About this ebook
Have you ever noticed that what is exciting on Monday tends to become boring on Friday? Even passionate relationships, stimulating jobs, and breathtaking works of art lose their sparkle after a while. As easy as it is to stop noticing what is most wonderful in our lives, it’s also possible to stop noticing what is terrible. People get used to dirty air. They become unconcerned by their own misconduct, blind to inequality, and are more liable to believe misinformation than ever before.
Now, neuroscience professor Tali Sharot and Harvard law professor (and presidential advisor) Cass R. Sunstein investigate why we stop noticing both the great and not-so-great things around us and how to “dishabituate” at the office, in the bedroom, at the store, on social media, and in the voting booth.
This groundbreaking and “sensational guide to a more psychological rich life” (Angela Duckworth, New York Times bestselling author), based on decades of research, illuminates how we can reignite the sparks of joy, innovate, and recognize where improvements urgently need to be made. The key to this disruption—to seeing, feeling, and noticing again—is change. By temporarily changing your environment, changing the rules, changing the people you interact with—or even just stepping back and imagining change—you regain sensitivity, allowing you to identify more clearly the bad and more deeply appreciate the good.

A thousand things that had seemed unnatural and repulsive speedily became natural and ordinary to me. I suppose everything in existence takes its colour from the average hue of our surroundings.
—H. G. Wells¹
INTRODUCTION:
HOW WE HABITUATE TO EVERYTHING, ALL THE TIME
Habituation. It may be as fundamental a characteristic of life as DNA.
—VINCENT GASTON DETHIER¹
WHAT WAS THE BEST day of your life? You might find it difficult to select the very best day. That’s fine; just choose a really good day.
Some people think back to their wedding day. Others choose the day a child was born or their graduation day. Others give more idiosyncratic answers: The day I break-danced with my Labrador Retriever on the roof
or The day I gave a speech about the fear of public speaking.
As long as it was a great day, it qualifies.
Envision reliving that day. The sun is out; the sky is blue; you are running on the beach in your yellow bathing suit. Or maybe the sky is dark; the snow is falling; you warm your red nose against that of a newfound love. Whatever it is—it’s joyful. Now imagine reliving that day. Again. And again. And again. And again. You are trapped in a best day of my life
loop. What will happen?
What will happen is that the best day of your life will become less exciting, less joyful, less fun, and less meaningful. Soon the best day of your life will become tedious. The sun will not feel as warm, the snow not as magical, your love not so perfect, your accomplishments not as great, and your mentors not as wise.
What is thrilling on Monday becomes boring by Friday. We habituate, which means that we respond less and less to stimuli that repeat.²
That’s human nature. Even those things that you once found exhilarating (a relationship, a job, a song, a work of art) lose their sparkle after a while. Studies show that people even start habituating to the magic of a tropical vacation within forty-three hours of arrival.³
But what if you could restore your sense of amazement about those things that you no longer feel or notice? What if you could, to some extent, dishabituate?
That’s what this book is about. We will ask what could happen if people were able to overcome habituation in the office, in the bedroom, or on the athletic field. What would be the impact on happiness, relationships, work, community? And how would you go about doing that? We will see how temporarily changing your environment, changing the rules, changing the people with whom you interact, and taking real or imagined mini-breaks from ordinary life can help you regain sensitivity and start noticing what you barely see.
We won’t look only at how you can dishabituate to the best things, such as a terrific job, home, neighborhood, or relationship. We will also explore how you can dishabituate to the bad things. Now, you may think that is a dreadful idea. Why would you want to experience terrible things as if for the first time? If we made you experience the worst day of your life over and over and over, surely you would want a brain that habituates. You would want the pain of misery or heartache to weaken over time. That would be a blessing.
Fair enough, but here is the problem. When we habituate to the bad things, we are less motivated to strive for change. That Tuesday’s nightmare is Sunday’s snore becomes a serious challenge for fighting foolishness, cruelty, suffering, waste, corruption, discrimination, misinformation, and tyranny. Habituation to what is bad can lead us to take reckless financial risks, to fail to notice gradual changes in our children’s behavior that should raise concerns, to allow faint cracks in our romantic relationships to grow larger and larger, and to stop being bothered by stupidity or inefficiency at work.
