Self-control can be seen as making choices about our own preferences. This study looks at how we choose between different options based on our preferences. By examining how we make decisions before and after we know the outcomes, researchers found that our second-order preferences play a big role in self-control. This means that our preferences about our own preferences can influence our choices. The study suggests that understanding these second-order preferences can help explain why we sometimes make choices that go against our best interests.
