The Science of Happiness
Psychology explores humans at their best.
This doesnt feel like a normal academic conference. True, the three-day Positive Psychology Summit is a sellout, with 425 attendees thronging the meeting rooms in downtown Washington, D.C. But despite the familiar trappings, something seems different. Theres herbal tea available at breaks, and the conferences organizer, Shane Lopez of the University of Kansas, walks around smiling and ringing a dinner bell to prompt people to take their seats for the next session. This group is slimmer, healthier, younger, and more female than the usual scholarly crowd. Some stretch in yoga-like postures in the aisles, or recline on friends bodies as if resting on a chaise longue. The professional jargon includes recurring words like flow, optimism, resilience, courage, virtues, energy, flourishing, strengths, happiness, curiosity, meaning, subjective well-being, forgiveness, and even joy.
But the main difference probably shows up in the question periods. Typically, academics seem obsessed with poking holes in the argument of the presentation just madefinding fault, pointing out counter-examples, insisting on qualificationswith the transparent purpose of one-upping the speaker. Such shenanigans are absent here. Theyre trying to build, explains one participant. Theres none of this academic carping, observes professor of psychiatry George Vaillant, who has spoken at five of these summit events. The teaching exercises Ive done for positive psychology audiences have been an absolute joy. Here, people really laugh at the jokes.
This October morning, they are laughing with Tal Ben-Shahar 96, Ph.D. 04, an associate of the Harvard psychology department, who argues in his opening keynote address that positive psychologists need to build bridges between the ivory tower and Main Street, to unite academic rigor with the accessibility of popular psychology books. Most people do not read the Journal of Personality and Social Psychology, he notes. In fact, one of my colleagues at Harvard did a study, and he estimated that the average journal article is read by seven people. And that includes the authors mother.

Ben-Shahar is a psychologist and author who has never pursued a tenure-track position nor published research in professional journals (even so, his third book, Happier: Finding Meaning, Pleasure, and the Ultimate Currency, is due this spring). Ben-Shahars passion is teaching, and he goes on to explain how he teaches positive psychology. His Harvard course on the subject has been offered twice, in 2004 and in 2006, when its enrollment of 854 students was the largest of any course in the catalog, surpassing even introductory economics. This startling fact seized the attention of national media, and pieces about Happiness 101 (actually, Psychology 1504, Positive Psychology) appeared in the Boston Globe and on CNN, CBS, National Public Radio, and overseas in the Guardian, the Jerusalem Post, and the Shanghai Evening Post, making Ben-Shahar one of the best-known positive psychologists alive. At 36 years of age, he is a young star in a field that is only eight years old.
For much of its history, psychology has seemed obsessed with human failings and pathology. The very idea of psychotherapy, first formalized by Freud, rests on a view of human beings as troubled creatures in need of repair. Freud himself was profoundly pessimistic about human nature, which he felt was governed by deep, dark drives that we could only tenuously control. The behaviorists who followed developed a model of human life that seemed to many mechanistic if not robotic: humans were passive beings mercilessly shaped by the stimuli and the contingent rewards and punishments that surrounded them.
After World War II, psychologists tried to explain how so many ordinary citizens could have acquiesced in fascism, and did work epitomized in the 1950 classic The Authoritarian Personality by T.W. Adorno, et al. Social psychologists followed on, demonstrating in laboratories how malleable people are. Some of the most famous experiments proved that normal folk could become coldly insensitive to suffering when obeying legitimate orders or cruelly sadistic when playing the role of prison guard. Research funders invested in subjects like conformity, neurosis, and depression.
A watershed moment arrived in 1998, when University of Pennsylvania psychologist Martin Seligman, in his presidential address to the American Psychological Association, urged psychology to turn toward understanding and building the human strengths to complement our emphasis on healing damage. That speech launched todays positive psychology movement. When I met Marty Seligman [in 1977], he was the worlds leading scholar on learned helplessness and depression, says Vaillant. He became the worlds leading scholar on optimism.
