Three experiments examined whether perceiving thoughts as coming from internal versus external origins are more impactful on attitudes. Participants generated either positive or negative thoughts about different attitude objects, including different diets, and plastic surgery. Then, participants were induced to think that their thoughts came from the self or from an external source. In Experiment 1, participants induced to believe their thoughts originated from the self versus an external source relied on them more to form their attitudes. Experiment 2 demonstrated that when the external origin was associated with properties of validity, people relied on their thoughts more than when thoughts were perceived to come from an internal origin associated with low validity. Experiment 3 showed that the impact of thought origin on evaluations was mediated by greater liking for one's thoughts when they originated in the self.
三项实验检验了将思维感知为源自内部还是外部对态度的影响更大。参与者对不同的态度对象生成了积极或消极的想法，包括不同的饮食和整容手术。然后，参与者被引导认为他们的想法来自自我或外部来源。在实验 1 中，与自我相比，参与者更倾向于依赖被引导为源自外部来源的想法来形成他们的态度。实验 2 表明，当外部来源与有效性的特征相关联时，人们会比将思维感知为来自与低有效性相关联的内部来源时更依赖于自己的想法。实验 3 表明，思维来源对评估的影响是通过当思维源自自我时，人们更喜欢自己的想法来中介的。
