Dear colleagues,‎

We are conducting a meta-analysis on methods and results of situational activation of global social identities (global human identity, global citizenship identity, etc.). We would like to ask for your help with gathering published and unpublished studies for the meta-analysis process.‎ We are interested in any of the following situations:

when global identity was used as manipulation and/or when another manipulation was used to change the level of global identification.

We would appreciate references to any published data on this issue to make sure we have included them in our meta-analysis. More importantly, we are especially interested in any relevant unpublished manuscripts or unpublished ‎data that cannot be found through a regular literature search.

If you have unfinished or unpublished manuscripts, we would appreciate a copy. These will be kept ‎confidential and will not be used for any other purpose other than inclusion in the meta-analysis (with a reference).

If you only have raw data that has not yet been analyzed, then we would be happy to help analyze it in exchange for ‎inclusion (with a reference). In such a case, please send us the dataset and a description of the key variables, relevant for the analysis.‎

Please send all relevant information and/or data to us at this email [email protected] or [email protected] by the end of April. If you have doubts, whether your study meets the criteria, please contact us as well.

Please, pass this request to any colleagues who might be conducting relevant research. Thank you for your help.

Kind regards,‎
