Science of Happiness
Introduction to the Science of Happiness
Over the last twenty years we have seen a dramatic upsurge in scientific studies aimed at discovering the causes of “subjective well being” or to put it simply, discovering what makes happy people happy. Happiness, like any psychological state, is not an easy thing to measure, and so the results of these studies are not perfectly reliable. Yet we are slowly getting a clearer picture of what we can do to find greater happiness and fulfillment. Many of the scientific studies point to certain key areas that can strongly impact our pursuit of happiness. Let’s take a look at the areas of consensus that are emerging through the new science of happiness.
Each “area of consensus” has three sections:
1) A “top line.” This is the take-home message; a brief paragraph describing how we can apply the results of the scientific studies to our own lives.
2) A more detailed review on areas of agreement, as well as remarks on valuable or intriguing insights of particular studies.
3) A bibliography of key studies, as well as related studies.
Note: These pages will be frequently updated as we incorporate more studies on the science of happiness.
1. Communicating
The top line: People who have one or more close friendships appear to be happier. It doesn’t seem to matter if we have a large network of close relationships or not. What seems to make a difference is if and how often we cooperate in activities and share our personal feelings with a friend or relative. Simply put, it’s not the quantity of our relationships, but the quality that matters.
In one study people were asked on random occasions about their mood. They were found to be happiest with their friends, followed by family members, and least happy if they were alone (Larson).
Another study constructed a scale of cooperativeness, ie how willing people were to constructively engage in activities with others. This study showed that the cooperativeness of an individual was a predictor of their happiness, though it did not conclusively show if their cooperation resulted in happiness or the other way around (Lu).
A study on the quality of relationships found that to avoid loneliness people needed only one close relationship coupled with a network of other relationships. To form a close relationship required a growing amount of “self-disclosure,” or a willingness to reveal ones personal issues and feelings, and without it people with friends would still be lonely (Weiss). A similar study found that some students who had many friends with whom they often spent time were still plagued by loneliness, and this seemed to be related to their tendency to talk about impersonal topics such as sports and pop music instead of their personal life (Weeler).

2. Caring
The top line: People who volunteer or simply take a little extra time to assist and care for others around them seem to be happier. “Caring” can be as simple as reaching out to a workmate or classmate who looks lonely or is struggling with an issue. Or it can be something more organized, such as volunteering to care for the homeless or disabled. Studies show that people who reach out like this feel better about themselves, and experience a stronger sense of “belonging,” usefulness and purpose.
Volunteering seems to have the most significant impact. One large-scale study compared the psychology of elderly volunteers with non-volunteers and found that retirees older than 65 who volunteered rated significantly higher on life satisfaction and will to live, and had fewer symptoms of depression (Hunter). In the same study a group of young volunteers did not experience more benefit than non-volunteers. The authors of the study raise the possibility that the younger group might not have experienced the same sort of satisfaction because they were not as self-motivated as the older group. In oter words many of these students may have been encouraged to volunteer by their schools or did so to boost their chances of getting into college.
A well-known study on the topic “It’s good to be good” argues that a strong link exists between the well-being and happiness of people on the one hand, and the compassion they express in their attitudes and actions, as long as they do not have too many caring responsibilities to handle (Post).

3. Exercising
The top line: Regular exercise has a significant effect on our mood, especially in relieving depression. For many people with mild to moderate depression, working out at least three times a week, especially for more than a few months, appears to lift them out of the blues. The longer they continue to do this, the greater the impact.
Have you ever noticed that you feel great after going for a run? Do you love working out or playing sports on a regular basis? It turns out that you are not alone, and that exercise has a big effect on mood and mental well-being.
While it might be no surprise that exercise can improve your mood, a good deal of scientific research has been done to discover the possible reasons for this. Some researchers argue that exercise may act as a diversion from negative thoughts, and the mastery of a new skill may be important. Some studies indicate that social contact between people who are working out or involved in sports may be an important source of satisfaction as well. Still others think that physical activity causes the brain to release chemicals called endorphins that cause one to feel good after exercising.
Most of the researchers looking at exercise and mood compared groups of people who were exercising to those who were not. They then looked to see if those who were exercising felt better in the short term. Some researchers compared exercising to treatments for depression such as antidepressant medications or cognitive-behavioral therapy.

