"This is a book about bad statistics, where they come from, and why they won't go away. Some statistics are born bad – they aren't much good from the start, because they are based on nothing more than guesses or dubious data. Other statistics mutate; they become bad after being mangled ... Either way, bad statistics are potentially important: they can be used to stir up public outrage our fear; they can distort our understanding of the world; and they can lead us tom make poor policy choices" (Quoted from book)
