemo, have achieved stardom thanks to talents that impact or entertain millions of people globally.  

However, these famous figures merely represent the glorious one percent of the Nigerian diaspora. Their success can easily distract observers from the grim reality of why so many Nigerians desperately seek to leave a country known for producing world changers.  

Seeking data on violence 

In October 2019, researchers at the Observatory of Religious Freedom in Africa started a project exploring the nature and impacts of of religious violence in Nigeria. The project spanned four years and generated many significant findings. Terror groups in Nigeria killed 31,000 civilians in 7,000 attacks in just four years, the Fulani Ethnic Militia (FEM) accounting for 39 per cent of these killings (a figure dwarfing the killings perpetrated by ISIS and al-Qaeda affiliates),  So called “land-based community attacks,” a concept referring to instances when actors like FEM invade small Christian farming settlements to kill, rape, and abduct Christians and burn their homes, accounted for 82 per cent of civilian killings in the study, Christian death tolls far exceeding Muslim death tolls (2.7 Christians killed for every 1 Muslim killed) in the reporting period, and 6.5 times as many Christian murders compared to Muslim murders relative to average state populations.  

The methodology of the study set out to find data on all the people, regardless of their religion, negatively affected by terrorist violence. However, with every new batch of data collected, disturbing patterns emerged. Since the 2009 birth of the infamous Boko Haram insurgency, global media coverage of the terrorist violence has consistently argued Muslims rather than Christians disproportionately bear the brunt of this Islamist extremist violence. The findings of the study suggest otherwise.

Shouldn’t the government do something? 

Historically, Nigerian governments have been reticent, even reluctant, to condemn violence in the north associated with the Fulani ethnic group. Former presidents like Muhammadu Buhari, a member of the Fulani, have even gone as far as to dismiss the issue of Fulani ethnic violence as just “cattle rustling.” However, in Nigeria, mere “cattle rustling” to some is a seriously grave situation for others.  

Findings by the Observatory researchers suggest Nigerian security operatives, most of whom belong to the Fulani and Hausa ethnic groups, have a suspiciously selective way of engaging with terrorist violence in northern Nigeria, often leaving Christians distinctively vulnerable. Roman Catholics in Nigeria have even accused Nigeria's military of being a jihadist force. Churches in northern Nigeria live in a constant state of terror and acutely distressing fear.  

In Nigeria, the federal government alone, led by the president, has the final say on matters concerning security and the army. Incumbent President Bola Ahmed Tinubu has notably appointed far more Christians to senior government offices than his predecessor, Buhari. The Nigerian government is famously opaque. Despite its nominally democratic visage, family dynasties and networks continue to dominate political life and business affairs.  

Understanding the religious geography and reaction 

Religion in Nigeria is divided along geographical lines. The northern half is dominated by conservative Islam. Catholicism and Anglicanism reign supreme in the southeast. The southwest functions as a geographical melting pot of Islam (albeit a more secular variety compared to the north) and Christianity (especially Pentecostalism).  The north contains a surprisingly large number of Pentecostals. Many Pentecostal pastors and choirs in the north have been kidnapped by the mercilessly violent Islamist extremists.  

The overwhelming majority of Christians in Nigeria live in the southern half of the country. However, in a Nigeria which has suffered from one oppressive government after another for decades (most of these led by conservative Islamic military and civilian presidents), most Christians struggle to survive and lack the energy to speak up for their northern kin. Despite their weariness, the Southern Nigerian Church (the collective population of Christians living in the south) has a sacred responsibility to awaken and demand greater protections from the federal government and the military for Christians living in the north.   

Local causes, global effect 

Over the last two decades, commentators have routinely pointed to climate change as the primary factor facilitating violent encounters between Muslims and Christians. Fulani cattle herders, guided by the desire for better grazing lands for their livestock, have often encroached on land owned by Christian farmers in the north and middle regions. The findings by researchers at the Observatory suggest significantly more is going on to facilitate these violent clashes than just climate change. Ascribing the challenge of religious violence in Nigeria to just climate change provides a get-out-of-jail free card to the men of violence linked to the orchestrated killings of Christians. 

