A policy can protect its author from blame more effectively than it protects its intended beneficiary.

Policies are often written with an eye on what happens if this goes wrong. That instinct produces documents full of protections, sign-offs, and disclaimers that shield the institution and its author very effectively, while the person the policy was supposedly for gets whatever is left. The intention was sincere and the defensive drafting quietly outperformed it.

Read any policy you rely on and ask what it guarantees you as opposed to what it protects the writer from. If you draft them, notice how much of your text is about liability and how much is about delivery. The ratio tends to be honest even when the summary is not.
