It's fun, Enron. You got into this on principle and so did I. Neither of us disagree with the argument, only the way it was used.
Was just waiting for your reply.
Exactly, there is not way to tell. So you have to use your best judgement and do a little research on the sources of your information. Now using Wikipedia as an example, would you not question the validity of an internet encyclopedia?
Well, they do these experiments now and again to measure how accurate and reliable Wikipedia is. From that it transpires that it's actually comparable to sources like Britannica and in some cases more accurate. These are sample tests, noone's going to examine the whole thing. On the other hand Jimmy Wales isn't quite happy, because he says that the quality of an encyclopedia is measured by its lowest quality articles, and he was hoping to do better.
Nevertheless, I object to your implication that sources of information are black and white and thus dismissing Wikipedia out of hand. The fact is that it is considered an excellent source of information and aside from the fact that it is editable and open to vandalism and purposeful misinformation, that stuff gets taken out pretty quick because they are monitoring all the edits in real time. Wikipedia has over 1000 volunteers 'core staff' who have a ticker of edits in front of them and for articles that are frequently abused they keep a close watch on them. Compare that to Britannica having a staff of 1000 (or whatever) people who keep it up to date and factual, and what is the difference exactly? Are the Wikipedia people inherently more suspicious do you think?
There are stories about Wikipedia abuse quite often, where they identify a series of systematic edit from the same source and you read somewhere that some company (or members of Congress) is trying to mess with it. That already shows they can detect it.
Sure but why can't I criticize someone for using a source I think is less than? If I wanted to deny the existence of oil pipelines in the Middle East. I could have said "All those sources are biased". Did I do that? No.
Of course you can. There's nothing wrong with skepticism. I used to think CNN was a really good news source, now I don't trust them because of the regular reports of censorship and bias. That doesn't make me say "anything you might have seen on CNN is invalid". It doesn't make CNN "irrelevant".
This is not a black and white issue. Information is never pure. Wikipedia might be somewhat high risk because you never know if someone had just edited something that has yet to be peer reviewed. So maybe an article (or section of it) that hasn't been changed for a month is safer. Or maybe that's just because noone has looked at it yet. There's no way of knowing. But just because 5 phone numbers in your phone book might be incorrect doesn't mean the whole thing is useless.