Though not denying humanitys flaws, the new tack of positive psychologists recommends focusing on peoples strengths and virtues as a point of departure. Rather than analyze the psychopathology underlying alcoholism, for example, positive psychologists might study the resilience of those who have managed a successful recoveryfor example, through Alcoholics Anonymous. Instead of viewing religion as a delusion and a crutch, as did Freud, they might identify the mechanisms through which a spiritual practice like meditation enhances mental and physical health. Their lab experiments might seek to define not the conditions that induce depraved behavior, but those that foster generosity, courage, creativity, and laughter.
Seligmans idea quickly caught on. The Gallup Organization founded the Gallup Positive Psychology Institute to sponsor scholarly work in the field. In 1999, 60 scholars gathered for the first Gallup Positive Psychology Summit; two years later, the conference went international, and ever since has drawn about 400 attendees (the maximum for the meeting space, Gallups world headquarters) annually. The October conference-goers represented 28 countries, 70 businesses or foundations, and 140 educational institutions.
Teaching has mushroomed, too. In 1999, the late Philip J. Stone, professor of psychology at Harvard, taught a positive psychology course to 20 undergraduates. There were hardly any college courses on the subject then; seven years later, there are more than 200 across the United States. The University of Pennsylvania offers a masters degree in the field. International growth, too, is strong. Recently, Ben-Shahar gave seminars in China on the relationship of positive psychology to leadership, and he says interest from Chinese educators and media was huge.
The fields roots go back at least to 1962, when Brandeis psychologist Abraham Maslow wrote about what a human life could be at its greatest in Toward a Psychology of Being. His humanistic psychology became the disciplines third force, following psychoanalysis and behaviorism. The fundamental difference between humanistic psychology and positive psychology is in their relationship to research, epistemology, and methodology, says Ben-Shahar. Many who joined the Third Wave were not rigorous. Humanistic psychology gave birth to the self-help movement, and lots of self-help books have come out with concepts grounded in emotion and intuition. Positive psychology combines those things with reason and research.
Doing so apparently answers needs the first and second forces have left unsatisfied. Im in a department of psychiatry, and psychiatry does not have a good model of mental health, says clinical instructor in psychology Nancy Etcoff, who is based at Massachusetts General Hospital (MGH). Is there a model of mental health beyond no mental disease? Vaillant, a psychiatrist and a trained psychoanalyst, says, As a psychoanalyst, Im paid to help you focus on your resentments and help you to find fault with your parents. And secondly, to get you to focus on your poor-mes and to use up Kleenex as fast as possible. He recalls visiting, as a medical student, the most famous teaching analyst at Harvard and asking him if he knew of any case history in which psychoanalysis had worked. Yes, the great man said, after a moments thought. Why, just recently, a former patient of mine referred her 18-year-old daughter to me.
Vaillant notes that the Comprehensive Textbook of Psychiatry, the clinical bible of psychiatry and clinical psychology, has 500,000 lines of text. There are thousands of lines on anxiety and depression, and hundreds of lines on terror, shame, guilt, anger, and fear. But there are only five lines on hope, one line on joy, and not a single line on compassion, forgiveness, or love. Everything Ive been taught encouraged me to focus on the painful emotions, because people cant do that themselves. My discipline taught me that positive thinking was simply denial, and that Pangloss and Pollyanna should be taken out and shot. But working with peoples strengths instead of their weaknesses made a difference. Psychoanalysis doesnt get anybody sober. AA [Alcoholics Anonymous] gets people sober.
