More than half of Americans say they tend not to trust the press

That's one of the findings of a nationwide Harris Poll of 2,302 U.S. adults surveyed online between January 15 and 22, 2008 by Harris Interactive.

"Looking at the press in general, over half (54%) of Americans say they tend not to trust them, with only 30 percent tending to trust the press. Just under half (46%) of Americans say they do not trust television, while one-third (36%) do trust them. Somewhat surprisingly, Internet news and information sites do slightly better as a plurality of Americans (41%) trust them while just one-third (34%) tend not to trust them. And, radio tends to do best among Americans as 44 percent say they tend to trust it and one-third (32%) tend not to trust radio."

As for "trusting radio," are they referring to radio news or radio in a broader sense (talk shows, etc). And why does radio (and the net) earn higher trust than TV and newspapers?
