An amazing article that highlights some of the trends we see in 20 somethings and questions if their brain development has something to do with it.
Although Arnett primarily studies how society, culture and the economy have created emerging adulthood, some scientists and journalists have wondered whether biology is involved as well. Henig writes that some researchers think a lengthy preamble to adulthood might be “better-suited to our neurological hard-wiring” and that the general ambivalence of twenty-somethings—feeling that they are sort of adults, but not really adults— “reflects what is going on in the brain, which is also both grown-up and not-quite-grown-up.” Most recently, The Wall Street Journal ran an article recommending that concerned parents of twenty-somethings should “chill out” because “recent research into how the brain develops suggests that people are better equipped to make major life decisions in their late 20s than earlier in the decade. The brain, once thought to be fully grown after puberty, is still evolving into its adult shape well into a person’s third decade, pruning away unused connections and strengthening those that remain, scientists say.”
