The Science and Research on Gratitude and Happiness

Happiness and gratitudeWhat is happiness? What is gratitude?

We each have our own definitions of these, and for the most part, they will probably sound pretty similar.

But if we were to take a deeper dive into the two, we would we find out more about ourselves, for instance, our behavioral tendencies and emotional wellbeing, than just what is a standard definition of each.

The English language has about 550 to 600 words for different emotional experiences, two of these “emotional experiences” are gratitude and happiness (Averill, 1997).

Gratitude and happiness are two topics that have been long researched but only recently became hot topics. As more and more people are becoming aware of the benefits of applying Positive Psychology evidence-based theory, science, and methods to their daily life, gratitude and happiness are rising to the top of the ‘priority self’-checklist.

If we take a deeper look at gratitude, we find that ‘gratia’, is the Latin origin for ‘gratitude’ and means grace, graciousness, or gratefulness. Gratitude is an appreciation from receipt of something tangible or intangible from an individual (Giving thanks makes you happier).

As stated before, happiness has many definitions, but let’s look at the one from Positive Psychology, it’s defined as experiencing frequent positive emotions, like joy, pride, and interest with less negative emotions like anger, sadness, and anxiety (Lyubomirsky, 2008). Furthermore, happiness is related to life satisfaction, moments of pleasure, and appreciation of life (Khoda, 2016).

Gratitude and happiness are more than just a state of mind or a gesture. There are some serious science-based theories behind each of these emotional states of being.

The Psychology of Gratitude and Happiness

Researchers in Positive Psychology have found that gratitude and happiness are always strongly correlated. A possible theory is that gratitude moves people to experience more positive emotions, to thoroughly enjoy the good experiences, better their health, face adversity, and develop and maintain relationships of strength, which in turn makes you happier.

Three common ways people can express their gratitude are:

  1. By being gracious of their past (i.e., think of positive childhood memories)
  2. By being gracious for the present (i.e., taking time to be present and enjoy)
  3. By being grateful for what’s to come (i.e., hopeful and optimistic of the future) (Giving thanks makes you happier).

Gilbert Keith Chesterton, (often known as G.K. Chesterton) is a prolific English writer, poet, philosopher, etc. who coined the quote “I would maintain that thanks are the highest form of thought, and that gratitude is happiness doubled by wonder” (Sacasas, 2010).

Chesterton takes the attitude that giving thanks or showing gratitude for whatever you are doing is critical in order to be happy. In addition, appreciate anything and everything you have, or don’t have anything at all. In short – take nothing for granted (Taylor, 2014).

A Look at Science and Research

Does the happier you are, correlate to the longer you live? Yoichi Chida and Andrew Steptoe (2008) attempted to answer this question.

Chida and Steptoe (2008) conducted a meta-analysis on 35 longitudinal studies; the researchers found that happiness positively effects longevity. These positive effects included: a more positive psychological wellbeing and a lower mortality rate for everyone whether they were healthy or sick (Carr, 2011).

Healthy population studies have found that when participants exhibited a positive affect, like joy, happiness, energy and vigor, life satisfaction, optimism, and a sense of humor – there was a lower mortality rate (Carr, 2011).

Adding to the evidence that happiness correlates with a longer life are researchers Danner, D.D., Snowdon, D.A., & Friesen, W.V. (2001). They completed a large follow-back study with 180 nuns in the US. All of the nuns had a similar lifestyle, diet, and schedule.

Danner et al. (2001) instructed the nun participants to write essays as they entered into their religious order. The nuns wrote about themselves and their life from childhood to present day, and their hopes and dreams for their lives.

The nuns were unaware that their essays would be analyzed for a happiness and longevity study. The researchers found that, about 50 some years later, 90% of the happiest nuns lived past 85 (years old), and only 34% who scored as the least happy lived past 85 (Carr, 2011).

We can see that happiness can increase our longevity. However what are the factors that determine happiness? Sonya Lyumbomirsky (2007), a psychology researcher, theorized that there are three causes of happiness.

  1. Genetic happiness set-point: is responsible for 50% of our happiness, determined by our personalities.
  2. Intentional activity: accounts for about 40% of our happiness, meaning the activities that we intentionally set out to do throughout our lives, that can better our wellbeing or increase our happiness.
  3. Environmental circumstances: account for 10% of the reason we are happy, usually it depends on the circumstances that which we are surrounded with and how this encourages or inhibits skills and opportunities for us to achieve happiness (Lyumbomirsky, 2007).

While there are different causes of happiness, one way for sure to bring about more happiness is gratitude.

Leaders in Positive Psychology, researchers Dr. Robert A. Emmons and Dr. Michael E. McCullough, studied gratitude and directed participants to write a few sentences weekly on certain topics.

The topics ranged from what they were grateful for to what irritants they had encountered that week. At 10 weeks, the researchers found that the participants who wrote about gratitude were more hopeful about the future and had less medical appointments, and exercised more (Giving thanks can make you happier).

Other Interesting Research and Studies

There are many researchers looking at how to measure and predict positive emotions in order to share with the world the key factors responsible or what are the best tools and skills to practice to be happier.

Gratitude Predicts Hope and Happiness: A Two-Study Assessment of Traits and States (vanOyen Witvliet, 2018).

vanOyen Witvilet and her team of researchers studied and assessed how gratitude could possibly predict hope and happiness, respectively. The researchers assessed gratitude writing in the intervention group.

