The law of averages – if you predict enough stuff and use common sense, you are bound to hit some winners. Remember the lady psychic that got national recognition for predicting the assasination of President Kennedy? Jean Dixon, I think, was her name. She became so famous that all the newspapers printed her next several years of predictions. She never got another single one right. If you are a real psychic, you know that this is not how it works. You can’t make broad predictions about things like politics or weather.
