maybe i should elaborate: the common framing is "science can tell you what is, but even if you knew all what is, that wouldn't tell you what to do." and at this point many will offer some arbitrary source of "what to do", like culture, religion, government or "whatever you feel like".
but knowledge comes from action, there is no science without doing things, better in some ways than others. and to deepen knowledge, scientific practice needs to be refined.
