How do the Open Science Badges work?
The Open Science Badges are simple visual indicators that a publication or project followed open practices. Kidwell et al. (2016) describe the badges and their underlying motivation, and show that the rate of openly archived data increased dramatically after their introduction at Psychological Science, as did the proportion of openly available materials.
The badges indicate preregistration of a project's design and analysis, the presence of open data and the open availability of materials. There is also a protected access open data badge for critical data that is placed in a repository, yet are only accessible following a standardized authorization procedure. Preregistration plus indicates the presence of an analysis plan that corresponds directly to the reported analysis.
