Summary: New research suggests that people need willpower not only to resist temptations in the moment but also to put in place strategies that prevent temptation from arising.

The tale of Odysseus and the Sirens from Greek mythology provides a classic illustration of self-control.
Before sailing past the Sirens—mythical beings whose song lured sailors to wreck—Odysseus has his crew plug their ears with wax and tie him to the mast. He can hear the Sirens’ song but cannot act on the impulse to follow it; his companions block his ability to give in. This raises a key question: was Odysseus relying on willpower, or did he remove his capacity to yield to temptation?
Jordan Bridges, a doctoral student in the Rutgers Department of Philosophy, is a coauthor of a paper in the journal Cognition that explores why this distinction matters. The study examines how people understand the role of willpower in self-control and why the difference between resisting temptation in the moment and arranging one’s life to avoid temptation is important for research and practice.
Researchers have long investigated which strategies reliably help people resist temptations—whether that means stopping after one chip instead of eating the whole bag, or turning off the phone rather than repeatedly checking social media before bed. While individual differences in self-control remain only partly understood, psychologists and behavioral economists have cataloged common tactics people use to manage impulses.
Bridges and colleagues describe two broad approaches. Diachronic regulation involves planning and changing one’s environment or habits over time to reduce exposure to temptations—effectively avoiding situations that call for effortful resistance. Synchronic regulation, by contrast, depends on conscious, effortful willpower at the moment a temptation arises.
Some scholars argue that diachronic strategies are more effective because willpower is costly and often fails. The argument draws support from the mixed results of willpower-based public campaigns—campaigns that sought to curb substance use or other behaviors by urging individuals to exert self-control often showed limited measurable impact.
However, Bridges and her coauthors proposed that this contrast between synchronic and diachronic tactics may be mischaracterized. They suggested that many apparently purely diachronic strategies actually depend on acts of will to implement and sustain them. In other words, people might believe a behavioral prevention strategy works on its own, when in fact willpower played a crucial role in putting that strategy in place.
“We theorized that it takes willpower to implement temptation-avoidance strategies,” Bridges said.
To test how laypeople distinguish between these approaches, the researchers used a multifactorial design intended to separate synchronic and diachronic regulation in people’s judgments. Across four experiments, participants read short vignettes about a character named Mo who faced different temptations—drinking coffee, eating junk food, using social media, and more—and used various tactics to avoid giving in. Participants then rated how much self-control Mo displayed in each scenario.
When the researchers disentangled the two forms of regulation, they found that participants generally identified only synchronic, effortful resistance as genuine self-control. Purely diachronic strategies—plans and behaviors that prevent temptation—were not typically judged to be acts of self-control unless they also involved moments of willpower. In scenarios that mixed both approaches, ratings of self-control depended on the presence of synchronic regulation; participants credited moments of willful resistance rather than the preventive behavior alone.
These findings have implications for how scholars and practitioners discuss and teach self-control. Bridges emphasized the importance of using language that matches ordinary understanding when communicating scientific results.
“Scientific debates sometimes turn on distinctions that don’t match everyday usage,” Bridges said. “If we want to communicate effectively, we should describe findings in terms people recognize.” She noted that people often attribute success to a diachronic measure—like avoiding a tempting environment—when the real driver may have been willpower at key moments: initiating and following through on the plan. Recognizing when willpower is involved can shape how clinicians, educators, and policymakers approach habit change.

“Will-powered: Synchronic regulation is the difference maker for self-control” by Zachary C. Irving et al., published in Cognition.
Abstract
Will-powered: Synchronic regulation is the difference maker for self-control
Philosophers, psychologists, and economists commonly distinguish two ways of exercising self-control. Synchronic regulation involves exerting willpower to resist temptation as it appears. Diachronic regulation involves creating plans or restructuring one’s environment over time to prevent temptation from arising. However, these two categories can overlap in practice.
Agents often rely on moments of willpower to create and maintain diachronic strategies. That overlap can lead observers to credit the preventive strategy itself for success, even when willpower played a pivotal role. To clarify how ordinary people conceptualize self-control, the authors developed a multifactorial method to separate synchronic from diachronic regulation in judgment tasks.
Across four experiments featuring different temptations and including a paradigmatic case based on Odysseus and the Sirens, the researchers found that people tend to regard synchronic regulation—that is, effortful resistance at critical moments—as the hallmark of self-control. Diachronic measures were not usually seen as self-control unless they involved synchronic acts at key points: initiating a plan and following through on it.
Together, these results indicate that ordinary conceptions of self-control treat synchronic regulation as the central, difference-making element. Recognizing this folk concept has implications for how researchers and practitioners describe, study, and support efforts to change habits and resist temptation.
