There's a lot of vigorous dissent here because lying requires intent: One's statement(s) must be intended to deceive people. I think this formally/technically correct dictionary-wise, but kinda missing the point.

If your goal is to help people understand media better, they do need to know that most media deception is accomplished by simply avoiding relevant facts rather than voicing outright falsehoods. In other words, as a media consumer, your primary question should be, "What are they not telling me?" This is why it helps to multi-source your news.

That is a very instructive lesson to learn - something we should teach kids in school, really.
