Let us finally move to an example that deals again with real FoI regimes. One of the surprises of such regimes is that, as a matter of fact, their very existence remains rather confidential in many countries. Citizens do not exercise their right of access to state-detained documents as much as one might expect. This could be regarded as unfortunate. One may as well consider it necessary, however, at least if we find meaningful the idea of an optimal level of confidentiality of FoI regimes. This optimal level would consist in some active citizens being maximally aware of its existence, and all civil servants being as little aware of it as possible. For if (non-ideal) civil servants know that they are potentially being watched, they may admittedly try to change their behavior for the better. However, they may simultaneously want to hide even further the more problematic aspects of their behavior (e.g., through shifting from written to oral discussions). In other words, in order for the fundamental FoI right to be maximally effective, its existence and exercise may have to remain relatively covert, perhaps unequally known.
