I'm not a great fan of the 'unreliable narrator' device. I think it's become rather overused, and it's rarely done really well.
However, as I discussed last week, I sometimes enjoy taking an idea to extremes. And a year or so ago, I tried this approach with an idea for a humorous short story that played around with the notion of the unreliable narrator.
It also drew upon my concerns about the direction that our technology is taking these days. We often read about the possibility of user-interfaces for portable microchip-controlled devices that can be wired directly into our brains. I began to think of what a 'next generation' i-Pod might be like in 10 or 20 years; and I figured it would probably become possible to 'listen' to music or 'watch' films via a direct neural connection without any actual sound or visuals. And, if so, it wouldn't stop there; somebody would figure out a way to use this technology to implant thoughts and memories - perhaps without our being aware of the fact, creating a new consciousness that would be indistinguishable from our 'reality', a cocktail of truth and fiction.
So, my story was about a visionary inventor who broke away from working for Apple or whoever to develop his own prototype of such a device. His rationale was that most people are unimpressive in conversation because they lead such dull lives; our reality is too boring - but a little creative lying could make us much more interesting and entertaining people, immediately improving our social lives and making us more attractive to the opposite sex. Hence, he has created a Lie Injector, a portable device that gives you more diverting things to talk about.
But of course, he's been trying it out on himself. So, when he tells you about his invention, how can you believe him?
