Criminal behaviour is shaped by a web of economic, social and environmental factors — and researchers across disciplines are working to untangle it. A new feature from Nature highlights the experiences of three scholars who study the systems of crime and punishment, offering rare insights into the human realities behind criminal-justice research.
Globally, more than 11 million people are incarcerated, with numbers rising in many regions. Conditions vary dramatically: daily government spending per prisoner ranges from around €13 (US$15) in Bulgaria to €532 in Norway. Overcrowding, lack of medical care, and stark inequalities in rehabilitation programmes continue to fuel debate on the effectiveness of justice systems worldwide.
But beyond statistics, the stories of those who research crime shed light on its deeper complexities.
The pendulum of support
Sociologist Sadé Lindsay of Cornell University examines how U.S. criminal-justice policies affect opportunities and health outcomes for people with records, particularly in the context of drug-diversion programmes. Despite being designed to provide treatment instead of jail time, these alternatives are disproportionately inaccessible to Black and Hispanic populations. “Political support for prison reform can swing like a pendulum,” Lindsay says. “Our role as researchers is to keep doing the work and collecting the evidence, even when the political winds aren’t blowing in our favour.”
Listening to lived experience
For criminologist Kanupriya Sharma at the University of Nottingham, fieldwork with women incarcerated in India revealed surprising narratives. Instead of focusing only on trauma, many women emphasized love and relationships forged during imprisonment. Her work underscores how incarcerated women challenge both prison systems and patriarchal norms. Sharma also founded the Cambridge Decolonising Criminology Network to amplify perspectives from the Global South. “Your gut instinct is your strongest tool,” she reflects, noting the importance of cultural knowledge and reflexivity when navigating emotionally charged fieldwork.
Restorative justice in practice
At the Australian National University, criminologist Ian Yan Zhang studies restorative justice — an alternative approach that emphasizes repairing harm over punishment. In China, millions of cases are settled annually through community-led mediation committees. Zhang’s research, however, reveals the tensions between the ideals of restorative justice and its bureaucratic realities. His academic journey — from forensic science to criminology — reflects an evolving understanding that crime cannot be solved by evidence or punishment alone.
Together, these accounts illustrate the challenges and rewards of working in criminal-justice research. From navigating political shifts to balancing objectivity with empathy, the work requires persistence, cultural awareness, and strong networks. As Nature’s report shows, the voices of researchers are vital in shaping how societies understand crime — and how they imagine justice.
