Core Viewpoint - The pursuit of happiness is often overshadowed by more concrete and realistic aspects such as family health, life security, and financial stability, rather than happiness itself [1][2]. Group 1: Research Findings - The study found that "children's health" has a marginal utility 67 times the average, indicating that respondents are willing to make significant sacrifices for even a slight improvement in their children's health [2]. - Other top welfare dimensions include "children's happiness," "ability to provide economic support for the family," and "personal health," while "life satisfaction" has a marginal utility of only 1.6-2 times the average, indicating a lower priority [2]. - The research suggests that happiness is not the ultimate goal but rather a byproduct of fulfilling responsibilities, health, and stability [2]. Group 2: Philosophical Perspectives - Historical perspectives from philosophers like Aristotle and Mencius align with the study's findings, emphasizing that happiness arises from a life of virtue and moral integrity rather than mere sensory pleasure [3][4]. - Both Western and Eastern philosophies converge on the idea that happiness is achieved through the realization of moral values rather than the accumulation of emotional gratification [4]. Group 3: Individual Preferences - The study highlights that individual preferences are shaped more by personal experiences, resources, and mental states than by demographic factors such as age, gender, or income [4][5][6]. - Personal experiences, including childhood environment and significant life events, significantly influence what individuals prioritize in life [5]. - Resources such as wealth, health, and social relationships determine the potential for achieving various welfare dimensions, affecting how individuals perceive value in different aspects of life [5]. Group 4: Psychological Factors - A person's cognitive state, including their emotional regulation and comparison mechanisms, profoundly impacts their happiness experience [6]. - There is often a discrepancy between what individuals claim is important and what they are willing to sacrifice for it, indicating that subjective happiness is a result rather than a goal [6][7]. - The study concludes that when individuals focus on stability, close relationships, and health, happiness naturally follows, rather than being a direct pursuit [7].
