As incarceration rates rise globally, the need to reduce re-offending grows increasingly urgent. We investigate whether positive group bonds can improve behaviours among incarcerated people via a unique soccer-based prison intervention, the Twinning Project. We analyse the effects of participation compared to a control group (study 1, n = 676, n = 1,874 control cases) and longitudinal patterns of social cohesion underlying these effects (study 2, n = 388) in the United Kingdom. We also explore desistance from crime after release (study 3, n = 249) in the United Kingdom and the United States. As law-abiding behaviour also requires a supportive receiving community, we assessed factors influencing willingness to employ formerly incarcerated people in online samples in the United Kingdom and the United States (studies 4–9, n = 1,797). Results indicate that social bonding relates to both improved behaviour within the prison and increased willingness of receiving communities to support reintegration efforts. Harnessing the power of group identities both within prison and receiving communities can help to address the global incarceration crisis.
