Scientific, or Intelligent-Design, Creationism; Astrology; Homeopathic Medicine: all seem to be immortal, like the Undead. This book is an excellent attempt to drive stakes through the hearts of the monsters.
Science requires patient subjection of all hypotheses about the world outside oneself, including one's own favorites, to rigorous statistical testing through experiment. Repeated application of the foregoing general procedure to numerous related hypotheses may, with luck and inspiration, result in a body of tentative, mutually-reinforcing working rules which hang together in a theory or alternatively, a self-consistent model of external phenomena. Pseudoscience is much easier and more quickly gratifying: it only requires the assertion, as an ultimate truth, of a body cherished hypotheses; the only task remaining is to be on the lookout for facts, real or apparent, that support one or more of these hypotheses, or ad hoc embellishments thereof; any facts contradicting them may be explained away or, if such is not possible, ignored.
The authors have provided here a methodical survey of scientific method and mindset, as well as strategies and enthusiasms of peudoscience, with copious illustrative examples. This frankly polemical work can be an antidote for quackery, if the reader keeps an open mind. That's about the best one can hope for: quacks wouldn't be reading it anyway.
