Are Gritty People Happier than Others?: Evidence from the United States and South Korea

Abstract

Grit, which refers to perseverance and passion to pursue long-term goals, has been highlighted as a predictor of better life outcomes, including subjective well-being. For grit to be useful for well-being research, we need to know more about its properties across cultures and determine whether it has a relationship to well-being outcomes beyond other existing psychological measures. Using survey data from the United States and South Korea (N = 1008), this study examines the measurement of grit across cultures as having two dimensions: perseverance of effort and consistency of interest. It then explores the distinctive utility of grit in explaining an individual’s subjective well-being beyond well-established psychological measures such as conscientiousness and sense of control. The results show that gritty people report better subjective well-being; this positive relationship between grit and subjective well-being is largely driven by the perseverance dimension of grit. This dimension accounts for a unique variance in subjective well-being beyond the sense of control in both country samples and variance beyond conscientiousness in the US sample. By contrast, the consistency dimension of grit adds little to our understanding of subjective well-being in either country. Relying on the global grit score, which aggregates the scores of the two dimensions, may obscure the unique role of the perseverance dimension in understanding subjective well-being.
