This study aims to clarify third-party intervention preferences and their corresponding reputation evaluations, while also exploring the key factors influencing both intervention and reputational consequences. Utilizing the Mixed Methods Appraisal Tool (MMAT), a comprehensive review of relevant literature published between 2000 and 2024 was conducted. A total of 3,965 studies were retrieved (3,079 in English and 886 in Chinese), of which 59 were initially selected. Following quality assessment, 53 studies met the criteria for systematic analysis. The review revealed that, among third-party intervention preferences, compensation are predominant, whereas punishment exhibit greater situational specificity. When children and adolescents serve as third-party interveners, their preferences demonstrate developmental characteristics. In adult populations, preference differences are largely context-dependent. Thirdparty intervention preference is a complex decision-making process shaped by individual traits, situational factors, sociocultural influences, and physiological-psychological states. Its underlying mechanism lies in the dynamic interaction between empathic concern for justice and cost-benefit trade-offs. Regarding reputational evaluation, the type of intervention plays a pivotal role and generally aligns with the “warmth-over-competence” principle. The mechanism of reputation formation can be conceptualized as a three-stage model: behavior motivation → perceived dimensions → cultural norms. In conclusion, there is a widely observed preference for compensation, which is associated with higher reputational value.
