(firmly on one side of the fine and yet distinctly perceptible line between "I've got mine; fuck you" and "I've got mine, and I hope that you get yours, but I'm far too ignorant of the relevant sciences to say which interventions would make this more or less likely")
It's possible for those ignorant of the relevant sciences to furnish information useful to others. For an extreme example, consider the case of lab rats. Or lab humans.
I hope I'm not missing the point ... the dilemma is simply which sentiment is more likely to help me "get mine"? Seems to me to be situational.
