I only hope that it isn’t simply that people lose their drive to be open as the realities of professional research hit post-graduation.

That's where you and Jean-Claude, and more senior people like Jonathan Eisen, Rosie Redfield etc, come in! Even me, though I am but an egg (mere postdoc).

You are absolutely right about the younger scientific "generation" -- look at open theses (Gunn, Piwowar, Csordas), open notebooks (Faith). Talk to any grad students you can find, and compare the response to Open Science advocacy with the kind of response that one tends to get from established researchers (e.g., ""Open notebook" science is a ridiculous joke").

So, it is imperative that anyone in a position to do so, should give up-and-coming scientists the opportunity to put as much of their work in the open as they want to. That's why I think the ONS-friendly labs list is such a terrific idea. I'm snowed under with work and immigration issues right now, but I shall champion that list just as hard as I can once I return to regular blogging.
