I think you are severely overstating the level of knowledge of most journalists. Most science reporting to the public goes like this: journalist hears something, contacts a single scientist in the field, or is contacted by a single scientist. They talk to that person for a few minutes, then write their article. That's being generous, many simply copy press releases and add their own interpretation.

There are only a handful of decent scientific reporting agencies targeting the public that actually do a good job.
