It’s not a question of bank account. Nor of brilliant career or notoriety. After 85 years of observations, one of the most important studies ever carried out on human well-being reaches a conclusion that overturns many widespread beliefs: happiness arises from the quality of relationships, not from what we possess or show.
It is a discovery that also speaks to today’s Italy, where the race for performance, economic stability and “making it on your own” often leaves little room for authentic bonds.
The Harvard study
The Harvard Study of Adult Development begins in 1938, in a world profoundly different from ours. We are in the midst of the Great Depression and a group of researchers decides to follow 268 Harvard students over time to understand what would have made them healthy and satisfied adults. At the time it was thought that destiny was written above all in the genes or in the social class.
As the decades passed, the study grew and changed: 456 men from the working-class neighborhoods of Boston were also involved, offering a more realistic and less elitist look at American society. Today, the research includes over 1,300 descendants of the original participants, allowing us to observe how childhood experiences influence health, relationships and aging in subsequent generations.
Among the participants there is no shortage of well-known figures, such as John F. Kennedy, but the value of the study does not lie in illustrious biographies. It lies in the fact that, for more than eight decades, normal lives have been observed, with successful and failed marriages, periods of loneliness, work, illnesses, friendships that last and others that are lost.
Because relationships matter more than money and success
When the people involved were asked what they thought would make them happy, the answer was almost always the same: more money, more recognition, more success. However, the data collected over time tells another story.
People who live better and longer are those who can count on stable, sincere and supportive relationships. Family relationships, friendships, couple bonds and a sense of belonging to a community make the difference, much more than income or career.
Robert Waldinger, psychiatrist and current director of the practice, explains it without emphasis: satisfaction in relationships is one of the strongest indicators of physical and mental health. It’s not enough to “have someone close to you”, it’s important to feel listened to, to be able to count on someone else in difficult moments, to know that a reliable bond exists.
One fact is more striking than others: those who declared themselves satisfied with their relationships at 50 were healthier at 80, regardless of social class or level of education. A valid result both for former Harvard students and for those coming from economically fragile backgrounds.
Loneliness, health and “social training”
The study also highlights the other side of the coin: loneliness. Feeling alone, even among others, has effects comparable to well-known risk factors such as smoking or alcohol abuse. It increases the risk of disease, worsens mental health and shortens life expectancy.
This is why researchers talk about “social fitness”, a sort of continuous training of relationships. There is no need to overturn your life, but to take care of relationships, dedicate time, pay attention to how the people who really matter are doing. Relationships, like the body, weaken if they are neglected.
The study does not ignore the importance of lifestyle. Physical activity, a balanced diet, no smoking and alcohol in moderation remain fundamental elements for health. But the data shows that they work better when they are part of a rich and stable relational life.
In an era marked by digital connections and frenetic pace, the message that comes from Harvard is surprisingly concrete: a good life is not the perfect one, but the shared one. After more than 85 years, research continues to evolve, also studying the impact of technology on relationships and the role of social policies on quality of life. A simple lesson, perhaps uncomfortable, but very current: happiness is not accumulated, it is cultivated. And it almost always passes through others.
