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., , # Data from: Conflicting identities and cooperation between groups: Experimental evidence from a mentoring program Associated article: Antonio M.
