The conceptual foundation of the study rests on a long-standing distinction in psychology between hedonic and eudaimonic approaches to well-being. Life satisfaction, the single-item or short-scale measure familiar from the Gallup World Poll and the Cantril ladder, is a hedonic evaluative judgment: respondents rate their current life as a whole against an imagined ideal. Eudaimonic well-being, by contrast, concerns optimal human functioning—purpose in life, personal growth, autonomy, mastery, positive relationships, and social contribution. Social well-being extends this further, capturing the quality of one’s ties to community and society. Decades of research, beginning with Carol Ryff’s multidimensional model of psychological well-being and Ed Diener’s foundational work on subjective well-being, have established that these constructs overlap but are not reducible to one another. Joshanloo’s study is the first to bring all three strands—affective, eudaimonic, and social—together into a single national index spanning such a large and diverse set of countries.

The methodological challenge was considerable. Building a comparable index across 116 countries requires item-level data that are measured consistently across languages, cultures, and survey contexts. Joshanloo drew on secondary data from large international surveys, including the Gallup World Poll, and applied modern psychometric techniques to identify a coherent set of indicators spanning positive and negative affect, eudaimonic functioning, and social well-being. Missing data were handled with advanced imputation methods, specifically the random-forest-based approach implemented in the missRanger package, which builds on the earlier MissForest algorithm for non-parametric imputation of mixed-type data. Exploratory structural equation modeling, a factor-analytic technique that allows indicators to load on multiple factors simultaneously, was used to construct and validate the index without forcing artificial simplicity onto a multidimensional construct.

The headline finding is a study in empirical divergence. Psychosocial well-being was positively associated with current life satisfaction, as one would expect from two measures of related but non-identical constructs. Yet when national wealth—typically operationalized through gross domestic product per capita—entered the analysis, the two measures behaved very differently. Life satisfaction, consistent with a vast body of happiness economics research, tracked national income closely. The psychosocial index did not. Its association with wealth was substantially weaker, suggesting that the psychological and social resources people draw on for flourishing—meaning, purpose, connection, competence—are not simply a by-product of economic output.

This divergence produces striking country-level patterns. Some low-income countries scored higher on psychosocial well-being than their life satisfaction figures alone would predict, indicating reserves of psychological and social flourishing that standard rankings fail to register. Conversely, some high-income countries showed the opposite pattern: impressive life satisfaction scores accompanied by comparatively modest psychosocial well-being. In other words, a wealthy nation where people rate their lives favorably on a ladder question may not, on closer inspection, be a nation where people experience strong purpose, mastery, and social integration. The study does not name specific countries in its abstract, but the supplementary material published with the article provides the full national scores, allowing researchers and policymakers to examine where these mismatches occur.

Why does life satisfaction track money so faithfully while psychosocial well-being does not? The study situates itself within an ongoing debate. The influential work of Daniel Kahneman and Angus Deaton suggested that income improves people’s evaluation of their lives but has a much weaker effect on their day-to-day emotional well-being—a dissociation that anticipates Joshanloo’s cross-national findings. More recent research has raised a further concern: the Cantril ladder itself, the response format used in many global surveys, may prime respondents to think about material success, power, and wealth, thereby embedding an economic frame into the very measurement. If the question evokes prosperity, then it is unsurprising that richer countries top the resulting rankings. An influential 2024 analysis published in Scientific Reports found that the ladder elicits thoughts about power and wealth, lending empirical weight to this critique.

There are also deeper cultural and philosophical issues at stake. Evaluative life satisfaction judgments are known to vary across cultures in how people interpret and report them, and researchers including Michael Bond have argued that the pan-cultural assumption that well-being means the same thing everywhere requires careful scrutiny. Collectivist societies, where identity and value are bound to family and community, may express flourishing in ways that an individual-focused evaluative question fails to capture. Eudaimonic and social indicators, by probing purpose, contribution, and relational quality, offer a broader lens. Prior work by Joshanloo, including a 2018 index of eudaimonic well-being across 166 nations, had already suggested that optimal functioning follows a partly independent geography from evaluative happiness; the new study consolidates and extends that program by integrating the social dimension.

The policy implications are significant. International bodies, including the OECD through its guidelines on measuring subjective well-being, have progressively endorsed multidimensional assessment, yet the headline rankings that capture public and political attention remain overwhelmingly evaluative. If life satisfaction functions largely as a wealth proxy, then rankings built on it risk what Joshanloo describes as bias against low-income countries: nations whose material poverty masks genuine psychological and social strengths are systematically undervalued, while affluent nations receive an unexamined halo. A well-being dashboard that includes both life satisfaction and psychosocial indicators would paint a fuller and fairer picture, and could redirect attention toward the social conditions—trust, belonging, purpose—that support flourishing irrespective of income.

The study also speaks to a broader movement to move beyond gross domestic product as the default measure of national progress. From the genuine progress indicator literature to the World Happiness Report’s evolving methodology, researchers and institutions have increasingly recognized that economic aggregates and single evaluative questions are insufficient tools for understanding human welfare. Joshanloo’s psychosocial index, grounded in the hierarchically structured models of well-being developed by Gallagher, Lopez, and Preacher and the integrative perspectives of Ryff and her collaborators, offers a technically robust addition to this toolkit. Its construction using ESEM and rigorous imputation methods addresses two chronic weaknesses of cross-national indices: the tendency to oversimplify multidimensional constructs, and the distortion introduced by incomplete data.

The work, published on 28 September 2026 and supported in part by a grant from the Well-being for Planet Earth Foundation, arrives at a moment when governments and international organizations are actively debating how well-being should inform public policy. Its central message is neither that life satisfaction should be abandoned nor that money does not matter, but that the two existing pillars of national measurement—economic output and evaluative happiness—are too correlated with each other to be jointly informative. A third pillar, psychosocial well-being, breaks that correlation and reveals flourishing where the ladder question cannot see it. For the low-income countries whose strengths have been obscured, and for the wealthy countries whose populations may be rating their lives better than they are living them, that new perspective could reshape how national progress is understood and pursued.
