The Happiness Equation: Science has Found the Missing Link

"If you could say in one word what you want more of in life, what would that be?" That question has been asked time and time again in countless polls and surveys. Overwhelmingly, the number 1 answer is...

...greater happiness.

Most people want to be happier- in our personal lives, our relationships and our work. Parents want it for their children. And most parents are not happy unless their kids are. If you have children, how many times have you said or thought this?

“I just want you to be happy.”

But what is happiness, really?

What Happiness Actually Means

The word happy comes from the Middle English hap, meaning “good luck.” Early versions of the word were more about luck than joy — as if happiness were something that happened to you, not something you could create.

Today, dictionaries define happiness as:

• Oxford English Dictionary: “Feeling or showing pleasure or contentment.”

• Merriam-Webster: “A state of well-being, a pleasurable or satisfying experience.”

  
  

But research in neuroscience and positive psychology suggests happiness is more than a fleeting feeling — it’s a trainable state of mind.

The Surprising Science Behind Happiness

In a landmark 2007 study of over 10,000 people in 48 countries, happiness ranked as more important than success, intelligence, relationships, and even meaning in life (Perspectives on Psychological Science).

And yet, according to Harvard psychologist Daniel Gilbert, author of Stumbling on Happiness, we’re not nearly as good at finding joy as we think we are. His research shows that the things we plan for happiness — promotions, purchases, perfect vacations — often fall flat. What actually sparks happiness? The things we stumble upon.

Gilbert found a direct connection between curiosity and happiness:

“People want to be happy, and all the other things they want are typically meant to be a means to that end.” Daniel Gilbert, PhD

Curiosity: The Hidden Key to Joy

A global Gallup survey of more than 130,000 people found two experiences most strongly linked to daily happiness:

1. Having someone to count on for help

2. Learning something new yesterday

   
   

In other words, distilled down into simplest terms, happiness is connection and curiosity.

Two pioneers of positive psychology, Dr. Martin Seligman and Dr. Chris Peterson, identified curiosity as one of the top five human strengths most correlated with happiness and life satisfaction. And psychologist Todd Kashdan, author of Curious? Discover the Missing Ingredient to a Fulfilling Life, explains why:

“Curiosity — a genuine desire to know more — opens us to new experiences and keeps life rich and meaningful.”

Why Curiosity Changes Everything

When your curiosity is activated, your brain shifts gears. Research shows that curiosity:

• Enhances learning and memory retention

• Reduces anxiety and depression

• Boosts creative problem-solving

• Strengthens relationships through empathy and open-mindedness

• Improves decision-making by reducing bias and assumptions

  
  

In short, curiosity makes you smarter, healthier, and happier. It reframes obstacles as opportunities, fuels innovation, and helps us enter the psychological “flow” state that leads to creativity and peak performance.

The Bottom Line

Curious people succeed — not by chasing happiness, but by creating it. It’s the secret ingredient shared by leaders, artists, entrepreneurs, and lifelong learners.

When we make curiosity our superpower, everything else — fulfillment, growth, and genuine happiness — follows naturally.

That’s the kind of success that feels like joy you earned. That’s the science of happiness at work.
