That which has the superficial appearance of science, usually with its jargon and other trappings, but which fundamentally is not science, is called pseudoscience (a.k.a. "junk science," "quackery," etc.). Whereas the scientific method involves objectivity (enhanced by peer review, replicability, and other means) and letting the best evidence lead to the most likely solution, pseudoscience tends to be non-falsifiable (that is, there can be no evidence to disprove it). The pseudoscientist typically begins with a conviction and works backwards, seeking only the evidence seeming to justify that belief. For example, astronomy and evolutionary biology are sciences, while astrology and creationism (and Intelligent Design) are pseudosciences.
