Agreed that it says "MacRumors" right in the title, so sketchy stuff is to be expected. However, in general, the fact that a sketchy source turns out to be right right doesn't really prove anything about the source - a stopped clock is right twice a day (unless it's digital).Turns outs, that sketchy source was 100% right, making that thread a great example of why posting stuff, even sketchy stuff, is fine. Just as long as there is context to what is being posted.
E.g. based on my sources at Apple, I can reveal that the 2022 iMac will feature a 27" or larger screen and be powered by a M1 Pro or M1 Max processor, feature an SD reader and possibly a HDMI sockets, and cost at least $1799. Now there's a pretty strong chance that that will prove accurate (and I've added enough qualifiers to cover the most likely mistakes). It is "false" in the sense that my only "source at Apple" is the same MacBook Pro launch video that everybody else saw, yet I'm spinning it as if it was some sort of confirmation of what most people are guessing. And, yes, I can think of a few YouTube channels that specialise in that sort of fluff.
...then, in some cases, the controversy has not been whether the sketchy source is true, but whether it was right to reproduce or promote information that may have been obtained illegally. NB: I can't recall any cases where MR have directly reproduced "stolen" documents, but journalistic logic seems to be that once someone else has done so, it's officially On The News Agenda and it's OK to report on what they released. Hmm.
Funnily enough, this subject came up during my weekly poker game with Socrates, Jesus, Abraham Lincoln and Batman, and they all agreed that the question was "how do you know that a falsehood is obvious?" and that your example made the unlikely assumption that someone posted a blatantly self-contradictory resume. Socrates said that the best response is always a reasoned counter-argument supported by references - which also forces you to check your own facts just in case you have it wrong. Batman reckoned that it was OK to use ad hom attacks if you have cast-iron evidence that their credentials were false (but never kill them unless they accidentally fall off a roof before you can save them), but Jesus didn't think that was ever acceptable, even if they ad hom'd unto you (then he folded on three-of-a-kind). Abe pointed out that it also depends what they were saying - if it's a harmless matter of opinion then don't sweat it, but if they were suggesting something potentially harmful - like encouraging people not to wear a kevlar vest at the theatre - he was sure that the MacRumor's mods would look into it if you reported the post.I'm not talking about changing careers. I'm talking about obvious falsehoods.
So there you have it, from the people who really should know.
