Random Word Generator

Passphrases and the arithmetic of guessing

The famous xkcd comic that popularised 'correct horse battery staple' was making a precise mathematical argument, not a joke. Four words drawn at random from a list of a few thousand yields an enormous number of possible combinations — comfortably more than a short password bristling with symbols — while being genuinely memorable, because human memory is built for words and hopeless with arbitrary characters. The security rests entirely on the randomness of the selection. Four words you picked yourself are not four random words: people gravitate towards related concepts, common nouns and personally meaningful terms, and an attacker's guessing strategy accounts for that. The dice, or the generator, must do the choosing.

Randomness as a creative tool

Using arbitrary input to unstick thinking has a long pedigree. Brian Eno and Peter Schmidt's Oblique Strategies deck gave musicians a random instruction when they were stuck. Edward de Bono's lateral-thinking techniques formalise the random-word method as a deliberate provocation. The mechanism is the same in each case: creative blocks are usually not a shortage of ideas but a rut, an over-travelled path that your mind keeps returning to. An arbitrary word cannot be reached from that path, so connecting it to your problem forces a genuinely new route. The technique feels faintly ridiculous, and it works often enough that people who have tried it seriously keep coming back to it.
