UK researchers are becoming slightly more open in their data sharing practices over recent years. Younger researchers and those at earlier career stages are more likely to engage with open data sharing tools like blogs and wikis. However, many researchers remain reluctant to openly share their data due to concerns about intellectual property, inappropriate use, and lack of reward. Recommendations to promote open data practices include developing infrastructure and skills training, establishing policies on data sharing, and providing recognition and incentives for researchers who engage with open science principles.