So we will explore what happens when you habituate not only to the good, but also to the bad, and how to dishabituate. We will travel to Sweden, where switching the side of the road on which people drive led to a temporary decrease of approximately 40 percent in accidents, partly because of risk dishabituation.⁴
We will see how clean-air chambers may help people notice (and therefore care about) pollution, how stepping into someone else’s shoes can help us dishabituate to discrimination,⁵
and how taking breaks from social media can help you appreciate your life again.⁶
We will examine how looking at things anew, or from the side, can produce startling innovation.
But before we dive into all that, let’s consider why we are so quick to habituate to everything all the time. (Well, almost everything, and almost all the time. We’ll get to that.) We will consider why we have evolved a brain that is wired to want things (a fancy car, a big house, a loving spouse, a high-paying job), but then quick to overlook those things when we finally get them. We will ask why, despite being sophisticated creatures, we are relatively quick to accept dreadful things that become the norm, such as cruelty, corruption, and discrimination. To resolve these puzzles, we will use ideas and work from psychology, neuroscience, economics, and philosophy—some from our own research, some from others’.
Why are we quick to habituate? The answer is not that we are weak, ungrateful, or overwhelmed beings who do not appreciate threats and wonders. The answer has to do with a basic characteristic that we, two-legged, big-headed creatures, share with every other animal on earth, including apes, dogs, birds, frogs, fish, rats, and even bacteria.
HOW IT STARTED… WHERE IT’S GOING
More than 3 billion years ago, your ancestors appeared on earth.⁷
But you would not know it by looking at them. The resemblance is not apparent. They were smaller in size and less cultured. Fortunately, they were sophisticated enough to survive rough conditions. They did not have legs, but they could swim and tumble along in search of nutrient-rich environments. Yet even these primitive actions exhibited the hallmarks of habituation: when the level of nutrients in the environment was constant, your ancestors tumbled at a constant rate on a kind of autopilot. Only when the levels of nutrients changed did the frequency of their movements alter.⁸
Who were these early creatures? They were unicellular bacteria. As their name suggests, they were composed of only a single cell. In comparison, you have 37.2 trillion cells in your body.⁹
These cells interact, enabling you not only to swim and tumble, but also to run, jump, laugh, sing, and shout. But the behavior of even a single cell can habituate by inhibiting its own response.
Many years after unicellular organisms appeared on earth, simple multicellular organisms emerged. These organisms have neurons that can talk
to each other. The likelihood that they will talk changes over time. After one neuron sends an initial message to another neuron—perhaps a sensory neuron conveying information about a stinky odor to a motor neuron—it will often reduce the frequency of its signals even if the odor is still present.¹⁰
As a result, behavioral responses, such as movements away from that odor, reduce.
These processes happen in the human brain too. This is one reason you may stop noticing the smell of tobacco after a few minutes in a smoke-filled room, and why you might be amazed to find yourself getting used to background noise that, at first, greatly irritated you.
To demonstrate this basic principle, let us go back in time to Vienna, Austria, in 1804. A twenty-four-year-old Swiss physician, Ignaz Paul Vital Troxler, was studying vision when he made an astonishing discovery.¹¹
He noticed that if he fixed his eyes on an image for long enough at close distance, it seemed to disappear. Try it yourself. Locate the colorful round image on the flap of the cover of this book (it is a circle with a black point in its center). Fix your eyes on the black cross without moving them for about thirty seconds. The colorful clouds will soon disappear and turn into gray nothingness.
This happens because your brain stops responding to things that don’t change.I
Once you move your eyes, you will immediately regain awareness of the colors. You see them again. By moving your eyes, you are changing the inputs your brain receives. Of course, it’s not only constant rainbow clouds that your brain stops noticing. Over time, you stop feeling the socks on your feet or hearing the persistent buzz of an air conditioner.¹²
(Perhaps you aren’t noticing some background noise right now?)
