## Slower thinking

A hallucination is a confident generation that is wrong on a verifiable fact. They happen. They will continue to happen. The interesting question is not whether they happen but where they happen, who catches them, and what the cost is of the ones that escape.

In a Fidelic deployment, the agent's work is in front of the team in [Slack](https://slack.com/). Most hallucinations are caught in the draft — the team reads the brief, sees the false claim, and corrects it before the brief ships. The cost is a draft a teammate had to fix, which is the same cost as a draft a junior teammate had to fix. The agent does not improve at hallucinating less by being trusted more; it improves by the constitution gaining specificity at the points where the agent has historically gone wrong, and by the eval suite catching the regressions.

The hallucinations to actually worry about are the ones that escape. Those have specific shapes: a fact that nobody on the team is positioned to verify, a claim that sounds right because it matches the team's existing assumptions, a citation the agent invented and the team didn't check. The right response is not to refuse the agent. It is to require citations the agent can produce on demand, to add the specific failure category to the constitution as a refusal, and to add an eval test for the failure so the next deployment of the agent fails the test rather than the customer.

There is also a category of hallucination buyers worry about that is rarer than they think: the model lies in customer-facing contexts. In a deployment where the agent does not talk to customers directly — the pattern most CS deployments use, with the agent drafting and a human shipping — the hallucination's path to a customer is mediated by a teammate who is paid to read drafts. That doesn't eliminate the risk. It changes the cost of the failures that happen from public to private. Private failures get fixed. Public failures get screenshot.
