the guardian: 'The story of the self'
Our ability to remember forms the basis of who we are and is a psychological trick that fascinates cognitive scientists. But how reliable are our memories?

Memory is our past and future. To know who you are as a person, you need to have some idea of who you have been. And, for better or worse, your remembered life story is a pretty good guide to what you will do tomorrow. "Our memory is our coherence," wrote the surrealist Spanish-born film-maker, Luis Buñuel, "our reason, our feeling, even our action." Lose your memory and you lose a basic connection with who you are.
It's no surprise, then, that there is fascination with this quintessentially human ability. When I cast back to an event from my past – let's say the first time I ever swam backstroke unaided in the sea – I don't just conjure up dates and times and places (what psychologists call "semantic memory"). I do much more than that. I am somehow able to reconstruct the moment in some of its sensory detail, and relive it, as it were, from the inside. I am back there, amid the sights and sounds and seaside smells. I become a time traveller who can return to the present as soon as the demands of "now" intervene.
This is quite a trick, psychologically speaking, and it has made cognitive scientists determined to find out how it is done. The sort of memory I have described is known as "autobiographical memory", because it is about the narrative we make from the happenings of our own lives. It is distinguished from semantic memory, which is memory for facts, and other kinds of implicit long-term memory, such as your memory for complex actions such as riding a bike or playing a saxophone.
When you ask people about their memories, they often talk as though they were material possessions, enduring representations of the past to be carefully guarded and deeply cherished. But this view of memory is quite wrong. Memories are not filed away in the brain like so many video cassettes, to be slotted in and played when it's time to recall the past. Sci-fi and fantasy fictions might try to persuade us otherwise, but memories are not discrete entities that can be taken out of one person's head, Dumbledore-style, and distilled for someone else's viewing. They are mental reconstructions, nifty multimedia collages of how things were, that are shaped by how things are now. Autobiographical memories are stitched together as and when they are needed from information stored in many different neural systems. That makes them curiously susceptible to distortion, and often not nearly as reliable as we would like.
We know this from many different sources of evidence. Psychologists have conducted studies on eyewitness testimony, for example, showing how easy it is to change someone's memories by asking misleading questions. If the experimental conditions are set up correctly, it turns out to be rather simple to give people memories for events that never actually happened. These recollections can often be very vivid, as in the case of a study by Kim Wade at the University of Warwick. She colluded with the parents of her student participants to get photos from the undergraduates' childhoods, and to ascertain whether certain events, such as a ride in a hot-air balloon, had ever happened. She then doctored some of the images to show the participant's childhood face in one of these never-experienced contexts, such as the basket of a hot-air balloon in flight. Two weeks after they were shown the pictures, about half of the participants "remembered" the childhood balloon ride, producing some strikingly vivid descriptions, and many showed surprise when they heard that the event had never occurred. In the realms of memory, the fact that it is vivid doesn't guarantee that it really happened.
Even highly emotional memories are susceptible to distortion. The term "flashbulb memory" describes those exceptionally vivid memories of momentous events that seem burned in by the fierce emotions they invoke. In the aftermath of the terrorist attacks of 9/11, a consortium of researchers mobilised to gather people's stories about how they heard the news. When followed up three years later, almost half of the testimonies had changed in at least one key detail. For example, people would remember hearing the news from the TV, when actually they initially told the researchers that they had heard it through word of mouth.
What accounts for this unreliability? One factor must be that remembering is always re-remembering. If I think back to how I heard the awful news about 9/11 (climbing out of a swimming pool in Spain), I know that I am not remembering the event so much as my last act of remembering it. Like a game of Chinese whispers, any small error is likely to be propagated along the chain of remembering. The sensory impressions that I took from the event are likely to be stored quite accurately. It is the assembly – the resulting edit – that might not bear much resemblance to how things actually were.
When we look at how memories are constructed by the brain, the unreliability of memory makes perfect sense. In storyboarding an autobiographical memory, the brain combines fragments of sensory memory with a more abstract knowledge about events, and reassembles them according to the demands of the present. The memory researcher Martin Conway has described how two forces go head to head in remembering. The force of correspondence tries to keep memory true to what actually happened, while the force of coherence ensures that the emerging story fits in with the needs of the self, which often involves portraying the ego in the best possible light.
One of the most interesting writers on memory, Virginia Woolf, shows this process in action. In her autobiographical essay, A Sketch of the Past, she tells us that one of her earliest memories is of the pattern of flowers on her mother's dress, seen close-up as she rested on her lap during a train journey to St Ives. She initially links the memory to the outward journey to Cornwall, noting that it is convenient to do so because it points to what was actually her earliest memory: lying in bed in her St Ives nursery listening to the sound of the sea. But Woolf also acknowledges an inconvenient fact. The quality of the light in the carriage suggests that it is evening, making it more likely that the event happened on the journey back from St Ives to London. The force of correspondence makes her want to stick to the facts; the force of coherence wants to tell a good story.
