Beliefs about self-control.

It is increasingly recognized that successful self-control is not only determined by sheer willpower, but also by people's beliefs about self-control. While early research has provided evidence that people's implicit theories can moderate their subsequent self-control performance, recent research considers the role of metacognition in self-control more comprehensively. In this review, we present an overview of recent advances in the field, emphasizing self-control beliefs and their potential impact on self-control outcomes. We also stress lay beliefs about self-control as an overlooked topic and promising avenue for future research.
