I agree that we sometimes need to (voluntatily) commit to extreme conditions to get big things done, but I don't think selecting for commitment can fix another problem: no plan is perfect, and they tend to get worse as the planner is separated in time and space from the action. On Earth, we make sure command structures are hierarchically self similar and afford some tactical autonomy to people in the field, even when we are asking them to put themselves in a lot of danger. Sounds like NASA was (is?) still working out what the level of autonomy and negotiation should be.
