Well, I've actually read most of the 150 plus posts in this thread (although I did skim over the shortest ones), looked up various definitions of liberal and conservative (trying to determine what I should take as the general meaning of these terms as used by posters in this thread), read some of Chomsky's replies to his crtitics, reflected on my personal experiences growing up in the South and living in major metropolitan areas in the Northeast, the West and the South, and drawn from my personal experience of a couple of years (in my youth) on the city desk of a major metropolitan daily newspaper.
Here's my two cents. I think that journalists, for the most part, tend to be of a liberal bent. That is, they aspire to be objective, openminded, broadminded, advocates of the common working people that constitute the vast majority of human beings inhabiting this planet who want nothing more than the freedom to make an honest living and provide for their families, and in favor of progressive ideas and positive changes that promise to benefit mankind, in general. I think that most reporters would agree with the idea that the fundamental duty of every citizen in a democracy is to question authority -- in general, questioning the motives and veracity of statements and behaviors of elected, and appointed, officials.
Now, pick up your local metropolitan daily and look at what it offers. There will be prominent sections on society/celebrity, business, the stock market, classifieds, sports, entertainment, the funnies, local (mostly street crime) news, maybe a section on state stuff if the paper still has any 'state' reporters on its staff, and international news culled mostly from the wire services, and of course a few editorials. I can almost guarantee that there will be no real, in depth, investigations, articles or scathing editorials on the sort of crimes that ruin the lives of very large numbers of people, ie., white collar crimes, corporate crimes (such as the relatively recent 'financial sector' debacle), war crimes by the the US, or any sort of serious questioning of the motives of the people who have taken us into armed conflicts.
Anyway, reporters, in my personal experience at least, tend to be, themselves, liberal. That's a good thing, I think. Newspapers, on the other hand, tend to be, generally, conservative. That's, generally, not a good thing -- at least not in a society that purportedly values free and critical thinking, and the dissent that that usually entails, above more or less blind obedience to authority.
I sympathize with the poster who asked about the meanings of the terms, liberal and conservative (it can get confusing), and I agree with the poster who opined that the raison d'etre of newspapers (and news media in general) is to turn a profit. Everything else, especially investigative articles or editorials, that might get at or hit at the truth of things is subordinated wrt the primary goal of turning a profit.
By the way, for those who don't know, Ralph Nader was on c-span today. A three hour interview. (It will be aired in its entirety next week.) Is Nader a liberal or a conservative? Do these labels really matter when talking about such a person? Nader was generally marginalized and portrayed as either a joke or a 'spoiler' by the mainstream press during his runs for the presidency. How can a country that portrays itself as a bastion of free speech refuse to allow a man such as this to participate in debates with the other candidates?
Anyway, a discussion of the orientation of our news services can get rather deep. And, I assume that the people who populate those news services to be both better informed and wiser than I on international issues. I don't want to live in a world ruled by Islamic fundamentalists. I also don't want to live in a world ruled by Christian fundamentalists. Jewish fundamentalists I can identify with, although I don't really like what's happening in Palestine (and Gaza in particular). But I don't want to live in a world ruled by Jewish fundamentalists either. Anyway, is this part of the definition of 'conservative'? Some sort of religious affiliation? Is humanity on the verge of some sort or 'nervous breakdown'?
There is another, current, thread on 'energy'. Hopefully, this, or a similar collective problem, will be a reason for all of us to look, and see, past our 'ideological propensities' and work together to find a solution. Then, of course, we'll resume our petty regional and ideological and religious conflicts. But at least we'll be able to do it in a technologically advanced way for a really long time -- and most of us will be able to access the internet. And, after all, isn't that what's important?
OK, I got a bit off-topic here. But, look, Russ, you're a scientist. I'm a scientist. Everything's connected. Reporters, editors, producers, owners, even the 'talking heads' -- they're all human beings and therefore somewhat complicated. Ok?
What's the precisely correct answer wrt your OP? I don't know. Whatever you say, I'll take your word for it -- for now at least.
Edit: I should add that I think that liberalism generally connotes an effort to be as objective and unbiased as possible. I think that this is the orientation of most journalists, at least at the beginning of their careers. Conservativism, on the other hand, connotes an acquiescence to authority. So, the news media, at least the print media, while generally populated by liberals, are, ultimately, conservative. Unless the reporters are running things -- and I don't think that that will ever be the case.
