Jon Stewart and the outstanding writers at The Daily Show recently did an outstanding job illustrating the hypnotic effect of "talking points". These are the collections of short, sound bite-worthy phrases used by representatives of one side or the other (everyone shares the guilt here) all over the "news" channels to drill home a particular opinion.
Eventually, they hope people will hear the lines repeated enough that they blindly accept the statements as fact. Even better, they hope some of these drones will actually begin using the phrases themselves in speaking with their friends. "Talking points: they’re true because they’re said a lot."
One more reason to avoid the talking heads channels and find some actual news to read.