Their theory of gratitude was inspired by, Roberts (2004), in that they found that “gratitude is about givers, gifts, recipients, and the attitudes of giver and recipients toward one another.” Gratitude compared to joy and hope is a much deeper social emotion, whereas joy is a result of a behavior or action, and hope is a thought of a future action or good (p. 65).

Counting Blessings Versus Burdens: An Experimental Investigation of Gratitude and Subjective Well-Being in Daily Life, by Robert A. Emmons and Michael E. McCullough.

Researchers Emmons and McCullough assessed the effect of having a grateful outlook on a person’s psychological and physical wellbeing. A total of 3 studies were conducted, studies 1 and 2, participants were randomized into 1 of 3 groups:

1. Hassles,

2. Gratitude listing,

3. Either neutral life events or social comparison.

For the first two studies, the participants were also asked to keep a record of their moods, coping behaviors, health behaviors, physical symptoms, and overall life appraisals.

For the third study, prior to enrollment, these participants had been diagnosed with a neuromuscular disease, and were randomly assigned to either the gratitude intervention or the control group.

Although the researchers were looking to see benefits in both the positive affect and somatic realm, only in the social-emotional aspect did the participants show a higher positive affect (Emmons and McCullough, 2003).

Savoring Walks.

A study conducted at Loyola University Chicago, by Fred Bryant and Joseph Veroff (2007); found that a “savoring walk” each day can help with happiness.

How exactly? The participants took a “savoring walk” daily for a week, and reported back that there was an increase in their overall happiness. Their explanation surmises that if you take the time to notice the good things in life you will feel happier.

Deeper conversations provide for a happier life.

Psychological researchers Matthias R. Mehl, Shannon E. Holleran, C. Shelby Clark, and Simine Vazire looked at the difference in happiness for people who were less social and had more superficial conversations versus people that were more social and had deeper conversations.

Their findings showed that those that had more deep conversations and socialized more frequently with others were happier (Association of Psychological Science, 2010).

Is There a Link Between Happiness and Gratitude?

Happiness linked to gratitiude

There is a direct link between happiness and gratitude. Expressing gratitude brings about happiness for the one giving thanks. The more someone is thankful or feels gratitude, the less there is time or room for negative thoughts.

Lyubomirsky (2008) provides 8 ways to boost gratitude in her book, “The How of Happiness: A New Approach to Getting the Life you want,” and a brief online version “Eight Ways Gratitude Boosts Happiness.”

First, she directs the reader that being grateful offers us a moment to savor the joy we are currently experiencing, which in turn lessens the dreariness of any negative going on at the time.

Then her second point, which is pretty interesting and rings true so effectively, is that the more you practice and express gratitude the more self-worth and self-esteem you feel, whether it’s thinking about what others do for you, or what you have done (for yourself or others) it adds to your confidence and how effective you are at this thing called life.

For people that have experienced some of the most traumatizing experiences or situations, they have found positive effects from those experiences or from life itself to be thankful for.

These positive effects include adjusting, processing, and moving on from the trauma. Gratitude can also help with building empathy for others, and social bonds whether pre-existing or new.

Gratitude helps us to be less negative overall.

How Does Gratitude Bring Happiness?

Gratitude is a wonderful practice to learn and practice over and over every day.

Gratitude is the most giving state of mind that we can train our thinking to stay in. When we give or receive gratitude we are happier for it.

Gratitude involves and evolved from one of the basic animal interactions, acknowledgment. Obviously, acknowledgment can be much more established and overt than a basic understanding of “I see you” “I feel you” or “I hear you.”

But with gratitude it is taking acknowledgment 20 steps forward, in saying, “not only do I see/hear/feel you I thank you for X.”

Whatever the X is — doesn’t really matter… It’s really about that acknowledgment and the .5 seconds to 30 minutes it takes to feel grateful to someone or to something non-living – that brings us back from all of our negative thoughts, grievances, and frustrations, etc.

Tennen and Afflek (2002) found that when people are faced with adversity or traumas if they are able to experience gratitude, they are able to push through the adversity or trauma and be more resilient.

Furthermore, researchers Witvliet, Knoll, Hinman, & DeYoung (2010) found that after an interpersonal offense, if a victim can concentrate or bring to attention the lesson(s) learned, how they were resilient, or how they grew, it provides greater joy, positivity, and overall better cardiovascular health for that temporary moment.

When people are focused on the good and prioritize any of the benefits, they are practicing benefit-focused reappraisal, most similar to the phrase of “finding the silver-lining” (Baker, Williams, Witvliet, & Hill, 2016).

Does Gratitude Multiply Happiness?

Yes. Absolutely it does.

Feeling gratitude or receiving gratitude makes both parties happier or see things from a more positive perspective. How could it not, right? You are literally thanking someone or something for something that is positive.

Positivity rubs off, and when you feel more positive you feel happier. With positive situations and positive thoughts, it’s hard to think of negative situations or negative thoughts. But why is that?

Answer: because they are still there even when we feel overly grateful for all of the good.

However, we are able to accept the negative thoughts or situations that we have or are in. When we accept whatever our circumstances are, we waste much less energy on negative emotions such as rejecting or denying the negative. Instead, we are able to accept everything about our circumstance – taking in both the good and the bad.
