Conflicting identities and cooperation between groups: Experimental evidence from a mentoring program

We experimentally investigate cooperation in 14 centres of a mentoring program where participants have two possible natural identities—individuals raised under legal guardianship, suffering a negative stereotype (G; n=112) and users without such a social stigma (NG; n=82). Participants played a Prisoners’ Dilemma game with an anonymous partner from the same centre (centre-ingroup) and from another centre (centre-outgroup). The folder contains the raw data in csv and dta (STATA) format and the script (STATA do file) used to define all the variables used and conduct all the analyses reported in the article. The analyses in the script appear in the exact order of appearance in the text, starting from the Methods section and then the Results section.

本研究通过实验探究了一项导师计划的14个中心内的合作行为。该计划的参与者具备两种自然身份：其一为受法定监护抚养、背负负面刻板印象的个体（记为G组，样本量n=112）；其二为无此类社会污名的个体（记为NG组，样本量n=82）。所有参与者将与匿名搭档开展囚徒困境博弈（Prisoners’ Dilemma game），搭档可来自同一中心（中心内群体），亦可来自其他中心（中心外群体）。本数据集文件夹包含csv与dta（STATA格式）两种格式的原始数据，以及用于定义所有研究变量、执行论文中报告的全部分析流程的STATA do脚本文件。脚本内的分析顺序与论文文本的呈现顺序完全一致，从方法学章节起始，随后依次推进至结果章节。
