Reasons for sharing and not sharing data.

Despite the growth of data sharing mandates from scholarly publishers, funding bodies, and other stakeholders, participants more frequently responded that their sharing was motivated by broader reasons, such as a desire to foster reproducibility, transparency, validation, and re-use. “Other” motivations for sharing data included giving other investigators a chance to make discoveries, establishing an open science track record, and as a way to backup data. “Other” reasons for not sharing data included difficulty understanding how data sharing works in the context of tribal agreements and the cumbersome nature of sharing large files.
