A policy is a document until something goes wrong. Then it becomes an instrument of investigation: someone has to determine what happened, whether it broke a rule, who was allowed to approve the conduct, and what evidence exists. Most AI policies written as statements of values fail at exactly that moment, because they were never built to answer those four questions.
The tell is the language. Templates commonly open with commitments to fairness, accountability, and transparency, and then list prohibited behaviors such as uploading confidential data or using AI for employment decisions (Lattice's sample policy). Those prohibitions are a reasonable starting point, but they describe categories rather than observable acts. "Confidential information" means something different to a lawyer, a salesperson, and a support agent. An investigator reading a log file cannot map an event to a category without a definition that was written in advance.
The second tell is scope drift. A policy that only addresses employees quietly excludes contractors and vendors, even though those groups usually have the same access. One university policy solves this by stating that it applies to all employees and to anyone performing work or services for the institution, regardless of whether the tool runs on university, personal, or third-party devices (St. John's University Policy 1038). That single sentence closes an argument that otherwise consumes the first hour of an incident review.
The third tell is the absence of a test. A rule you cannot check is a preference. The rest of this article is about converting preferences into checks.
