The benefits of frequent positive affect: does happiness lead to success?

Sonja Lyubomirsky, Laura King, Ed Diener

Numerous studies show that happy individuals are successful across multiple life domains, including marriage, friendship, income, work performance, and health. The authors propose a conceptual model to explain these findings, arguing that the happiness-success link exists not only because success makes people happy, but also because positive affect engenders success. Three classes of evidence-- cross-sectional, longitudinal, and experimental--are documented to test their model. Relevant studies are described, and their effect sizes are combined meta-analytically. The results show that happiness is associated with and precedes numerous successful outcomes, as well as behaviours that parallel success. Furthermore, the evidence suggests that positive affect--the hallmark of well-being--may be the cause of many of the desirable characteristics, resources, and successes correlated with happiness. Limitations, empirical issues, and important future research questions are discussed.
