The Role of Expectations in Set Size Evaluations
This research explores whether set-size judgments are assimilated or contrasted with set-size expectations. Participants were told to expect either a limited or extensive set of products, and then faced a limited, moderate, or extensive choice set. Expectations had little effect for the limited or extensive sets, yet significantly modified reactions to the more ambiguous moderate set. Those expecting a sparse set exhibited contrast and viewed the moderate set as highly complete, and overwhelming, with a low choice confidence. Participants expecting an extensive set also exhibited contrast, viewing the moderate set as incomplete and restricted, while expressing high choice confidence.
