The U-Shape of Happiness: A Response.

We write in response to an article published in this journal, "The U Shape of Happiness Across the Life Course: Expanding the Discussion," by Galambos, Krahn, Johnson and Lachman. The authors claim that "support for the purported U shape is not as robust and generalizable as is often assumed" and "we believe the conclusion that happiness declines from late adolescence to midlife (the first half of the U shape) is premature, and possibly wrong." We respectfully disagree. The authors' main evidence is based on summaries of 33 articles; they find 12 to have U shapes, seven to have none, and 14 to be mixed. We found that most of these articles are misclassified: Four of them are ineligible for inclusion, 25 find a U, and four are mixed. We then identified a further 353 articles, including 329 in peer-reviewed journals, that all found U shapes that were not identified in the literature review. This is a major omission. We also present our own evidence of midlife nadirs in well-being using around eight and a half million individual observations from nationally representative surveys for the United States and Europe. The midlife low occurs in the mid-40s and its drop is equivalent to roughly three quarters of the unprecedented drop observed in well-being during the COVID-19 pandemic.
