It is of central importance to the sciences and plays a role in various other fields, like epistemology and law. There is no general agreement on how the terms evidence and empirical are to be defined. Often different fields work with quite different ...

[1] [2] Modern science is typically divided into two or three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the social sciences (e.g., economics, psychology, and sociology), which ...
The problems of underdetermination and theory-ladenness are two obstacles that threaten to undermine the role of scientific evidence. Philosophers of science tend to understand evidence not as mental states but as verifiable information, observable physical objects or events, secured by following the scientific method.
