Monitoring Happy People and Happy Countries During the New Year's Holidays: Methodological Challenges and Paradoxical Data Introduction: The Festival as a Social and Psychological Experiment The New Year's holidays represent a unique time interval for studying subjective well-being (SWB). This is a period when social rituals, cultural expectations, and individual psychological processes interact most intensely. Monitoring happiness at this time is confronted with a classic paradox: the gap between the prescribed social norm of joy ("obligation of happiness") and the real emotional experience, which may include stress, loneliness, and existential anxiety ("holiday blues"). Scientific analysis of this phenomenon requires distinguishing between macro-social data (country rankings) and micro-level psychological measurements. 1. Macro-level: Happy countries and the New Year's "background effect" Annual global happiness rankings, such as the World Happiness Report, which relies on data from the Gallup World Poll and evaluates countries based on GDP per capita, social support, expected life span, freedom, generosity, and perception of corruption, provide a stable picture. Northern European countries (Finland, Denmark, Iceland), Switzerland, and the Netherlands are consistently at the top. Their high scores are due to systemic factors: developed social protection, low levels of inequality, and trust in institutions. The impact of the New Year's period on these rankings is minimal, as they aggregate data over several years. However, the holiday can serve as an indicator of the robustness of these systems.

In contrast, in societies with a high level of individualism and consumerism, the pressure of the commercialized "ideal holiday" may, according to stu ... Read more
