Brief Summary

Prior research has shown that the context in which program options are presented to consumer impacts consumer choice (known as the 'decoy effect'). The aims of this study are to: (1) test whether the decoy effect can impact smokers' selection of hypothetical tobacco treatment options; (2) examine sociodemographic moderators of the decoy effect; and and (3) examine whether presenting the time and clinical effectiveness of of the different treatment options modifies the decoy effect.
