- Abstract
The identification of an empirically adequate theoretical construct requires determining whether a theoretically predicted effect is sufficiently similar to an observed effect. To this end, we propose a simple similarity measure, describe its application in different research designs, and use computer simulations to estimate the necessary sample size for a given observed effect. As our main example, we apply this measure to recent meta-analytical research on precognition. Results suggest that the evidential basis is too weak for a predicted precognition effect of d = 0.20 to be considered empirically adequate. As additional examples, we apply this measure to object-level experimental data from dissonance theory and a recent crowdsourcing hypothesis test, as well as to meta-analytical data on the correlation of personality traits and life outcomes., Die Autor*innen schlagen ein simples Ähnlichkeitsmaß vor, beschreiben seine Anwendung in verschiedenen Forschungsdesigns und verwenden Computersimulationen, um die erforderliche Stichprobengröße für einen bestimmten beobachteten Effekt zu schätzen.
