The first adjustment was minor. It involved a script, a comedy about a family that lived in a house on a street that did not exist in any city that existed. The writer, a man named Danny who was twenty-six and had never lived on a street that existed for more than a year, had placed the house at 742 Evergreen Terrace, which was an address that existed on a television show that had been running for three years. It was a joke. Danny had written the address as a joke. The producer, a man named Rick who was forty-one and had been producing television for fifteen years, noticed the address and said it reminded him of someone he knew who lived on a street with a similar name. Rick asked Danny to change it to 744 Evergreen Terrace, a number that did not exist on the television show. Danny changed it. It took ten seconds. It did not matter.

The second adjustment involved a scene. Danny had written a scene in which a character worked for a company called Sky Mirror Entertainment. The company name was fictional. It had been chosen because it sounded like something a real company might be called, which was the point of fictional company names. Rick said that there was a real company called Sky Mirror Corporation that did satellite work, that the similarity might cause confusion, that Danny should change it to Sky Array Entertainment. Danny changed it. It took fifteen seconds. It did not matter.

The third adjustment involved a plot point. Danny had written a scene in which the Sky Mirror company's equipment malfunctioned and pointed all of its satellites at the North Pole. Rick said that the plot point sounded unrealistic, that satellites could not be pointed at a single geographic coordinate in the way Danny described, that it would be more believable if the equipment pointed at a weather system instead. Danny rewrote the scene. It took two hours. He thought about it the next day, briefly, wondering if pointing at a weather system was actually more realistic or just different, but decided that it did not matter because the scene worked either way.

The fourth adjustment involved a character. Danny had written a character named Theodore Vanderbilt, a wealthy businessman who invented the equipment and was responsible for the malfunction. Rick said that Vanderbilt was the name of a real family, that there might be descendants of that family who would be offended by a character who was responsible for a disaster, that it would be better to change the name to Theodore VanDyke. Danny changed it. It took ten seconds. He thought about why a name change was necessary but did not object, because Rick was the producer and Rick was paying him and the name VanDyke sounded similar enough to Vanderbilt that the change was barely noticeable.

The fifth adjustment involved the consequences of the malfunction. Danny had written the malfunction as a disaster. Satellites pointed at the North Pole caused ice to melt. Ice melting caused water to rise. Water rising flooded cities. People lost homes. Rick said that the disaster sequence was too dark for a comedy, that it would be better if the malfunction caused something less destructive, something that affected the character personally rather than the entire planet. Danny rewrote the sequence. The malfunction no longer caused a global disaster. It caused Theodore to lose his company, his fortune, and his reputation. People did not drown. Theodore himself did not die. He lost everything and then worked for ten years to rebuild something small and unimportant. Danny thought about this change for several days. He considered writing an email to Rick objecting to the tonal shift, but did not, because Rick was right that it was a comedy and the original disaster sequence was very dark.

The sixth adjustment involved the ending. Danny had written an ending in which Theodore died in an accident while trying to correct the malfunction. Rick said that the death was unnecessary, that Theodore losing everything was punishment enough, that the audience would not want to see him die. Danny removed the death. It took thirty seconds. He replaced it with a scene in which Theodore sat alone in a small apartment, watching the news, seeing that the ice had melted anyway, that the water had risen anyway, that his personal punishment did not match the scale of the damage he had caused. Rick said this was too ambiguous for a comedy ending. Danny changed it. Theodore sat alone and then received a phone call offering him a new job at a small company. The phone call was the end.

The seventh adjustment was the final one. The script was finished. It had been through twelve drafts. Each draft had contained one adjustment, each adjustment reasonable in isolation, each adjustment made by a man who believed that he was being professional, that he was accommodating feedback, that he was collaborating with the people who paid him. The final script was a comedy about a man named Theodore VanDyke who worked for a company called Sky Array Entertainment, whose equipment malfunctioned and pointed at a weather system instead of a geographic coordinate, causing him to lose his company and his fortune but not causing a global disaster, and who ended the story by receiving a phone call offering him a new job.

Danny was paid for the final draft. He received a check for an amount of money that was larger than anything he had ever received for a script. He deposited the check. He paid his rent. He ate dinner at a restaurant in West Hollywood. He did not think about the script again.

The producer, Rick, was promoted six months later. The show had been a ratings success, and Rick's ability to keep scripts on time and on budget had been noted by the network executives who decided promotions. They did not read the scripts. They read the budgets. Rick's budgets were always on time and on budget. He had a system for making adjustments efficiently, for processing feedback without slowing production down, for keeping the creative process moving forward without stopping to reconsider decisions that had already been made. He wrote a brief memo about it, four pages long, that was distributed at a management seminar. It did not mention the mirror show. It did not mention Danny.

Danny's agent called him a week later, excited about a new opportunity. A feature film, a big studio project, a director who had just won an award. The script was in development, and the agent said there might be room for a rewrite, that Danny might be interested. Danny was interested. He asked about the script, about the story, about what needed rewriting. The agent said she would send the materials. The materials came two days later, a stack of pages that Danny read in his apartment, sitting at a table that he used for no other purpose than reading scripts, because reading a script was an activity that required attention and his apartment had no room where he could sit and pay attention to anything that was not a television. The script was about a man who built a system to help people and the system malfunctioned and caused harm. Danny read it. He recognized elements of his own work in it, the mirror company, the North Pole, the wealthy inventor. He was not the credited writer. He had never heard of the previous writers. He sent the agent an email saying he was interested. He thought about the mirror comedy he had written and revised and revised again until it was unrecognizable. He thought about the real mirrors, the real mirrors in space, and whether anyone who had worked on the mirror project had ever felt the way he felt reading that new script, the way of looking at a story and seeing your own history reflected in it but changed, changed in small ways, changed in ways that seemed reasonable at the time. He did not mention this to his agent. Agents did not want to hear about this. Agents wanted to know if the writer could deliver.

Years later, he heard about a real company that had built equipment that pointed at the North Pole. He heard about ice melting. He heard about water rising. He heard about people losing their homes. He turned on the television and watched a comedy about a man who had caused all of this and lost everything and received a phone call at the end. He did not recognize his own name in the credits. He did not think about it. He changed the channel.

Each adjustment had been reasonable. Each adjustment had been small. None of them, individually, changed the fundamental nature of the work. But together, they had changed everything, because the threshold was not crossed in a single step but in seven small steps, each one below the threshold of objection, each one below the threshold of awareness, each one reasonable in isolation and unreasonable in aggregate. The danger was not in any single adjustment. The danger was in the sequence, in the way that each adjustment made the next adjustment easier, in the way that the man making the adjustments believed he was in control of the process when the process was controlling him, when the process was changing both the script and the man who was writing it, changing him in small steps, each one reasonable, each one below the threshold of awareness, until the man looked in the mirror of his own work and did not recognize what he saw.