How many more of our memories are a story to suit the self? There can be no doubt that our current emotions and beliefs shape the memories that we create. It is hard to remember the political beliefs of our pasts, for example, when so much has changed in the world and in ourselves. How many of us can accurately recall the euphoria at Tony Blair's election in 1997? When our present-day emotions change, so do our memories. Julian Barnes describes this beautifully in his Booker-winning The Sense of an Ending, when a shift in his protagonist Tony's feelings towards his former lover's parents unlocks new memories of their relationship. "But what if, even at a late stage, your emotions relating to those long-ago events and people change? … I don't know if there's a scientific explanation for this … All I can say is that it happened, and that it astonished me."
Of all the memories we cherish, those from childhood are possibly the most special. Few of us will have reliable memories from before three or four years of age, and recollections from before that time need to be treated with scepticism. When you think about the special cognitive tricks involved in autobiographical memory, it's perhaps no surprise that it takes a while for children to start doing it right. Many factors seem to be critical in children's emergence from childhood amnesia, including language and narrative abilities. When we are able to encode our experience in words, it becomes much easier to put it together into a memory. Intriguingly, though, the boundary of childhood amnesia shifts as you get closer to it. As a couple of recent studies have shown, if you ask children about what they remember from infancy, they remember quite a bit further back than they are likely to do as adults.
There are implications to the unreliability of childhood memories. A recent report commissioned by the British Psychological Society warned professionals working in the legal system not to accept early memories (dating from before the age of three) without corroborating evidence. One particular difficulty with early memories is their susceptibility to contamination by visual images, such as photographs and video. I'm sure that several of my childhood memories are actually memories of seeing myself in photos. When we look back into the past, we are always doing so through a prism of intervening selves. That makes it all the more important for psychologists studying memory to look for confirming evidence when asking people to recall their pasts.
And yet these untrustworthy memories are among the most cherished we have. Memories of childhood are often made out to have a particular kind of authenticity; we think they must be pure because we were cognitively so simple back then. We don't associate the slipperiness of memory with the guilelessness of youth. When you read descriptions of people's very early memories, you see that they often function as myths of creation. Your first memory is special because it represents the point when you started being who you are. In Woolf's case, that moment in her bed in the St Ives nursery was the moment she became a conscious being. "If life has a base that it stands upon," she wrote, "if it is a bowl that one fills and fills and fills – then my bowl without a doubt stands upon this memory."
What should we do about this troublesome mental function? For one thing, I don't think we should stop valuing it. Memory can lead us astray, but then it is a machine with many moving parts, and consequently many things that can go awry. Perhaps even that is the wrong way of looking at it. The great pioneer of memory research, Daniel Schacter, has argued that, even when it is failing, memory is doing exactly the thing it is supposed to do. And that purpose is as much about looking into the future as it is about looking into the past. There is only a limited evolutionary advantage in being able to reminisce about what happened to you, but there is a huge payoff in being able to use that information to work out what is going to happen next. Similar neural systems seem to underpin past-related and future-related thinking. Memory is endlessly creative, and at one level it functions just as imagination does.
That's how I think we should value memory: as a means for endlessly rewriting the self. It's important not to push the analogy with storytelling too far, but it's a valuable one. Writing about her novel, Wolf Hall, Hilary Mantel has explained how she brought the protagonist Thomas Cromwell alive for the reader by giving him vivid memories. When writers create imaginary memories for their characters, they do a similar kind of thing to what we all do when we make a memory. They weave together bits of their own personal experience, emotions and sensory impressions and the minutiae of specific contexts, and tailor them into a story by hanging them on to a framework of historical fact. They do all that while making them fit the needs of the narrative, serving the story as much as they serve truth.
To emphasise its narrative nature is not to undermine memory's value. It is simply to be realistic about this everyday psychological miracle. If we can be more honest about memory's quirks, we can get along with it better. When I think back to my first attempt at solo swimming, it doesn't bother me that I have probably got some of the details wrong. It might be a fiction, but it's my fiction, and I treasure it. Memory is like that. It makes storytellers of us all.

Jonathan Jones: the meaning of 9/11's most controversial photo
Relatively an old article, but I keep on referring to Jonathan Jones's vast knowledge that he uses in the right moments, and most importantly his generosity in the criticism field.
