Book Depository: The Power of Habit by Charles Duhigg

Charles Duhigg’s book creaks under the examples he throws at the wall to support any observation. They are wearisome after a while. This book could have been stated just as effectively as a pamphlet, so here it is.


The habit loop is what happens when a sensory trigger precipitates a routine, which then leads to a reward of some kind. Over time, neural connections that link the trigger to the routine are strengthened in anticipation of the next reward, until the routine happens without conscious thought. Animals can be trained to follow surprisingly complex routines by exploiting the habit loop.

A keystone habit is a single change introduced into a daily routine. It exploits the habit loop to precipitate a small change. The reward from this can be used to power ever-larger changes.

Putting a piece of fruit on your desk to trigger a health regime, so you don’t go searching for snacks, is a simple example. Keeping a register of things you eat is another. At the company level, as Paul O’Neill did with Alcoa, you might be able to focus the organisation on one goal because that goal necessitates other changes you want to see. In the case of Alcoa, the goal was zero accidents. This required transformations in the chain of command and in industrial processes that enabled Alcoa to become much more successful and less wasteful, without these being explicit goals.

Exploit the habit loop when you can. Reduce the change you want into one keystone habit, or to improve one metric, or to make one difference.

In the long term, self-discipline has more influence on long-term success than intellectual ability. Willpower is like a muscle:

  1. It develops and improves with practice;
  2. It can tire through overuse, leading to a speculative explanation for high-flying businessmen and senior politicians regularly making spectacularly poor decisions in their personal lives.
  3. You can burn it out altogether for a while, after which it’s weakened and slowly recovers.

Willpower, like habit, is fed through positive reinforcement. It requires a personal reason for applying it to complete the habit loop. Any kind of reward will suffice, but you need a carrot even if you already have a stick.

Willpower is vulnerable to pressure. To form new habits under hard conditions, train with those conditions in mind. Rehearse particularly stressful encounters or difficult situations that upset you. Plan for when you struggle with willpower and replay successful scenarios like videos in your mind’s eye. They will become a better habit.

Starbucks sees its service as more important than the quality of its coffee. It trains employees, some of whom have anger problems, using the LATTE method (listen; acknowledge; take action; thank the customer; explain). This serves a social purpose too. Using this method, staff write a plan about how they’ll deal with an abusive customer, and it helps them to maintain their professionalism under fire.

In An Evolutionary Theory of Economic Change (Nelson and Winter), the case is made that companies aren’t families, but battlefields in a civil war. A functional equilibrium is established with a network of truces between ambitious people. These may work when it’s business as usual to the extent that they’re impossible to change. However, they are too rigid for organisational improvement, and may break down entirely in a crisis. Disaster is then inevitable. The 1987 King’s Cross fire, and the Fennell Report after it, illustrates a dysfunctional organisation in a crisis, and a way to transform it. Desmond Fennell fanned a media circus and allowed people to be shamed in public. It can be worth stirring up a catastrophe rather than letting it die down because, when people are vulnerable, it is rare opportunity to face failure, make changes, and establish new rules and habits.

Some social movements succeed while others fail. Three things are needed: friendships between individuals, a community with specific, identifiable interests, and leadership that is able to divest power to the ranks as it inspires. Rosa Parks, The Montgomery bus boycott and Martin Luther King are the archetypical example. Rosa Parks was not the first black woman to be arrested on a bus, but her high social standing, combined with a creeping awareness of the Civil Rights movements, was enough to trigger change. Leadership of such a movement has to be able to establish a strong culture, and then stand back so that it can be owned and led by its people.

If you can include a core of religious faith, as the Civil Rights movement did, and as Alcoholics Anonymous does, you provide a stronger way of displacing destructive cycles of habit with helpful, community-focused ones.

Weak ties, soft power, and peer pressure are how individuals advance themselves. Weak ties are acquaintances and friends of friends: these networks get people their next job or their customers. Soft power is power that influences rather than coerces: the kind that makes you attend an event because you think that certain people will expect you to.
