In 1984, George Orwell told the story of Winston Smith, an employee in the propaganda office of a totalitarian regime. Smith's job at the fictional Ministry of Truth was to destroy photographs and alter documents, remaking the past to fit the needs of the present. But 1984 came and went, along with Soviet communism. In the age of the Internet, nobody could tamper with the past that way. Could they?
Yes, we can. In fact, last week, Slate did.
We took the Ministry of Truth as our model. Here's how Orwell described its work:
As soon as all the corrections which happened to be necessary in any particular number of The Times had been assembled and collated, that number would be reprinted, the original copy destroyed, and the corrected copy placed on the files in its stead. This process of continuous alteration was applied not only to newspapers, but to books, periodicals, pamphlets, posters, leaflets, films, sound-tracks, cartoons, photographs—to every kind of literature or documentation which might conceivably hold any political or ideological significance. Day by day and almost minute by minute the past was brought up to date. In this way every prediction made by the Party could be shown by documentary evidence to have been correct, nor was any item of news, or any expression of opinion, which conflicted with the needs of the moment, ever allowed to remain on record. All history was a palimpsest, scraped clean and reinscribed exactly as often as was necessary. In no case would it have been possible, once the deed was done, to prove that any falsification had taken place.
Slate can't erase all records the way Orwell's ministry did. But with digital technology, we can doctor photographs more effectively than ever. And that's what we did in last week's experiment. We altered four images from recent political history, took a fifth out of context, and mixed them with three unadulterated scenes. We wanted to test the power of photographic editing to warp people's memories.
We aren't the first to try Orwell's idea on real people. Elizabeth Loftus, an experimental psychologist, has been tampering with memories in her laboratory for nearly 40 years. Photo doctoring is just one of many techniques she has tested. In an experiment published three years ago, she and two colleagues demonstrated that altered images of political protests in Italy and China influenced Italian students' descriptions of those incidents. We wanted to see whether similar tampering could work in the United States.

Forty years ago, when Loftus came out of graduate school, most people thought of memory as a recording device. It stored imprints of what you had experienced, and you could retrieve these imprints when prompted by questions or images. Loftus began to show that this wasn't true. Questions and images didn't just retrieve memories. They altered them. In fact, they could create memories that were completely unreal.
Most of the time, this didn't matter. If Uncle Pete hadn't really caught that 18-inch trout, so what? But in court, it mattered. Men were going to jail based on contaminated eyewitness testimony. Families were being ruined by charges of incestuous abuse drawn from memories concocted in therapy.
Loftus set out to prove that such memories could have been planted. To do so, she had to replicate the process. She had to make people remember, as sincerely and convincingly as any sworn witness, things that had never happened. And she succeeded. Her experiments shattered the legal system's credulity. Thanks to her ingenuity and persistence, the witch hunts of the recovered-memory era subsided.
But the experiments didn't stop. Loftus and her collaborators had become experts at planting memories. Couldn't they do something good with that power? So they began to practice deception for real. With a simple autobiographical tweak—altering people's recollections of childhood eating experiences—they embarked on a new project: making the world healthier and happier.
It was almost a kind of forgetting. You start doing something to show how dangerous it is. Pretty soon, you're good at it. It becomes your craft, your identity. You begin to invent new applications and justifications for it. In changing others, you change yourself.
To understand Elizabeth Loftus, I spent many hours reading her work and talking with her. I came away impressed by her thoughtfulness and curiosity. I was shaken, as others have been, by her research on memory's fallibility. But I was struck even more by Loftus herself. Something has happened to her. She is grappling with something nobody has fully confronted before: the temptation of memory engineering.
This is the story of a woman who has learned how to alter the past as we know it. It's a fantastic power: exciting to some, frightening to others. What will we do with it? How will it change us? In her story, we can begin to see what awaits us.
