In The Coddling of the American Mind, social psychologist Jonathan Haidt analyzes the mental health of teenagers and its decline in many countries worldwide. He highlights the importance of free play, which helps children develop into capable and happy adults. He explains the unfortunate transition from the generations of play to the screen generation, as well as the mechanisms that negatively affect children's psychosocial development, such as:

• Insufficient sleep
• Attention fragmentation
• Addiction
• Loneliness
• Social comparison
• Perfectionism

Haidt also analyzes the reasons why social media affects girls more, while boys resort to the digital world, with serious consequences for themselves and society. Finally, he calls for action from parents, teachers, schools, technology companies, and governments to address mental health issues and return childhood to the human dimension it deserves.
