	|  |  |  | Dear Colleagues,
 
 We are working on a meta-analysis of the effect common ingroup identity on intergroup attitudes and behavior. We are currently looking for any unpublished studies, data sets, or “in press” papers that include either a manipulation or measurement of common identity (or dual identity) and one or more of the following outcomes: intergroup bias, outgroup attitudes, prosocial behavior, discrimination, etc.
 
 In order to be able to use the information in the meta-analysis, I need to be able calculate effect sizes, so I would need things like correlations, Cohen’s d, or means and SDs, etc.
 
 Anything that you think might be relevant can be sent to bmr2@calvin.edu .
 
 Thanks.
