我们发现，许多非认知技能和偏好，包括耐心和认同感，在成年人身上是可塑的，对它们的投资可以减少犯罪和暴力。我们招募了从事犯罪活动的男性，并随机进行了半到八周的认知行为治疗，旨在培养自我调节、耐心和非犯罪身份和生活方式。我们还随机分配了200美元的赠款。最初，仅靠现金和治疗就能减少犯罪和暴力，但随着时间的推移，影响会消失。当治疗后有现金时，犯罪率和暴力行为至少在一年内大幅下降。我们假设现金通过延长边做边学、改变生活方式和自我投资来强化治疗的效果。
We show that a number of noncognitive skills and preferences, including patience and identity, are malleable in adults, and that investments in them reduce crime and violence. We recruited criminally engaged men and randomized one-half to eight weeks of cognitive behavioral therapy designed to foster self-regulation, patience, and a noncriminal identity and lifestyle. We also randomized $200 grants. Cash alone and therapy alone initially reduced crime and violence, but effects dissipated over time. When cash followed therapy, crime and violence decreased dramatically for at least a year. We hypothesize that cash reinforced therapy's impacts by prolonging learning-by-doing, lifestyle changes, and self-investment.
