This document summarizes the results of a 2014 survey conducted by Wiley on researcher data sharing practices, attitudes, and motivations. Some key findings include: most researchers are sharing data, typically files under 10GB like CSV or text files stored locally; common barriers to sharing include concerns about work being scooped or misinterpreted, IP issues, and lack of time or resources; life scientists are most likely to share while social scientists and humanists share least; barriers vary by field and country. The document concludes that recognizing barriers is important to overcome, though some may require community support.
