How to Get Information to Flow Backward

A certain Mr. Marc Tarrasch of Los Altos, California wrote in to Newsweek magazine last week to complain about actor Johnny Depp’s disparaging comments about America in 2003. Depp was quoted by the German magazine Stern as likening America to “a dumb puppy that has big teeth that can bite and hurt you” and “a broken toy.” Says Mr. Tarrasch:

Apparently, it is acceptable for Depp to make movies in Hollywood while at the same time publicly disrespecting the country where he was born and from which he reaps enormous financial benefits. Until Depp retracts his foolish statements, I will not pay a dime to see any of his films, no matter how wonderful an actor Newsweek thinks he is.

Johnny Depp promoting Pirates of the Caribbean: Dead Man's ChestWe can discuss the merits of Mr. Depp’s remarks — and Mr. Tarrasch’s criticism — some other time. The point is, Johnny Depp did issue a public apology. In fact, within 48 hours of the article’s publication, he claimed that his words had been misquoted and taken out of context:

There was no anti-American sentiment… My deepest apologies to those who were offended, affected, or hurt by this insanely twisted deformation of my words and intent.

(Let’s also put aside the question of whether Depp’s apology was sincere, or whether he was just engaging in some frenzied damage control after seeing the negative reaction his comments received in the press. Johnny Depp doesn’t strike me as the type of guy who would apologize for a political statement unless he sincerely meant to apologize. Do you think an actor who once jumped at the chance to star in a black-and-white film about an unknown cross-dressing homosexual B-movie director really cares if his political views affect his box office draw?)

So the news of Johnny Depp’s retraction did not reach the editors of Newsweek, and they printed Mr. Tarrasch’s letter. One can only wonder how many of Newsweek‘s circulation of 4 million heard about the whole flap for the first time through this letter and decided to boycott Depp’s film Pirates of the Caribbean: Dead Man’s Chest this past weekend. A few hundred? A few thousand? Could Mr. Tarrasch’s letter have been one of the flakes in a snowball of conservative resentment that led to Pirates‘ disappointing second-weekend box office?

There’s a technological point to be made from all this, and here it is: information only flows one way. It goes forward, not backward.

Like the stuff that flew out of Pandora’s box, information is almost impossible to control once it’s released. Attempting to retract information that’s already out there is doubly difficult, and I’m willing to bet that Depp will be hearing conservative tirades about his supposed anti-American statements for decades to come.

It’s a problem that’s been a part of the human experience since the very beginning. And now the problem is ingrained in the very structure of the web, our greatest informational tool. Hyperlinks only point in one direction. From a technical standpoint, every page on the web is completely ignorant of the pages that link to it. As soon as you click on a hyperlink, the only connection back to that original page is through your browser’s history stored on your local machine. Move a page on the web or change its content, and watch the hundreds of linked pages dumbly continue to insist that the data is still there.

But here’s the really fascinating thing. For the first time in human history, we may be on the verge of finding ways to allow data to flow in the opposite direction. And this could very well be one of the small technologies that changes the world.
