Chapter 1: The Hidden Struggle of Self-Control

When we think we’re doing nothing, it might not be as simple as that. In fact, choosing not to act on an impulse can trigger a complex mental dialogue: “I really want to give in,” “But it's not in my best interest,” “What if I just indulge this once?” This inner turmoil illustrates that exercising self-control can be extremely taxing, consuming valuable mental energy. Recent research has quantified the cost of self-control in a compelling way.

A study by Raio & Glimcher, titled “Quantifying the subjective cost of self-control in humans,” involved 138 dieters who were deliberately made hungry. The researchers identified their most tempting foods and set up an auction game where participants could bid to avoid being in a room with their favorite snack. Each participant started with $10 and had a mere 2% chance of their bid being selected. If they didn’t win the auction (which was the case for 98% of the time), their desired food was placed in front of them for 30 minutes. During this time, they could re-bid to remove the food.

The results revealed that, on average, dieters were willing to bid about 15% of their $10 to alleviate the discomfort of resisting temptation—approximately $1.50. They preferred to keep their full amount but were ready to sacrifice a little to avoid the struggle of self-control. Alarmingly, 22% of participants succumbed to temptation and ate the food, indicating the difficulty of maintaining self-control. Those who gave in were acutely aware of their challenges, bidding significantly higher than others. Furthermore, stress levels influenced their willingness to pay to escape self-control.

In a follow-up experiment, the researchers introduced a $15 penalty for consuming the food. With this looming consequence, none of the participants caved in, and their bids increased to around $3—double the initial amount. This finding illustrates that the perception of greater costs associated with failure can drive individuals to invest more in avoiding temptation.

Chapter 2: The Power of Pre-Commitment

The bids in the aforementioned experiments acted as a form of “pre-commitment.” Understanding our tendency to falter in self-control, we can implement clever strategies to mitigate this weakness. Pre-commitment engages different cognitive processes, making it feel less burdensome than traditional self-control efforts. It often feels like a proactive measure rather than an arduous battle against temptation.

We see various examples of pre-commitment in our daily lives. For instance, in financial decisions, individuals frequently impose limits on their credit cards or decline interest-free installment options for large expenses to prevent impulsivity.

A relevant study conducted in 2002 examined how students at MIT pre-committed to deadlines for assignments. Students had the option to set earlier deadlines for three papers or push for a single final deadline. Surprisingly, only 27% opted for the flexible approach; most students chose to commit to earlier deadlines, despite the penalties for missing them. They recognized the risk of procrastination and imposed restrictions on their own freedom to ensure timely submissions.

When pre-commitment isn’t feasible and you find yourself battling temptation, sometimes you just need to dig deep and do your best. Here’s a brief video showcasing children grappling with their desires:

Chapter 3: Practical Tips for Avoiding Temptation

The most effective strategies for steering clear of unhealthy behaviors involve some type of pre-commitment. Even those with strong self-control can benefit from reducing the need to resist temptation altogether:

• Keep Temptations Out of Sight: Cravings are far less potent when they aren’t visible. For instance, in a grocery store, a smart tactic is to steer clear of aisles stocked with your favorite unhealthy snacks—out of sight, out of mind.
• Try Temptation Bundling: Combine healthy but challenging tasks (like exercising) with activities you enjoy. For example, promise yourself to listen to your favorite playlist only during gym sessions, providing added motivation to go.
• Make Commitments Public: Public commitments carry greater weight than private ones. Similar to students who set stringent project deadlines, enhance your commitment to healthier choices by sharing them with friends and family, creating a support system that holds you accountable.
