This episode explores the increasing number of single adults globally and challenges the societal pressure to marry. Against the backdrop of a world designed for couples, with legal and financial advantages favoring married individuals, behavioral economist Peter McGraw argues that the rise of singlehood, particularly among women, represents progress. More significantly, he points out that correlational data showing higher life satisfaction among married people is misleading, as happier individuals are more likely to marry in the first place. For instance, the "wedding date bump" in happiness is short-lived, and the happiest countries often have high rates of single living, particularly in Scandinavia. McGraw advocates for policies supporting individuals regardless of marital status, such as Sweden's social safety net, and emphasizes the importance of diverse support systems beyond romantic partnerships. Ultimately, he promotes a shift from societal prescriptions to individual choices, celebrating the diverse and fulfilling lives of single people. This challenges traditional notions of family and success, highlighting the importance of individual well-being and diverse life paths.
