Abstract
Abstract Virtually all scientific outlets, including the most prestigious journals, have implemented strict rules of α and (1–β) control, supposed to quantify the probability of a significant result assuming H0 and H1, respectively. However, estimation of α and β rests on the untenable assumption that a systematic effect ΔY in the dependent variable cannot be brought about by any other causal influence than the influence ΔX stated in H1 and negated in H0. Yet, in a given study, empirical evidence on ΔY related to ΔX can always reflect extraneous causal influences, because no treatment or measurement tool affords a pure measure of X and Y, respectively. Consequently, α and β cannot quantify error probabilities in specific studies.
期刊介绍：
Basic and Applied Social Psychology (BASP) emphasizes the publication of outstanding research articles, but also considers literature reviews, criticism, and methodological or theoretical statements spanning the entire range of social psychological issues. The journal will publish basic work in areas of social psychology that can be applied to societal problems, as well as direct application of social psychology to such problems. The journal provides a venue for a broad range of specialty areas, including research on legal and political issues, environmental influences on behavior, organizations, aging, medical and health-related outcomes, sexuality, education and learning, the effects of mass media, gender issues, and population problems.
