One style of conducting scientific research involves the application of theoretical propositions to an empirical domain under investigation. The investigator plans his research in terms of the theoretical propositions and states his findings in these terms as well. We wish to examine not the merits of this style of research but a difficulty inherent in it. The difficulty concerns what is to be done when disconfirmative results are produced by some discrete study or experiment in the course of such research.
