What distinguishes iGen from prior cohorts is not any single trait but a constellation: elevated anxiety and depression, diminished self-reported agency, reduced face-to-face social interaction, delayed developmental milestones, lower intrinsic motivation, and the specific psychological profile produced by adolescence conducted primarily through screens. iGen is not a pathologized generation — many of its members are thriving, and the cohort shows genuine strengths in tolerance, pragmatism, and safety-consciousness.
