The Immaturity of Millennials' Brains: Research Findings

A 2018 study published in The Lancet: Child & Adolescent Health suggests that the definition of adolescence should be extended from ages 10 to 24, rather than the traditional 13 to 19. The study argues that brain development continues into our 20s, and as more people delay milestones like marriage and having children, it may contribute to the perception of millennials as immature. The study also suggests that social media plays a role in this perception, as it exposes the lives of millennials in a more public way. The proposed change in definitions could have implications for laws, social policies, and service systems.
