The RRBM course or one like it should be part of every PhD education, and I am confident I am a better researcher (and person!) for the experience.
As a PhD student often in a cultural and research bubble at the intersection of my region (Europe) & discipline (International Business), this experience with peers from all over the world allowed me a rare opportunity to exchange ideas outside this silo.
Not only that, over the course of 10 sessions we formed bonds based in care and shared values—particularly, the importance of responsible research—defining a network which I know will last well beyond the end of the course.
Equally valuable was the encouragement to work through challenging yet mind-expanding material on the philosophy of (social) science. These were much better digested by talking through them with peers, through discussions and even debates!
