Look, no one is claiming that you can have entirely "independent/impartial" news outlets.
Simply by virtue of being alive, we have egos and notions of the self. I can dabble further into the psychology, sociology, and philosophy behind it, but I don't have the time. Needless to say, humans take sides.
However, good news sources seek to be objectively reporting facts while admitting there may be editing problems - and quickly fix it. You hardly ever see MSNBC, CNN, FOX admitting they were "wrong". Even worse is when these groups attempt to pass editorials and opinion pieces as "news" ala Bill O'Reilly, Keith Olbermann, Chris Matthews, Glenn Beck. They are entertaining, but it is not news, and the masses buy it as fact almost unquestionably.
You must watch out for those news outlets which claim to be "objective" while reporting "opinions". I can tell you right now from The Economist website that there's an ad on the site directly from the news Intel group (which runs The Economist- how convenient) asking the loaded question "Is Obama failing? with a handy little graphic with checkmark box high profile issues"
If you don't realize that it is a loaded question -a logical fallacy which presupposes- insinuating an opinion within a supposedly innocent question/ad from a website which claims to be "objectively reporting news", then I can't help you and neither can this discussion. Asking loaded questions doesn't make The Economist strike me as "credible and reliable" and strikes me as just the sort of thing media news outlets do constantly.
Loaded Question: This is the popular Glenn Beck-ism "I'm not saying Obama is a racistObama is failing, all I'm saying is that we should be asking "is Obama a racist? is Obama failing?" because he might be a racisthe might be failing" - that Glenn Beck used extensively during the whole Birther debacle and continues to use - insert whatever you want in the blanks. There are much more objective ways to phrase the question, but of all ways they choose that one because they wish to influence the answer, or even if the answer is false, the opinion of the person receiving the question.
The point is, take all news, facts, and information with a grain of salt; study it from your past experiences, according to your belief systems, all the while applying reason to your observations - and wield it for the good of yourself and all. That's the important thing - to think for yourself - there are plenty of people who: seek to control what you think or limit it, want you to remain a slug incapable of critical thought giving them ad money, or don't care if you are happy being blissfully ignorant.
We educate ourselves so we can spot these sort of things.
