Increased calls for data sharing have formed part of many governments' agendas to boost innovation and scientific development. Data openness for reuse also resonates with the recognised need for more transparent, reproducible science. But what are scientists' perceptions about data reuse? Renata Gonçalves Curty, Kevin Crowston, Alison Specht, Bruce W. Grant and Elizabeth D. Dalton make use of existing survey data to analyse the attitudes and norms affecting scientists’ data reuse. Perceived efficiency, efficacy, and trustworthiness are key; as is whether scientists believe data reuse is beneficial for scientific development, or perceive certain pressures contrary to the reuse of data. Looking ahead, synthesis centres can be important for supporting data-driven interdisciplinary collaborations, and leveraging new scientific discoveries based on pre-existing data
