Question title is clear now. Can you please also specify in the judgement rule what you want to define as "fix"?

Question title: I would support this question but there is a word missing here ... repair? restore? clean?
Judgement rule: "Long term study" is good, but the rule should say expressly what hypothesis the study should verify/falsify and at what level (e.g. in at lease one case, on the average, nearly almost, every time, etc.). Please modify as appropriate.
