Evolving choice sets: The effect of dynamic (vs. static) choice sets on preferences

摘要: Abstract Most decision-making research examines static choice sets, with fixed options presented all at once. In contrast, people often make decisions from dynamic in which new alternatives arise during the decision process. We show that compared to a set, set can systematically affect preferences, even when final is an identical of options. Moreover, presentation have opposite effects on preferences. To explain these patterns we propose unified theory based perceived variance attribute distribution. When increases focal attribute, preferences shift towards option best attribute. reduces non-focal Five studies examine this proposal using asymmetrically dominated and compromise sets.
