Is happiness something we’re born with, or does it come from what happens around us? A new study published in Nature Human Behaviour takes a deep dive into this question, looking at whether happiness comes more from who we are or from the world we live in.
Researchers aimed to understand what drives happiness in order to help shape better public policies that could boost well-being at a national and global level. Dr. Emorie Beck, lead author and Assistant Professor of Psychology at the University of California, Davis, explained: “We have to understand the sources of happiness to build effective interventions.”
The Big Question: Inside or Outside?
The core of the study asked whether happiness is shaped more by internal traits—such as personality—or external factors like health, relationships, and job satisfaction.
If external conditions are key, then governments and institutions should work to improve areas such as healthcare access, job opportunities, and housing. But if internal characteristics like optimism or resilience play a larger role, then programs focusing on mental wellness—such as therapy or mindfulness—would be more effective.
A Massive Data Set Across Five Countries
To explore the question, the research team analyzed data from over 40,000 people. These individuals had participated in long-term surveys over as many as 33 years. The participants were from five countries: Great Britain, Switzerland, Germany, the Netherlands, and Australia.
The surveys measured both overall life satisfaction and satisfaction in five specific areas:
-
Personal relationships
-
Work
-
Health
-
Income
-
Housing
Four Distinct Patterns of Happiness
The study found that people tend to fall into one of four roughly equal groups based on what influences their happiness:
-
Top-down – Happiness mostly comes from internal traits such as personality and mindset.
-
Bottom-up – Happiness is mostly shaped by external life circumstances.
-
Bidirectional – A mix of both internal and external factors influence happiness.
-
Unclear or Other – No clear pattern was found, possibly due to unmeasured influences.
Dr. Beck summed it up this way: “Some people are bottom-up; some are top-down. Some are influenced by both, and for others, the patterns are unclear.”
What the “Unclear” Group Could Mean
For people whose happiness didn’t clearly relate to internal or external factors, researchers believe there could be other external forces not included in the study—like community, political stability, or environmental conditions.
This finding hints at the complexity of measuring happiness. It suggests that current surveys might not fully capture the range of experiences that influence how happy someone feels.
Rethinking Public Policy on Happiness
One key takeaway from the study is that happiness is not the same for everyone. Policies based only on improving mental outlooks (top-down) or only external conditions (bottom-up) are likely to fall short.
Instead, public policies should address both areas, offering access to mental health care and self-development tools, while also improving healthcare, job security, housing, and social support. More importantly, strategies should be flexible, allowing individuals to choose the paths that work best for their own well-being.
Summary
This groundbreaking research reshapes how we understand happiness. It reveals that what makes people happy can vary significantly from person to person. Some find joy through personal mindset, others through life’s circumstances, and many from a mix of both.
For governments, this means a one-size-fits-all approach won’t work. Instead, happiness must be supported through broad yet adaptable programs that recognize our different needs, both within and beyond ourselves.
