Harrison Bergeron Concentration Aid

In the Vonnegut story Harrison Bergeron, the protagonist must wear special headphones. He is more intelligent than average, so to bring his intelligence down to the average level he must wear headphones that produce randomly timed, random noises. This interrupts his train of thought, preventing him from any serious thinking.

There are many items in daily life (pagers, secretaries, kids) that serve the same function, though in a less organized way. A person used to these distractions who can escape them from a short time is often surprised at how productive they become.

Why not use this effect in a controlled manner? I propose headphones just as those used in the story, which a person can wear to practice their concentrating skills. This is analogous to those swimmers who practice wearing loads of ancient ripped up swimsuits, so on the day of the match wearing only the meet suit, they are extra speedy.

These headphones could plug into the computer and receive distractions via the web, to enable a never-repeating repertoire. Then when you really need to be sharp, take the headphones off - your powers of concentration will be unparallelled.
