The first habit many journalists follow when framing a story is to find conflict. Conflict is the chief ingredient of much news coverage. Republicans versus Democrats, Dole versus Clinton, Serbs against Croats. Conflict is an element in drama. Shakespeare's plays all are based on conflict.
Some journalists feel they have to dramatize the news.
Another journalistic habit is there are two sides to every story. But it is often misleading or inaccurate to force every story into a dramatic framework where there are only two sides, with only the experts from the most extreme points of view allowed on the air and into print, there to repeat their tired points of view. Take as an example abortion, the flash point of American politics for two decades. When there is a TV debate about the subject, we invite the people who espouse those extreme viewpoints and no one else. This despite the fact that even a superficial glance at poll data reveals the vast majority of Americans are deeply troubled about abortion and reject both those points of view.
