Abstract

Scientific epistemology, which showed innovative developments in the last century, has been expected to involve various implications. Among other things, penetrating criticism of absolute truth to scientific theories is an important one. The concepts developed in relation with this knowledge skepticism include falsifiability, holism and theory ladenness. It looks, however, still sparse to develop their implications to research designs employed in usual research programs. This article attempts to provide five important requirements for obtaining evidences of high quality, and to discuss the relationship of these requirements with scientific epistemology. Special emphases are placed on how to cooperate for obtaining many individual scientific findings and also on how to take account of relativism in scientific researches.