Effective psychological interventions like AA are in acute demand nowadays. There is an epidemic of depression in every industrialized nation in the world, declared Seligman at the 2006 positive psychology summit. Its a paradox; the wealthier we get, the more depressed young people get. Richard Kadison, chief of mental health at the Harvard University Health Services, writing in the New England Journal of Medicine in 2005, cited a national survey of 13,500 college students which found that 45 percent reported feeling depression deep enough to prevent them from functioning, and 94 percent felt overwhelmed by everything they had to do. In our time, depression is on the rise, Ben-Shahar says. More and more students experience stress, anxiety, unhappiness. Until a few years ago, we didnt have e-mail; now, students check their e-mail 20 times a day. Students work longer hours and are having to build up their résumés to levels that, 20 years ago, were not expected of young people. Students today are looking for ideas that will help them to lead better lives.
Such ideas affect not only psychological states, but economics and culture. Our world has been run according to neoclassical economics, said Gallups longtime chairman and CEO, Jim Clifton, at the fall summit. We squeezed every drop out of that rockdata and equationsand that got maxed out. The world has gotten so much more competitive and now, you need so much more. Edward Deming went to Japan and then the world put Total Quality Management on top of classical economics. Now thats maxed out. The next wave will be behavioral economics and cognitive economicspositive psychology, well-being, strengths science. Im betting my job and this company on it. We are in it for keeps.
Despite abundant evidence arguing for building success on ones personal strengths, about 75 percent of respondents in surveys say that working on ones weaknesses is more important than fostering strengths. This may be because human beings are very sensitive to danger or pain, says Nancy Etcoff. Our taste buds respond more strongly to bitter tastes than to sweet ones. That might help us to avoid poison. Etcoff, an evolutionary psychologist, studies how natural selection may have shaped not only our bodies, but our psychological dispositions. Extending the sweet/bitter argument to relationships, she mentions research showing that, unlike couples destined for divorce, spouses in successful marriages have a five-to-one ratio of positive-to-negative gestures when they argue.
We start with a mild tendency to approach [others], Etcoff continues. But when we encounter something negative, we pay extraordinary attention to it. Think about hearing a description of a stranger: Joe is happy, confident, and funny. But hes cheap. Negative information like this can forecast a problem: if Joe is cheap he may hoard, rather than share his resources with us. Our emotions are like a smoke detector: its OK if they sometimes give a false signal, Etcoff says. You dont die from a false positive. Its better to be too sensitive. We evolved in a world of much more immediate dangergerms, predators, crevasses.
Etcoffs 1999 book, Survival of the Prettiest, argued that our attraction to beauty, and beauty itself, were evolutionary outcomes of natural selection. One big question was, Are beautiful people happier? Etcoff says. Surprisingly, the answer is no! This got me thinking about happiness and what makes people happy. Etcoff, who directs the Center for Aesthetics and Well-Being at MGH, explored hedonicsthe science of pleasure and happinessto find out how scholars have measured happiness. (In mood surveys, at any random moment, around 70 percent of people say they are feeling OK, Etcoff says.)
Nobel Prize-winning psychologist and behavioral economist Daniel Kahneman of Princeton (see The Marketplace of Perceptions, March-April 2006, page 50) asked thousands of subjects to keep diaries of episodes during a dayincluding feelings, activities, companions, and placesand then identified some correlates of happiness. Commuting to work was way down therepeople are in a terrible mood when they commute, Etcoff says. Sleep has an enormous effect. If you dont sleep well, you feel bad. TV watching is just OK, and time spent with the kids is actually low on the mood chart. Having intimate relations topped the list of positives, followed by socializingtestimony to how important the need to belong is to human satisfaction. Etcoff applied these methods to 54 women, in a study sponsored by the Society of American Florists, and found that an intervention as simple as a gift of flowers that stayed in ones home for a few days could affect a wide variety of emotionsfor example, less anxiety and depression at home and enhanced relaxation, energy, and compassion at work.
