To work hard at collecting information, making every effort within time constraints to get correct information. To write clearly. It would take a lot more time to answer this one well. I'm not sure I understand the question. I would assume that if I do a story on a bill before the legislature, and I talk to two different legislators with different viewpoints, that people know this is an issue where people have different ideas.
People can listen and decide which viewpoint they agree with.
If I do a story on a crime, I talk to neighbors, the police, anybody I can get my hands on, and try to tell what happened. Stories like this change, because the police learn more as an investigation goes on. So I tell what is known at the moment. I assume people know that. I believe people are skeptical of some of the viewpoints presented.
