We Have Better Ways to Break Habits Than Willpower. Why Don't We Use Them?

Nicotine patches have helped many smokers quit, and apps have supported people trying to shun social media's infinite scroll. And yet the fear of judgment drives people to rely on willpower to confront negative behaviors, even if they're less effective, says research by Julian Zlatev.

The deadline on an important work project is looming, but you keep getting distracted by news stories and silly cat videos online. Even though installing an Internet-blocking app might help you stay focused, you resist the idea, telling yourself you should have the willpower to white-knuckle your way through that critical project.

But first, just one more cat video …

Research has shown that people are more likely to follow through on their goals, whether it’s boosting productivity at work, improving grades at school, losing weight, or smoking less, when they use so-called commitment strategies—external aids like Internet blockers, nicotine patches, and swear jars. At the same time, studies show that few people use these supportive strategies. Why?

We know these kinds of strategies are helpful, and we know they tend not to be used at the rate you would expect them to.

They fear that doing so may expose a weakness: a lack of self-control that would make others judge them harshly, says Harvard Business School Associate Professor Julian Zlatev in a recent paper published in the Journal of Personality and Social Psychology: Attitudes and Social Cognition. The findings come at a time when people everywhere are struggling to turn away from the infinite scroll of TikTok videos and Facebook posts, spending more than two hours browsing social media each day.

“We know these kinds of strategies are helpful, and we know they tend not to be used at the rate you would expect them to,” says Zlatev. “One potential reason is that they might be saying something about who you are as a person that might lead others to evaluate you negatively, and that’s driving people’s hesitancy.”

Zlatev coauthored the research with Ariella Kristal, a postdoctoral scholar at Columbia Business School and former HBS doctoral student.

Why people count on willpower

Zlatev says commitment strategies can be extremely effective, such as partnering with a friend to remain accountable about reaching a goal, whether it’s eating healthier, exercising more, or drinking less. Also effective: building in repercussions for failing to achieve a goal, such as committing to donating to a charity—perhaps even a cause the person disagrees with.

“The idea is that to be self-controlled, you have to put aside activities you’d rather be doing, which can be difficult in the moment, so you set up this system to help you,” says Zlatev.

The alternative is relying on willpower to force your way through a situation, whether it’s finishing a report on deadline rather than scrolling Instagram or getting to the gym instead of lounging on the couch. Since willpower requires significant effort, Zlatev and Kristal surmised that perhaps people see those who use it as superior to those who rely on external aids.

In testing this hypothesis, the researchers found:

People trust others who use willpower more than commitment strategies. The researchers asked 400 online participants to give a small amount of money to one of two partners, saying the partner could choose to keep the entire amount or give some of it back. Meanwhile, participants were told that one of the partners used willpower to resist checking out social media sites while working, and the other used a blocking app. Overwhelmingly, participants chose to give their money to the first partner, 69 percent compared to 31 percent, showing that they trusted the person who used willpower more to give back some of the money. The results indicate that participants believed the person who used willpower put in more effort and was therefore considered more trustworthy.

But that way of thinking may be flawed, Zlatev says. “There’s an argument to be made that the person using a commitment device might both care more and be more self-controlled because they are thinking about doing this in advance, rather than leaving it to the last minute—and that maybe it even takes more effort to sign up for the program,” says Zlatev.

In fact, in a follow-up study, not yet published, he and Kristal found evidence that the person who chose to use the commitment strategy was more intrinsically motivated to succeed.

People question the integrity of those who choose commitment strategies. In later studies, Zlatev and Kristal asked participants to rate people on their degree of integrity based on their use of a commitment strategy involving paying a friend $5 if they failed to follow through on a goal to avoid alcohol or junk food, get a flu shot, or go to the gym. In every case, the researchers found that participants rated someone who used that strategy as having less integrity than someone who didn’t.

People worry that using a commitment strategy makes them look bad. In another study, participants were less likely to choose an external commitment strategy if they thought others might find out.

How to combat commitment anxiety

All of this leads to a conundrum: If using commitment strategies is helpful in achieving goals and may even represent more dedication to the task at hand, can people be convinced to use them more? “It will require some way of making people feel more comfortable using them,” Zlatev says.

If a manager puts one of these strategies in place, it’s not the employee’s decision, so that might lessen the negative evaluation.

In a business setting, he notes, one possible solution is to take away the choice of using commitment techniques, for example, by requiring social media blockers on company computers. “If a manager puts one of these strategies in place, it’s not the employee’s decision, so that might lessen the negative evaluation,” Zlatev says. One downside, however, is that employees have less freedom over how they get their work done, Zlatev says.

As an alternative, a boss might consider providing a menu of options of different commitment strategies while presenting information on their efficacy to lessen the stigma of using them. “If it’s institutionalized as part of the system,” he says, “then maybe it provides cover for someone who ends up choosing it.”

Either way, Zlatev hopes that as awareness grows about the usefulness of these strategies, more people might see them as helpful ways to achieve their goals—and also stop looking down on others who use them. After all, he says, willpower alone often doesn’t work.
