We’re scratching the surface in this Nudge summary. If you don’t already have Richard H. Thaler and Cass R. Sunstein’s popular book on economics, psychology, and business, order it here or get the audiobook for free to learn the juicy details.
Do we make our own choices? Or do external factors influence our decisions at almost every level in life? Nudge explains how human choices result from certain behavioral economic factors.
The book explores why people choose the path with the least friction in decision-making. It also details how states and organizations use nudges to influence people’s choices. This includes health, wealth, and happiness decisions. In the end, Nudge sheds light on the bias that creeps into the decision-making process.
Let Nudge be your guide in understanding how smaller decisions influence your behavior. This book isn’t about denying freedom of choice. Rather, it introduces the concept of “libertarian paternalism.”
You’ll learn about behavioral economics and how to identify, analyze, and control nudges. Discover how the principles in Nudge can improve your life by enhancing your decision-making skills.

About Richard H. Thaler and Cass R. Sunstein
Richard H. Thaler is a behavioral science and economics professor at the University of Chicago. Nudge and Misbehaving: The Making of Behavioral Economics are among his bestselling books. He won the Nobel Prize in Economics and is widely praised for his work in behavioral economics. He’s also featured in many publications and the blockbuster film, The Big Short.
His co-author, Cass R. Sunstein, founded Harvard Law School’s Behavioral Economics program. He is also a professor at the University of Chicago and an author of renowned books like How Change Happens. From 2009 to 2012, Sunstein served in the Obama administration. He worked in the Office of Information and Regulatory Affairs as an administrator.
Thaler and Sunstein came up with Nudge at the University of Chicago. The idea was to show how states and organizations use nudges to influence people’s lives. They also wanted to prove humans need some form of influence to live their best lives. To this end, here’s a summary of ten key insights they discussed in the book:
StoryShot #1: Humans Think Using Two Cognitive Systems
The common belief is that most humans are capable of making sound decisions to better their lives. Yet, many people make poor judgments daily. This is often due to emotions, cognitive flaws, and lack of information. Famous psychologist Daniel Kahneman simplifies the reason humans make bad decisions. He says it is often down to two critical cognitive systems.
1. Reflective thinking – This refers to slow, effortful, and deliberate thinking. Humans apply it when solving life’s complex problems. For example, reflective thinking occurs when learning a new skill. But, once certain acts become a habit, thinking changes from reflective to automatic.
2. Automatic thinking – This refers to fast, effortless thinking. Humans use it in making daily decisions. It often takes over when our actions become natural due to memory, information, or bias. For example, dressing becomes an act of automatic thinking once you become used to it. Automatic thinking helps people make split-second decisions. It also leads them to make bad decisions.
StoryShot #2: There are Six Key Nudges
Nudge introduces four main nudges: anchoring, availability, repetition, and status quo. It explains how behavioral economics influences the choices humans make in life. It also explores specific heuristics or nudges and their influence over human decisions. We also learn how these nudges are responsible for poor decisions humans make.
Here are the main nudges and their influence over humans:
Anchoring refers to making adjustments to making decisions based on perceived facts. For example, if someone asked you, what is the population of Chicago? If you live in Milwaukee, your guess would be that Chicago has more people. This is because of the “fact” that Chicago is more significant than Milwaukee.
The act of tying down decisions to specific facts (anchors) is anchoring. While anchors are great for problem-solving, they can also lead us to make poor choices. Like in the example above, some states are smaller but have a larger population than others. For example, Rhode Island is smaller but has a bigger population than Alaska and Wyoming.
Availability refers to making decisions based on what you’re thinking about right now. For example, you may buy a gun based on a recent report on increased insecurity in your area. In this case, you’ve decided based on the “available” information.
By putting the availability bias to good use, we can make better decisions for everyone. Still, decisions based on the available information can also backfire. Like the case above, purchasing a gun doesn’t always mean being safer. Guns contribute to more suicides than homicides in America. Thus, buying one endangers you and your family rather than protects them.
Repetitiveness bias is where people decide based on similar experiences. For example, most people will judge two products, A and B, based on their prior experiences with them.
Like anchoring and availability, repetitiveness helps but also carries a risk. Only some experiences show how the future will be since things change. And even if an experience repeats itself, the outcome could be different.
