The Role of Family and Friends in Shaping Your Habits

Chapter Overview

As part of the Second Law of Behavior Change (Make It Attractive), Chapter 9 tackles the profound gravitational pull of our social environment. We are, at our core, herd animals. We want to fit in, to bond with others, and to earn the respect and approval of our peers. Such inclinations are essential to our survival.

James Clear explains that the culture we live in determines which behaviors are attractive to us. We unconsciously soak up the habits, attitudes, and behaviors of the people around us. If you want a habit to become permanent, the most effective strategy is to join a group where your desired behavior is the normal behavior.

This chapter explores how we imitate three primary groups: the close (our family and friends), the many (our broader culture or society), and the powerful (those with status and prestige).

The Power of Social Influence

For most of human history, our ancestors lived in tribes. Being separated from the tribe—or worse, being cast out—meant certain death. Because of this, the desire to fit in is literally hardwired into our biology.

When we are faced with a conflict between what our personal goals dictate and what our tribe expects, we almost always default to the tribe's expectations. The reward of being accepted is universally deemed greater than the reward of winning an argument, looking smart, or finding the absolute truth.

Therefore, if a habit you want to build contradicts the norms of your immediate social circle, building it will feel like swimming upstream against a violent current. However, if your target habit aligns perfectly with your tribe's normal behavior, habit building becomes effortless.

1. Imitating the Close (Family and Friends)

Proximity is arguably the most powerful shaping force of human behavior. We pick up habits from the people around us through constant, daily exposure. You probably speak the same way as your parents, possess similar dietary preferences, and even mimic the vocal intonations of your best friends.

A landmark study examining tens of thousands of people over 32 years found that a person's chances of becoming obese increased by 57% if they had a friend who became obese. The reverse was also true: weight loss cascaded through social networks exactly like weight gain.

The Strategy: To build a better habit, join a culture where your desired behavior is the norm AND you already have something in common with the group. If you want to become a reader, join a book club of people in your industry or age bracket. The shared identity acts as the glue that secures your new habit.

2. Imitating the Many (The Tribe)

Whenever we are unsure of what to do, we look to the rest of the group to guide our behavior. This is social proof. When you browse Amazon, you buy the product with 5,000 five-star reviews because "the many" have validated it.

This instinct is phenomenally powerful. Clear details experiments by psychologist Solomon Asch where participants deliberately gave incorrect answers to an incredibly obvious question simply because everyone else in the room (who were secretly actors) gave the wrong answer.

The normal behavior of the tribe often overpowers the desired behavior of the individual. When changing habits means challenging the tribe, change is unattractive. When changing habits means fitting in with the tribe, change is highly attractive.

3. Imitating the Powerful (Status and Prestige)

Every society is hierarchically organized, and humans are obsessed with status. We are drawn towards behaviors that earn us respect, approval, admiration, and status.

Because we want the status that successful people have, we aggressively copy their habits. This is why thousands of people copy the morning routines of billionaires, buy the exact brands of clothing worn by celebrities, or adopt the communication styles of their favorite podcasters.

We are motivated to avoid behaviors that lower our status. We prune our hedges, iron our clothes, and use coasters because we want to maintain the perception of being competent and respected members of society.

Real-Life Examples

The Polgar Sisters

Clear tells the famous story of Laszlo Polgar, a Hungarian man who believed that geniuses are made, not born. He and his wife decided to completely immerse their three daughters in the world of chess from birth. Chess became the absolute norm of their household. The result? All three girls became world-renowned chess prodigies. Their environment made chess the most obvious, attractive, and normal behavior possible.

Nerd Fitness

Steve Kamb created Nerd Fitness to help people who identified as "nerds" get in shape. By combining fitness (the desired habit) with nerd culture (the shared identity), people who previously felt alienated by traditional gym bro-culture suddenly found a tribe where getting healthy was the norm.
