Does the shape of a body shape a life?

In 1956, Harvard criminologists Sheldon and Eleanor Glueck published one of the most provocative findings in the history of criminology: among the 500 persistent juvenile delinquents at the heart of their landmark study, six in ten were built like athletes — solid, muscular, "mesomorphic" — compared to fewer than one in three of the matched non-delinquent boys from the very same streets. Boys of slight, fragile build were strikingly rare among the delinquents. Matched for age, intelligence, ethnicity, and neighborhood, the two groups differed sharply in one thing neither had chosen: the body they were born with.

Physique and Delinquency is the Gluecks' full investigation of what that difference meant — and what it didn't. Carefully, methodically, and explicitly rejecting the old "born criminal" theories of the nineteenth century, the Gluecks set out to show that physical constitution is not destiny. Instead, they found something more nuanced and more interesting: the very same trait, and the very same troubled home, can push a sturdy, energetic boy toward trouble while leaving a more sensitive, delicately built boy untouched — and can devastate that same sensitive boy when the pressures at home turn severe.

This Read-Me.Org Mini-Classic distills the Gluecks' densely tabulated 1956 original into a compact, readable narrative — every chapter, every major finding, and the six theoretical hypotheses that close the book — while leaving the statistical tables and technical appendixes to specialists and to the full edition. It's an ideal introduction for students of criminology, psychology, and the history of science, and for anyone curious about a study that remains as influential as it is uncomfortable, nearly seventy years after it first raised the question.

Includes a new introductory essay situating the book in its historical context, and a set of review and discussion questions suited to classroom or book-club use.

Part of the Read-Me.Org Mini-Classics series — short, careful introductions to landmark and forgotten works of criminology, sociology, and social history.

The focus of this Policy Note is specifically on the role of women and girls in gangs as an opportunity to examine whether a more “gendered” response to the phenomenon of gangsterism could have success. The case study for the research was the gangs of Cape Town, a city not only with a historical problem of gangs, but one where recent trends have showed a dramatic upswing in violence, both within and between gangs. Cape Town was chosen largely because it offered the possibility, through the network of the Global Initiative and its links to the University of Cape Town, for interviewing female gang members in a way that would have been difficult to achieve elsewhere. Cape Town now displays violence - at a level of 60 homicides per 100,000 residents for 2015/16 – that is consistent with many cities in Latin and Central America that have had longstanding challenges with gangs. In Cape Town, violence is closely linked to changes within the city’s drug economy in marginalised areas, and the introduction of a flood of firearms (ironically many from police stores) from 2010. This has exacerbated conflict between gangs and increased the ability of smaller and new gangs – who have obtained access to weapons – to both enter and expand their drug operations. The result is a fluid and violent environment, although this is generally confined to previously marginalised so-called ‘coloured’ or mixed race areas of the city. It goes without saying, however, that the human cost and suffering has been enormous, with some parts of the city having homicide rates of over 100 deaths per 100,000 people with innocent bystanders, including children, often caught in the crossfire.
