Second, our study reiterated the importance of clear policies over ownership and control of scientific outputs. For example, researchers want to benefit from their work before broad release (Fecher et al., 2015; Wouters and Haak, 2017). Allowing researchers to exercise reasonable choice over when and how they share, and providing the leeway to adapt practice to different research contexts, may reinforce their trust in open science and promote participation. Consistent with this notion, the MNI policy calls for data release before or on the date of first publication and underlines the principle of autonomy (Figure 1). Notably, while other studies underline researchers’ belief in ownership over data they produced (Fecher et al., 2015; Wouters and Haak, 2017), some of our interviewees suggested that publicly-funded research data and biosamples belong to the public or to patients, rather than the researchers themselves. This perspective may derive from interviewees’ proximity to patients and the needs that open neuroscience seeks to address, or it may be related to the local culture at the MNI (Rouleau, 2017), the local socio-political context or to individual personality differences.
