How do individuals form impressions of options when they have access to population-level descriptions and sample-level experiences? In the current study, participants were given descriptions of two options and were then given the opportunity to learn about the options. Results showed that inaccurate descriptions led to poorer performance than accurate descriptions. Additionally, the influence of descriptions was positively related to the perceived credibility of the source of descriptions. Therefore, perceived source credibility amplified the effect of the accuracy of descriptions of options. A mathematical model is proposed to describe how descriptions are combined with experiences in dynamic choice tasks. |
