Understanding the science of happiness

With the rise of positive psychology, there has been an ever-increasing focus on the good things in life: compassion, forgiveness, joy, elevation, success, thriving, and well-being – and, of course, happiness.

What used to be the realm of entertainment magazines and self-help gurus is now an established and expanding corner of the scientific literature. Now, instead of focusing only on depression, anxiety, and other more negative aspects of life (all completely worthy of attention and research, of course), scholars are asking big questions about the positive things in life.

Read on to learn more about those questions and get a glimpse at findings from the research aimed at answering them, along with some excellent resources for further information.


A Look at the Science of Happiness

So what is the “science of happiness?

This is one of those times when something is exactly what it sounds like – it’s all about the science behinds what happiness is and how to experience it, what happy people do differently, and what we can do to feel happier.

This focus on happiness is new to the field of psychology; for many decades – basically since the foundation of psychology as a science in the mid- to late-1800s – the focus was on the less pleasant in life. The field focused on pathology, on the worst-scenario cases, on what can go wrong in our lives.

Although there was some attention paid to well-being, success, and high functioning, the vast majority of funding and research was dedicated to those who were struggling the most: those with severe mental illness, mental disorders, or those who have survived trauma and tragedy.

While there’s certainly nothing wrong with doing what we can to raise up those who are struggling, there was an unfortunate lack of knowledge about what we can do to bring us all up to a higher level of functioning and happiness.

Positive psychology changed all of that. Suddenly, there was space at the table for a focus on the positive in life, for “what thoughts, actions, and behaviors make us more productive at work, happier in our relationships, and more fulfilled at the end of the day” (Happify Daily, n.d.).

The science of happiness has opened our eyes to a plethora of new findings about the sunny side of life.

Current Research and Studies

For instance, we have learned a lot about what happiness is and what drives us.

Recent studies have shown us that:

  • Money can only buy happiness up to about $75,000 – after that, it has no significant effect on our emotional well-being (Kahneman & Deaton, 2010).
  • Most of our happiness is not determined by our genetics, but by our experiences and our day-to-day lives (Lyubomirsky, Sheldon, & Schkade, 2005).
  • Trying too hard to find happiness often has the opposite effect and can lead us to be overly selfish (Mauss et al., 2012).
  • Pursuing happiness through social means (e.g., spending more time with family and friends) is more likely to be effective than other methods (Rohrer, Richter, Brümmer, Wagner, & Schmukle, 2018).
  • The pursuit of happiness is one place where we should consider ditching the SMART goals; it may be more effective to pursue “vague” happiness goals than more specific ones (Rodas, Ahluwalia, & Olson, 2018).
  • Happiness makes us better citizens – it is a good predictor of civic engagement in the transition to adulthood (Fang, Galambos, Johnson, & Krahn, 2018).
  • Happiness leads to career success, and it doesn’t have to be “natural” happiness – researchers found that “experimentally enhancing” positive emotions also contributed to improved outcomes at work (Walsh, Boehm, & Lyubomirsky, 2018).
  • There is a linear relationship between religious involvement and happiness. Higher worship service attendance is correlated with more commitment to faith, and commitment to faith is related to greater compassion. Those more compassionate individuals are more likely to provide emotional support to others, and those who provide emotional support to others are more likely to be happy (Krause, Ironson, & Hill, 2018). It’s a long road, but a direct one!


The Science Behind Gratitude and Happiness

The science is clear on gratitude and happiness: they are intricately linked.

Studies show that it’s likely a two-way street, in that those who practice gratitude on a regular basis are more likely to report high levels of happiness, and those who are happy are more likely to feel high levels of gratitude.

One of the most well-known studies on gratitude and happiness is that conducted by Dr. Robert A. Emmons and Dr. Michael E. McCullough in the early days of positive psychology. They divided participants into three groups:

  • The first was instructed to write a few sentences a week about all the things they were grateful for that had occurred in that week.
  • The second was instructed to write a few sentences a week about the things that bothered or stressed them out during that week.
  • The third was instructed to write a few sentences about events that had an impact on them over the past week (with no mention of “good” or “bad” events).


