Open Science has been turned into a global movement with rising number of countries mapping out their routes towards science systems that are more open, inclusive, and accessible (UNESCO, 2023). However, it is now well established that the transition to open science and reaching its full potential requires a shift in the culture of and partnerships for science (UNESCO, 2023); a cultural shift towards reforming scientific communities so that they embrace more collaboration rather than competition. While the shift in research culture can be a unique journey for individuals, Ph.D. students as newcomers in scientific communities can be influenced by their supervisors’ mindsets and practices such that restrictions and/or a lack of incentives on open practices by supervisors is among the most frequently mentioned barriers throughout the open science life cycle (Gownaris et al., 2022). Haven et al., (2023) found that when a Ph.D. candidate works with a supervisor who shares data, the likelihood of the candidate also sharing data increases. These researchers believe that even when a Ph.D. student is knowledgeable about open science practices at the beginning of her/his Ph.D. journey, having a supervisor who role models these practices can be helpful (Haven et al., 2023). Given the significant influence of supervisors on Ph.D. students and the critical importance of open science, fostering a dynamic dialogue among supervisors to share their experiences and discuss current developments is essential for realizing full potential of open science.
