We hope to encourage autism journals to adopt registered reports as a means to publish academic research. You can find our letter as a pdf in the Files on this project page. This includes a version added on the 12th of May, with over 100 signatories in support. To add yourself as a signatory, your name to the Google documents, also in the Files (called "CLICK HERE TO SIGN_Signatories for RR in autism research" - click on the document, and open in Google Drive to add your name to the bottom of the Table). The "final" letter with signatories will be documented on this OSF page and shared with the journals listed in the letter. We will aim to do this at the start of May, depending on the level of support the letter receives. Please note **if you add your name to the Google Doc, this will be on the published letter.** Researchers from all career stages are welcome to add their names. If you have any questions about this initiative, please contact Hannah Hobson (hannah.hobson@york.ac.uk)
