> It's remarkable that there is data about the outcomes of billions of lives, but we still have only vague indications about which behaviors lead to which outcomes. Do you really find that remarkable or is that just hyperbole? The fact that its so difficult to do controlled experiments - the holy grail of science - in this area in tandem with the fact that these are almost invariably complex systems we're dealing with makes it such that its not that surprising to me that we are still as confused as we are.
