How do I live with the risk that my model gets someone's life wrong?
You build things that decide about people — their money, their freedom, their health. You know the model will be wrong sometimes. You do not know when, or about whom. That knowledge sits on your chest at night. Here is what you must see clearly: the sleeplessness proves nothing. It does not make the model safer. It does not undo an error already made. It is only weight, and weight left to sit does no work. What matters is not how heavy you feel — it is what checks exist before the model ever touches a real person. If this weight has gone past worry — if it is costing you sleep or food for weeks, not nights — that is worth saying out loud to a doctor or counselor, not carrying alone.
The weight is not the problem. It is the correct response to real power over real lives. Do not try to make it go away — try to make it useful. Write down the worst failure before you ship. Build in someone who can stop you. Then act, whether you feel ready or not.
What changes unlock by starting
- You have a written worst-case scenario for every model before it ships.
- You have named who can override you, and told them so directly.
- You review errors on a schedule you keep, not when guilt forces you to.
- You can tell the difference between weight that is useful and weight that is just noise.
