Book Reviews: "Certainly an eye-opening and thought-provoking introduction to how to use one抯 power of reason in discriminating sense from nonsense." Booklist "This is a well-written, interesting, easy-to-read book. I recommend it for middle-school students and adults." Science Teacher, February 1986 "An articulate introduction to the art of logical thinking匰tressing at all times the value of a questioning mind, the authors cannily use statistical subjects that are of interest to young people, such as the accident rates of teenage drivers 匛venhanded in its treatment of issues, the book is outstanding in its clarity, sometimes surprising in its conclusions, and fascinating." The Horn Book How Do You Know It抯 True? has joined my short list of hallmark children抯 literature titles." Linda Winkler, St. Petersburg Times
