To foster openness and transparency in the psychology of religion and spirituality (PRS), together with the joint editors of 3 PRS journals, we have launched a Call for Proposals. This project will fund the publication of 18 studies that will be conducted in the format of a Registered Report. This publishing format allows one to submit a paper prior to collecting data, so that one can benefit from peer-review prior to conducting the study. The results of the study will then be published, irrespective of whether the hypotheses were confirmed or not.
