Another small example. I have a clock near the end of my bed. It runs 15 minutes fast. Not by accident, it's been reset many times and then set back to 15 minutes fast. I know it's fast, we even call it the "rocket clock". None of this knowledge diminishes it's effectiveness at getting me out of bed sooner, and making me feel more guilty for staying up late. Works very well.

Glad to discover I can now rationalise it as entirely rational behaviour and simply the dark side (where "dark side" only serves to increase perceived awesomeness anyway).
