Atomic Habits Chapter 17

How an Accountability Partner Can Change Everything


After serving as a pilot in World War II, Roger Fisher attended Harvard Law School and dedicated thirty-four years to specializing in negotiation and conflict management. He founded the Harvard Negotiation Project and collaborated with various countries and world leaders on peace resolutions, hostage crises, and diplomatic compromises. However, it was during the 1970s and 1980s, amid escalating nuclear war threats, that Fisher developed one of his most thought-provoking ideas.


At that time, Fisher focused on strategies to prevent nuclear war and noted a troubling reality: any sitting president had access to launch codes capable of killing millions but would never witness the consequences firsthand, as he would always be thousands of miles away. Fisher proposed a radical solution: "Put that [nuclear] code number in a little capsule and implant that capsule right next to the heart of a volunteer. The volunteer would carry a butcher knife and accompany the President. If the President wanted to fire nuclear weapons, he would first have to kill someone with his own hands. He has to look at someone and face the reality of innocent death.”


Fisher's suggestion shocked many. Friends in the Pentagon responded, “My God, that’s terrible. Having to kill someone would distort the President’s judgment. He might never push the button.” This proposal serves as an inversion of the 4th Law of Behavior Change: rather than making good habits rewarding, it proposes making bad habits immediately painful. 


Just as we are more likely to repeat an experience when the ending is satisfying, we are also more inclined to avoid experiences that end in pain. Pain serves as an effective teacher. If a failure is painful, it gets fixed; if it is relatively painless, it often goes unaddressed. Immediate consequences can prompt rapid learning. For instance, the threat of a bad review compels a plumber to perform well, while the risk of losing customers drives restaurants to produce quality food. The more severe the potential consequences, the quicker the learning process.


We tend to repeat bad habits because they serve us in some way, making them challenging to abandon. One effective strategy for overcoming this is to increase the immediacy of the punishment linked to that behavior. When actions carry immediate consequences, behavior begins to change. Customers pay their bills on time when charged a late fee, while students show up to class when attendance is tied to their grades. People often go to great lengths to avoid immediate pain.


However, it’s essential that the strength of the punishment matches the behavior it seeks to correct. For instance, the cost of procrastination must outweigh the cost of action, and the price of laziness must be greater than the cost of exercise. The imposition of fines for smoking in restaurants or not recycling adds tangible consequences to actions. Behavior only shifts when the punishment is adequately painful and consistently enforced. 


In general, the more local, tangible, and immediate the consequence, the more likely it is to influence individual behavior. Conversely, the more vague and delayed the consequence, the less influence it has. Thankfully, there is a straightforward way to incorporate an immediate cost into any bad habit: create a habit contract.

The Habit Contract


The first seat belt law was passed in New York on December 1, 1984. At that time, only 14 percent of people in the United States regularly wore seat belts, but that was about to change. Within five years, over half the nation adopted seat belt laws. Nowadays, wearing a seat belt is enforceable by law in forty-nine of the fifty states.


It’s not just the legislation that changed behaviors; the number of people wearing seat belts has dramatically increased. By 2016, over 88 percent of Americans buckled up every time they got in a car, demonstrating a significant reversal in the habits of millions. Laws and regulations are examples of how governments can alter our habits through social contracts. As a society, we collectively agree to certain rules that are enforced collectively. Whenever legislation affects behavior—like seat belt laws, smoking bans in restaurants, or mandatory recycling—it exemplifies a social contract shaping habits. The group agrees to act in a specific way, and punishment ensues for those who do not comply. 


Just as governments utilize laws to hold citizens accountable, you can create a habit contract to hold yourself accountable as well. A habit contract is a verbal or written agreement where you commit to a specific habit and outline the punishment for failing to follow through. To enhance your commitment, involve one or two accountability partners who will sign off on the contract with you.


Bryan Harris, an entrepreneur from Nashville, Tennessee, was one of the first individuals I encountered using this strategy. Shortly after the birth of his son, Harris wanted to lose some weight. He drafted a habit contract that included his wife and personal trainer. The contract stated, “Bryan’s #1 objective for Q1 of 2017 is to start eating correctly so he feels better, looks better, and aims to achieve a long-term goal of 200 pounds at 10% body fat.”


Harris then mapped out a roadmap to achieve his ideal outcome, detailing phases for each quarter and daily habits that would contribute to his goal. He also established consequences for failure: if he missed his daily food logging or failed to weigh himself, he would have to dress up for work every day and pay his trainer $200. 


Initially, I thought that such a formal contract seemed excessive, especially with the signatures. However, Harris explained that signing the contract signified seriousness and commitment, stating, “Anytime I skip this part, I start slacking almost immediately.” 


Three months later, having met his targets for Q1, Harris escalated his goals andthe consequences. Missing specified targets had him paying $100 to his trainer, and a failure to weigh in meant $500 to his wife. The most challenging consequence? If he forgot to run sprints, he had to dress up for work each day and wear a hat representing his rival college football team, a bitter pill for the loyal Auburn fan.


The strategy proved effective. With his wife and trainer serving as accountability partners, and the contract clarifying daily expectations, Harris successfully lost weight. 


To make bad habits unsatisfying, your best option is to introduce immediate pain. Crafting a habit contract is a straightforward approach to achieving that. 


Even if you’re not inclined to create an extensive habit contract, having an accountability partner can be immensely beneficial. Comedian Margaret Cho, for instance, engages in a daily "song a day" challenge with a friend, helping them both stay accountable. The knowledge that someone is watching can serve as a powerful motivator. You are less likely to procrastinate or give up because there’s an immediate cost involved. It’s no longer just your personal commitment on the line; it impacts how you’re viewed by others.


You can even automate this accountability process. Entrepreneur Thomas Frank wakes up at 5:55 each morning, and if he doesn’t, he has a tweet scheduled that states, “It’s 6:10 and I’m not up because I’m lazy! Reply to this for $5 via PayPal (limit 5), assuming my alarm didn’t malfunction.” 


We consistently strive to present our best selves to the world. We dress well, maintain good hygiene, and pursue respectable grades because we desire positive feedback. The opinions of those around us matter deeply. This need for approval is precisely why having an accountability partner or signing a habit contract can be so effective.


Chapter Summary


The inversion of the 4th Law of Behavior Change is to make it unsatisfying. 


We are less likely to repeat a bad habit if it is painful or unsatisfying. An accountability partner can create an immediate cost to inaction. 


We care about others' opinions and don’t want to be perceived negatively. 


A habit contract can be employed to impose a social cost on any behavior, making the consequences of neglecting your commitments public and painful.
