Meta-analysis on violent and nonviolent social movements

Call for studies

Bernhard Leidner, Michael Wohl, Nassim Tabri, and I are conducting a meta-analysis on the effects of nonviolent (vs. violent) strategies adopted by social movements on people's attitudes toward supporting and/or joining the movement. The inclusion criteria for the meta-analysis are:

  1. Studies in which human participants are the unit of analysis. (There are sociological studies that have used violent and nonviolent campaigns as the unit of analysis. These studies are not included in our analysis)
  2. Studies that employ experimental, quasi-experimental, correlational, cross-sectional, or longitudinal designs are included.
  3. Besides published work, unpublished work such as manuscripts in press, in the review process, or in preparation, as well as dissertations will also be included.
  4. Work written up in languages other than English will be included if the authors of that work can provide us with necessary information needed for meta-analysis.

We would greatly appreciate it if you could share any studies that fit these selection criteria. We would also appreciate it if you could circulate this request to your networks or any colleagues who may be able to assist.

To share any studies/work, or if you have any question about sharing data for the purpose of this meta-analysis, please email Nima Orazani at

Kind regards,
Nima Orazani, Nassim Tabri, Bernhard Leidner, & Michael Wohl
