A growing body of research highlights a marked decline in conscientiousness among young adults aged 16 to 39, a personality trait essential for personal and societal success. Studies indicate that this decline is accompanied by increases in neuroticism, reduced extroversion, and diminished attentional capacity, factors that collectively undermine young people's ability to succeed in work and life. Experts and commentators attribute these changes largely to the pervasive use of smartphones, social media platforms like TikTok and Instagram, and the consumption of short-form video content, which are linked to deteriorating brain focus and mental health challenges. The trend raises concerns about the long-term societal implications as younger generations exhibit increased disorganization, negative emotions, and reduced well-being. Additionally, there is growing apprehension about young people relying on social media for mental health self-diagnosis instead of professional care. These findings underscore the urgent need to address the cognitive and psychological effects of modern digital technologies on youth.
