"Unraveling Juvenile Delinquency" by Sheldon and Eleanor Glueck is a comprehensive study on juvenile delinquency, based on a ten-year research project involving 1,000 boys from Massachusetts. The study used various methods to analyze delinquents and non-delinquents, including psychological tests, medical examinations, and social background assessments. The Gluecks found that delinquents had specific traits, such as being muscular, restless, and hostile, and they attributed these traits to a combination of physical and psychological factors. However, the article criticizes the study for oversimplifying the causes of delinquency, arguing that it's not just individual traits but also the social context that plays a crucial role. Despite these criticisms, the book is still considered a valuable resource for understanding juvenile delinquency. The second part of the article reviews "Eighty-Thousand Adolescents," a study on youth in Birmingham, which reveals a concerning lack of enthusiasm for school and a sense of aimlessness among young people. The study highlights the need for more engaging educational and social environments for adolescents."Unraveling Juvenile Delinquency" by Sheldon and Eleanor Glueck is a comprehensive study on juvenile delinquency, based on a ten-year research project involving 1,000 boys from Massachusetts.