The meaning of 9/11's most controversial photo
Thomas Hoepker's photo of New Yorkers apparently relaxing as the twin towers smoulder says much about history and memory
• See here for Framing the debate on the death of Gaddafi
In the photograph Thomas Hoepker took on 11 September 2001, a group of New Yorkers sit chatting in the sun in a park in Brooklyn. Behind them, across brilliant blue water, in an azure sky, a terrible cloud of smoke and dust rises above lower Manhattan from the place where two towers were struck by hijacked airliners this same morning and have collapsed, killing, by fire, smoke, falling or jumping or crushing and tearing and fragmentation in the buildings' final fall, nearly 3,000 people.
Ten years on, this is becoming one of the iconic photographs of 9/11, yet its history is strange and tortuous. Hoepker, a senior figure in the renowned Magnum photographers' co-operative, chose not to publish it in 2001 and to exclude it from a book of Magnum pictures of that horribly unequalled day. Only in 2006, on the fifth anniversary of the attacks, did it appear in a book, and then it caused instant controversy. The critic and columnist Frank Rich wrote about it in the New York Times. He saw in this undeniably troubling picture an allegory of America's failure to learn any deep lessons from that tragic day, to change or reform as a nation: "The young people in Mr Hoepker's photo aren't necessarily callous. They're just American."
In other words, a country that believes in moving on they have already moved on, enjoying the sun in spite of the scene of mass carnage that scars the fine day. Indeed, I can't help thinking the five apparently unmoved New Yorkers resemble the characters in the famous 1990s television comedy Seinfeld, who in the show's final episode are convicted under a Good Samaritan law of failing to care about others.
Rich's view of the picture was instantly disputed. Walter Sipser, identifying himself as the guy in shades at the right of the picture, said he and his girlfriend, apparently sunbathing on a wall, were in fact "in a profound state of shock and disbelief". Hoepker, they both complained, had photographed them without permission in a way that misrepresented their feelings and behaviour.
Well, you can't photograph a feeling. But another five years on since it surfaced in 2006, it seems pointless to argue about the morality of the people in the picture, or of the photographer, or his decision to withhold the picture from publication. It is now established as one of the defining photographs of that day – with the 10th anniversary of the World Trade Centre's destruction approaching, the Observer Review republished it this August as the 9/11 photograph.
It is the only photograph of that day to assert the art of the photographer: among hundreds of devastating pictures, by amateurs as well as professionals, that horrify and transfix us because they record the details of a crime that outstripped imagination – even Osama bin Laden dared not expect such a result – this one stands out as a more ironic, distanced, and therefore artful, image. Perhaps the real reason Hoepker sat on it at the time was because it would be egotistical to assert his own cunning as an artist in the midst of mass slaughter.
Today, the meaning of this photograph has nothing to do with judging individuals. It has become a picture about history, and about memory. As an image of a cataclysmic historical moment it captures something that is true of all historical moments: life does not stop dead because a battle or an act of terror is happening nearby. Artists and writers have told this truth down the ages. In his painting The Fall of Icarus, the Renaissance painter Pieter Bruegel depicts a peasant ploughing on as a boy falls to his death in the sea beyond: it is a very similar observation to Hoepker's. WH Auden's lines on this painting in his poem Musée des Beaux Arts apply perfectly to the photograph: "In Breughel's Icarus, for instance: how everything turns away / Quite leisurely from the disaster …"
Stendhal similarly captures the dissonance of history in his novel The Charterhouse of Parma. A young man volunteers to fight for Napoleon at Waterloo, but instead of a defining moment of courage all he experiences are random, marginal, meaningless accidents on the edges of the great day.
History is not a heroic story, nor memory a block of marble inscribed with imperishable words of grief and rage. As Tony Blair – whose own response to this act of inhuman cruelty was to have such historic consequences – says of that day in his book A Journey, "It is amazing how quickly shock is absorbed and the natural rhythm of the human spirit reasserts itself … We remember, but not as we felt at that moment."
Personally I remember the shock of that moment perfectly. I have nightmares about it, which is strange, considering I am not an American and witnessed it only on television in Hackney, London. But I had come to love New York deeply and it felt like – it was – an attack on everything I held dear. Yet arguments about the meaning and, urgently, the response to this colossal act of violence started immediately. For every horrific account you can read of that day a horror has been caused, either directly or indirectly, by the "war on terror" that resulted: 12,000 killed by suicide bombers in Iraq …
And so, 10 years on, the meaning of this photograph is that memories fade fast. The people in the foreground are us. We are the ones whose lives went on, touched yet untouched, separated from the heart of the tragedy by the blue water of time, which has got ever wider and more impossible to cross. A 10-year-old event belongs to history, not the present. To feel the full sorrow of it now you need to watch a documentary – and then you will switch to something lighter, either because it is painfully clear that too much blood has been spent around the world in the name of this disaster, or simply because changing channels is what humans do. The people in this photograph cannot help being alive, and showing it.
