Part of the problem may be that so much of the really valuable knowledge is so politically incorrect the organization cannot officially endorse passing it along. The grizzeled NCO who admonishes a young private that "it is better to be tried by twelve than carried by six" is imparting life saving knowledge; but not the type that DOD can endorse. The same applies to the GS-15 telling the GS-9 "some regulations are enforced more rigeroulsly than others". And one of my favorites on ethics "If it is worth carrying past the garbege can, you can't keep it. So smile politely, nod appreciatively, thank profusely and make sure your hosts/visitors don't notice when you trash it."
