Following an article in the New England Journal of Medicine, which portrayed scientists who re-use data as parasites, we now hear more on this from Nature.

When comparing the published results of survey experiments with the pre-registered plans for the same study, a lot of information gets lost. 80 percent of the studies failed to report all experimental conditions and planned outcomes.