Status quo refers to making a decision and failing to take action to avert the consequences of it later. It is also called the doing nothing or default bias. This nudge affects people who are too lazy or busy to choose at a particular time.
Imagine you sign up for a free trial of a streaming service but forget to cancel it before it converts into a paid subscription. As a result, your credit card gets billed for the full subscription automatically.
In this example, the status quo is your initial decision to sign up and not cancel the trial in time. Failing to take action to prevent the consequences (getting billed), you’ve succumbed to the default bias or doing nothing approach. This nudge affects individuals who are too lazy or busy to make a conscious choice at the right moment.
The prospect of losing scares most people more than the excitement of gaining. Nudge explains how the fear of loss influences human decisions. When people are afraid to lose something, they’d rather not take a risk and win than take and lose. For example, when gambling, most people fear losing $200 more than gaining $1000. For this reason, they often choose not to make a bet.
As with all nudges, the loss aversion bias can lead humans to make good and bad decisions. For example, in the case above, not making that bet might save finances and prevent loss now. But, it could also result in massive winnings.
Optimism and Overconfidence
Optimism and overconfidence are powerful nudges in human life. They can influence both positive and negative choices. Unrealistic optimism causes people to overestimate or underestimate the rewards of their decisions. For example, someone might want to go on vacation but never save or control their spending. Such a person has an unrealistic optimism that might never come true. When people overestimate or underestimate the rewards of decisions, they make mistakes. As a result, they end up at a worse point than they were.
Other minor yet impactful nudges worth mentioning from this book include:
- Framing (positioning questions to suggest something)
- Temptation (ego, greed, short-term rewards)
- Spotlight Effect (anxiety, fear for all eyes on me)
- Priming (preparing people to decide)
- Sensory Experiences (sounds/music, touch, smell, color)
While these are minor nudges, they all impact the human decision-making process in a way.
StoryShot #3: People Make Decisions Based on Options Presented to Them
Decisions are influenced by our environments and the options we have at the time. The way in which options are presented to us, including their form, style, and sequence, has a significant impact on our decision-making process. We refer to this as “choice architecture,” which encompasses the environment and the order in which options are presented to humans. Choice architects are entities that design the environment and options presented to us. As human beings, we are the principal choice architects of our lives. We can design our environments and create nudges to make the best decision possible.
Still, states and organizations are principal choice architects in people’s decisions. Most of them design environments for their people to make sound decisions.
For example, car manufacturers install alarms to prompt anyone inside to wear a seat belt. This nudge appears every time after entering a vehicle to prevent us from forgetting. The same applies to dangerous products like tobacco. The government nudges people to avoid harmful products. It does this by explaining the health risks in ads or on the product itself.
Although good-choice architects are helpful, others use them for their selfish gain. Some organizations and governments nudge people toward biased choices for personal gain.
StoryShot #4: Humans Need Nudges to Improve Their Financial Life
Humans often make the wrong financial choices. The world is full of people with regrets due to bad money choices. Most people make poor decisions on spending, debt management, retirement plans, and investing. Governments and financial organizations use various nudges to help society use money better. Some of the financial nudges humans receive to better their lives include:
- Retirement nudge: Most people would choose not to save for retirement if asked. This is because of the complexity of the entire savings system. So the government introduced several plan options, including the default option. This makes it easier for people now to plan their retirement.
- Debt nudge: Humans love debt. Most people would be in debt if financial institutions gave out free credit cards. As such, financial institutions set certain thresholds to control borrowing. This way, people can only take what they can afford to pay. An excellent example of this is the FICO score. It limits the number of people who can get loans.
- Insurance nudge: Problems often come at the most unexpected times. Insurance firms use advertisements, billboards, and brochures to show the consequences and benefits. This nudge influences more people to take emergency insurance policies.
- Investment nudge: Poor investment decisions can lead to losses. Most people don’t know where or when to invest their money. Humans can even invest in overvalued stocks because everyone else is doing it. Organizations offer transparent investment plans with the returns and risks outlined. They do this to nudge people to take up the right plans.
Finances are a tricky part of people’s lives. So, financial institutions and governments help people manage their money better by giving them nudges.
We rate Nudge 3.9/5.
