Attitudes do not necessarily translate into behaviors, as there is a gap between attitudes and behaviors. The current study selected self-control fatigue and information source credibility to explore the gap between attitudes and behaviors. Experiment 1 explored the effect of self-control fatigue on attitudes and behaviors. Experiment 2 based on experiment 1 to explore the effects of self-control fatigue and information source credibility on attitudes and behavior. Experiment 2 found that compared with the control group, the self-control fatigue group had a weaker attitude towards sugar, but more participants chose the sugar-sweetened beverages. Self-control fatigue widened the gap between participants' attitudes and behaviors. Experiment 2 found that under the persuasion of high information source credibility, participants in the self-control fatigue group not only had a weaker attitude towards sugar, but also chose the sugar-sweetened beverages less frequently. The information source credibility shrinks the gap of attitude and behavior. In summary, this study found that under the influence of high information source credibility, individuals with self-control fatigue are more likely to change their attitudes and behaviors.