You get used to much more complex circumstances too (such as wealth, poverty, power, risk, marriage, and discrimination), and this type of habituation involves active inhibition between different neurons.¹³
For example, imagine that your neighbor, Ms. Wheeler, got a new dog, a German Shepherd named Finley. Finley barks a lot. At first the barks are surprising; you notice each one. But after a while your brain creates a model
(that is an internal representation) of the situation (Whenever I pass by Ms. Wheeler’s house, Finley will bark
).¹⁴
You anticipate the bark. When you experience it (Finley barks
), your brain compares the experience to the model (Whenever I pass by Ms. Wheeler’s house, Finley will bark
). If the experience matches the model, your response (neural, emotional, behavioral) is inhibited.
With more and more experiences of Finley barking, your internal model becomes increasingly precise and will better match the actual experience of hearing Finley bark. The better the match, the more your response is inhibited. But if the match is not identical (for example, the dog sounds louder, softer, or angrier, or jumps over the fence and runs in your direction), you will be surprised, and your response will be less inhibited.
Let’s try this ourselves. Look at the photo below.
If you are like most people, you were probably startled by the photo at first. You might have felt uneasy, disgusted, or even afraid for a second or two. But as long as the dog does not jump off the page and sink its sharp teeth into your smooth neck, your brain will respond less and less to its raised lips and raging eyes.¹⁵
As a result, the uneasy feeling will eventually disappear. You have become habituated. (Something similar happens if you encounter someone with an unusual physical appearance. At first, you will notice it and perhaps be preoccupied by it; after a while, you might be startled to see that it barely registers.)
Your brain seems to have evolved different mechanisms, from those involving a single cell to those involving more complex neural systems, that obey the same overarching principle. The principle is simple: when something surprising or unexpected happens, your brain will respond strongly. But when everything is predictable, your brain will respond less, and sometimes not at all. Like the front page of a daily newspaper, your brain cares about what recently changed, not about what remained the same. This is because to survive, your brain must prioritize what is new and different: the sudden smell of smoke, a ravenous lion running your way, or an attractive potential mate passing by. To make the new and unexpected stand out, your brain filters out the old and expected.
In the chapters that follow, we will see how knowledge of how your brain works can help you to identify ways to revel in the good things to which you have habituated, so that phenomenal features of your life may resparkle,
as well as ways to focus on, and seek to change, the bad things you no longer notice, including your own bad habits. We will consider health, safety, and the environment, exploring how you can perceive serious risks to which you have become accustomed. We will show how becoming aware that your brain responds less to repeated stimuli can help make you resilient in the face of repetitive misinformation from others and help you address the chronic stress and distraction that social media triggers. We will show how habituation and dishabituation offer lessons for business—about what keeps employees motivated and customers engaged. We will also consider how people get used to gender and racial discrimination and even to the gradual rise of fascism, until dishabituation entrepreneurs
—rebels who combat the norms—make them salient.
All that being said, habituation is crucial for survival: it helps us adapt quickly to our environment. When people are unable to habituate (for example, to physical pain), that inability can cause great suffering. Some people are also less likely to habituate than others. We will see how slow habituation can lead to a range of mental health problems, but also to creative insight and extraordinary innovation (in business, sports, and the arts).
We hope that what follows will help you turn off the brain’s gray scale, to see colors again.

HAPPINESS:
ON ICE CREAM, THE MIDLIFE CRISIS, AND MONOGAMY
If I was here for the last eighteen years doing that all day, every day, it probably wouldn’t still have pixie dust on it. But I go away, and I miss it so much. Then I come back, and it kind of resparkles.
—JULIA¹
MEET JULIA AND RACHEL. Both women are living what many would consider charmed lives. They are in their midfifties; Julia lives in New Mexico and Rachel in Arizona. The two women have loving partners. Julia has three adorable children—two sons and one daughter. Rachel has two daughters. They both have fulfilling jobs they excel at, which have made them wealthy. They are also fit and healthy. Many people would say they have been, well, blessed.
