Meta-analysis on Experimental Effects of Collective Narcissism

Dear Colleagues,

We are conducting a meta-analysis on experimental attempts to directly manipulate collective narcissism. Our own attempts to induce this construct have met with limited success, and we aim to compile a comprehensive summary of experimental methods to better understand what works and what does not. We believe this will make an important methodological contribution to the study of collective narcissism.

We are seeking studies that meet the following criteria:

(1) Independent Variable: Direct manipulation of collective narcissism.
(2) Manipulation Check: A quantitative measure of collective narcissism.
(3) If Applicable: A quantitative measure of ingroup identification.
(4) If Applicable: A quantitative measure of outgroup prejudice, threat perception or conspiracy beliefs.

If you have manuscripts or data that meet the above criteria and are willing to contribute to our meta-analysis, please contact us at paul.bertin@ulb.be for further guidance.

Thank you in advance for your assistance!

Best regards,
