Pseudoscientific studies don't adhere to the philosophy and methods of science.
Supermarket tabloids are outstanding sources of pseudoscientific hogwash.
For example, one recent issue had articles about aliens killing whales and how tongue twisters cause brain damage. Perhaps one of the most pervasive pseudoscientific idea is astrology with psychic hot lines and palm readers a close second. One of my favorite pseudoscientific claims is that the Shroud of Turin, a cloth with an apparent image of Jesus, is the actual burial shroud. Botanical science and pseudoscience. Perhaps chief among them is Cleve Backster, Mr. Lie Detector.
