Denying scientific data, a crank considers their opinion to be the only correct one...
Psychics, healers, magicians, and other charlatans – the list of swindlers is constantly growing.
However, it should be understood that pseudoscience is not philosophy, religion, fiction, or humor...
It has transformed from a marginal field into a well-organized force with considerable financial resources. Websites and online communities are dedicated to the activities of scientific cranks. There is even a commission of the Russian Academy of Sciences to combat pseudoscience. However, in all cases, the focus is usually on individual facts.
