Scientism may refer to science applied "in excess". The term scientism can apply in either of two senses:
- To indicate the improper usage of science or scientific claims. This usage applies equally in contexts where science might not apply,such as when the topic is perceived to be beyond the scope of scientific inquiry, and in contexts where there is insufficient empirical evidence to justify a scientific conclusion. It includes an excessive deference to claims made by scientists or an uncritical eagerness to accept any result described as scientific. In this case, the term is a counterargument to appeals to scientific authority.
- To refer to "the belief that the methods of natural science, or the categories and things recognized in natural science, form the only proper elements in any philosophical or other inquiry," or that "science, and only science, describes the world as it is in itself, independent of perspective" with a concomitant "elimination of the psychological dimensions of experience."
