The word “pseudoscience” is used to describe something that is portrayed as scientific but fails to meet scientific criteria. This misrepresentation occurs because actual science has creditability (which is to say it works), and pseudoscience attempts to ride on the back of this credibility without subjecting itself to the hard intellectual scrutiny that real science demands. A good example of pseudoscience is homoeopathy, which presents the façade of a science-based medical practice but fails to adhere to scientific methodology. Other things typically branded pseudoscience include astrology, young-Earth creationism, iridology, neuro-linguistic programming and water divining, to name but a few.
