Brief Commentary: A Reexamination of the Effect of Forced Choice on Choice
通过九项预注册复制实验，重新检验了无选择选项对选择份额的影响，发现无选择选项并不系统性地减少特定选项的份额，表明其效应比以往认为的更复杂。
Abstract When conducting studies in which the dependent variable is choice, researchers must decide whether to require participants to select one of the available alternatives or to provide a no-choice option. Prior research published in the Journal of Marketing Research proposed that no-choice options can disproportionately reduce the share of certain alternatives, particularly all-average or compromise options. In this commentary, I reexamine these propositions. I report the results of nine well-powered, preregistered replications of the original studies, which support only a subset of these hypotheses. Importantly, across these replication studies, no-choice options do not systematically draw share from specific alternatives. These findings suggest that no-choice effects may be more nuanced than previously thought and that the conditions under which previously documented effects occur reliably remain unclear. I discuss the implications of these results for theories of decision-making, context effects, and choice deferral. This work aims to update the literature and inform marketing researchers about the consequences of forcing choice versus allowing a no-choice option in experimental design.
