Money (Does?) Buy Happiness

Among the scheduled sessions for Dialog's August 2026 retreat at the Powerscourt Hotel outside Dublin is one titled "Money (Does?) Buy Happiness." The parenthetical is doing a lot of work. It's coy — the punctuation of people who already know the answer but want to seem like they're still asking.

According to WIRED's verified reporting, the 222 people registered for that retreat include the U.S. Treasury Secretary, multiple billionaire tech founders, a NATO supreme allied commander, and the co-founder of a surveillance company with Pentagon contracts. Registration costs $16,000. The question of whether money buys happiness hits a little different when the people debating it could fund a mid-sized school district with what's in their brokerage accounts.

So let's take the question seriously, since they apparently plan to.

The Old Answer

For over a decade, the conventional wisdom had a tidy ceiling. In 2010, Nobel laureates Daniel Kahneman and Angus Deaton published a landmark study in the Proceedings of the National Academy of Sciences examining roughly 450,000 responses to a daily well-being survey. Their finding entered the popular imagination almost immediately: emotional well-being rises with income, but only up to about $75,000 a year. Beyond that, more money didn't make people feel better on a day-to-day basis. Life satisfaction — how you evaluate your life when you step back and think about it — kept climbing. But the felt experience of a Tuesday afternoon? That plateaued.

It was a comforting result. It suggested a natural limit to the emotional utility of wealth, a point at which the hedonic returns flattened out and everyone was playing on roughly the same field. The implication was almost democratic: past a certain threshold, the billionaire and the senior engineer were waking up to mornings that felt more or less the same.

For obvious reasons, this was a very popular finding.

The New Answer

In 2021, University of Pennsylvania researcher Matthew Killingsworth published a study that said: not so fast. Using an experience-sampling method — an app called "Track Your Happiness" that pinged participants at random moments throughout their day — Killingsworth found that experienced well-being kept rising with income well past $75,000, with no evidence of a plateau.

The two findings contradicted each other directly, which created an interesting problem. Kahneman was perhaps the most cited psychologist alive. Killingsworth had better data. So in 2023, they did something almost unheard of in academic psychology: they collaborated. Kahneman, Killingsworth, and mediator Barbara Mellers published an adversarial collaboration in PNAS that reanalyzed the data together.

Their reconciled finding was more nuanced than either original study. For the unhappiest 20 percent of people, emotional well-being did plateau around $100,000 — roughly the inflation-adjusted equivalent of Kahneman's original $75,000 threshold. More money didn't help them feel better. But for the majority of people, happiness continued to rise with income. And for the happiest group, the association between money and well-being actually accelerated above $100,000.

In other words: if you're already miserable, money won't fix it. If you're already doing okay, money makes it better. And if you're already happy, money makes it much better.

This is not the egalitarian story the 2010 study told.

The Billionaire Answer

Then, in 2024, Killingsworth extended his research to the ultra-wealthy — people with net worths in the millions and billions. By combining his own data with a 2018 study of millionaires and a 1985 Forbes survey of America's richest people, he found that the ultra-wealthy reported average life satisfaction ratings between 5.5 and 6 on a 7-point scale. People earning around $100,000 came in just over 4.5. People earning between $15,000 and $30,000 were just above 4.

The gap between the wealthy and the middle-income group was nearly three times larger than the gap between the middle-income and low-income groups. Killingsworth's conclusion was blunt: the idea that middle-income people are close to the peak of the happiness curve is wrong.

So: money does buy happiness. It keeps buying it well past the point where anyone would consider you financially comfortable. And the people who have the most money report being the happiest.

Case closed?

The Complication

Not quite. Because a different long-running study has been saying something else entirely for 87 years.

The Harvard Study of Adult Development began in 1938 with 724 participants. It has since expanded to roughly 2,500, including spouses and descendants of the original cohort. It is the longest-running scientific study of human health and happiness ever conducted. Its current director, psychiatrist Robert Waldinger, summarized the central finding in a 2015 TED talk that has been viewed nearly 50 million times: good relationships keep us happier and healthier. Period.

Not money. Not fame. Not career achievement. The people who were most satisfied in their relationships at age 50 were the healthiest at age 80. Loneliness, the study found, was as powerful a predictor of early death as smoking or alcoholism.

What Waldinger's research measures is different from what Killingsworth's measures. Killingsworth asks how you feel right now, several times a day, then correlates it with your income. Waldinger follows people across their entire lives and asks what actually predicted whether they thrived or deteriorated. One measures the texture of a good afternoon. The other measures the architecture of a good life. They are not measuring the same thing, and the distinction matters enormously.

It is entirely possible — the research supports this — that billionaires have better Tuesdays and worse lives. That money reliably improves the quality of any given moment while doing nothing to address, and perhaps even undermining, the relationships that determine whether those moments add up to something meaningful.

The Isolation Paradox

Clinical psychotherapists who work with the ultra-wealthy report a pattern that the happiness research doesn't fully capture. According to therapists interviewed by CNBC, the super-rich frequently struggle with chronic isolation — not because they lack social contact, but because they can never be certain whether people value them or their resources. Relationships become defined by what the wealthy person can provide rather than who they are.

This is not a new observation. What's new is the scale. When your net worth attracts an entourage, the infrastructure of genuine connection erodes. The wealthier you are, the harder it becomes to have a relationship that isn't, at some level, transactional.

Psychologists describe this as a trust paradox: extreme wealth provides the resources to do almost anything, but it simultaneously introduces uncertainty into every human interaction. The result, according to research from the University of California, Berkeley, is that people with higher incomes may become less reliant on social bonds — not because they don't need people, but because the cost of trusting the wrong person is higher when you have more to lose.

Hedonic adaptation compounds the problem. The "hedonic treadmill" — the well-documented tendency of humans to return to a baseline level of happiness regardless of positive life changes — spins faster for people who can acquire virtually anything on a whim. When everything is available, the satisfaction of attainment itself diminishes. You adapt to the yacht faster than you adapted to the used car, and the emotional return on the next purchase shrinks accordingly.

The $16,000 Question

Which brings us back to that Dublin hotel room.

Two hundred and twenty-two people, paying $16,000 each, gathering for off-the-record conversations at a luxury estate. According to WIRED's reporting, the agenda includes sessions on world war, battlefield technologies, cult-building, and — tucked in among the geopolitics — whether money buys happiness.

The question is not academic for this crowd. It's autobiographical.

These are people who have tested the hypothesis to its limits. They have the data set. They have the income that Killingsworth's research says should produce life-satisfaction scores between 5.5 and 6 out of 7. They also inhabit the exact social environment that Waldinger's 87-year study says matters more than any of it — except theirs is mediated by NDAs, off-the-record rules, and $16,000 admission fees.

Dialog's own participation guide, according to leaked materials, tells members to avoid status signaling. It stresses that attendees should never argue for the sake of winning. It assigns seating. It optimizes for introverts. Read one way, these are the ground rules of a thoughtful intellectual community. Read another way, they are the behavioral architecture of people who have so much status that they need explicit rules to stop performing it.

The question the session title asks — Money (Does?) Buy Happiness — is interesting. But the more interesting question might be the one the structure of Dialog itself answers: when you have more money than you could spend in a lifetime, what do you buy with it?

According to the leaked registration list: a seat at a table where the Treasury Secretary, the co-founder of Palantir, and a NATO commander are having breakfast together. Off the record.

Maybe money doesn't buy happiness. Maybe it buys something these particular people find more valuable: the room where the future gets decided, and the confidence that you'll be in it.

Whether that constitutes happiness is, as the parenthetical suggests, an open question.
