The fundamental difference between science and pseudoscience is that science is based on rigorous methodological evidence, constant questioning and constant upgrading to new ideas and knowledge, while pseudoscience is based on solid convictions which include all theories, data and claims that, at first glance, seem scientifically proper, or do not meet scientific canons nor are scientifically justified. In modern Western societies, with pseudoscience, superstitions and beliefs of the New-Age make up a special complex of beliefs, which also don’t have any scientific arguments. Pseudoscience appears in several forms. The most common are: creationism (theological and scientific opposition to the theory of evolution), astrology (based on the belief in the divinity of the planet, in other words; the ability to read the messages of gods based on their movement) and alternative medicine (treatments that are not scientifically sound and consist mainly of the placebo effect). Conspiracy theories are a form of pseudohistory. There are many pseudoscientific stories that are constantly upgraded. Belief in pseudoscientific knowledge today is spread around the world thanks to the development of modern communications technology, "democratization" of knowledge and the decline of belief in traditional institutions, including science. To contemporary postmodern society, pseudoscience offers a stable identity, control of their own lives, comfort, the possibility to control health etc.
