Recent research on decision-making has explored the presence of compromise and attraction effects in choices. The compromise effect is a theory derived from the principle of loss aversion while the attraction effect is an extension of the tradeoff contrast effect. However, previous research has yet to examine the influence that consumer deliberation has on the compromise and attraction effects. Common sense suggests that consumers make more satisfying decisions when the options are closely related with them. However, studies have shown that various emotions will be induced in the process of deliberation and thus result in different decisions. The research method adopted is laboratory experimentation. The purpose of the study is to determine whether the deliberation process strengthens or diminishes the compromise and attraction effects. The main conclusions are as follows. Experiment One indicates that, in contrast to intuitive decision-making, the compromise effect is indeed strengthened after the deliberation process, but the increase is not significant. Experiment Two shows that, in contrast to intuitive decision-making, the attraction effect is diminished after the process, and the decline is quite significant. The study finds that the attraction effect is significantly weakened by deliberation.