Environs, too, affect mood. Settings that combine prospect and refuge, for example, seem to support a sense of well-being. People like to be on a hill, where they can see a landscape. And they like somewhere to go where they can not be seen themselves, Etcoff explains. Thats a place desirable to a predator who wants to avoid becoming prey. Other attractive features include a source of water (streams for beauty and slaking thirst), low-canopy trees (shade, protection), and animals (proof of habitability). Humans prefer this to deserts or man-made environments, Etcoff says. Building windowless, nature-less, isolated offices full of cubicles ignores what people actually want. A study of patients hospitalized for gall-bladder surgery compared those whose rooms looked out on a park with those facing a brick wall. The park-view patients used less pain medication, had shorter stays, and complained less to their nurses. We ignore our nature at our own peril.
Etcoffs next book, on happiness and evolution, will attempt to deconstruct happiness itself, distinguishing between concepts like pleasure and desire, or euphoria and craving. Our reward system is fed by [the neurotransmitter] dopamine that is thought to activate the brains pleasure centers, Etcoff says. It is really a brain desire systemits really about wanting. You see all these pleasures, but which ones do you really want? People like good-looking faces, but that doesnt mean they desire them. Pleasure and pain are related in the brain, through the opioid neurotransmitters that produce a feeling of comfort. The opioid system triggers pleasure. Sugar, which recalls the sweetness of mothers milk, can set it off. Caressing, sex, fatty foods, sunlight on the skinall these can do it, too.
We evolved in a much different world, with much less choice and no sedentary people, Etcoff continues. We didnt evolve for happiness, we evolved for survival and reproduction. For this reason, we are sensitive to danger. Pleasure and the positive-reward system is for opportunity and gain, Etcoff explains. And pleasure involves risk, taking a chance that can override some of your fear at that moment.
Like reaching for joy. Mammalian evolution has hard-wired the brain for spiritual experience, said George Vaillant at the 2006 summit, and the most dramatic spiritual experience is joy. Developmentally, the childs smile, the kittens purr, and the puppys wagging tail emerge at the same time. These social responses are elicited by, and in turn elicit, positive emotion. They all occur when the infant brains more primitive limbic system becomes effectively wired to the forebrain.
Negative emotions, like aggression and fear, are as developed in lower animals as in humans. But the limbic system differentiates mammals from reptiles, and contains most of what we know of positive emotions and spirituality, Vaillant argued. Negative emotions help us to survive individually; positive emotions help the community to survive. Joy, unlike happiness, is not all about mejoy is connection. Beethoven knew little happiness, but he knew joy. The mystics have linked joy to connection with a power greater than themselves.
Happiness activates the sympathetic nervous system (which stimulates the flight or fight response), whereas joy stimulates the parasympathetic nervous system (controlling rest and digest functions). We can laugh from either joy or happiness, Vaillant said. We weep only from grief or joy. Happiness displaces pain, but joy embraces it: Without the pain of farewell, there is no joy of reunion, he asserted. Without the pain of captivity, we dont experience the joy of freedom.
Yet there is far more research on happiness than on joy, the least-studied emotion, according to Vaillant, whose next books working title is Faith, Hope, and Joy: The Neurobiology of Positive Emotion. For the last 20 years, emotion has been an unwelcome guest at the table of scholarship, he says. We treat joy as secret, dirty, and awful, the way the Victorians treated sex. Happiness is largely cognitive; its a state of mind, not an emotion. Thats why social scientists and economists love to study happiness. Happiness is tame.
Dont call Daniel Gilbert a positive psychologist. He isnt one, and doesnt approve of the label, although he doesnt quarrel with the research. I just dont see what the parade is for, he says. I dont think psychology needs a movement; movements are almost always counter-productive. By including some people and filling them with irrational exuberance, they divide the field. Positive psychology doesnt cut psychology at the joint. I wouldnt condemn the work or ideas; probably 85 percent of the ideas are worthless, but thats true everywhere in science.
That said, Gilbert, a professor of psychology, shares a lot of subject matter with the positive psychologists. His book Stumbling on Happiness became a national bestseller last summer. Its central focus is prospectionthe ability to look into the future and discover what will make us happy. The bad news is that humans arent very skilled at such predictions; the good news is that we are much better than we realize at adapting to whatever life sends us.

