The long tail and dark data for traumatic brain injury (TBI) research. The current state of TBI data consists of a relatively small number of large, publicly accessible datasets reflected schematically as a right-skewed distribution (Panel a). The majority of data collected by the field exists in the long tail of the distribution, with most datasets consisting of relatively modest data sizes as either gray data that are difficult to access beyond summaries reported in publications; or dark data that are inaccessible or archived. b The goal is to make TBI imaging data Findable, Accessible, Interoperable, and Reusable (FAIR, Wilkinson et al., 2016) thereby shortening the long tail of dark data, and making a greater proportion of the data in the TBI literature publicly accessible to drive new discoveries and accelerate translation.
