We describe the data management bylaws for the Psychological Science Accelerator (PSA), a distributed network of laboratories dedicated to completing large-scale collaborative behavioral science projects. Our bylaws are organized around the principles of ethical data use, security, accuracy, usability, transparency. We describe how these embodied throughout the lifecycle of a PSA project, from project proposal to data release. In addition to setting up the policies and guidelines for the management of PSA data, we hope this document can provide a useful best practices for individual researchers thinking about the management of their own behavioral science data.
