“If you want to keep a secret,” George Orwell advised in “1984,” “you must also hide it from yourself.” So the latest stricture seems to demand from the Office of the Director of National Intelligence, the federal uber-agency of all things secret. The office, which oversees 16 government intelligence agencies, issued a new policy in April that will seriously constrain the existing practice by which officials comment informally to the press and public when obvious issues are stirred by leaked information and unauthorized disclosures.

We consider this process an unavoidable but decidedly healthy way of life in Washington. But the updated policy sternly requires that an informed official who’s been regulating his own give-and-take in this important area now submit for advance approval an outline of the topics expected to arise in “unstructured or free-form discussions.” Otherwise, the policy memo states with a certain alarm, an official’s utterances could be construed as a validation of leaked information and “cause further harm to national security.”

The new prepublication review policy provides that the office’s current and former employees and contractors may not cite news reports based on leaks in their speeches, opinion articles, books, term papers or other unofficial writing, according to a report by Charlie Savage of The Times. Semaphore seems to have been overlooked as a medium, but we get the point.

The reassuring fact is that all manner of officials, from the president on down, occasionally speak authoritatively about an issue that might be informed by some bit of leaked information. It’s the mother’s milk of capital conversation. But don’t tell that to the director of national intelligence, James Clapper Jr., whose passion for keeping secrets at any cost — even his own reputation for honesty — has become legendary. It was Mr. Clapper who was asked at a Senate hearing last year whether the National Security Agency collects “any type of data at all on millions or hundreds of millions of Americans.”
