A loop that can be named can be starved. Most of what gets called personality, relapse, or “I don’t know why I did that” is not a mystery. It is a habit with a paycheck. A tone in a doorway. A phone on a pillow. A yes in two seconds. The body fires. The world pays. The ritual gets cheaper. The Data Exorcism is a stealth ABA field manual for making that machinery visible — then changing its diet. It is not a clinic script. It is not a token board. It is not a program you run on someone who did not agree. Applied Behavior Analysis is treated here as a science of how environments select behavior, used with dignity, and aimed first at your own Tuesday. The work has three moves, in order. Isolate. Stop guessing. Run a seven-day census on one loop. Write what happened in camera language — what a stranger could see — not the story you tell yourself after. Learn the three clocks (body, clock, calendar). Sort trigger classes. Read a week of cards until the payoff is obvious. Starve. Stop feeding the static without starving the need. Extinction is not punishment and it is not a personality makeover. Plan the burst. Route the same need through a cheaper, cleaner act. Thin the ritual. Do not hunt the person. Break. Starving is not enough if the old sentence is still running the room. Use SLOW when the room goes red. Titrate. Install a competing loop. Disconfirm the sentence with evidence, not slogans. Stop when the tool is the wrong religion. Inside: worked cases (the kitchen tone, the eleven-o’clock scroll, the child and the blender, fawn at work), a catalog of common loops, scripts you can actually say, thirty- and ninety-day arcs, worksheets, and a hard ethics chapter — including when to put the book down. Read it if insight has not changed your Tuesday. Read it if you want the laws of behavior without the assembly line. Starve only what should not be fed. Break nothing that is trying to keep someone alive.