Is happiness elusive? Gilbert asks. Well, of course we dont get as much of it as we want. But were not supposed to be happy all the time. We want that, but nature designed us to have emotions for a reason. Emotions are a primitive signaling system. Theyre how your brain tells you if youre doing things that enhanceor diminishyour survival chances. What good is a compass if its always stuck on north? It must be able to fluctuate. Youre supposed to be moving through these emotional states. If someone offers you a pill that makes you happy 100 percent of the time, you should run fast in the other direction. Its not good to feel happy in a dark alley at night. Happiness is a noun, so we think its something we can own. But happiness is a place to visit, not a place to live. Its like the childs idea that if you drive far and fast enough you can get to the horizonno, the horizons not a place you get to.
Gilbert reconsiders his grandmothers advice on how to live happily ever after: Find a nice girl, have children, settle down. Research shows, he says, that the first idea works: married people are happier, healthier, live longer, are richer per capita, and have more sex than single people. But having children has only a small effect on happiness, and it is a negative one, he explains. People report being least happy when their children are toddlers and adolescents, the ages when kids require the most from the parents. As far as settling down to make a livingwell, if money moves you into the middle class, buying food, warmth, and dental treatmentyes, it makes you happier. The difference between an annual income of $5,000 and one of $50,000 is dramatic, Gilbert says. But going from $50,000 to $50 million will not dramatically affect happiness. Its like eating pancakes: the first one is delicious, the second one is good, the third OK. By the fifth pancake, youre at a point where an infinite number more pancakes will not satisfy you to any greater degree. But no one stops earning money or striving for more money after they reach $50,000.
The reason is that humans hold fast to a number of wrong ideas about what will make them happy. Ironically, these misconceptions may be evolutionary necessities. Imagine a species that figured out that children dont make you happy, says Gilbert. We have a word for that species: extinct. There is a conspiracy between genes and culture to keep us in the dark about the real sources of happiness. If a society realized that money would not make people happy, its economy would grind to a halt.
When we try to project ourselves into the future, we make a systematic series of errors, and much of Stumbling on Happiness analyzes them. One common miscalculation is presentism, the belief that we will feel in the future the way we feel today. In a grocery store, feeling hungry, I try to shop for what I will want to eat next Wednesday, Gilbert says. Then Wednesday comes, and I ask myself, Why did I buy jalapeño pockets?
Secondly, humans are marvelous rationalizers. Find a large number of people whove been left standing at the altar and ask them if that was the worst day, or the best day, of their lives, Gilbert says. On the day it happens, almost without exception, they will say it is the worst day. But ask these same people the same question a year later and most will say it was the best day of their lives. People are much more resilient than they realize. In the lab, its very easy to get people to rationalize, but almost impossible to get them to foresee it. Rationalization is an invisible shield that protects us from psychological pain, but we dont realize that we are carrying it.
Much recent data show that people fare reasonably well in a variety of tragic and traumatic circumstancesChristopher Reeve was not unusual, Gilbert continues. Paraplegics are generally quite happy people. And blind people often say that the worst problem they have is that everyone assumes that they are sad: You cant read. But I can read. You cant get around. But I can get around. People do feel devastated if they go blind, but it does not last. The human mind is constituted to make the best of the situations in which it finds itself. But people dont know they have this ability, and thats the thing that bedevils their predictions about the future.
One of Gilberts colleagues, professor of psychology Ellen Langer, prefers to spend her time in the present, and she aims to analyze and share that experience with others though her many bookslike On Becoming an Artist: Reinventing Yourself through Mindful Creativityall of which explore her central theme of mindfulness. To Langer, mindfulness means noticing new things and drawing new distinctions. It doesnt matter whether what you notice is smart or silly, she says, because the process of actively drawing new distinctions produces that feeling of engagement we all seek. Its much more available than you realize: all you need to do is actually notice new things. More than 30 years of research has shown that mindfulness is figuratively and literally enlivening. Its the way you feel when youre feeling passionate.

