Abstract

Abstract A theory propounded by Popper, a philosopher of science, suggests that the difference between true science and pseudoscience is that the former is testable, whereas the latter is not. In testing scientific hypotheses, researchers seek to prove it wrong (“falsify”). If efforts to falsify do not result in providing evidence of an inherent failing of the postulate, the premise is tentatively adopted as a workable hypothesis that may be applied to the future, like inquiries. This article discusses the degree of acceptance Popper's theory has among scientists as well as the manner in which it gained prominence among forensic scientists and some courts.