But here the similarities end. While in many ways both women won life’s lottery, their subjective experience is quite different. Julia marvels at her good fortune on most days, but Rachel has become blind to her fairy-tale existence.
Julia is in awe of the miracles in her life, big and small. She says she has a happy life.
When asked about her ideal day, she says, When there’s harmony in the house and you get up and make breakfast and see everybody off to school. Then do some adventuring with my husband. We’ll take a bike ride or have a coffee or a meal somewhere, and then I’ll have time to myself and now it’s almost three o’clock. I’ll go get the kids from school. Lacrosse practice. Start making dinner.
²
Rachel has a word for such days: Boring!
Sure, she is aware that she has been blessed with family, wealth, health, and friends. She is not sad or depressed, but she does not experience her daily life as happy.
She says, It’s okay.
What crucial ingredient separates Julia from Rachel? It is not a personality trait or genetics. It is not the quality of their relationships with family and friends. The difference is small but significant. Julia travels for work often; she goes away for a few days, maybe weeks, and comes back home. She says, I go away, and I miss it so much. Then I come back, and it kind of resparkles.
Being away allows her to focus on the joy of the details of life.
She says: If I was here for the last eighteen years doing that all day, every day, it probably wouldn’t still have pixie dust on it.
³
Rachel does not get to take frequent breaks from daily life, and as a result she doesn’t perceive the pixie dust that covers her world. She does not get to experience life without her husband, children, and comfortable home. Instead, those things are there, in front of her, every single day. As a result, they accumulate dust and lose their sparkle.
We have a secret to share: you’ve probably heard of Julia before. You might have spent time with her in your living room, eating popcorn in your pajamas. Julia is Julia Roberts, the celebrated actress (and the quotations are real). We know what you are thinking: Of course, Julia Roberts is joyful and grateful. Could there be a more privileged person?!
But in this case, we think that Julia’s observations about her unusually privileged life can shed light on ordinary human experience. And we believe it may offer insight into how all of our lives can resparkle.
Now, while you have not heard of Rachel before (she is an acquaintance whose identifying details we have altered), you probably know someone who resembles her. In many ways she represents the lived reality of many people. She reflects the daily experience of many of us who might not have what Rachel has, but who do have precious things in our lives (perhaps a loving family, perhaps good friends, perhaps an interesting job, perhaps a talent) and tend not to focus much on those things, at least not from moment to moment or from day to day.
What might seem amazing to others, or what was once amazing to us, becomes part of life’s furniture. We habituate to it. For example, studies show that after getting married, people report being happier on average. Yet, after about two years of this joyful honeymoon period, happiness levels tend to decline to premarriage levels.⁴
So let’s try to understand why people such as Rachel stop seeing and appreciating the good things in their lives, and how Rachel can adopt a Julia perspective. Without becoming a Hollywood star with a stunning smile, that is.
ICE CREAM EVERY DAY
On a recent hike up the mountains in California, Tali and her then nine-year-old daughter, Livia, stumbled upon a gorgeous mansion on a cliff overlooking the ocean. Envision those stunning European mansions in old movies where Grace Kelly’s characters find themselves. (Julia might live there now.) After gasping, Tali asked her daughter if she would like to live in such a mansion.
No!
said Livia.
Why not?
asked Tali.
Well, whenever I get ice cream or a toy, it is a treat, and it makes me very happy. But if you are that rich, you get ice cream and toys all the time and so you don’t appreciate it because you get it every day. It stops being a treat and you are not grateful.
Livia’s point is well-taken. It is echoed by more mature thinkers. The economist Tibor Scitovsky, for example, said that pleasure results from incomplete and intermittent satisfaction of desires. This claim is worth repeating—pleasure results from incomplete and intermittent satisfaction of desires.⁵
That means that the good things in life (whatever your fancy—amazing food, great sex, expensive cars) will trigger a burst of joy if you experience them occasionally. But once those experiences become frequent, daily perhaps, they stop producing real pleasure. Instead, they produce comfort. Scitovsky
