The 3 Major Sources of Happiness

Happiness has traditionally been considered an elusive and evanescent thing. To some, even trying to achieve it is an exercise in futility. It has been said that “happiness is as a butterfly which, when pursued, is always beyond our grasp, but which if you will sit down quietly, may alight upon you.”

Social scientists have caught the butterfly. After 40 years of research, they attribute happiness to three major sources: genes, events and values. Armed with this knowledge and a few simple rules, we can improve our lives and the lives of those around us.

But even demographically identical people vary in their happiness. What explains this? The first answer involves our genes. Researchers at the University of Minnesota have tracked identical twins who were separated as infants and raised by separate families. As genetic carbon copies brought up in different environments, these twins are a social scientist’s dream, helping us disentangle nature from nurture. These researchers found that we inherit a surprising proportion of our happiness at any given moment — around 48 percent. (Since I discovered this, I’ve been blaming my parents for my bad moods.)

If about half of our happiness is hard-wired in our genes, what about the other half? It’s tempting to assume that one-time events — like getting a dream job or an Ivy League acceptance letter — will permanently bring the happiness we seek. And studies suggest that isolated events do control a big fraction of our happiness — up to 40 percent at any given time.

But while one-off events do govern a fair amount of our happiness, each event’s impact proves remarkably short-lived. People assume that major changes like moving to a warmer climate or getting a big raise will make them permanently better off. They won’t. Huge goals may take years of hard work to meet, and the striving itself may be worthwhile, but the happiness they create dissipates after just a few months. So don’t bet your well-being on big one-off events. The big brass ring is not the secret to lasting happiness.

To review: About half of happiness is genetically determined. Up to an additional 40 percent comes from the things that have occurred in our recent past — but that won’t last very long.

That leaves just about 12 percent. That might not sound like much, but the good news is that we can bring that 12 percent under our control. It turns out that choosing to pursue four basic values of faith, family, community and work is the surest path to happiness, given that a certain percentage is genetic and not under our control in any way.

The first three are fairly uncontroversial. Empirical evidence that faith, family and friendships increase happiness and meaning is hardly shocking. Few dying patients regret overinvesting in rich family lives, community ties and spiritual journeys.

Along the way, I learned that rewarding work is unbelievably important, and this is emphatically not about money. That’s what research suggests as well. Economists find that money makes truly poor people happier insofar as it relieves pressure from everyday life — getting enough to eat, having a place to live, taking your kid to the doctor. But scholars like the Nobel Prize winner Daniel Kahneman have found that once people reach a little beyond the average middle-class income level, even big financial gains don’t yield much, if any, increases in happiness.

So relieving poverty brings big happiness, but big income, per se, does not. Even after accounting for government transfers that support personal finances, unemployment proves catastrophic for happiness. Abstracted from money, joblessness seems to increase the rates of divorce and suicide, and the severity of disease.

And according to the General Social Survey, nearly three-quarters of Americans wouldn’t quit their jobs even if a financial windfall enabled them to live in luxury for the rest of their lives. Those with the least education, the lowest incomes and the least prestigious jobs were actually most likely to say they would keep working, while elites were more likely to say they would take the money and run. We would do well to remember this before scoffing at “dead-end jobs.”

Assemble these clues and your brain will conclude what your heart already knew: Work can bring happiness by marrying our passions to our skills, empowering us to create value in our lives and in the lives of others. Franklin D. Roosevelt had it right: “Happiness lies not in the mere possession of money; it lies in the joy of achievement, in the thrill of creative effort.”In other words, the secret to happiness through work is earned success.

If you can discern your own project and discover the true currency you value, you’ll be earning your success. You will have found the secret to happiness through your work.