4. Getting in the Flow
Do you ever find yourself so completely immersed in what you’re doing that you lose track of time? All of a sudden you look up at the clock and realize that hours have passed and you missed dinner time? Think a minute about this. When does this loss of time and total engagement typically occur for you? This could apply to a martial artist completely absorbed in perfecting a flying kick, or a violinist fiercely concentrating on a complex symphony. One may find still greater happiness working towards long-term, meaningful goals. This is perhaps one reason why religious people with a sense of “mission” seem comparatively happier. Viktor Frankl, who survived a Nazi concentration camp, once said “What man actually needs is not a tensionless state but rather the striving and struggling for some goal worthy of him.” A growing body of scientific evidence seems to support this.
Scientists such as Mihaly Csikszentmihalyi have studied the impact of Flow states on human happiness, productivity and success. In one study 250 high-flow and low-flow teenagers were asked to report on their feelings and activities at regular intervals. The high-flow teenagers on average reported more time spent on hobbies, sports and homework. The high-flow teenagers also measured higher levels of self-esteem and engagement. Interestingly, however, the high-flow teenagers self-reported lower levels of fun than the low-flow teenagers. Apparently, high-flow teenagers see their low-flow peers as experiencing more fun engaging in low-flow activities, such as video games, TV or socializing. However, the high-flow kids end up having greater long term happiness as well as success in school, social relationships and careers.
If Flow has such incredible benefits to our happiness, relationships and success, then why do we habitually choose low-flow activities? Why do we, in the moment, choose another episode of American Idol over a game of pickup basketball? One hypothesis is that the high-flow activities require more initial motivation because they do require skill and concentration. In other words, high-flow activities are work! But work that pays off. And unfortunately low-flow activities, such as watching TV, often contribute to low levels of depression.

5. Religious and Spiritual Engagement
Spirituality and prayer also provide people with an opportunity to engage in a meditative act. Meditation has been shown to have a strong link with well-being because it calms the body, reduces stress and anxiety, and also supports positive thinking.
Finally, both spirituality and organized religion can help provide people with perspective and hope. By believing in something greater than themselves, it may help them stay positive in times of sadness, and foster resilience.
Generally, religiosity can be defined as one’s relationship with a particular faith tradition or doctrine about a divine other or supernatural power, while spirituality can be defined as “the intrinsic human capacity for self-transcendence, in which the self is embedded in something greater than the self, including the sacred” and which motivates “the search for connectedness, meaning, purpose, and contribution.”1 But these abstract ideas are measured in many different ways, from frequency of church attendance to asking people “how religious are you?” As for mental well-being and happiness, studies look at both negative (i.e. depression) and positive indicators of mental well-being (i.e. self-reported happiness, self esteem, positive relationships with others).
Two recent surveys of the studies (meta-analyses) examine the different definitions and measurements of religiosity/spirituality as well as mental effects. One looks at adults, the other, adolescents, both with different results. A 2003 review of 34 studies with mainly adult populations found that personal devotion measures are most strongly related to mental well-being, while ideological measures showed less strong though positive effects, and institutional measures (i.e. religious service attendance) had the weakest. A 2006 review of 20 studies with adolescent populations (average age 10-20) reported that 90% of these studies show positive findings in the relationships between adolescent religious/spiritual engagement and mental well-being.3 In contrast to the mostly adult-based study, it was institutional involvement that had the largest effect on mental well-being, with ideological and personal devotion measures showing a smaller impact. Scientists suppose that the social and behavioral impact of institutional involvement may be more beneficial to young people, because it provides a sense of order and belonging during a difficult transitional period of their lives. In general, they found that religious and spiritual involvement was more beneficial to older teens’ mental well-being, perhaps because it reflects personal choices rather than imposed parental expectations. They also found that it has more of an impact for males, but are unsure why.
One important point about the studies is that, even though most researchers say they are looking at the “effect” of religion on mental well-being, the vast majority only show that religious and spiritual people report higher levels of happiness and mental well-being. This means that good mental well-being might predispose people to religious involvement or vice versa. To look at whether religiosity/spirituality causes better mental well-being, scientists must study people over a long period of time.

6. Cultivating Strengths and Virtues
The top line: The work of positive psychologists such as Seligman appears to show that the happiest people are those that have discovered their unique strengths (such as persistence and logic) and virtues (such as humanity and patience), and use those strengths and virtues for a purpose that is greater than their own personal goals. These kinds of people are doing what we have suggested in the section on “caring,” but on top of that they use their unique abilities and gifts to do it.
You may have strengths that are so natural to you that you may not even consider them strengths. Think about an episode in your life when you were at your very best. What qualities enabled you to perform like that?
While an infinite number of talents and strengths exist that humans can possess, Character Strengths and Virtues are ones that humanity morally values. When Martin Seligman and Chris Peterson sought to discover and classify common Character Strengths and Virtues across cultures, they created a classification of core virtues that humans morally value no matter what the cultural, racial and regional differences. Take the VIA Signature Strengths assessment to determine your top five Signature Strengths. (link here)
Current research indicates that you are most likely to value a job, relationship, hobby or institution that aligns with your core signature strengths and allows you to regularly utilize them. In fact, research indicates that using signature strengths in new and consistent ways, and building on your current strengths may more effectively improve wellbeing than trying to improve your weaknesses.

7. Positive Thinking: Optimism, Savoring, and Gratitude
Optimistic people view the same events as challenges and opportunities that pessimists may see as annoyances or frustrations. As a result, The only known downside to optimism is that optimists slightly underestimate risks, which is one of the reasons why professions were pessimism may prove to be more beneficial (such as law) also report higher levels of depression
Martin Seligman’s book Authentic Happiness has an optimism assessment you can take. If you score low, don’t despair! Optimism is not a fixed character trait! You can improve your optimistic outlook on life through your hard word and cognitive discipline. The book Authentic Happiness by Martin Seligman outlines exercises and strategies for improving your optimistic outlook on life.
