Unfortunately most mainstream reporters know very little about the topic they're reporting. They've been trained in journalism (which is debatable) and not the science, medical, financial, legal fields that they're reporting.It's an unfortunate aspect of contemporary media that feeds into the mis/disinformation. There is good science reporting, but more and more it is not the stuff that's just going to show up in the feed of your standard media outlet.
In a previous life I was involved in the investigation of financial frauds, some of which were high profile. Never did I see a report or article in regards to a case that didn't have major factual flaws.