Ethno-religious violence has quietly become commonplace in northern Nigerian life. The single solution capable of curbing this violence is unprecedented, cross-party, interethnic, and interreligious security reform. Strength of security affects every person in Nigeria. From the richest to the poorest, no one is immune from a sudden kidnapping, suicide bomb, or violent act of banditry negatively changing their life forever.  

Nigeria's neighbours in Europe cannot afford to continue slumbering and must wake up. Readers in Europe feeling insulated from the violence the data records are just as susceptible to the shockwaves that a collapse of the Nigerian state as other West African neighbours. Such an event would imperil the security of citizens in countries like Italy, Spain, and Greece just as much as it would people living in Mali, Chad, and Cameroon.  

Nigeria has never been nearer to a civil war or state collapse since the Biafra War of the late 1960s. Ethno-religious violence disproportionately targeting northern Christians is one of the greatest and most overlooked factors contributing to Nigeria's dysfunctionality. In an unprecedentedly connected world, such a collapse would, in turn, trigger further collapses.  The European Union (EU) does not grasp the severity of how such a collapse would affect its own security and stability. At a time when every day brings news of small boats carrying migrants to European shores, Nigeria's collapse would trigger one of the greatest avalanches of mass migration in modern African history.  

A modern Middle Passage 

Nigeria has a population of over 235 million, the largest in Africa and sixth largest globally. If just 10 per cent of the population attempted to flee in the event of another civil war or a destabilising political event, that is 23 million Nigerians desperately fleeing into any country they reason might welcome them. Many of these millions would gamble by voyaging on the tempestuous Atlantic Ocean in small boats with the goal of beginning new lives in European countries. Some would inevitably perish in what might evolve into this century's Middle Passage. Nigeria’s collapse would destroy the EU by overwhelming its borders and social services. The average population of an EU country is just under 17 million, or the size of Nigeria's diaspora. The unprecedented connectedness of our world means catastrophic destabilisation in one country can have significant consequences for the stability of other countries globally. The EU has a geopolitical responsibility to invest in improving Nigeria's security situation. Abductions, killings, and displacements in Nigeria might trigger instability in Europe and beyond. 

However, the collapse of Nigeria would not only destabilise the EU. ISIS affiliates like ISWAP (Islamic State West Africa Province) have a strategic interest in Nigeria's collapse, because it would open the door for them to expand their control throughout West Africa.  

A team of researchers guided by the goal of better understanding terrorist violence in Nigeria simply followed the breadcrumbs of organically emergent data to show why the broader world should take seriously violence against Christians in the Giant of Africa. Living in an unprecedentedly connected world comes with new privileges and new responsibilities. To simply indulge in these new privileges without standing strong and shouldering these new responsibilities would be foolish, selfish, and nearsighted.  

English poet John Donne once famously wrote,

No man is an island,  
Entire of itself,  of the continent,  
A part of the main.  
If a clod be washed away by the sea,  
Europe is the less. 
Every man is a piece.

The “old self” understanding of global connectedness, ruled by selfishness and ignorance, must give way to the “new self” model of prosperity and security via proactive collaboration. For every one Okonjo-Iweala, Boyega, or Antetokounmpo, millions of Nigerians suffering from the effects of a rapidly destabilising state dream of emigrating abroad. Global Christianity and global security stakeholders each have an interest in a stable Nigeria. A stable Nigeria functions as a wellspring of human capital for the benefit of the entire world.  

Donne, in the same poem, wrote,  

Each man's death diminishes me, 
For I am involved in mankind. 
Therefore, send not to know 
For whom the bell tolls, 
It tolls for thee. 

The world is involved in Nigeria and Nigeria is involved in the world. The death of Nigeria would pave the way for the death of the EU. The bell tolls for the EU community to awaken from decades of neglectfully overlooking its interests in a stable and secure Nigeria.
