Popper's Falsificationism Methodology and Decision-making Science

The purpose of studying scientific activities in scientific methodology lies in probing the basic rules that scientific discovery and scientific examination follow and in offering the rational basis for scientific prediction and decision. The research of scientific methodology in our country mainly concentrates on 2 stages: scientific discovery and scientific examination ,but comparatively the weakness lies in studying the application stage of scientific methodology--scientific prediction and scientific decision . The author holds that Popper's falsificationism methodology has exerted an important influence on decision-making science in both the basic theory of decision-making science and the method of decision-making science by comparing falsificationism methodology with decision-making science.
