The critical question is whether they could have such measures.

Do you mean they might create such measures in the future, and therefore we should keep funding them? But without such measures today, how do we know if they're moving towards that goal? And what's the basis for thinking it's achievable?

That's completely beside the point. The point is that you allow that the system cam outperform the individuals in the one case, but not the other.

Is there an empirical or objective standard by which the work of moral philosophers is judged for correctness or value, something that can be formulated explicitly? And if not, how can 'the system' converge on good results?
