The core problem with the news is that they know how to lie by telling the truth.
You can string together true statements that lead to a false viewpoint very easily. _This_ is the bread and butter of this awful media empire we have nowadays.
Vaccines contain cancer causing agents. Vaccines have crippled people for life. Vaccines have lead to children dying. Do you still want to get a vaccine?
All of those are true statements. But the whole thing is a lie.
I think the biggest lever is just what they decide to give airtime to. It's known that humans are extremely moldable by anchoring- whoever they hear from first they are more likely to trust, and repetition- whatever they hear most they are more likely to trust. Key arguments are picked in some weird process I have yet to figure out, and then 90% of prime airtime is going towards whether <1% of the population people should be able to identify as another gender instead of all the real stuff going on that people should be hearing about.
