What? "Not meddling in things you don't understand" is a great principle. If you don't know what the fuck you're meddling with, any success is pure chance.
N... no, working when you don't really know what the fuck you're meddling in is basically the absolute most fundamental skill any high level administrator/manager/politician has to have to not be shit. They have limited time and a great many demands on it, which largely precludes an in depth understanding of the processes going on at ground level, and they have to use that time to make effective (or at least largely harmless, which in all seriousness making the game ratings have legal omph would be) decisions. And a great many do, and do so consistently. Many don't, as well, obviously, but that's what makes (one of the) major differences between a good manager and a bad one.
Depending on how you fall on the subject itself, her actions regarding the gaming stuff can be a mark for or against the skill in question. Most of us here count it as a mark against, obviously enough, but there's a lot of folks that wouldn't, and hold that she did the right research with the correct consequent action, including quite a few academics/researchers in the fields studying the phenomenons involved with video games and aggression. Hell, the APA just recently released a metastudy on the subject that suggests that current research favors the sort of course of action clinton took, that experiencing violence in video games is a reliable indicator of increased aggression and lowering or preventing access is a desirable goal. There's some notable problems with it, but that's still a hefty body of knowledge saying curtailing access to certain video games among the youth is probably a good idea. Largely disagree with the findings, myself, but I can understand (if dislike) how someone would act as clinton did, given that sort of research does exist and did when the event in question happened. It's a mark against, t'me, but not a terribly substantial one.
... really, as we should have noticed from the last few hundred years of sciencey stuff, you don't actually have to know what the hell's happening to get useful results. Admittedly it
is kinda' important to, because unexpected consequences are a thing, but it's not like there's not plenty of stuff we're buggering about with in good health that was brought about with basically zero comprehension of the underlaying principles. Ultimately, meddling when you don't know what the fuck is going on is how you find out what the fuck is going on. It's a good thing when it's done correctly. An actually good principle would be to meddle
carefully in things you don't understand, and try to receive the best results when you do.