Everyone says they want to live in the present, but theres a paradox: If youre not in the present, youre not there to know youre not there, says Langer, with a smile. So how do you get there? This work tells us how: when youre actively noticing new things, you become more aware of context and perspective. You end up with a healthier respect for uncertainty, something we are taught to fear. Our baseline state should be mindful; its how we should feel virtually all the time.
What stops us, according to Langer, are our fears of evaluation, our acceptance of absolutes, and our mindless ideas about mistakes. All three are actually different facets of the same sensibility. Anything hierarchical suggests that there is a single metrica right way of understanding the world, and better and worse ways to view things, she explains. But the world is a social construct. Mistakes are not mistakes in all contexts. With writing and art, mistakes tend to make the product more interesting. The major difference between a machine-made rug and a handmade one is that the regularity of the machine-made rug makes it uninteresting. Errors give the viewer something to hold onto. When you make a mistake in a painting, ifinstead of trying to correct the mistakeyou incorporate it into what you are doing and go forward, you are working mindfully. And when we ask viewers to choose between this kind of art and flawless works, people say they prefer the mindfully created pieces.
We also have mistaken notions of talent, Langer continues. People learn about activities as if there are absolute standards. Think about a jockey, a boxer, and an archer: three very different sports. Which one has athletic talent? Or suppose someone tells you that you have no artistic talentyou cant be a Pollock, Mondrian, Klee, or Picasso. But they are so different from each other! Act mindfully, and that state of consciousness leaves its footprint in what we do. Mindfulness is the essence of charisma; when people are there, we notice. When you dont take the world as given, but as full of possibilities, it becomes endlessly exciting.
The positive psychology class Ben-Shahar teaches at Harvard aims to keep its students engaged and excited, too. As they filter in, sit down, and boot up their laptops, a Whitney Houston song plays through the sound system in Sanders Theatre. Ben-Shahar, in black slacks and a blue pullover sweater, fiddles with his own laptop and brings up the first image on the screen for todays lecture on self-esteem: its a New Yorker cartoon of a troubled man writing in his diary, Dear Diary, Sorry to bother you again... During the lecture, Ben-Shahar will flesh out his discussion with images and film clips, along with concepts and research citations. He also shares a personal experience with the class, telling how, in his 20s, as a College graduate who had been a national squash champion, he nonetheless realized that I didnt have the answers. External validation broke down. I had the success and validation, but still experienced low self-esteem.
This is another way that positive psychology classes are different: they are experiential. There are two levels to the course, Ben-Shahar says. One is, like any other course, an introduction to the research and to the field. But secondly, students explore ways to apply these ideas to their lives and communities. They write response papers and perform exercises, connecting these theories with their own lives and experiences. We try to ask, to use William Jamess phrase, What is the cash value of these ideas?
It is clear that the cash value of positive psychology can be far greater than enhanced well-being, though that is a good start. Vaillant brings up one of positive psychologys constructs, forgiveness, in contrasting the Treaty of Versailles and the Marshall Plan. After World War I, Germany agreed not only to apologize but to send its countrymen to rebuild France. The French rejected this on the grounds that it would hurt employment in France if the Germans rebuilt it, and insisted instead on monetary reparations. In contrast, Vaillant says, The Marshall Plan put people in Gary and Pittsburgh out of work by giving the Germans and Japanese more efficient steel mills. But the result of Versailles was World War II and the Holocaust. The Marshall Plan led to 60 years of peace in Western Europe for the first time in recorded history.
Forgiveness, of course, means trusting someone who has hurt you, and so inevitably runs a risk. But positive psychology says such risks are worth taking. You hope to free up people in their lives, says Langer, so they will take more chances and live more before they die.
