Kierkegaard saw the problem clearly in the 1840s, but modern culture has since built an entire scaffolding that makes his predictions worse. Anthropologist Arnold van Gennep identified that rites of passage universally involve separation, liminality (in-between), and reentry with a new identity. Victor Turner showed that modern culture eliminated the ritual but preserved the liminal phase indefinitely. [1] — Drew Birnie "Median marriage age rose 6–8 years per gender since 1970s: Median age at first marriage climbed from 21 (women) and 23 (men) in the 1970s t…" 56:15 Jeffrey Arnett formalized this as 'emerging adulthood' — the exploratory, identity-uncertain decade that barely existed before the mid-20th century. Drew walks through the numbers: marriage age up 6–8 years per gender since the 1970s, college enrollment up from 14% to 60%, first childbirth age steadily climbing. Separately, Zygmunt Bauman's 'Liquid Modernity' identified how a dynamic service economy made commitment an economic liability — skills became transferable, careers became portfolios, and the return-policy mindset spread from products to relationships. The result is a low-trust environment where commitment feels not just uncomfortable but strategically unwise.
More connectivity doesn't produce more independent thinking — it produces more homogeneity. Kierkegaard called this 'leveling': the internet's utopian promise of everyone thinking for themselves is backwards. The more interconnected people are, the stronger the phantom of public opinion, and the more of a liability it becomes to stand out.
Traditional societies had rites of passage that closed off childhood and opened adulthood. Modern society kept the in-between liminal phase but eliminated the ritual that resolved it. The result is 'emerging adulthood' — a decade or more stuck in the transition — engineered by rising education requirements, women entering the workforce, and delayed marriage.
Median age at first marriage climbed from 21 (women) and 23 (men) in the 1970s to nearly 29 (women) and 30 (men) today — a rise of 6–8 years per gender, extending the 'emerging adulthood' liminal phase.
