There is a story that has been going on for 5 years.. (actually 11 years). It has been ignored completely for about a year, but today it has again erupted into a firestorm. It is a story that I have special knowledge of, and it is only relevant to one country. It's not really a political story, so I don't mention it here.
BUT.. what has been published on the radio, TV, newspapers, and internet about this story today CLEARLY illustrates how stories propagate. The newest chapter of the story broke yesterday, and it contained two GLARING errors. Errors that are clearly errors, no opinions. That doesn't surprise me. What DOES surprise me is that today, all the other TV, newspapers, radio and internet reports are covering this story.. and including the SAME ERRORS!
So, what is going on is that media outlets are not researching their reports at all, nor are they verifying anything. They are just plagiarizing each other.. getting their "facts" from another bad source. Sort of like.. the New York Post getting their facts from the Washington Post.. that got their facts from the Chicago Tribune.. that got their facts from the LA Times that got their facts from some anonymous, erroneous source!
In advanced English classes in school, they torture students with the task of having to put footnotes all over the place that refer to the source of the information being presented in an essay / thesis. The news media should have to do the same thing, if not in the article they wrote, they should provide their sources on request. "Washington Post.. who told you that Trump has 7 toes on his left foot? Was it a reputable source? " And they respond "uh… it was the Chicago Tribune.."
In computer lingo.. we call that GIGO - "Garbage In - Garbage Out".
