We all know the media are biased. We see their biases most clearly whenever they say things or slant things or use loaded terms that are counter to our own personal views. And our perceptions of media bias are influenced by our personal views.
There has been a graphic floating around Facebook that, to my mind at least, doesn't recognize the left-ish elitist interventionist views of many of the major media. That graphic, in itself, reflects major biases.
Here, courtesy of Adrian Sjoberg, is that same graphic, redone to reflect what I think are better characterisations of the slants of most of the major media; he has also included a few from Canada (note: I would put the CBC even farther to the left than he did).
This graphic shows what I think many of my economist and libertarian-type friends believe: most of the major media are biased to the left, toward thinking that bigger gubmnt is better and that market failures are more serious than gubmnt failures.
Digression: some thirty years ago when I was teaching economics courses for working journalists, one prominent reporter for the CBC confided in several of us that she was really left-wing but that no one knew it. She was so unaware of her biases that she didn't know she was one of the people who stood out for us as being extreme left.
