Ambiguous, leading statements allow a listener to assume the content in lieu of specifics.
In the spirit of the MSM's "Fake News" news lately, I submit a seemingly innocuous example: Of all of the "Supermoon" articles back in December(and priors), how many mention the fact that the closest full moonrise is indiscernable in size to the naked eye as the furthest full moonrise? Besides Phil Platt, I believe the answer is approaching 0. Yet, every MSM news site/channel promoted it as "the biggest in ~100 years", many webizens clicked the links, some even went out to watch it live and most now believe it appeared physically larger than any other full moonrise in ~100 years.
edit:added "in" to discernable.
swapped ~ for +/-.