The study lasted for ten weeks, and at the end, the researchers measured the optimism and well-being of their study participants. Those who wrote about things they were grateful for were more optimistic, enjoyed higher well-being, and even exercised more and had fewer trips to the doctor than those who wrote about their daily annoyances and irritations (Emmons & McCullough, 2003).

These findings affirmed what many of us already intuited: that actively looking for the good things that happen to us makes us happier people. This concept has been embraced and incorporated into many positive psychology interventions for good reason – because it really works!


The Scientific Research on Happiness at Work

There’s been a ton of research on the effects of happiness in the workplace. Much of this is driven by companies who want to find a way to improve productivity, attract new talent, and get a dose of good publicity, all at the same time. After all, who wouldn’t want to do business with and/or work for a company full of happy employees?

Although the jury is still out on exactly how happy employees “should” be for maximum productivity, efficiency, and health, we have learned a few things about the effects of a happy workforce:

  • People who are happy with their jobs are less likely to leave their jobs, less likely to be absent, and less likely to engage in counterproductive behaviors at work.
  • People who are happy with their jobs are more likely to engage in behavior that contributes to a happy and productive organization, more likely to be physically healthy, and more likely to be mentally healthy.
  • Happiness and job performance are related—and the relationship likely works in both directions (e.g., happy people do a better job and people who do a good job are more likely to be happy).
  • Unit- or team-level happiness is also linked to positive outcomes, including higher customer satisfaction, profit, productivity, employee turnover, and a safer work environment.
  • In general, a happier organization is a more productive and successful organization (Fisher, 2010).


To sum up the findings we have so far, it’s easy to see that happiness at work does matter – for individuals, for teams, and for organizations overall. We don’t have all the answers about exactly how the relationship between happiness and productivity works, but we know that there is a relationship there.

Lately, many human resources managers, executives, and other organizational leaders have decided that knowing there’s a relationship is good enough evidence to establish happiness-boosting practices at work, which means that we have a lot of opportunities to see the impact of greater happiness at work in the future!

Research in this field is booming, and new findings are coming out all the time. Here are a few of the most interesting facts and findings so far:

  1. Happiness is linked to lower heart rate and blood pressure, as well as healthier heart rate variability.
  2. Happiness can also act as a barrier between you and germs – happier people are less likely to get sick.
  3. People who are happier enjoy greater protection against stress and release less of the stress hormone cortisol.
  4. Happy people tend to experience fewer aches and pains, including dizziness, muscle strain, and heartburn.
  5. Happiness acts as a protective factor against disease and disability (in general, of course).
  6. Those who are happiest tend to live significantly longer than those who are not.
  7. Happiness boosts our immune system, which can help us fight and fend off the common cold.
  8. Happy people tend to make others happier as well, and vice versa – those who do good, feel good!
  9. A portion of our happiness is determined by our genetics (but there’s still plenty of room for attitude adjustments and happiness-boosting exercises!).
  10. Smelling floral scents like roses can make us happier.
  11. Those who are paid by the hour may be happier than those on salary (however, these findings are limited, so take them with a grain of salt!).
  12. Relationships are much more conducive to a happy life than money.

Here is the source for the first six facts and findings, as well as for the latter 11.


What are the 36 Questions?

The 36 questions were developed by researchers Aron, Melinat, Aron, Vallone, & Bator in 1997. These three sets of questions offer a surprisingly effective way to get to know someone and improve your connection. As we know from findings in the science of happiness, human connection is one of the most vital ingredients in a happy and healthy life.

Some even say these 36 questions can encourage love to blossom! If you want to give it a shot and boost the quality of your connection with someone, print these questions out and walk through them together. It should take about 45 minutes to get through all of them.

The Surprising Science of Happiness TED Talk by Dan Gilbert

This TED Talk introduced many people to the science of happiness and helped popularize some of the most pervasive and widely shared ideas about happiness. These ideas include:

  • Lottery winners and paraplegics generally report similar levels of happiness one year after winning the lotto/losing their legs.
  • This is because humans are excellent at adapting to changes in their situation; most events don’t change your long-term happiness much!
  • We all have the ability to create “synthetic happiness,” a form of happiness we make when we are forced to because we didn’t get what we wanted.
  • A good portion of our happiness is dependent on our thoughts rather than what happens to us.
