How Self-Regulation Relates to Decision Fatigue
Research indicates that decision fatigue is often linked to a lack of self-regulation. Self-regulation refers to the ability to manage one’s emotions and behaviors, and individuals who frequently engage in self-regulatory acts are more prone to experiencing decision fatigue. For instance, individuals who make a conscious effort to adhere to a healthy diet and resist the temptation of unhealthy food, or those who strive to quit smoking or drinking, are constantly exerting self-regulation. Consequently, they are more susceptible to decision fatigue not only in other aspects of their lives but also within their primary area of focus.
Situational Factors
Research has revealed that situational factors have a significant impact on decision fatigue. The time of day, in particular, can greatly influence people’s decision-making abilities. Numerous studies have demonstrated that individuals tend to make poorer decisions as the day progresses.
For instance, one study conducted with students taking standardized tests found that their decision-making abilities declined as the day went on. Furthermore, another study discovered that individuals tend to make fewer morally sound decisions later in the day. These findings are not limited to students but also extend to various professionals, including medical practitioners.
A study conducted in 2015 specifically examined the decision-making patterns of doctors. The results indicated that doctors were more likely to prescribe unnecessary antibiotics as the day progressed, suggesting the presence of decision fatigue within the medical profession as well.
