Long policy documents are also a problem for human agents. Without special training no one will retain 180 pages HR employee handbook, fire codes, OSHA safety rules, FCC regulations, the US legal code.

If the stakes are high, e.g, proceeding in ignorance could lead to prison time, people will favor inaction, even if the policy technically permits a corner case. If the stakes are low, people will completely override policy for the path of least resistance.
