To start each interview, we collected demographic information to facilitate comparative analysis across interviews. We then asked open-ended, semi-structured questions to explore individual experience and knowledge. In qualitative research, the dataset is considered complete when a point of theoretical saturation is achieved—meaning no new major ideas, information or themes are emerging from interviews (Morse, 1995). Participant recruitment continued until we reached this point, and with consideration for achieving balanced representation across gender and research area. In total, we conducted 21 interviews with MNI researchers and staff in the first phase. In the second we interviewed four MNI researchers, and three external participants as described in ‘Study sample’, resulting in 25 interviewees in total.
