The longest-running study of human well-being ever conducted has a clear answer about what makes a life go well. It is not money, status, or health. It is the thing this industry produces. 

What 85 Years of Data Says 

In 1938, researchers at Harvard began following 724 young men, half of them students, half from some of the poorest neighborhoods in Boston. They interviewed them every two years and measured their health every five. The study never stopped. It now follows more than 2,000 people across three generations, and it is directed today by the psychiatrist Robert Waldinger. 

The question was simple: what keeps people healthy and happy as they age? The researchers expected the answer to be wealth, status, or cholesterol. It was none of those. The single strongest predictor of health and happiness in later life was the quality of a person’s close relationships. The people most satisfied with their relationships at fifty were the healthiest at eighty. 

Waldinger summarized the finding in one sentence in his 2015 TED talk, now viewed tens of millions of times: good relationships keep us happier and healthier. His 2023 book with Marc Schulz, The Good Life, adds a second lesson that matters for anyone who runs a company. Relationships are not a fixed asset. They wither from neglect and they strengthen with time spent together. The researchers call this social fitness, and they mean it literally: it has to be exercised. 

In one sentence: in-person meetings matter because the quality of close relationships is the strongest predictor of health and happiness across a lifetime, and relationships are built in time spent together. 

What the Study Does not Say, and What we Conclude from it 

The Harvard study measured personal relationships over a lifetime. It did not measure corporate events, and it would be dishonest to pretend otherwise. What we draw from it is an inference, and we state it as one. 

If the quality of human connection is the strongest predictor of a good life, then any organization that depends on people working well together has a direct interest in the conditions under which those connections form. In our experience, trust is built faster across a table than across a screen. Colleagues who have shared a long dinner in an unfamiliar city return with a working relationship that no number of video calls would have produced. This is not sentiment. It is the mechanism the study describes, applied to a team. 

Why the Argument Matters More Now 

Artificial intelligence is removing cost from the logistics of our industry, and that changes what a company is actually buying when it brings people together. When planning, budgeting, and coordination are automated, the price of a program shifts toward the only part that cannot be: the hours people spend in the same room. That is where the value has always been. The technology simply makes it visible on the invoice. 

The companies that understand this will not spend less on bringing people together. They will spend differently: less on process, more on the quality of the time. Those are the hours the Harvard data point to. 

The Business Case in Plain Terms 

Leaders who defend a budget for meetings, incentives, conferences, and events usually argue from outcomes: alignment, retention, the launch that landed. Those arguments remain valid. The research adds a foundation underneath them. Bringing people together is not a perk that survives a good year and disappears in a hard one. It is the condition under which the rest of the work gets done well. 

The obvious objection is cost, days away from work, and the footprint of travel. The evidence does not argue for more gatherings. It argues for fewer, longer, and better-designed ones, where the time together is protected rather than filled. One well-designed program a year does more for a team than four rushed ones. 

The practical questions then change. The question is no longer whether to bring the team together but how to design the time so that connection actually happens. Fewer plenary hours. More time at the table. Days built around conversation rather than around a projector. That is a design problem, and we have written a separate piece on how to design a program that builds real connection. 

Where a Global DMC Fits 

Ovation Global DMC is the only true global DMC, present in 150+ destinations through wholly owned offices and a Strategic Partner Programme that work to one shared standard. That standard exists for one reason. When a company brings people together far from home, the quality of the human experience on the ground decides whether the investment pays. Local knowledge, local hosts, and local rhythm are what turn a schedule into a memory people carry back to work. 

Our tagline is Making it Happen. The Harvard study gives it a more precise meaning. What we make happen is the time people spend together. 

The next time a budget line for bringing people together comes up for review, the question is not whether the company can afford it. Eighty-five years of evidence say the question is what it costs not to.

FAQ

Why do in-person meetings matter for companies: Because the quality of relationships is the strongest predictor of wellbeing over a lifetime, and relationships form fastest in time spent together. Teams that meet in person build trust that remote work alone does not produce. 

What did the Harvard Study of Adult Development find: Running since 1938, it found that close relationships, not wealth or status, best predict health and happiness in later life. People most satisfied with their relationships at fifty were the healthiest at eighty. 

Does this mean companies should hold more events: No. The evidence argues for fewer, longer and better designed gatherings where time together is protected, not for a higher number of them.
