There is a prevalent claim in the judgment and decision making (JDM) literature that attention to a piece of information confers weight or importance upon that information. The prevalence of that claim is not commensurate with the empirical evidence the quantity of evidence is sparse, and, is constrained by significant limitations in the methodological approach of previous studies. The current work presents a novel method for covertly manipulating attention to different components of a decision scenario. Using this approach, the current work provides empirical evidence from three multiattribute scenarios in support of a consistent, positive causal relationship between the attention allocated to a piece of information and the influence accorded to it. In addition, the current work demonstrates the viability of crowdsourcing psychological research, including research that involves significant perceptual components.
