I think that's more of a concern when there is a principal-agent problem. Yes, if you pay me X $/widget but are unable to measure widget quality well, then I may try to maximize number of widgets produced at the expense of quality. (And it may make sense to use other incentive structures.) But if I'm trying to help people, it's much less likely that I'll stupidly maximize a metric (# of page views) by lowering quality. What have I to gain? (This of course because a problem as soon as you start tangibly rewarding me based on the metric, or if the metric influences my public reputation, etc.)
I see. But I think this "system that lets you see how what you do affects other people" should be applied to everything we do, not just charity. It should be mainly about your job and what you do that pays you.
I wanna say why I think this is a good idea, but I'm curious to know whether it's obvious to other people why this could be a good thing.
