Happiness as an Evolved Signal
Before we can design for happiness, we need to understand what happiness actually is. Our working theory — grounded in evolutionary biology, neuroscience, and years of personal experimentation — is that happiness is fundamentally an evolved chemical sensation. It is your body's way of telling you that your needs in terms of survival are being met.
This is a radical reframe. It means that happiness is not something you achieve through external success or material accumulation. It is something that emerges naturally when the basic conditions of human flourishing are in place.
The Evolutionary Basics
What are these basic conditions? They are the things that kept our ancestors alive and thriving for hundreds of thousands of years:
Air. Clean, fresh air. Our bodies evolved in environments with air quality vastly different from what most of us breathe today.
Water. Pure, abundant water. Hydration affects every system in your body, including your mood and cognitive function.
Sleep. Deep, restorative sleep aligned with natural light cycles. Sleep is perhaps the single most undervalued contributor to happiness in modern life.
Food. Whole, nutrient-dense food that your body was designed to process. Not the engineered products that dominate modern diets.
Movement. Regular, varied physical activity. Our bodies evolved to move constantly — walking, climbing, carrying, building. Sedentary life is a profound mismatch with our biology.
Connection. Deep, meaningful relationships with other humans. We are fundamentally social creatures, and isolation is one of the greatest threats to our happiness.
Nature. Regular contact with the natural world. Green spaces, sunlight, natural sounds, open sky.
The Mismatch Problem
Modern life has created an enormous gap between the conditions our bodies evolved for and the conditions we actually live in. We breathe polluted air, drink treated water, sleep under artificial light, eat processed food, sit for hours, maintain shallow social connections, and spend most of our time indoors.
This mismatch is, we believe, at the root of much of the unhappiness in the modern world. Not all of it — genetics and context play important roles — but a significant portion.
Designing from the Basics
When we work with individuals, organizations, and cities, we always start here. Before we address complex psychological frameworks or sophisticated interventions, we ask: are the evolutionary basics in place? Is this person sleeping well? Moving enough? Eating real food? Spending time with people they care about?
More often than not, the greatest gains in happiness come from getting these fundamentals right. It is not glamorous work. But it is the foundation upon which everything else is built.
