To overcome indecision, run for 45 minutes to clarify your thoughts, or use randomness (such as a coin toss) to reveal your true preference through your immediate emotional reaction.

The idea of running to clear one’s mind is based on solid scientific foundations regarding the impact of exercise on the brain. A meta-analysis by Chang et al. (2012) shows that a session of aerobic exercise temporarily improves cognitive functions and mental flexibility, which are essential elements for decision-making. While the popular explanation involving 'endorphins' is somewhat reductive—work such as the review by Heijnen et al. (2016) highlights the role of other well-being molecules such as endocannabinoids instead—the post-exercise mental clarity effect is very real. As for the coin toss trick to reveal one’s preferences, it is validated by behavioral psychology. An experimental study by Schmid and Betsch (2021) confirms that using a random tool allows one to bypass mental overload by triggering an immediate intuitive reaction (relief or disappointment), which instantly clarifies our true desire.
